I can see that you are attempting to help yourself. In this effort, first of all you have to regularize your meal times so that you eat small meals throughout the day. Staying hungry for too long can aggravate acidity and indigestion. Also, you need to eat healthy nd drink water, lemonade, fluids etc. Also, since your mother has ulcerative colitis, it is possible that you have inflammatory bowel disease.
In your case all causes of chronic diarrhea will have to be looked into. Chronic diarrhea can be due to parasitic infestations. Other causes are irritable bowel syndrome, celiac disease, Crohn’s disease, malabsorption syndromes, pancreatic diseases, diabetes, hyperthyroidism etc. If celiac, Crohn’s and other problems have been ruled out then lactose intolerance and IBS are the possibilities. Gas in stomach, burping, diarrhea all go in favor of IBS. Pancreatic enzyme disorders, liver dysfunction, HIV, cancer of the gut, and infections by parasites other than giardia can all cause persisting diarrhea. Lyme and lupus are other possibilities that present this way. Please discuss this with your doctor (GI doctor).
I sincerely hope you will find this information useful in your journey towards better health.
Hope you get well soon! Good Luck and take care!
Thank you for the advice. I started eating 3 healthy meals a day and my stomach has not given me anymore problems at all!
