How acid reflux affects the oesophagus

The oesophagus carries food from the mouth to the stomach. Unlike the stomach, its lining is not designed for repeated contact with acidic digestive contents.

Repeated exposure may inflame the oesophagus, a problem called oesophagitis. This can cause pain behind the breastbone, discomfort with swallowing, or the sensation that food is slow to pass. Reflux may also reach the throat and contribute to hoarseness or cough.

Not everyone feels classic heartburn, and symptom intensity does not show how irritated the lining is. Persistent or changing symptoms sometimes require examination or a camera test so a clinician can look for inflammation, narrowing, or another explanation.

Leave a gap between the evening meal and lying down, choose smaller portions, and stay upright after food. Identify personal triggers rather than removing many foods without a clear pattern. If symptoms occur in bed, raising the head end can reduce upward flow more effectively than stacking pillows.

Medicines that neutralise acid, form a protective raft, or reduce acid production serve different purposes. A pharmacist or doctor can match an option to symptom frequency and check for interactions, pregnancy considerations, or conditions that change what is suitable.

Get urgent medical help if chest discomfort is severe, feels like pressure, follows exertion, or occurs with shortness of breath, sweating, faintness, or pain spreading beyond the chest. Heart and lung problems can resemble reflux.

Book a prompt assessment if swallowing becomes difficult or painful, food sticks, vomiting persists, vomit contains blood, stools look black, or weight drops without trying. A new persistent symptom also warrants review, especially if treatment no longer controls it.

Describe where discomfort sits, whether liquids or solids catch, what reaches your mouth, and whether symptoms wake you. Ask if you need a treatment trial, testing for another cause, or an endoscopy, and clarify when the response should be checked.
