Weight Gain

Weight gain is a common side effect for patients who have received:

  • Chemotherapy
  • Endocrine suppression therapy with tamoxifen, anastrazole, letrozole, or exemestane

It is potentiated by other side effects of treatment such as arthralgia and hot flashes.
Other causes of weight gain (e.g. depression and thyroid dysfunction) should be ruled out.


  • Calorie restricted diet
  • Regular cardiovascular exercise, preferably weight bearing
  • Refer the patient for dietary counselling
  • Refer to local exercise and fitness programs aimed at breast cancer survivors
