Kidney diseases and Aging

Kidneys can be affected or damaged by a variety of diseases and conditions. As we get older, we are more likely to suffer from kidney and urinary tract infections. Kidney problems can also increase the risk of other conditions such as cardiovascular (heart and blood vessel) disease and aging inhabitants. With aging there is a progressive reduction in kidney function amounting to about 1 percent loss with every passing year after the age of 40. Therefore an elderly person is more vulnerable to develop kidney failure in the face of any insult to the kidneys.

Types of age-related kidney disease:

Inflammation of the kidneys:

This is called acute glomerulonephritis, when the filters of the kidney become swollen and can cause the kidneys to fail within weeks.


This is the most common cause of chronic kidney disease in the world.

Urinary tract infection:

Urinary tract infections are very common, particularly in women and with increasing age.

Reno-vascular disease:

This affect the kidney’s filters and reduces the blood supply to the kidneys, resulting in high blood pressure and reduced kidney function. In elder person this is a common cause of kidney failure.


High blood pressure:

If left untreated, high blood pressure not only increases the risk of heart attack, and stroke, but also of kidney failure.

Obstructive kidney failure-various diseases can obstruct the flow of urine from the kidneys in elderly and kidney function is compromised by back pressure. Enlargement of the prostate gland in men, tumor of urinary bladder, and cancer of womb in females tends to occur in aging population and can cause obstruction.
