I joined 16 years ago. Had five bypasses. No sad stories here. It was one of the best things that ever happened to me physically.
I was obese and a couch potato due to a chronically bad back, on which I had two surgeries over the years. Although grossly overweight, I was fairly active, and did a lot of walking for exercise, which may have helped save me. The chest pains during walking got worse and worse.
I finally went to have it checked out, was 100 percent blocked on one side and 80% on the other. Why I never had a heart attack I don't know. The doctor said that in about 20 % of cases the body will develop small capillaries around the blockage and that is what I was living on.
After surgery the hospital dietician gave a lecture on proper diet. I instantly became a low-fat fanatic, and began the exercise program they gave me. First week was just shuffling my leet around the den for ten minutes, gradually working up. In a year I was walking six miles a day. I lost 55 pounds, down to 245 (I am 6'8" tall.) Took up running, stess cracked a foot, broke a metatarsal, and while I was on crutches noted the muscle I added in shoulders, abs, and arms from hauling 245 pounds around on crutches. Took up weight training, gained back to 265 pounds with no increase in waist size. Although I will never be in a body building competition, I proved that 50+ year old men could still add considerable muscle. Four years after surgery, I had a follow-up arteriogram and the doctor said that I had the heart of a man who had "never had any heart problems at all."
Two years ago I had another arteriogram and the doctor says that the bypasses look brand new and I have a "magnificent heart muscle." Tody at 64 I still do heavy-duty, Mentzger style weight training and still weigh 265.
I have not eaten a doughnut, a potato chip, a fast-food burger, french fries, etc. since October 1994 and the thought of doing so repulses me. Luckily for me, I love fish, and prefer grilled fish to beef or pork anytime. I also eat so much chicken that every time a hawk flies over I have an impulse to hide. at some point in the process the back problems largely went away, and today I put 400 pounds on a weight machine and do back flexions, after living for years under doctor's orders to never lift over 20 pounds.
It was truly a life-changing experience for me, for the better.
