What Causes Diabetes?


A hormone called insulin controls blood sugar levels in our body. When the body is unable to generate enough insulin or cannot utilize the insulin generated by the body, sugar levels in blood shoots up. High sugar levels in your blood can affect the functions of various body parts like heart, kidneys, eyes, and brain. Chronic kidney disease and kidney failure are dangerous side effects of diabetes. There are two types of diabetes.

Type 1: This is generally seen in young people whose bodies are unable to produce enough insulin.

Type 2: This is common in adults over 40 years. This has a connection with obesity and some may inherit it from the family as well. In this type, the body produces insulin but fails to utilize it properly.

How does Diabetes Affect Kidneys?

How does diabetes affect kidneys?


High blood sugar damages small blood vessels in the body. The kidneys’ main function is to clean your blood. With diabetes damaging its blood vessels, the kidney cannot perform its task with efficiency. This leads to excessive water and salt retention in the body which leads to weight gain and ankle swelling. Protein in urine is another side effect. If the situation persists, waste materials are built up in the blood. Another major side effect of diabetes is damaged nerves. It makes emptying the bladder difficult for the body. Full bladder creates pressure that injures the kidneys. A person can develop an infection if urine remains in the bladder for a long time. Generally, urine with a high sugar level encourages the growth of bacteria which can cause infection.

How Many Years does Diabetes Take to Damage Kidneys?

Functional change in the kidneys is observed within a span of two to five years in patients with Type 1 diabetes. Out of them, 30 to 40% develop a serious illness related to kidneys. The time diabetes takes to damage kidneys is 10 to 30 years for Type 1 diabetes patients.

Type 2 diabetes generally occurs at an older age. If not controlled, it similarly takes 10 to 30 years to damage kidneys irreparably.

Most patients do not have symptoms during the early stage of kidney damage. If you have diabetes, it is advisable to undergo a urine test at least once a year. If there is a protein named albuminuria in the urine even in the small amount, the test can detect it and indicate the early stage of kidney damage. Bear in mind that it is not necessary that kidney disease leads to kidney failure. If you receive the right treatment at the right time, you can control kidney disease from worsening.
