Clair, in an internet search for bisoprolol weight gain, I found this medline page.
It lists "unusual weight gain" as a serious side effect and states you should call your doctor immediately.

Thanks rockrose, i had a look at the link. Only problem is ive only got the months course but will always have the heart issue meaning theres no point in contacting my doctor as i wont always be on the medication, ive stopped takin them tho. The weight is really loose so hopefully i can lose it!
