Hemochromatosis, haemochromatosis, and iron overload redux

Haemochromatosis: the most common genetic killer of folk from the British Isles and their descendants

Back in 2008, while I was living in America, a big word became a big part of my life: hemochromatosis, pronounced he-moe-kroe-muh-TOE-sis (spelt with an extra 'a' in the UK and Australia). 

According to the Mayo Clinic, hemochromatosis is a "condition that causes the body to absorb too much iron from food," commonly referred to as iron overload. Most cases of hemochromatosis are due to a genetic condition, referred to as hereditary hemochromatosis in America (HH), and genetic haemochromatosis in the UK. 

The problem with excess iron is that our bodies store it in our organs, especially the liver, heart, pancreas, and joints. This causes damage to those organs and can lead to life-threatening conditions, such as liver disease, heart problems, and diabetes. It can also cause life-limiting conditions like chronic fatigue, severe depression, and loss of libido. 

Yes folks, despite the fact that our bodies need iron, and having too little iron can be a serious medical problem, iron is one of those things of which a person can have too much. Unfortunately, iron overload can occur "naturally" in  people who have certain genetic mutations that affect a particular gene that plays a central role in regulating iron absorption in the body. 

The gene genie

The gene is known as HFE and referred to as the Homeostatic Iron Regulator (see notes below for an explanation of why it is called HFE and not HIR). 

Just to be clear, there are several ways in which a person may develop hemochromatosis other than inheritance, but hereditary hemochromatosis, sometimes referred to a HFE hemochromatosis, accounts for the vast majority of cases.

But why is this big word in my life? Short answer: in 2008 my wife found out she has it. Also, she has suffered greatly from it and there's no cure for it. 

Furthermore, numerous members of her family had/have HH. To top things off: iron overload is seriously under-diagnosed in many countries, despite the fact that detection of it, and treatment for it, are relatively inexpensive.

Here's more clarification: not everyone who has the genetic mutations referred to above develops iron overload, and the percentage of those who do — referred to as penetrance — is debated. More recent studies are finding higher levels of penetrance, reflecting the still evolving understanding of how much damage iron overload causes.

Awakening and awareness

Here's what happened after my wife found out she had hemochromatosis: we researched it. We found that it is more common than most doctors have been led to believe, and that early diagnosis can prevent some of the symptoms that were plaguing my wife. 

We felt we had to do what we could to increase hemochromatosis awareness. Because she was quite ill at that point I took the lead and posted this on my blog: What Am I Thankful For? A diagnosis of hemochromatosis. That was Thanksgiving Day, 2008.

One of the first reliable source of information we found was the Iron Disorders Institute, a non-profit organization founded to address health issues arising from both excess iron and too little iron. The institute coined the term Iron-Out-of-Balance™ to describe this. Here's what the Iron Disorders Institute home page looked like in 2008, by which time the institute had been on the web for 10 years.


An impressively early adopter of digital technology, the IDI offered a range of free literature, prepared and reviewed by doctors. These PDF files were easy to print out and covered topics like: Hereditary Hemochromatosis Starter Kit, Hereditary Hemochromatosis Family Tree, Phlebotomy Guidelines, Genetics Worksheet. Over the years these have revised and update. Check out the current forms and charts page.

Some of the documents were designed to be handouts you could give your doctor, a great strategic approach to awareness and education given that many primary care docs and GPs have had little training related to hemochromatosis. I've lost count of count of how many times I have directed people straight to the Hemochromatosis Diagnosis Algorithm which includes the detailed guide to Hemochromatosis Clinical Management. 

During 2009, as Chey was undergoing gruelling rounds of blood-letting — the first line of treatment when someone has iron overload — we got to know the IDI's leader at the time, Cheryl Garrison. It is hard to think of a person who has done, or imagine a person who could ever have done, more to raise awareness of hemochromatosis than Cheryl. 

Apart from anything else, Cheryl wrote the book on eating right when coping with iron overload. Fortunately for us, The Hemochromatosis Cookbook actually came out in 2008 and we got a copy right away. We read the book and everything on the IDI website. Then we corresponded with Cheryl and attended several IDI meetings and conferences. 

