My daughter had a gastric band fitted in 2003 and came close to death. The surgeon punctured her stomach and did not visit her after the surgery. She suffered massive internal bleeding and had to have an emergency operation . The wound became infected, she developed vasculitis and then a huge incisional hernia. She had to be given Tramadol because she was in agony and became hopelessly addicted. Her life has been ruined. That was in a BUPA hospital. It took seven years of fighting the Medical Defence Union to get settlement of her medical negligence case. My advice to anybody considering this operation is DON'T DO IT. Just do some research on the failure rate, and even the mortality rate.
Surgery does not address the underlying problems that led to weight gain. Some patients were found to be liquidising Mars Bars because their attitude to sweet food had not changed.
To think that London, or anywhere else for that matter, does not belong to any one demographic
