Hi, Welcome to Health care magic forum.
There are so many other factors to be seen for surgery, like block of other arteries, the degree of block, and the factors for block etc.
Sedantary,
obese, and smoker, and probably with
high cholesterol, and atherosclerisis. So first of all these factors are to be controlled before the surgery is done.Other wise there could be recurance of the block.
If the habits, and obacity continues, soon it may lead to the complete block, and
stroke may occur.
Take more of green leafy vegetables, pulses, sprouts,
and protein rich foods, and fruits to prevent any hazards.
She should stop
smoking, practice
yoga, morning walk, etc.
Wishing for a quick and complete recovery.
