Why am I gaining weight on anastrozole?
Community Member
a day agoI’m a cancer survivor of stage 2 Hers2 positive and after my chemo and 11 Herceptin I was put on 1mg of anastrozole which will be 2 yrs Aug 22 and I was wondering if anyone gained weight on it. I have gained like 30 lbs and it’s been hard to lose. I was put on Zoloft as well and I have to take thyroid meds for hypo so I thought maybe it was the Zoloft so I weaned off that a month ago but it’s a struggle to lose a lb or two.

20 hours agoWeight changes during cancer treatment and recovery are incredibly common, and many people in this community have experienced similar challenges. The combination of hormonal treatments and other medications can affect metabolism and make weight management more difficult than it was before treatment. It's encouraging that you're being thoughtful about identifying potential causes and working with your care team - discussing these concerns with your oncologist can help you understand what to expect and explore strategies that work best for your situation.