I learned a lot during this time, from experts in the condition and people struggling with the effects of iron overload and its treatment. The latter, intense rounds of blood draws—technically termed phlebotomy or venesection depending on geography—can be exhausting and may get complicated. For example, veins get scarred and hard to find. In Chey's case she was fitted with a port, an internal medical device, also known as a port-a-cath or implantable port, that lies under the skin and connects to a major vein. 

Particularly worrying were the many tales of missed and delayed diagnoses that led to avoidable and needless suffering among patients with iron overload due to HH. This reality was reflected in a 2008 study by the Centers for Disease Control and Prevention (CDC) that found it was taking approximately 9.5 years from symptom onset for a patient to be diagnosed with hemochromatosis. That tracked closely with Chey's experience. 

Frankly, I was shocked by the extent to which so many doctors lacked knowledge of, or interest in, iron overload and hereditary hemochromatosis. Indeed, I came up with a cynical hypothesis: the profit-based American medical system was not interested in hematosis haemochromatosis because the treatment, namely phlebotomy, was cheap. On the other hand, if pharmaceutical companies ever developed a pill that could be prescribed to people suffering from iron overload, then there would be billboards to raise awareness of hereditary haemochromatosis all over daytime TV.

Taking action

By the end of 2009 I was read to launch my own efforts to raise hemochromatosis awareness, starting with a Facebook page. To the best of my knowledge this was the first such page on Facebook and I got the URL facebook.com/Hemochromatosis. Bear in mind that I was living in America at the time, hence the spelling.

This page, which I titled Fighting Hemochromatosis quickly attracted a lot of likes and followers (now at 10K and 11.1K respectively). I spent many hours responding to questions from visitors to the page. And I read dozens of disturbing personal stories people shared, further reinforcing my opinion that the medical community was failing, almost completely, to address a distressing and all too often deadly genetic condition.

The hemochromatosis Facebook page also showed me that a greater range of educational materials about the condition was needed. There was also a need to keep information fresh and updated as new developments occurred in the field of hemochromatosis.

To help meet these needs I launched a blog in June of 2010. I called it Celtic Curse, because that is one of the names by which haemochromatosis is known, arriving from its prevalence amongst people with Celtic roots. The first post was not lacking in ambition: The Work Begins Here: Teaching the world about the Celtic Curse. BTW, another old term for hemochromatosis in bronze diabetes, due to the tendency of iron overload to cause diabetes and skin discoloration resembling a tan.

Armed with a Google News Alert to catch fresh stories about haemochromatosis, I began to populate the blog with information. I cross-posted useful articles to the Facebook page and of course used a Celtic Curse account on Twitter to further spread the word. I experimented with paid message promotion on both Facebook and Twitter. (it didn't hurt that during this time I was helping a dear friend of mine advertise his digital advertising software, frequently rubbing shoulders with pioneers in digital marketing.)

Indeed, my involvement in "evangelising" haemochromatosis awareness got to the point where the Iron Disorders Institute and I were discussing a paid role to do the work full time; hence the business card seen here. Unfortunately, making that a reality meant finding funding for such a role.

Reality intervenes

By the time 2011 rolled ground, it was clear that Chey's body had been so heavily impacted by iron overload that she would never be able to work again unless there was some extraordinary breakthrough in medical research. (And such a breakthrough seemed increasingly unlikely given how dismissive I had found most medical professionals to be about haemochromatosis.)

Our prospects were further hampered by the fact that the mortgage fraud crisis and the economic crash caused by the ensuing banking crisis had wiped us out financially. So when I received, out of the blue, a relatively lucrative job offer from a respected security software company, I took that over pursuing a role in the fight against hemochromatosis. In order to maximise my returns on that opportunity, I had to cut down on the time I spent supporting the Facebook page and the Celtic Curse blog.

