Hello and Welcome to healthcare magic forum!
Thanks for the query!
Most people live normal, healthy lives with one
kidney. However, it's important to stay as healthy as possible, and protect the only kidney you have.
In general, most people with a single, healthy kidney have few problems. However, some long term problems have been seen in some people.
In some people who were born with a single kidney, or had a kidney removed during childhood, there is a chance of some slight loss in kidney function later in life. This usually takes 25 years or more to happen.
There may also be a chance of having
high blood pressure later in life. However, the loss in kidney function is usually very mild, and life span is normal.
Advise her to folow healthy lifestyle ofcourse people in villages dont have much lifestyle problems
but she has to avoid high salted foods and as she nears 40 or 45 she needs to keep a record of her BP and Sugar and if she has any habits like chewing or
smoking tabbacco kindly ask her to refrain from that,
Hope this helps
Wishing her good life!
