Diabetes cause due to mall functioning of pincrease

The three main types of diabetes are:

Type 1 diabetes

Type 2 diabetes

Gestational diabetes

Type 1 diabetes

Type 1 diabetes is believed to be an autoimmune condition. This means your immune system mistakenly attacks and destroys the beta cells in your pancreas that produce insulin. The damage is permanent.

Type 2 diabetes

Type 2 diabetes starts as insulin resistance. This means your body can’t use insulin efficiently. That stimulates your pancreas to produce more insulin until it can no longer keep up with demand. Insulin production decreases, which leads to high blood sugar.

Gestational diabetes

Gestational diabetes is due to insulin-blocking hormones produced during pregnancy. This type of diabetes only occurs during pregnancy.

• The Earth is tilted at an angle of 23.5 degrees.
• This tilt is responsible for the changing of the seasons and the difference in the amount of sunlight reaching a given point on the surface during the course of a year.
• The tilt varies between 22.1 and 24.5 degrees in a cycle that averages about 40,000 years.
