HI. Thanks for your query. As per the history you have provided you are already suffering from IBS and Crohns- It may be either of it. You are bleeding in intestines in spite of the medicines means you need to get a review. I would advise you the following: Get an appointment with the Gastroenterologist Get a colonoscopy and biopsy to prove what exactly is the problem. Histopathological diagnosis is very important as the treatment of both the diseases is different. I would advise the following investigations and treatment in a such a case: Investigations: *Routine blood investigations like Complete blood picture, blood sugar, urea, creatinine, liver function tests, thyroid function tests. *Urine -routine and microscopy *Stool: routine, microscopy, occult blood, culture and sensitivity. *Ultrasonography of abdomen, *Colonoscopy All these investigations should be within normal limits for one to say you have IBS. Treatment: STRESS = stress is the most important cause of IBS. Please remember and you must have observed that when you do not have stress your problem with IBS is reduced Change of lifestyle. I think may be you are not coping with something. Vacation outside of your area, mobiles phones to be off. You must have noticed already that these changes help a lot. Try to avoid anything which you are / have to do against your will and wish. Getr into the hobbies which make you forget the world around you. Life comes only once, boss.
