Does anastrozole cause weight gain? It's a really common concern, and the short answer is: it can, but it varies from person to person.

Some studies suggest weight gain from anastrozole is small or may not happen at all. However, many people do notice changes in their weight, especially in the first year of treatment. Certain factors may make weight gain more likely, including:

- Being younger than 60
- Having had a mastectomy
- Smoking cigarettes

A MyBCTeam member shared, "I exercise moderately six days a week and have gained 10 pounds since I started taking this drug. I feel like I'm pushing a door against hurricane winds." Another MyBCTeam member said, "Well, I sure have been successful gaining weight on anastrozole... to the tune of about 35 pounds!"

So you're definitely not alone in this experience. Here are some tips that may help manage weight while on anastrozole:

- Track your food intake — a photo diary or notebook can help spot patterns
- Limit alcohol — it adds calories without nutritional benefit
- Work with a registered dietitian — personalized guidance can make a real difference
- Talk to your oncology team — they can help identify causes and suggest solutions

Always check with your doctor before starting any weight management plan, as they know your full health picture best.
