My dad has diabetes 2. He also had a stroke nearly 2 years ago which left him paralysed down the right side. He manages to walk very short distances but obviously spends a lot of his time sitting. He has now got problems with poor circulation in that side. He is having tests but Is there anything meanwhile he can do to help improve circulation? He has a very sweet tooth and loves his cakes which my mum limits but probably not enough as he has a difficult enough life and this is one of his few pleasures.
