Causes of Diabetes

Causes of diabetes can be due to any defect in the insulin production, insulin action or both, diabetes is a diseases marked by high levels of blood glucose.

What are the causes of diabetes

The exact diabetes causes of both types are still unknown even after many scientific researches. But still managed to identified some general diabetes causes.

Type 2 diabetes causes
In a healthy individual, the pancreas releases insulin to help the body to store and use the glucose from the food, we eat. Type 2 diabetes causes may be any one of the following:

• Pancreas does not able to produce enough insulin and causes diabetes.
• Body does not properly respond to insulin (that is not sensitive to insulin), a condition called "insulin resistance", which causes diabetes
• Or both shortage of insulin and insulin resistance.

Type 1 diabetes causes
Some genes may be behind the type 1 diabetes causes, but mostly it is triggered by the following:

• Auto immune disorder, our body immune system itself attacks by mistakenly identified as enemy and destroys the insulin-producing cells of the pancreas. Thus pancreas losses its ability to produce insulin and can cause diabetes.
• Pancreas beta cells damaged by cystic fibrosis or pancreatic surgery can cause high blood glucose called diabetes.

Gestational diabetes causes
Gestational diabetes is metabolic disorder happens during the later stages of pregnancy. It is difficult to pinpoint the gestational diabetes causes, but have some clues of its causes.

During pregnancy the fetus is provided with necessary nutrition via placenta. Placenta not only supplying the nutrition to the fetus, but also releases some hormones like cortisol and estrogen. These hormones are essential for the health and growth of the fetus. Unfortunately these hormones block the insulin receptors of the cells, which causes high level of blood glucose. It usually begin about 20 to 24th weeks of pregnancy.
