A hiatus hernia is a problem affecting the stomach. It can cause stomach acid to travel up to your throat.
Symptoms of hiatus hernia include a burning feeling in your chest (heartburn), burping and feeling sick.
Treatments for a hiatus hernia include taking antacids, eating smaller portions and losing weight. You may need surgery if it does not get better.
It's not clear what causes a hiatus hernia. It's more common if you're over 50, pregnant or overweight.
