nancy, I gained 25 pounds after starting on Tamoxifen and I've been dieting all summer, but so far have only been able to knock off about 10 pounds of it. Exercise is the right approach, but I was so tired and spacey that I had to tackle my diet first to get my energy back. I bought a juicer and now drink fresh juice once or twice a day. It does help a lot with my appetite and energy.

I did gain weight and yes I did stop my menstrual with hot flashes. My oncologist said at my age(43), that I may start my menstrual cycle back or could go into early menopause. As far as the weight, I have lost that. :}

I gained about 15lb after I started Tamoxifen. Because I had hysterectomy 16 years ago, I have not way for my body to produce estrogen. My gynocologist said the spare tire around my waist was my body trying to produce estrogen. I guess estrogen loves belly fat.

I gained about 30 pounds on Tamoxifen, but I was on it for 8-1/2 years. It was extremely difficult to lose the weight but walking and low carbs helped tremendously.

chemotherapy made me go through menopause.
