Weight gain / bloating

I’ve been on tamoxifen for four years coming up this Christmas. I responded very well to all my treatment but in the past year I have gained a lot of weight. I am petite so been very very lucky with weight . I do weights at home along with walking and yoga but it’s getting worse. I have got rid of lots of clothes and find it’s the middle area . My stomach becomes bloated and easily looks very odd on my small frame.  I eat well and don’t eat processed foods lots of chocolate or meat. I mostly cook vegan vegetarian and make sure I get in protein with nuts and beans but still i feel awful with this. 
my cancer was estrogen and I am concerned now I am fat and this is not good or healthy for me. I have tolerated tamoxifen very well and had not other side effect apart from 20 flushes every day but acupuncture helped a lot. I have only about 5 now which is fine . No aches or pains and if there was I just ran a little longer. However to see my body like this is just difficult. I also have treading on my chin which has become worse recently too. I don’t know if I should ask my cancer centre if it’s thyroid , tamoxifen crash menopause? There must be something I can do. Has anyone else had this or can recommend anything ? I fully understand I will be in the menopause for life but  how much weight will this mean . I am due to be on tamoxifen for ten years . Do I change it ? Do I ask for weight loss help and if so I am not sure there is too much I can change if I am honest .  I have always taken the same brand of tamoxifen, so has anyone experienced this with different brands being used or different hormone blockers used ? 

Thank you and sorry for any errors I am dyslexic xx

  • Hi MK girl

    I was only on tamoxifen for a year before being switched to letrozole as now post-menopausal.  I follow the same diet as you, very healthy, just fish and plant based and I too am finding the weight is creeping on.  I've upped my exercise, but was already doing a lot, and am now thinking very carefully about my carbs intake.  It's the last thing I can try and being heavier really gets me down.  Sorry you're having such a tough time.  It's hard enough to navigate mentally without the physical delights it throws our way!  It sounds like you're doing everything right but always worth an ask with your breast care nurse etc.  I can't offer any solutions but I totally understand x

  • Thank you for your reply. I went form peri to post a. D was told by macmillion I should no be on tamoxifen as I am now post . I’ve asked my doctor to call me and also my cancer centre so I can discuss this because otherwise they said 10 years on tamoxifen and I’ve been left but the first couple of years I was ok but it’s now it’s hitting. I have looked at three of the blockers on breast cancer now and I don’t know which would be best.  They all seem there are three letrozole, a astro olé and exemestane. I imagine they are all similar side effect and I could get even bigger but I guess I could see how I get on and in the mean time fast , keep doing weights and pilates. It’s all difficult and my main worry is I can’t get into dresses but the effect that is having on my health. Being overweight is not good and it gets me down with this huge stomach and then another time it’s better. I just don’t understand. 

  • Yes it's so difficult.  I haven't found I've gained more weight on the letrozole, but I certainly haven't lost either.  As you say, maybe you could ask about one of the hormone blockers if you are post-menopausal.  I had to push to get my bloods tested, otherwise I think they would have been happy to let me carry on with tamoxifen x

  • Hi  , I’m a lot older than you as there were no doubts about my menopausal status at my diagnosis (I was 59 and had menopause at 50). I’m on Anastrozole and I’ve definitely found I’ve grown a tummy over the years (I’m on year 6 of pill popping, due to stop at 7). When I was initially diagnosed I lost over half a stone which is quite normal for me in times of stress. I wasn’t overweight to begin with so the loss of weight was quite noticeable. Over my years on Anastrozole I’ve gradually gained about half of it back again, even though I do plenty of exercise, more than pre diagnosis and I’m definitely fitter. I eat a diet like yours.  I am sort of resigned to the bigger tummy as it doesn’t seem to change. To my mind I sometimes look like I’m pregnant! But friends think I’m ridiculous as they’re mostly bigger than me anyway. But I know what my shape was and it’s definitely changed! 
    That’s not really much help in your current dilemma but you’re definitely not alone. I’ve read others here mention both weight gain and larger midriffs! Do speak to the doctors about trying another hormone treatment as I think it’s not uncommon nowadays to have a combination of however many years on tamoxifen followed by further years on an arometase inhibitor like anastrozole or letrozole. Love and hugs, HFxx
