- CT Scan
An endoscopy can help determine if there is blood in the stomach. Patients are sedated during this test. Your doctor inserts a small, flexible tube (endoscope) into your mouth. This tube goes all the way down to your small intestine and stomach.
The tube has a fibre-optic camera. This can further help doctors evaluate if there is an internal source of bleeding.
Your doctor may also ask you to get a blood test to check your total blood count. This can further help determine the volume of blood lost. In some cases, a biopsy may be required to understand if the source of bleeding is cancerous, infectious, or inflammatory. Based on this information, your doctor will suggest the most appropriate treatment for your condition.
