As a nurse consultant in bariatric surgery (with 10 years in the speciality), the above post doesn't surprise me as one of the main reasons for choosing bariatric surgery is the bad experiences at the hands of ignorant HCPs!
Bariatric surgery is for morbid obesity. It isn't an alternative to diet and exercise for those who simply need to diet. Morbid obesity is a serious health problem and it is costing the nation highly in terms of NHS demands, sick pay etc.
Simply saying "cut down" is like telling someone that you will give them a million pounds if they hold their breath for 10 minutes. The motivation is there but they simply can't do it. Obesity is multifactoral. Clearly, there is a need to change eating and exercise habits but modern society doesn't easily support that change. Nothing is physical anymore and parents are scared to allow their children to play outside for fears to their safety.
Of course, we could ignore it and hope it will go away but that would lead to much sicker mothers and babies.
I'm not suggesting we pretend that diet and exercise aren't important. Simply suggesting that this patient group needs help, tolerance and understanding to support them through difficult changes.
Anyone thinking that bariatric surgery is easy and a cheat's way out is an idiot. Spend a day with a patient and then make up your mind. You may realise you don't have ALL the answers then.
