Weight changes during breast cancer treatment can vary from person to person. While anastrozole and other aromatase inhibitors are more commonly associated with weight gain rather than weight loss, each person's body responds differently to treatment.

Several MyBCTeam members have reported different experiences with weight changes while taking anastrozole. Some have gained weight, while others have struggled with maintaining their weight. If you're experiencing unexpected weight loss, it's important to discuss this with your oncology team. They can:
- Run tests to determine the underlying cause
- Help develop an appropriate nutrition plan
- Adjust your treatment if necessary
- Connect you with a dietitian for personalized guidance

Weight changes can impact your overall health and treatment effectiveness, so it's essential to keep your healthcare providers informed about any significant changes in your weight.
