I have also gained weight (also about 10 pounds) whilst on chemo - another's SE to add to all the others! Well, if it is a SE or me just over-eating!! I am 48 hours post FEC 4, with two more rounds of FEC 75 chemo, followed by Herception.
Before starting chemo, I heard that you could either lose weight - or gain it. I hoped to lose weight - not so!
i am eating healthily, have not lost my appetite though, if anything, I seem to be eating a bit more, maybe the steroids? Admittedly, I have not been doing as much exercise, I used to go on long walks regularly and swim before treatment started, but now my energy levels so low, I haven't got the energy to walk so far - and swimming is a no-no while on chemo, according to my BCN, incase of infection.
I too would be interested if anyone knows if weight gain whilst on chemo/Herceptim can be down to the chemo drugs or down to being less aactive and more duvet days etc. I think it may be combination of both, but if anyone on this forum has spoken to their ONC or BCN about weight gain and the cause whilst on chemo/Herceptim, can you enlighten us fatties please?
