Hello, Thank you for your query. Stomach ache and frequent stools could be due to a number of gastrointestinal disorders including gastric/duodenal ulcers and IBS. To help answer you better, I would like the following clarifications :- -how old are you? What is your height and weight? -do you smoke or consume alcohol? -are you a vegetarian? -do you have a high stress job? -do you have any other medical conditions or take any other medications? -Have you had any blood tests or scan or endoscopy /colonoscopy procedures? -how is your stoolstool? Consistency? Any mucus or blood? -any fever or abdominal pain? -any distention /bloating right after meals? I recommend - blood tests (complete blood count, kidney & liver function tests) - endoscopy and colonoscopy to rule out ulcers, inflammatory bowel disease - ultrasound of the abdomen to look for any gall stones , increased size of liver/spleen. -a stool and urine analysis Based on a detailed medical history, clinical exam and results of the above tests, we could arrive a thin a proper diagnosis. In the meantime, -maintain a diary of the foods you eat and write down when your symptoms occur or worsen -avoid refined grains, carbonated /sugary drinks. -limit caffeine intake to 1 cup a day. -drink at least 3 liters of water a day (if not contraindicated by any other medical condition you may have) -eat more frequently but smaller meals and chew your food well. - avoid reusing oil, eating out, fried /spicy/oily foods -include fresh fruits, vegetables and whole grains (a variety rather that a single one) -avoid having water with meals upto an hour after as well. Small sips if necessary. Hope this helps. Please let me know if there is anything else I can help you with. Wish you good health
