What does persistent abdominal pain feel like with neuroendocrine tumours?

The discomfort may be felt in the upper or lower abdomen, depending on where a tumour is located and which nearby structures are affected. Some people describe pressure, bloating, spasms, or pain that comes in waves; others notice a persistent ache. Changes in bowel movements, nausea, reduced appetite, or early fullness can occur alongside abdominal discomfort. Symptoms vary and do not establish a diagnosis by themselves.

Neuroendocrine tumours can arise in several organs and may release hormones in some cases. That means the symptom pattern can differ widely. A healthcare professional uses your history, examination, and appropriate investigations to work out what is happening.

Keep a short record of pain location, sensation, timing, bowel changes, meals, and medicines. Make an appointment if the pain persists or disrupts normal activities. Tell the clinician about flushing, diarrhoea, wheezing, unexplained weight change, or episodes of a racing heartbeat if they occur, because these details may help guide assessment. Do not stop prescribed treatment without advice.

Get urgent help for intense or escalating pain, persistent vomiting, inability to pass stool or gas, a very swollen abdomen, collapse, severe weakness, breathing difficulty, or blood in vomit or stool. If you have a known neuroendocrine tumour and develop sudden flushing with breathing or heart symptoms, seek urgent medical attention.

Ask where your pain may be coming from, whether hormone-related symptoms are relevant, what examinations or scans may help, and how to manage nausea, bowel changes, or pain. Ask for clear instructions about which symptom changes require same-day help.
