Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns. As per your complain diarrhea and flatulence can be due to causes like stomach infection caused by bacteria or virus, while other causes can be disorders related to intestines like Ulcerative Colitis and Crohn s disease, side effect of medications it you are taking any,alcohol abuse, sudden cahnge in dietary habits like increased intake of fibre in high amounts, laxative abuse etc.. I would suggest you to consult a Gastroenterologist and get evaluated and he can do a thorough clinical evaluation and can also advise you blood tests, stool culture, endoscopy and colonoscopy to confirm the cause and treat you accordingly.. As og now you can take Furazolidone to relieve diarrhea and take a soft and light diet.. Take ample of fluids and if there is excess water loss you can take oral rehydration salt dissolved in water to recover electrolyte loss.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
