Band or bypass?
I am due to have bypass on 5th July. I start my pre-op diet on monday 20th ready for the op. Mine is a 1000calorie diet or the milk diet which for me is opts milk, max of 2 low fat yoghurts and a cup of oxo a day with at least 2l free fluids (that's decaff tea, decaff coffee, water) tea and coffee you need to use milk from your daily allowance if you take them with milk.
I have no experience of the banders pre-op diet but someone will no doubt be along to share soon.
