Ive been getting pains in my abdomen, a feeling of nausea and my syools are very dark, almost black.  It hurts in my abdomen when I open my bowels.  I had a total abdominal hysterectomy six years ago and I have diverticular.  My tum area is always swollen since my op and I put on 2 stone after that I dont seem to be able to lose even though I eat a very healthy diet
Welcome to Chat Doctor .1. Black stools generally indicate presence of old blood (from higher level).2. Get a stool examination for presence of blood in the stool.3. Try to change have healthy diet like salts, fruits, avoid junk food and see for 2 weeks.4. If there is no change in stools, then I would recommend you to get a CT scan done, which will evaluate your post-operative site and any infection / inflammation in the operative site. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