By 2019, we had made something of financial recovery and Chey's research into medicinal cannabis had yielded some positive results, not as a cure but as an aid to coping with her symptoms. This was facilitated by the fact that the aforementioned job was in California, a stat that has somehow managed to climb up the global economic charts despite letting residents consume cannabis legally. (california is now the fourth largest "country" in the world based on GDP, behind only Germany, China, and the United States itself, surpassing countries like Japan, France and the UK.)

We decided that I would retire and we would move to the UK to be near my mother who turned 90 that year. That's basically what we did; but unfortunately, during the process, which was made extremely stressful by Britain's vicious anti-immigration regime, Chey suffered a subarachnoid haemorrhage. That, and a second haemorrhage during Covid lockdown, further impeded my ability to maintain my online campaign to promote awareness of haemochromatosis. 

While I have embraced the role of carer for Chey—caregiver in US parlance, unpaid carer in UK terms—it does require a lot of time and energy. That is why I have begun the process to hand over some of the digital hemochromatosis awareness assets I have generated to an entity that can properly leverage them.

Further hemochromatosis fallout

There continue to be some bright spots as well as dark moments in the haemochromatosis story and this has always been the case. On moving back to my native island, I found that a charity called Haemochromatosis UK is doing excellent work in both awareness raising and support of haemochromatosis patients and families. They have helped push forward valuable research.

I have also found that researchers here are open to the idea that haemochromatosis is not just about discovering someone has too much iron in their system and then bleeding it out. It may be a lot more complex than that. There are indications that haemochromatosis can be a factor in long-term fatigue, despite iron levels being controlled. Better understanding of that might lead to improved treatment options and a higher profile for haemochromatosis in patient diagnosis, given that the UK medical establishment does tend to back efforts to reduce the occurrence of conditions that impose a burden on the national healthcare system.

I am also hopeful that the under-explored connections between fibromyalgia, sexual dysfunction, suicide, and haemochromatosis may get long overdue attention. 

Finally, I should mention the one aspect of haemochromatosis that I have gone out of my way to address: hemopause. This is a word I made up to describe a syndrome which is very real, namely the tendency for doctors to dismiss the symptoms of haemochromatosis as menopause in women of a certain age. As you might expect, I made a website about this

I identified the hemopause syndrome while processing the many accounts of visitors to the Facebook hemochromatosis page, comments on the Celtic Curse blog, and real life encounters. Hemopause arises from the overly patriarchal nature of medicine in the US and UK, and the prioritising of profit over patients in America. It also exemplify what can go wrong when a profession is dominated by males and male attitudes and thus, on the whole, disinclined to take seriously enough the pain and suffering of females. But that's a whole other awareness campaign and website!

Notes

The gene known today as HFE was first identified in 1996 by researchers seeking the genetic cause of Hereditary Hemochromatosis (HH). They found it on the short arm of chromosome 6 in a region known as the Major Histocompatibility Complex (MHC). 

(These are all terms I encountered for the first time back in 2009 when there were lots of thing I didn't know about genetics, like chromosomes have arms. Sadly but truly: there's nothing like a loved one getting disabled by a genetic condition to shove you up a learning curve.)

Apparently, this MHC region is home to many genes related to the immune system, including the HLA (Human Leukocyte Antigen) genes. Because the new gene's sequence looked similar to HLA class I genes but was distinct, it was initially named HLA-H (meaning an HLA-like gene). 

Unfortunately, the name "HLA-H" quickly became problematic because of confusion with the well-established HLA system. Geneticists thought name could mistakenly lead people to assume HLA-H had a primary function in immunity rather than iron regulation.

Another fascinating thing I learned from researching HH is that there's an official gene nomenclature committee (HGNC). It decided HLA-H needed a unique, unambiguous name that reflected its function rather than just its location. 3. Creating the "HFE" Acronym

The researchers and the nomenclature committee decided to change the name. They created the acronym HFE from the H from HLA, followed by F from the suggestion that it might be related to the F gene in the MHC region (though this was not confirmed), then E from its potential similarity to the HLA-E gene. Thus we have HFE, the Homeostatic Iron Regulator.

