Horrible gastro symptoms for a year

Gender : female Age : 27 Medical background: pots , pcos , gastric polyps(removed 4 years ago) , hital hernia , rheumatoid arthritis

Meds : plaquenil , bisoprolol , nexium

What’s going on : Okay hello , so I’ve been dealing with horrible gastro symptoms for a year and a bit now , I’m chronically on pepto bismol because my doctor said I can’t be on anything else .

Why am I writing here . Well quite frankly I’m exhausted of being tossed from doctor to doctor and maybe someone here has an idea . My symptoms are alternating diarrhoea and constipation (yes even with ridiculous amounts of pepto daily) a lot of those times it’s diabrrhea and constipation mixed. Stomach pains , I can’t really eat anything anymore I can only eat 3 items or 4 that are okay with my stomach . I spend most of my day in the bathroom and unfortunately that’s not an exaggeration. Luckily for me I work from home so I just work from the bathroom.

I dropped a lot of weight in a very short time without really trying to . I went from 137 kg to 106kg in a few months .

I feel like my life isn’t life anymore and it’s just me and the 4 walls of the bathroom . What’s worse is doctors refuse to give me colonoscopy because I was given one for general checkup 2 years ago and it came out clear . That’s a whole year before symptoms even started .

Another important mention. I have unexplained severe anemia that won’t go away even with iron supplements.
