Mine is MCAD, a mast cell activation disorder.
It is also lifestyle altering and I suspect there is another factor involved in this based on my research into it but cannot get any doctors to address my suspicion.
I’ve always reacted to foods with eczema and (in hindsight) other reactions. Spent my whole life being told I was a hypochondriac.
In my late 30’s, the condition started to deteriorate and my reactions to foods got worse to the point where some foods started dropping out of my diet.
It continued over the last 17 year or so getting progressively worse until I am to the point of being able to really only eat oats and chicken, beef, lamb, or venison.
I can eat a mouthful of some other foods on occasion, but not nearly enough to keep me alive should the oats and meat go too. I have no clue if they will also eventually drop out of my diet.
There is NOTHING medical science can do for it. I do have medicines they are having me on which do not appear to be making any difference. Even if they did, it would just be managing it for a while longer.
So, I’m looking at three possible scenarios.
1) God heals me.
2) Nothing changes and I live like this the rest of my life, another 20-30 years.
3) It finally progresses and takes me out.
#1 is the preferred option.
IMO, #2 is the worst case scenario.
It almost sounds like you are having an allergic chain reaction. I suspect the meddling with the food chain over the past few decades has triggered some of these issues you describe. Much in the same way advances in technology have caused triggers for mine. Mainly the foods I have to stay away from have MSG or almost any processed meats. When I was a kid I could eat bologna and loved it. Now it literally makes me bend over double in a matter of a few minutes. They radically changed the way it is made using parts of animals not previously used and adding chemicals not in our food chain four decades ago.
