Foods to avoid for a peptic ulcer

Updated April 17, 2017

In the past, doctors have recommended that people with peptic ulcers restrict their diets. That's not necessarily the case any more, but experts at the National Institutes of Health (NIH) say there are some foods you might need to limit.


According to the Mayo Clinic, peptic ulcers are sores in the lining of the stomach, oesophagus or small intestine. If untreated, they can cause internal bleeding. The Mayo Clinic says doctors used to think that food and stress were factors in causing peptic ulcers. But now, the clinic says, doctors know the ulcers are caused by a bacterial infection or medication.


The NIH says people with peptic ulcers used to be told to drink a lot of milk. But that is no longer the case.


According to the NIH, tests are still being done to determine whether pepper is good or bad for peptic ulcers. In the meantime, the NIH recommends if you have a peptic ulcer, you should avoid any spices that cause discomfort.

Caffeine and Alcohol

The NIH says current studies recommend that people with peptic ulcers avoid alcohol and restrict coffee and other beverages that contain caffeine.


The NIH says if you have a peptic ulcer, there is nothing that indicated you should avoid fibre. In fact, the institute says some foods with fibre may help prevent ulcers.


The NIH and Mayo Clinic say you should not overeat if you have peptic ulcers, and you should not drastically alter your diet. Before making any changes, consult your doctor.
