This can be a two-edged sword. My brother was grossly obese. Started with prostate treatment with female hormones, then once that weight piled on, his bad knees from an on-the-job RTA as a cop got worse. So he was put on Oxycontin. He'd been on that for years and was unable to lose any weight...the two conditions created a vicious cycle. And he developed kidney trouble.
Heart disease runs in our family, but my dad lived to a very old age with himself getting overweight in the end once confined to a wheelchair because an MRSA foot wound infection did not heal and he lost muscle tone to walk. He had kidney trouble, too.
My brother had open heart surgery after a MILD heart attack just last spring. It was to be a quad bypass with an aorta valve replacement.
He came out of surgery and was on machines for almost two weeks. The trauma of the surgery was too much for his 74 year old body. They turned the life support off.
This is in America... land of 'you can get whatever health care you can pay for as long as your insurance company agrees with the consultant.'
He should not have had that surgery in that obese condition. He was over 24 stone! He had a MILD heart attack and probably would have had another eventually, but could have lived with his blockages and lost weight, and responded to kidney medication, before having the bypass.
Before they turned off the machines, his daughter was there and he opened his eyes. He could not talk with the intubation, but he heard her and knew what was going to happen. He cried... he knew he should have taken better care of himself. There is no second chance.
So there are huge risks to surgery for very overweight people, especially cardiac surgery.
