What Is The Main Cause Of Diabetes?
Показать описание
Diabetes occurs when your blood sugar (also called blood glucose) is higher than it should be. You need a certain amount of glucose because it's the main source of your body's energy. But too much glucose can do life-threatening damage to your body.
Insulin, a hormone made by the pancreas, helps glucose from food get into your cells to be used for energy. When your pancreas isn't producing the right amounts of insulin, you become "diabetic."
There are two types of diabetes, and usually just called "Type 1" and "Type 2."
What Causes Type 1?
Type 1 diabetes is caused by a malfunctioning immune system, which is your body's system for fighting infection. When you have type 1, your immune systems attacks and destroys the insulin-producing cells in the pancreas. Medical research seems to indicate type 1 diabetes is caused by genes and environmental factors, such as viruses.
Type 1 diabetes was once known as juvenile diabetes because it usually struck children due of a hereditary predisposition.
What Causes Type 2 Diabetes?
Type 2 diabetes occurs due to a number of factors, including genes, lifestyle choices, and diet.
Type 2 diabetes usually begins with a condition known as insulin resistance, as your muscles, liver, and cells do not use insulin as they should.
Sedentary people who are overweight or obese are prime candidates for type 2. Lack of exercise and extra weight can contribute to insulin resistance.
As with type 1 diabetes, your family history may make you more likely to develop type 2 because it tends to run in families. Genetic factors also can increase the risk of type 2 diabetes by increasing a person’s tendency to become overweight or obese.
