I am suffering from probably IBS ,since last eight years I was having more of watery ,diarrhea like stools sometimes they were normal, sometimes constipation. It was having effect on my weight also. Now finally I was operated for hemorrhoidectomy. Now I have been advised for fibre rich foods. 6 to 8 glasses of water. Some painkillers and antibiotics with suksarak as laxative. I was already following a vegetarian diet I don t have any addictions and don t eat non veg food, meat fish, eggs, poultry. After operation though I am following the directions, diet, I am still having constipation and burning sensation after evacuations. And the contraction of the muscle,inflamed vein takes time.is it because of stress .kindly advise.
