My dad is 61 years old, weighing 92 kilos now. He had renal and gall stones 17 years back, got it operated to remove the kidney stone and had to remove the gall bladder itself. After that operation he is gaining weight gradually and his tummy is really big now. He is finding it difficult with his day to day activities. Please suggest if we could go for Liposuction to reduce the size of his tummy.