DefCon 33 arrives, my talk from DefCon III survives

The T-shirt I bought at my first DefCon, which was DefCon III in 1995

DefCon, the very popular annual hacking conference held annually in Las Vegas opens today, August 7th and runs through the 10th. This is DefCon 33 and I'm a bit sad I can't be there. This would have been an anniversary event of sorts, the 30th anniversary of my first Defcon talk. And I will miss seeing all the folks I know that will be there this year.

The good news is that Jeff Moss—the founder of DefCon—had the wisdom and the foresight to insist, even back in 1995, that all talks delivered at Defcon be archived. That means anyone with an internet connection learn from past events, which is great because in my experience DefCon never fails to deliver cutting edge information about digital technologies, how they work, how they don't, and what that might mean.

More than a few times I have used the DeCon archives to find out when a particular vulnerability was discovered or explotied for the first time. 

As a big believer in learning from history rather than repeating it, I like to debunk statements like "we had no idea criminals would exploit our technology like that."

Really? You mean nobody from your security team went to the session at DefCon X where exact same exploit was demonstrated?

And on a personal level, those DefCon sound archives mean I can still listen to what I said, 25 years ago, preserved as an audio (.m4b) file. 

If you want to listen, just go to the DEFCON III Archive and search for Cobb. My talk was titled: The Party's Over: Why Hacking Sucks. Alternatively, you may be able to listen in your broswer (not all browsers are supported). The talk is about 49 minutes long and while the sound starts out rough, it quickly gets better.

My goal with this talk was to generate dialogue about the ethics of hacking, and I think I succeeded. In fact, the audio captures that quite well. As someone who had been working on the computer security problem since the 1980s, I have to say that I learned a lot from that 1995 session and appreciated everyone's input. The feedback from the audience must have been okay because I was invited back the next year

A Cobb in a Kilt, 2018, DefCon 26, 
My talk at DefCon 4 in 1996 was about how to go from being a hacker to being an infosec professional. The title was 101 Things to Do With an Ex-hacker. Like many early DefCon talks this one took some unexpected turns. For example, I talked for a bit about trainspotting, not so much the movie as the hobby in which you try to see as many railway locomotives as possible. 

Trainspotting was one of my hobbies when I was a boy, back when steam engines were still is service. My point was that in our enthusiasm to explore this fascinating pre-digital technology we would sometimes break the law and trespass into locomotive sheds.

The parallel with hacking was that despite this illegality, some of us matured into respected professionals with rewarding careers. Indeed, one of my fellow trainspotters has had a long and fulfilling career writing and editing books about trains. 

Anyway, the talk lasts less than 30 minutes and might be worth a listen, eve if it's just as a historical curiosity. However, before you click this link to that talk be warned that there is some swearing, albeit in a very polite voice.

Over time, the Defcon archives have evolved to become a quite amazing cornucopia of knowledge and history, a feast for eager minds, and a legacy for future generations. 

Thanks Jeff and DefCon! Thanks your foresight!

And please accept my apologies for not being their this year. I will be keeping an eye on things from 5,000 miles away in Coventry, England, where I'm looking after my mum (96) and my partner Chey, herself a Blackhat speaker (Why Government Systems Fail at Security, 2001).

P.S. For more about Chey and her current condition, you may want to read this.

What's Amusia Got to Do With It


A few years ago I learned that I have something called congenital amusia, an inherited condition that can make it impossible to carry a tune or learn to play a musical instrument. In other words, amusia is tone deafness, or to use a derogatory expression, tin ears.

Amusia is defined as: "a musical disorder that appears mainly as a defect in processing pitch but also encompasses musical memory and recognition" (Wikipedia). Some studies suggest that as many as 4% of people are born with an innate inability to recognize musical tones or to reproduce them. This is referred to as congenital amusia.

In 2018, advances in genetics led me to discover that my lifelong failure to sing or learn guitar —despite great effort—was due to congenital amusia, not some weird character defect (although you can still find music coaches who insist that amusiacs are just being lazy).

