Question

How long can a person live with one kidney?

Answer 1

The kidneys are one of the body's most important organs. Kidney failure can result in significant sickness or even death. The construction and function of each kidney are extremely intricate.
They serve two crucial functions: flushing away dangerous and poisonous waste products and maintaining the equilibrium of water, fluids, minerals, and chemicals, such as electrolytes like sodium and potassium.

Complete answer:
With just one kidney, most people can live long, healthy lives with few health issues. If you only have one kidney, though, your chances of getting fluid retention and high blood pressure are significantly increased.
However, renal function loss is usually minor, and life expectancy is normal. The majority of people who only have one kidney live healthy, typical lives with few issues. To put it another way, one healthy kidney can do the job of two.
Reasons for having one kidney may be-
It's possible for someone to be born with only one kidney. Renal agenesis is the medical term for this disorder. Kidney dysplasia is a disorder in which a person is born with two kidneys, but only one of them functions. The majority of persons born without a kidney (or with only one functioning kidney) live regular, healthy lives.
One kidney may have been removed during an operation to treat an injury or a condition such as cancer.
One of a person's kidneys may have been donated to a person who required a kidney transplant.

Note:
Functions of kidneys-
The kidney's primary role is to maintain whole-body balance. The acid-base balance, electrolyte concentrations, extracellular fluid volume, and blood pressure are all regulated by the kidneys.
The kidneys assist in the removal of a variety of waste items, which are then excreted in the urine. Urea and uric acid are the two most essential components that the kidney eliminates.
Kidneys are also in charge of reabsorption of nutrients from the blood, as well as transporting those nutrients to the parts of the body that promote health.
