What should I do if my weight changes?
ACS Answer
Weight changes during treatment for cancer are common. Causes of weight loss include:
- Poor appetite
- Eating less
- Diarrhea
- Vomiting
- Nausea
- Dehydration
Causes of weight gain include:
- Less activity
- Eating more
- Retaining water
- Certain drugs
You should report weight changes greater than 5 pounds in 1 week to your doctor. A decrease in weight over time may affect your ability to function, leaving you feeling weak and unable to participate in daily activities. An increase in weight over time may suggest a serious health condition, such as diabetes or high blood pressure. You may be able to tell if you gain or lose 5 pounds in a week just by the way you feel, or you can weigh yourself on a scale once a week.

- Increase in weight of 5 pounds or more in 1 week
