Weight Gain, No loss - Due to Tamoxifen?

[jaykay]

I gained weight with tamoxifen - about 5 lbs - and I worked out pretty much every day and watched my diet. Also had serious fluid retention and had to take a diuretic every other day.

I lost the 5 lbs within 1 month of completing tamoxifen. Don't take the menopause factor lightly. I was post-menopausal pre BC and was fighting the weight battle then. My doctor told me that every 10 years your metabolism slows down and I either had to work out more or eat less. Unfortunately, she had been proven right every 10 years

There is also an additional, hidden culprit in standard treatment (i.e., chemotherapy) that affects the ability to lose weight. Steriods are given as support drugs for the chemo. The affect of steroids on the body is to decrease muscle mass, and decreasing muscle mass equates to burning fewer calories when you move around, which results in weight gain over time.
