Should you be required to prove you can’t lose weight by diet before weight loss surgery?

Mr

Our friends girlfriend has left to the USA (from canada) to get gastric bypass surgery. She looked into getting it in Canada but the doctors she met with had guidelines she had to meet. One being she had to attempt to lose the weight with restricted diet first. She denied that option and instead choose to go to the USA to receive the surgery. The only requirement she was given there was to be over a certain BMI and to follow a diet 1 week prior to surgery.

If you don’t know about gastric bypass surgery it is major surgery where they make changes to the size and shape of your stomach through removal. From surgery onwards you must forever maintain a strict diet, eating small meals often and ensuring you eat nutritious meals or a risk of malnutrition is high. After surgery, for the rest of your life, you run a high risk of malnutrition disease due to your body not absorbing nutrients the same way and your inability to eat as much.

So...should it be an 100% requirement to prove to the clinic you cannot lose weight through diet prior to surgery?

Or, your body your choice?
