Hi, I have been taking Tamoxifen for 3 years. I put on a lot of weight after being on Tamoxifen for 2 years, I wouldn't say that Tamoxifen caused this. I was also told it would be harder to lose weight while taking Tamoxifen but in the last 24 weeks I have lost 20.5 kg and have 5.2 kg to go and this will put me into the normal weight range for my height ( I cannot ever remember being this weight). I have been using Weight Watchers and the only exercise I have been doing is walking.
In the last week I have also found out I am one of the unlucky ones to have a large polyp(not cancerous) and hyperplasia a result of the Tamoxifen, so now recovering from that surgery then back to gyno so see what the next step is.
Don't give up, you can do it just take and accept little steps.
Regards Michelle
