What does persistent indigestion feel like with stomach cancer?

The sensation can linger after meals or return repeatedly rather than settling as expected. Some people notice pressure, bloating, belching, reduced appetite, or feeling full after eating only a small amount. Nausea, vomiting, or discomfort high in the abdomen can occur alongside it. These features are not specific to cancer; reflux, ulcers, medicines and other digestive conditions can cause similar symptoms. Persistent indigestion needs assessment because the pattern, examination and investigations together provide the explanation.

Arrange a medical appointment if indigestion keeps returning, changes from your usual pattern, or comes with reduced appetite, unplanned weight loss, vomiting, trouble swallowing, or dark stools. Keep a brief record of meals, timing, pain, nausea, bowel changes and medicines. A clinician may review your history, examine your abdomen and decide whether blood tests, imaging or an upper gastrointestinal examination are appropriate. Do not stop prescribed medicines without advice.

Seek urgent help for vomiting blood, black tar-like stools, severe or rapidly worsening abdominal pain, fainting, confusion, or inability to keep fluids down. Contact a clinician promptly for ongoing vomiting, new swallowing difficulty, or marked weakness. The urgency comes from these warning signs and their possible effects, not from indigestion alone.

Ask what could be causing the symptoms, which warning signs should prompt urgent help, whether your medicines or reflux history matter, and which tests would clarify the cause. Ask how to maintain food and fluid intake while you wait for assessment.
