Gastritis occurs when your stomach lining becomes inflamed (swollen and red). It can last for a short time then go away, or it can last a long time.
Gastritis has several causes, including infection. Treatment of will depend on the cause.
You can ease the symptoms of gastritis by eating and drinking in ways that don’t annoy your stomach, and by medications.
To treat your stomach gently:
- avoid alcohol
- avoid foods that give you pain
- eat smaller meals
- avoid using non-steroidal anti-inflammatory drugs, or NSAIDS.
Medicines may be used to:
- reduce the production of stomach acid
- make the stomach less acidic
- treat an infection with Helicobacter pylori, or H. pylori, which is a common cause of gastritis.
Types of gastritis medicines
Gastritis is often caused by an infection. It can be treated with antibiotics. If your doctor prescribes antibiotics, you need to finish the whole course to make sure you get rid of the infection.
H2 blockers are medicines that reduce the amount of acid in your stomach. They include ranitidine and famotidine.
Proton pump inhibitors
Proton pump inhibitors are like H2 blockers, but stronger. They include omeprazole and pantoprazole.
Antacids work by neutralising stomach acid.
Important information about gastritis medication
If you have gastritis, discuss with your doctor:
- the benefits of medicine for gastritis
- the risks of medicine.
See your doctor if you vomit blood or notice blood in your stool (your toilet) as these may be signs of stomach bleeding.
