Accepted Answer

Melena: Black tarry stool, otherwise known as melena, can sometimes be due to diverticulitis, but certainly can be a sign of bleeding in the upper digestive tract. You should share this new finding with your doctor and see if it affects her working differential. You may need tests to rule out an upper gastrointestinal source of bleeding. Good luck.

Question 3

i have blood in stool. i've had 4 colonoscopy. negative results. had diverticulitis before. what could my problem be?

Accepted Answer

Maybe not colonic...: Evaluation is always appropriate for re-bleeding from the gut. Black stool often means bleeding from upper GI tract; grape jelly stool from small bowel; silver stool from biliary tree; burgundy stool from right colon; red blood from left colon to anal canal. Any accompanying symptoms? Do you take NSAID's, over-use alcohol, smoke tobacco, have other risks (AVM's for example)--lots to consider.

Question 4

gas, bloating, bad stomach pains that radiate to back, bright red blood in stool sometimes normal ultrasound. what can it be? gastitis? diverticulitis

Accepted Answer

Unlikely gastritis: Bright red blood is usually associated with disease of the left colon such as diverticulitis or hemorrhoids, but the latter is not typically associated with gas bloating. See your internist for an evaluation.

Wish you good health!
Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually.

Practice safe sex, if you have sex.
