Eating Problems

A person with a poor appetite or no appetite may eat much less than normal or may not eat at all. A poor appetite can be caused by a changed sense of taste or smell, feeling full, tumor growth, dehydration, or the side effects of treatment. 

Weight changes during cancer treatment are common. Some side effects might lead to weight loss, while others might cause a person with cancer to gain weight. 

A person may gag, cough, spit, feel pain, or have other problems when trying to swallow. There can be a number of causes. It may be a short-term side effect of chemo or radiation treatment to the throat or chest. It may also be caused by an infection of the mouth or esophagus, as well as other problems.

Cancer and its treatments can change your senses of taste and smell. These changes can affect your appetite and are often described as a bitter or metallic taste. Food can also taste too salty or sweet. 

Learn about nausea and vomiting -- what causes it, how it can be prevented or treated, and what questions you should ask your health care team.

Common side effects such as dry mouth, sores in the mouth, or bleeding can cause eating problems for people with cancer.

Nutrition is an important part of cancer treatment. Eating the right kinds of foods during and after treatment can help you feel better and stay stronger. Learn more about the importance of good nutrition during and after cancer treatment here.
