I have a special family member who recently had their stomach removed due to cancer. He is battling to put on weight after the operation and has really been reacting to the ensure he is supposed to take twice a day. Many things seem to give him diarroah and gas, yet he has been told to stick to a normal diet. Can anyone help with advice on meals, how often to eat and drink? Any advice on how he can be relieved of his symptoms and gain weight so he can recover would be really appreciated
