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.

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