Tamoxifen and weight gain

has anyone else had trouble keeping weight off taking tamoxifen? I have been taking 9 months and putting on weight,sometimes I'm just starving probably hormones I suppose,I'm quite active bike ride,gym ,walking and try to eat well most time,I wondered if it's because I'm premenopausal in early 40s? Anyone lost weight on tamoxifen?

    Hi @Milly21
    I was on Tamoxifen for 2 years before having my ovaries removed and swapping to an AI. I was 47 and in chemo induced menopause when I started. I did manage to lose 9kg and maintain that during that time. I was very careful with what I ate (changed a lot of things and ate smaller portions) and walked and swam a lot. I found keeping a diary of what I ate and also the exercise that I did each day helped. 
    I have recently put on a couple of kilos due to increased snacking (even though they are healthy snacks it is just too much) and less exercise. The diary is in use again! I am determined to get back to the weight I feel best at. Lots of walking and I need to get back in the pool too! It can be done  :)

    Hi @Milly21, had lost a little bit but I started working out at the gym and sports physio told me to eat protein before and after weight sessions. So I worked out and my mouth worked out harder with protein, sweet biscuits, etc etc etc... :(
    Put on 3 kilos. So am back to being more sensible and have been working out a couple of times a week with a work colleague but need to hit the gym again. Like @Deanne I'm determined to lose again for when I have my reduction surgery on my remaining breast around June next year. I do recognise the fact that I have now been pushed into menopause but just need to work a bit smarter than I have been. Let us know how you get on with your weight loss. All the best. Xx Cath

    Thanks for the suggestions I have started a food diary,that was a good idea as it really shows what your eating,tried to cut out snacks,I think before taking tamoxifen I didn't really have to try to maintain my weight,just exercising and now I am going to have to watch how I eat as I can't eat like before,my meals are healthy but I think my portions size are to much.thanks ladies

    Try swapping brands. I was ok on Novladex D. Then I went on to Sandoz and while i had less bone aches on it, I really packed the weight on at about a kilo a week. I have just gone back to the Novladex and now I have to walk all the extra padding off. Before Sandoz I could easily get it off walking but while on Sandoz it would not lower at all and just kept going on.

    It's an interesting one, I was on tamoxifen for 4yrs pre menopause at 43-47 years of age before I had a recurrence. I didn't have any issues with weight gain or side effects that were super noticeable. However at my recurrence at 47, Chemo threw me into an unnatural menopause and then went onto Arimidex, whoa! heaps of side effects so a year later I was switched to Aromasin...hmmm yeah no different, Ive just learnt to live with it I think. Though...I put on weight through treatment like 7kg and 2yrs on cannot shift it through diet or exercise. So I'm wondering now the weight is a combination of things, its firstly chemo related for me, menopause and then Aromasin, all together make it near impossible. I admit its something that really annoys me.. Melinda xo

    I am on sandoz,maybe I should try the other one too,as not much I do has helped shift the weight.

    I was on the Sandoz too, I think they all have the side effect of weight, I have just found in my 40's as you say, everything changes, I cant eat the way I used to and I didnt need to manage my weight at all. Now whoa!!! its ridiculous, so I too am really being conscious with snacks but not alot has made any difference, very frustrating. All the best, try alot of different things, change up maybe your exercise? I ride an exercise bike and have now started doing 30sec bursts really fast every 2 mins. I walk too but cannot manage major exercise anymore, I have fibromyalgia and treatment exacerbated it big time so exercise unfortunately doesnt make it better, bit of a vicious circle lol, but I keep on trying anyway. x M
