is bypass operations that bad and are their sideeffects?

Answer 1

Yes, there are many, e.g. Renal failure and sepsis, and many more.
Much depends on surgeon, hospital care, and more of good luck.

Answer 2

Bypass operations are no picnic. My father had one on 9/11/01 (yes, it was a great day for me all around) and when I went to see him in the hospital I was in shock. Keep in mind, the surgeon is sawing your chest open and cutting into your body's most vital organ---there is going to be pain afterward, mainly in the chest. My father had to hold a pillow to his chest every time he coughed, and he did cough a lot because post surgery there is fluid that gathers in the lungs and it needs to be brought up. The good news is that the hospital stay is short---my dad was in for less than one week, and recovery at home took about two weeks. He slept upright in a chair because he was afraid of developing blood clots, which can be a side effect, and he also made sure to get up and get moving every single day even if it was only for a few minutes. You will be very weak afterward, but you've got to get up and keep moving. My father did recover beautifully, and he is healthy today.

Answer 3

Some people won't heal well. The usual other surgery risks. It is done so frequently that it is very routine with few surprises, so few negative results.

Some people won't survive without one.

If you are otherwise healthy, it is not that bad. That can happen. I had a strong heart and exercising. With sudden severe chest pains, doctors did an angiogram, and two of three arteries were 99% blocked. Surgery the next morning.

You feel pretty bad for about a week, but it heals, and you get better, mainly tiring easily.

Answer 4

Unless those arteries or coronaries are blocked at a high level like 75 % and up I will consider changing my diet into a vegetarian diet. Dr Ornish MD has prove that his diet works and reduce arteries plaques therefore avoiding invasive procedure like Bypasses. Yes they have side effects and usually you have to go back the next 5 years & they are extremely risky. 1 BIG advice to you : GO VEGETARIAN even better FRUITARIAN and you won't have to worry about bypasses etc..