When time permits, I plan to blog about my own journey with amusia, but in the meantime I put up a separate website —4Amusia.com— to curate links to information about amusia. Those links should not be taken as endorsements of the content to which I link, and the look and feel of the site may change over time; however, I am also color blind (deutan), so please excuse any jarring color choices you may encounter there.

You might be surprised at how many things can be affected by amusia, like some forms of speech and comprehension. The leading researcher in all things amusic is Dr. Isabelle Peretz and if you're interested in this topic her website is the place to look. It features a link to an online hearing test that you can take to diagnose amusia.

For myself, the stigma of being a tone deaf child was unpleasant, and the decades spent failing to learn a musical instrument were frustrating. At times I experienced deep sadness at not being able to express my feelings in song in the presence of other humans. Nevertheless, learning that there is a physical basis for these limitations, rather than some character defect, was quite liberating!

Happy 2025!

Welcome to a new and potentially extraordinary year. I am looking forward to making some long overdue changes here on the blog for 2025. 

As you can see Lola is looking forward too.

In many ways 2024 was a tough year for me and my family. I hope to find time in the coming months to share some of the lessons I've learned from dealing with those challenges, even as some of them continue to take a toll.

In 2024, I discovered several things about myself. For example, it turns out I am a cat person, even though I have never sought to get a cat as a pet. This might not sound like a life-changing revelation, but the fact that you can still learn stuff about yourself, even when you're in your seventies, well I find that encouraging.

Here's hoping we all have a great year in 2025.

Beastie Boy the hummingbird

Photo of a hummingbird, all puffed up and sitting on a balcony rail
One of the things that has helped me get through 2024 is the ability to look back, with very little effort at the many pictures I have taken in years gone by.

Sometimes it is the subject of the photo that gives me a lift. Other times it's the fact that I was able to get the shot. 

This photo of a hummingbird that we named Beastie Boy is one of those other times. 

Beastie is the hummingbird that hung out all year-round on our 14th floor balcony in San Diego, circa 2012-2016.

I tried to capture a good portrait of him for nearly two years. While this one is not perfect, I think it was my best effort, and a pretty good result considering the inexpensive gear I used: a five-year-old Olympus Pen E-P1 digital camera and some "classic glass," a 20 year-old Olympus 200mm Zuiko OM lens.

If the bird in that photo looks too fat to be a hummingbird, you've just learned something I didn't realize about hummingbirds until our balcony gave me a chance to study them: their appearance can change a lot. In the photo above, Beastie has fluffed up his feathers to create insulating pockets of air because the weather is cold (yes it can get cool in San Diego during the winter months, and Beastie chose not to migrate south).

The changes in hummingbird appearance can also be subtle and quick. The two images below were snapped with just seconds between the shots. 


For fellow photo geeks these images were captured with a handheld Olympus E-P1 (circa 2009), sporting an adapted manual F4 OM 200mm lens (20 years old at the time, $50 on eBay), shutterspeed 1/500 at f5.6, 1600 ISO. For more on old lens or classic glass click here.

Hummingbirds are one of the things about San Diego that I miss, so I'm very glad I spent some time to learn about and photograph them.

The Welcome Page

This post used to be pinned to the top of the blog but I decided to let it move down the stack. It's purpose was, and still is, to explain that I am Stephen Cobb and this is my personal blog. 

The blog was set up in 2005 but I didn't start regular blogging on it until 2006. That's because I had another blog, also started in 2005, where I covered my main interest back then: information security.

Over time, this blog became a place to talk about things other than cybersecurity. Things like dealing with several medical conditions: my primary aldosteronismbasal cell carcinoma, and very low grade prostate cancer; also my partner's hemochromatosis and Giant Cell Arteritis (UK readers can just add an 'a' after the 'e' in the hemo words).

Brief notes on 70+ years of life

I was born in a house in the medieval city of Coventry, in the middle of England, in the middle of the last century, to parents who survived heavy aerial bombardment in the global conflict known as World War Two, which ended seven years before my life began. 

