@sandy1234 - I recognize some of your symptoms.
I have nausea, feeling full, bloating (always), exhaustion and an increase in heart rate with minor effort. I also have on and off mid and lower abdominal pain. I don’t have pain when I sleep.
I think I have a relapse of gastrointestinal autoimmune inflammation, but it has not been confirmed. I’m trying to get a GI appointment.
I had similar problems about 10 years ago- always better if I for some reason was given prednisone. Eventually, I was treated with immunosuppressive meds and recovered for a few years until 2-3 years ago.
It sounds as if most of your symptoms are GI related. Fatigue and exhaustion are common with autoimmune diseases.
How long ago did you see a gastroenterologist?
There must be some explanation for your persistent nausea, pain and bloating.
Has your weight changed?
Has anyone offered trials of any medications- including prednisone- to see if you feel better?
In my case I pointed out to the doctors what I had noticed when given prednisone for my asthma- I felt better and bloating subsided. That’s probably one of the reasons they tried me on Budesonide by mouth- it’s given for intestinal inflammation.
