Can acid reflux be prevented?

Reflux occurs when stomach contents move upwards into the oesophagus, causing burning, sour fluid, or irritation. It may be more troublesome after large meals, when lying down soon after eating, or when particular foods and drinks relax the valve between the stomach and oesophagus.

A hiatus hernia can contribute by changing the position of the stomach and valve. Higher body weight can also increase pressure around the stomach; obesity is one condition that may be relevant to an individual assessment. Not every trigger affects every person.

Try smaller meals, avoid lying down soon after eating, and raise the head end of the bed if night symptoms occur. Keep a brief record of meals, medicines and symptoms so you can identify personal triggers. Common triggers include alcohol, smoking, fatty meals, spicy foods, coffee and late-night eating, but change only what clearly affects you.

A clinician or pharmacist can advise about antacids, alginates or acid-lowering medicine. Long-term symptoms deserve review rather than repeated self-treatment, especially if you need frequent relief.

Book an appointment for frequent reflux, symptoms that disturb sleep, or difficulty swallowing. Seek urgent help for chest pressure with sweating or breathlessness, vomiting blood, black stools, or sudden severe pain.

Which changes match my symptoms, and could a hiatus hernia or another condition be contributing? Do I need a treatment review or tests for persistent reflux?
