Feeling lethargic and needing to sleep after food? MCAS?

I don't think I'm the only ME sufferer who suffers this. I did think it was down to my angry stomach just relaxing and giving me some peace to rest. But I'm now wondering if it could be an unnatural immune response when food enters my bloodstream.

Unfortunately it has stepped up a gear in recent months.

I've been thinking this after hearing about MCAS (mast cell activation syndrome). Does it sound like it could be?

Also, for those already diagnosed with MCAS, how were you diagnosed? I mentioned it to my GP, but she'd never heard of it. Did you need a specialist?

Thanks.

Helps to have an immunologist experienced in MCAS (there's a few more these days) or at least a doctor who is somewhat familiar with the various tests and treatments (urine tests, cromolyn, ketotifen, etc).

What you describe could be related, or it could be anything unfortunately. You could try to get tested for MCAS, or if your doctor is willing, you could try cromolyn which is a mast cell stabilizer that focuses mostly on the GI tract.

Have you taken things like quercetin and bromelain and do they help any of your symptoms? If so, might be worth investigating MCAS.

I think I have a bit of MCAS, but also think for years I misjudged PEM as food reactions. I'd have a meal, then a few hours later I'd crash for a day. In retrospect, it was more likely the activity from a day or two before, but PEM seems so weird and counterintuitive that I think I always focused on food reactions. But it was frustrating because I'd have a food on Tuesday and be fine, same food on Thursday and I'd crash.

Allergists are a good choice who can give some information. An increase in the serum level of tryptase (a blood test), above baseline and within a narrow (generally accepted as one to two hour) window of time after a symptomatic episode, is proposed as the preferred method for providing evidence of mast cell involvement they can do. https://www.healthline.com/health/mast-cell-activation-syndrome https://tmsforacure.org/tests/ And histamine blood tests can show if it was high at that specific moment of the test.

One thing that helped me is I would keep a food journal of everything you eat, drink, and use (supplements, soap, shampoo etc) and when you have the symptoms to look for patterns. Also note the common ingredients especially sugar/fructose, spices or vitamins.

Thanks for the replies, sorry for not getting back earlier. Been a bit out of it with the nicotine patches.

No idea what either
quercetin and bromelain
are, or do, to be perfectly honest, and definitely never had them.

Pretty convinced it's food. It's like clockwork, I eat, within half an hour I'm dropping off to sleep. Sometimes, bizarrely feel the energy drain out of me as a sensation at the top end of my intestine. Sometimes it bizarrely feels like small explosions going on in there, and in my lower intestine.

@Andryr Well, apparently I'm pre-diabetic, but strangely my last blood test showed I had moved further away from diabetes.

@datadragon thanks. In regards to sensitivity to chemicals. I have a grey beard because the one time I dyed my beard black, I ended up with neuropathy, and have been stuck with it since. Although I believe it's common for ME sufferers, I'd had ME for the past 15-20 years without suffering it. It's not awful, and not painful, and I've got used to mentally blocking it, but it just feels like a 1,000 worms wriggling in my feet and legs.

@Judee Well, I'd say the nicotine most definitely increased my fatigue and lethargy, but I don't feel there was a sudden onset, unlike with this.

Thanks for the links.

Well, it seemed more inclined happen with certain foods, like sugary pastries. Also I suspect some specific foods like hazel nuts, I suspect. It can be hard to pin down, though. I've also never eaten oats for years because he would send my intestines into a mess. Coffee also messes me up - although, strangely, it doesn't seem to be the caffeine that's the culprit, as I get the same results with decaffeinated.

As I say, lately, it's gotten worse, and also the spectrum of foods now seems very broad.

Unfortunately what seemed to trigger this worsening, was I got double jabbed for flu and Covid (Pfizer) in the winter of last year, so I'm suspecting vaccine damage. I think I was also a little dumb getting both at once, as it gave my immune system more to contend with, but I wanted to make as few trips as possible.

I would be more inclined to suspect the flu jab, though, as my mother had had issues with it in the past, and I'd also been fine with my two other Covid Pfizer jabs. Really wish I hadn't got the flu jab, and I don't think I'll ever again.

Indeed, it is very common among ME sufferers.

The worst foods for me in that regard were dairy products like yoghurt and kefir, etc. I suspect it has something to do with the yeast and bacteria. Pastry, wheat-based food, and oats had a similar effect.

When I was on sertraline (and many other antidepressants), it significantly improved. Now, even a year after I stopped all drugs, I can tolerate pastry, milk, etc., although it still drains a lot of my energy. It's quite a daily dilemma for me - have some energy inside but feel extreme cravings for "forbidden" stuff, or consume some of it and not be able to function for a couple of hours or so...

I've noticed that supplementing with potassium helped me to tolerate dairy, gluten, and other "bad" foods better too.

Thanks. Well, I've really had it for years, but after the vaccines it's seemed to get quite a bit worse. I think I heard jabs can cause MCAS, which has made me rethink about this sleepiness after food.

I might have trouble, because I got two jabs at once, so I can't prove which is the culprit. I think also struggle without more evidence.

@Vladimir Strange how it varies. I seem fine with many of plainer foods, apart from oats. Milk and yogurt, I think I'm fine with. Also, although pastries and possibly also bread are an issue, I also seem fine with raw wheat, like Weetabix.

For me, it seems to be nuts are the worst for causing fatigue and anxiety. Well cashews and peanuts definitely. I haven't experimented with other nuts. I think eating too much refried beans also causes a similar reaction.

I thought it might just be high fat or high protein, but I can slurp down a bowlful of beef chunk and tallow soup and be fine.

Sounds just like me- i recently deteriorated from Mild and full time work to Moderate and housebound. The first NEW symptom as I deteriorated my baseline was Constant stomach noises asif i could hear everything and all the liquidy noises going through my gut and intestines with also a complete loss of appetite which is still pretty crap today 7 months later.
I found an amazing MCAS paper with treatments that was very very easy to read, ill have to find it and post it.
I tried the H1,H2,H3 but i cant recall feeling a huge difference. At the same time i was taking an antibiotic for a Parasite that was found but 2 months after that my stomach is still abit noisy randomly and my energy/fatigue is still 1/10.
The gut certainly is linked to how i feel but not necessarily the MECFS and the fatigue. But i fee like it relates to alot of symptoms like the Brain Fog, The facial Flushing and red dry skin and the muscle wasting/loss of 15kg.

Is yours also mostly active at night a few hours after dinner?
Im normally mostly tired just after brunch but normally after dinner i dont have the same tiredness feeling as i have with the first meal of the day.