After going to university—first in Leeds and then in Canada — I travelled the world for several decades before moving back to the city of my birth with my partner and our adopted cat, Lola (seen above).

My partner of 39 years, the phenomenal Chey Cobb, is a US citizen, legally resident in the UK. I am a citizen of both the UK and the US. We have both spent, and continue to spend, a lot of time researching how humans create and confront technology risks and health challenges. I write about my research for a variety of websites and publications, like:
This blog is where I write about more personal stuff such as: the fact that I'm retired, although I'm still open to interesting projects; my plans to publish another book, but I'm not sure when; my attempts to raise awareness of the medical problems which disabled my partner; the role of registered carers and how it can be supported; my hopes for radical reform of the patriarchal medical establishment that continues to fail women so badly. 
Photo of a Minolta lens on my Olympus camera

On a lighter note, Chey thinks I should have a hobby to take my mind off things, so I'm been trying "classic glass" photography: using lenses from old 35mm film cameras to take pictures with modern digital cameras (for example, the Minolta lens on my Olympus camera shown here).

On a more serious note, I feel the need to use some of my "free" time to contribute to society. So in addition to sharing my knowledge about thwarting digital criminals, I serve on the board of a charity, Carers Trust Heart of England

I also do driving jobs for our local hospital as one of the hundreds of UHCW Volunteers. As I travel around Warwickshire collecting and delivering patients I engage in another hobby: sampling independent coffee shops and their menus.

Fortunately, I still find some time to continue my research at the nexus of ethics and technology. I am currently exploring the harm caused by abuse of technology, which I have written about here. and talked about here, on YouTube.

Giant Cell Arteritis: Watch out for this nasty disease if you're female and over 40

Photo of woman in distress by Camila Quintero Franco. Thank you for making this extraordinary photo available on @unsplash

Women in their 40s or older need to be aware of a condition called giant cell arteritis or GCA. This article explains why. I'm not exaggerating when I say that knowing about GCA could save someone's sight, or even their life.

GCA is also known as temporal arteritis because, when you have it, "the arteries, particularly those at the side of the head (the temples), become inflamed." As NHS England states, GCA is "serious and needs urgent treatment."

What does GCA do? It causes multiple problems, including: "persistent, throbbing headaches, tenderness of the temples and scalp, jaw pain, fever, joint pain, and vision problems." That's according to the Vasculitis Foundation, which echoes the NHS when it warns: "Early treatment is vital to prevent serious complications such as blindness or stroke."

But wait, there's more: GCA often causes drenching night sweats, a symptom that can also be caused by menopause. And that's why women over 40 need to know about GCA. Sadly, far too many doctors tend to dismiss any symptoms suffered by women over 40 as "just menopause." And some doctors will say that to women in their 50s, 60s, and even 70s (for menopause neophytes, the menopause as the Brits refer to it, is over by 50 for most women).*

To be clear, most cases of GCA occur in people over 50, and the "peak group" is those between the ages of 60 and 80 years. That's according to PMRGCAuk, the leading GCA support organization in the UK.

It's not always menopause

Image by @Ageing_Better from their age-positive image libraryIf you know many women who are nearing or have turned 50, you may already know that this demographic often gets a particularly raw deal when it comes to healthcare. This is a result of two factors. First, there is a massively patriarchal bias throughout the medical world. Second, multiple diseases produce symptoms similar to those of menopause. 

I found this to be true, and truly problematic, when I started researching something called hereditary hemochromatosis about 15 years ago. This genetic condition can cause menopause-like symptoms in women who have gone through menopause; but many doctors have been taught—erroneously—that hemochromatosis is a young man's disease, even though older women can suffer and die from it. The result? Hemochromatosis in older women is often missed until it has caused them serious damage. (See the "hemopause" website for more details). 

