Hi i have upper left mild abdominal pain, since a month. It comes and goes. Doctors identified it as gastritis. Today i had a two toned stool- greenish on the outside and light black in the middle. what could this be?  I have no history of cancer and am 27 years old
Hi, Welcome to Chat Doctor. I have read your query and understand your concern. Its gastritis only, and at your age we usually don't think of cancer. The color of stool depends to a great extent on what you have eaten in the past 2-3 days. And if you have not eaten anything like that, then your stool might be suggestive of a mild upper GI tract bleeding, though it is not classical of it with this color. So, I would suggest, that you take a course of a PPI tablet like pantoprazole or omeprazole for a month to allow all the ulcers in your stomach to heal completely. Also, you need to avoid tea, coffee, soda Chat Doctor. Hope I have been helpful.
