Can stress cause indigestion?

During worry or tension, the body shifts attention toward immediate demands. This can alter stomach movement, appetite and the sensitivity of digestive nerves. Some people notice burning, bloating, belching, nausea or early fullness during stressful periods. Stress may also change eating speed, meal size, sleep and use of caffeine, alcohol or painkillers, each of which can aggravate symptoms. Acid reflux, gastritis, gallstones, a hiatus hernia, Helicobacter pylori infection or a peptic ulcer can cause similar complaints, so a stress connection does not prove stress is the only cause.

Keep a simple diary of symptoms, meals, sleep and stressful events. A repeated pattern is useful, but symptoms that continue when life feels calmer still deserve medical attention.

Eat slowly and choose smaller regular meals. Remain upright after eating, protect your sleep routine and reduce any trigger you can identify. Gentle walking and slow breathing may reduce tension and help you notice whether you are swallowing air. Do not stop prescribed medicines without advice. A pharmacist can discuss suitable short-term indigestion relief, while a clinician can assess persistent symptoms and discuss support for anxiety, sleep or ongoing stress.

Seek urgent help for vomiting blood, black stools, severe abdominal pain, fainting, chest pressure, sweating or breathlessness. Arrange a medical review for symptoms that persist, recur frequently, wake you at night, cause difficulty swallowing or come with unintentional weight loss. Stress can contribute to indigestion, but it should not be used to explain away new or severe symptoms without an assessment.

Could reflux, gastritis or a medicine be contributing? What can I safely use during a flare? How should I track stress and digestive symptoms, and when should I return?