When it comes to GCA, consider the main early symptoms, as described by PMRGCAuk: "headache, feeling generally unwell, weight loss, drenching night sweats and loss of appetite." You can well imagine a woman going to her doctor with those symptoms and being told one of the  following:

  • It's just menopause
  • It's just perimenopause
  • You're just post-menopausal
  • You're just rundown/overworked/stressed

What the doctor should do is ask the patient if they have any:

  • Pain over the temples
  • Double vision, loss of vision, or pain behind your eyes
  • Difficulty opening your mouth, or pain when eating
  • Scalp pain or tenderness

Those are four indicators which, when taken with the initial symptoms, suggest that the patient may have GCA. (Medicine Today) This suggestion needs to be taken very seriously, given that untreated GCA can cause blindness and stroke if not treated swiftly. Heavens knows how many women with those symptoms have been fobbed off with: "it's just the change."

Further GCA Information

How serious is GCA? This article written about 10 years ago for doctors in New Zealand is quite clear on how seriously GCA needs to be treated: "Giant cell arteritis, also referred to as temporal arteritis, is a form of vasculitis which predominantly affects older people. It must be treated urgently, as it is associated with a significant risk of permanent visual loss, stroke, aneurysm and possible death." (Best Practice Advocacy Centre New Zealand

Who diagnoses GCA? If you have a good GP (UK) or primary care doctor (US) they may recognize the early signs of GCA and refer you to a rheumatologist. If you are seeing an eye doctor because of pain in one or both eyes, or a sudden and significant reduction in vision, and they can't find a cause for these symptoms within your eyes, they may suspect GCA and refer you to a rheumatologist.

A more scientific description: "Giant cell arteritis (GCA), also called temporal arteritis, is an inflammatory autoimmune disease of large blood vessels. Symptoms may include headache, pain over the temples, flu-like symptoms, double vision, and difficulty opening the mouth. Complications can include blockage of the artery to the eye with resulting blindness, as well as aortic dissection, and aortic aneurysm. GCA is frequently associated with polymyalgia rheumatica. (Wikipedia)

Illustrated medical deep dive: Highly technical article, Giant Cell Arteritis: A Case-Based Narrative Review of the Literature

GCA is a form of vasculitis: "Vasculitis is a family of nearly 20 rare diseases characterized by inflammation of the blood vessels, which can restrict blood flow and damage vital organs and tissues." Vasculitis Foundation

Who gets GCA and why? "GCA is the most common form of vasculitis in older adults, affecting people over 50 years of age, with an average onset of 74 years of age. Women are more than twice as likely to get GCA than men. The condition is mostly seen in people of Northern European ancestry and is rare in other ethnic groups such as Asians and African Americans. GCA prevalence is estimated at 278 per 100,000 people in the United States over the age of 50.

Beware of rare: The word rare can be tricky. For example, both GCA and hemochromatosis are said to be "rare in people who are not of Northern European ancestry." But people who self-identify as Asian and African American may still get GCA. Also, GCA is also said to be rare before 50, but there are younger people who have it. Remember this, just because textbooks say X is rare, doesn't mean you don't have it or shouldn't be tested for it.

UK support group: https://pmrgca.org.uk/

More about symptoms: "The main early symptoms of GCA are headache, feeling generally unwell, weight loss, drenching night sweats and loss of appetite. Over time, the blood vessels on the side of the head can be visibly swollen with tenderness on touch.  Things like brushing your hair may become painful. In more advanced cases, people may find difficulty in chewing. Typically, it is chewy foods like a piece of chicken or a hard piece of toast that cause problems. The chewing becomes progressively painful rather than being painful from the first bite. If ignored, the condition can affect either part or whole of an individual’s eyesight. Very rarely, individuals may not notice any early symptoms and develop sudden painless loss of vision." https://pmrgca.org.uk/

* I realize that the "timing" of menopause varies greatly, but I sometimes think that statements like "menopause can last into your sixties of seventies" arise from doctors attributing symptoms to protracted menopause rather than digging a bit deeper into the diagnostic toolkit. My partner first presented to her doctor with GCA-like symptoms when she was 45. She was finally diagnosed with GCA at 70.
