What health problems are needed in order to qualify for gastric bypass surgery?

[kitson]

What types of health problems are needed to qualify to have gastric bypass surgery? Do you only qualify if you have severe health problems caused by this or could you qualify if you have smaller health problems like knee arthritis & breathing problems? Most of my family is obese and have heart disease, sleep apnea. Would they take that into consideration? My sister had gastric bypass surgery with a starting weight at 208 and is down to 128. I don't think she had any medical problems due to her obesity.

I think being fat is one of the requirements.
