Breast Cancer Weight Gain
Weight gain may occur when a patient undergoes breast cancer treatments. In addition, lifestyle factors during treatment may also contribute to weight gain.
Studies indicate that some patients undergoing breast cancer treatment will become overweight. The weight gain may be sustained even when treatment has ended. For some patients, they may lose muscle and increase fat tissue. The usual methods of weight loss like diet and exercise may not work for them. One reason for weight gain is the use of corticosteroids, which increase appetite. Corticosteroids are hormones that can also cause an increase in fatty tissue. Women treated with steroids can also gain weight after several weeks of continuous use.
Treating cancer with hormone therapy may be another cause of weight gain. This treatment reduces the amount of estrogen and progesterone in women and testosterone in men. When the levels of these hormones are reduced, this tends to increase the amount of body fat, reduce muscle mass, and cause a change in the way the body converts food into energy.
