Hi my husband is on immunotherapy and just had his 3rd he is doing really well now but after the 1st one he lost a stone and a half in 3 weeks wouldn't eat knew he had to drink but he was only drinking water,tried those fortisips drinks no wouldn't drink them, got in touch with his immunotherapy department and they spoke to the consultant and they gave him steroid tablets 2nd day after taking them he started eating and hasn't stopped since, has put the weight back on and is feeling  a lot better, so please phone the number on the immunotherapy card and talk to them, hope your Mum will feel a bit better soon. 

Hi, 

Mum is diabetic that makes it complicated with steroids I think .

O sorry, my husband isn't diabetic but please ask the immunotherapy department for help, my husband treatment had to be delayed by a week as he wasn't strong enough to have the second treatment, he is now had his 3rd and doing ok, I do hope your Mum will feel like eating soon even if its small amount but often, take care.
