how do i know if i have a stomach ulcer

The main signs that you may have a stomach ulcer include burning or dull pain in the upper abdomen, typically between the belly button and breastbone. The pain may come and go and can occur when the stomach is empty or at night. Other symptoms include feeling full too soon during a meal, nausea, vomiting, bloating, belching, loss of appetite, weight loss, and in severe cases, vomiting blood or having black, tarry stools. Some people experience worsening abdominal pain or sharp, severe pain, which may indicate complications requiring immediate medical attention. If these symptoms are present, seeing a healthcare provider for diagnosis and treatment is important since ulcers are often caused by Helicobacter pylori bacterial infection or long-term use of NSAIDs (nonsteroidal anti-inflammatory drugs).
