Medicines for Hiatus hernia
A condition in which part of the stomach slides up through the diaphragm into the chest — often causing no symptoms, but commonly bringing on acid reflux and heartburn that is managed in the same way as reflux.

Quick answer
What is Hiatus hernia?
A hiatus hernia happens when part of the stomach pushes up through the hiatus — the small opening in the diaphragm where the gullet (oesophagus) normally passes from the chest into the abdomen. It is very common, especially with increasing age, and many people who have one never know, because it causes no symptoms at all.
- How it is treated: Because the troublesome symptoms of a hiatus hernia are those of acid reflux, treatment follows the same approach as managing reflux rather than treating the hernia itself.
- Self-care: Reaching and keeping a healthy weight takes pressure off the stomach and can markedly reduce reflux.
- When to seek help: See a GP if reflux symptoms are frequent, persistent or not controlled by simple measures and over-the-counter remedies, so the cause can be assessed and treatment reviewed.
What it is
A hiatus hernia happens when part of the stomach pushes up through the hiatus — the small opening in the diaphragm where the gullet (oesophagus) normally passes from the chest into the abdomen. It is very common, especially with increasing age, and many people who have one never know, because it causes no symptoms at all. When symptoms do occur, they are usually those of acid reflux: heartburn (a burning feeling behind the breastbone), an acid or sour taste at the back of the throat, and discomfort that is often worse after meals, when bending over or when lying down. This is because the hernia can weaken the natural barrier that normally keeps stomach acid from rising into the gullet. Most hiatus hernias are the "sliding" type and are managed in the same way as ordinary reflux. A small number are large or of a different type and may need closer assessment.
How it is treated
Because the troublesome symptoms of a hiatus hernia are those of acid reflux, treatment follows the same approach as managing reflux rather than treating the hernia itself. Simple measures come first: losing weight if needed, eating smaller meals, not lying down soon after eating, and raising the head of the bed so gravity helps keep acid down overnight. Where symptoms persist, medicines that neutralise or reduce stomach acid are used — antacids and alginates for quick, on-the-spot relief, and acid-suppressing medicines to settle symptoms more fully and allow the gullet lining to heal. Surgery to repair the hernia is reserved for the minority of people with large hernias or severe symptoms that do not respond to other measures, or where there are complications. Most people are managed well without an operation.

Symptoms that can point to Hiatus hernia
Hiatus hernia can be one cause of these symptoms. Each guide explains the other possible causes and the red-flag warning signs that mean you should get urgent help:
Beyond medication
Lifestyle and self-care
Reaching and keeping a healthy weight takes pressure off the stomach and can markedly reduce reflux. Eating smaller, more frequent meals rather than large ones, and avoiding eating in the few hours before bed, helps — as does not lying down straight after eating. Raising the head end of the bed by a few inches uses gravity to keep acid down overnight. Cutting back on things that trigger reflux, such as rich or fatty foods, caffeine, alcohol and smoking, often helps too. Loose clothing around the waist can ease pressure on the stomach.
When to get help
When to see a doctor
See a GP if reflux symptoms are frequent, persistent or not controlled by simple measures and over-the-counter remedies, so the cause can be assessed and treatment reviewed. Some symptoms need more urgent assessment: difficulty or pain when swallowing, food sticking, unintentional weight loss, persistent vomiting, or vomiting blood or passing black, tarry stools should be checked promptly, as these can point to a more serious problem rather than simple reflux.
Not sure how urgent it is? It is always OK to call NHS 111 for advice, day or night.
Answers
Hiatus hernia: frequently asked questions
What medicines are used for hiatus hernia?
There is no medicine that removes a hiatus hernia, so treatment is aimed at the reflux symptoms it can cause. Antacids and alginates give fast, as-needed relief by neutralising acid and forming a protective raft over the stomach contents. Where symptoms persist, acid-suppressing medicines are used: proton pump inhibitors (PPIs) reduce acid strongly and help the gullet lining heal, and H2-receptor antagonists are an alternative or add-on. Simple measures such as weight loss, smaller meals, not lying down after eating and raising the head of the bed are used alongside.
Does a hiatus hernia need surgery?
Most hiatus hernias do not need surgery and are managed well with lifestyle measures and medicines for any reflux. An operation to repair the hernia is reserved for a minority — typically those with a large hernia, severe symptoms that do not respond to other treatment, or complications. If symptoms are not controlled despite treatment, a GP can arrange assessment to discuss whether surgery might help.
Can a hiatus hernia cause no symptoms?
Yes. Many people have a hiatus hernia and never know, because it causes no symptoms at all and is sometimes found by chance during tests for something else. When symptoms do occur they are usually those of acid reflux — heartburn, an acid taste and discomfort after meals or when lying down. A symptomless hiatus hernia found incidentally usually needs no specific treatment.
What lifestyle changes help a hiatus hernia?
The same measures that help reflux help a hiatus hernia: losing weight if you are overweight, eating smaller meals, not lying down soon after eating, and raising the head of the bed so gravity keeps acid down overnight. Cutting back on triggers such as fatty foods, caffeine, alcohol and smoking, and avoiding tight clothing around the waist, can also reduce symptoms.
