Talk to Gastroenterologist on Ulcerative Colitis ?

Aoa its been almost 3 years since this problem started with me. This all started from food poisoning i had severe diaheria. I went to a hospital they treated me for 2 hours and sent me home after that i had symptoms of abdominal cramps and loose motion about 3 times a day. After that i met a lot of doctors, specialists, homeopathy, Dawa Khanas, Hakeems etc none could even diagnose the problem i have. I believe i have UC with upper abdominal problems too. I have done all my tests and nothings goes wrong except my platelets drop and my d levels also drop after every 2 3 months i take sunny d capsules to control. My symptoms are: 1 Immediately bloating after eating and consistent burping till all my food get digested and im hungry again 2 Loose motion minimum 3 and maximum can go to 6 if im constipated (with loose) 3 Gas build up more frequently at night 4 Swelling in lower and upper abdomen you 5 Even after drinking i have urge to burp and it takes time for water to reach stomach
