kidney function
At 80 years old, kidney function typically decreases to about 30-40% of what it was in early adulthood. This decline is a natural part of aging and can vary depending on individual health factors. Regular monitoring and management of kidney health are important for elderly individuals.
More than likely, it means that if you consider that 'normal' kidneys function somewhere between 90-100%, 30 % would indicate poorly functioning kidneys.
Kidney stones are most common among male Caucasians over the age of 30, people who have previously had kidney stones, and relatives of kidney stone patients.
Well obviously your kidney has to be failing. but other than that you have to have below 30% function in your kidney. Note: you can survive with only 1 kidney so its more like below 30% function in 1 kidney When your kidney function is down to 12 -15 % then you will need to do dialysis or have a kidney transplant. For a transplant the donor's kidney has to be suitable for you. Blood types and tissues types are matched to get as close a match as possible. Some body like a close relative is a good donor. The donor should have no major health problems and the recipient should have no other major health problems apart from the kidney failure.
Google can function as a calculator also, but the answer is 690.
GFR means glomerular filtration rate. It is a way to measure the kidney's function. In adults the GFR should be somewhere between 100 and 130, while in children it should be about 110. Since the GFR is a measure of the kidney's function it is used to help classify kidney disease. GFR > 90 with no signs of kidney damage like proteinurea = normal GFR > 90 with signs of kidney damage = Category 1 GFR 60-90 = Category 2 (mild) GFR 30-60 = Category 3 (moderate) GFR 30-15 = Category 4 (severe) GFR < 15 = Category 5 (kidney failure)
The function f(x) = 1.3*x
The kidneys are typically considered fully developed by the end of adolescence, around the age of 18. However, they continue to mature functionally into early adulthood, with some aspects of kidney function reaching their peak between the ages of 20 and 30. Factors such as genetics and overall health can influence kidney development and function as well.
Life expectancy can vary with only 30 percent heart function. Some people can live more than 5 years and some only a year. Quality of life isn't great with a low functioning heart.
"Percent" = "of 100". So 30 is 30% of 100.
