Diverticular disease is a top reason for lower GI bleeding. Other causes include ulcerative colitis, which leads to swollen areas and sores in the colon and rectum.

Addressing the Underlying Cause

Doctors will suggest different gastrointestinal bleeding treatments to stop stomach bleeding. If it’s in the upper GI tract, they might give you drugs like proton pump inhibitors (PPIs) to cut down on stomach acid and help it heal. If it’s because of bowel diseases like Crohn’s or ulcerative colitis, they’ll use medicines to calm down inflammation. And sometimes surgery is needed to help, like getting rid of hemorrhoids or polyps.

Supportive Care

Getting extra help is needed alongside dealing with the root cause of the stomach bleeding. This includes giving fluids through a vein, blood transfusions, and meds to stop the bleeding. In hard cases, they might use a special scope to look into the gut and stop the bleeding there.

Your healthcare team and you will put together a special plan to treat your stomach bleeding. This plan will deal with the cause and give the needed care to get you stable and avoid more problems.
