Types, causes and symptoms of diabetes.

Diabetes is a medical condition in which the amount of glucose increases in bloodstream. Glucose is supposed to be absorbed by cells with help of a hormone called insulin. Cells need glucose to perform their functions. Sometimes, body cells don’t co-operate with insulin. As a result, glucose accumulates in the bloodstream and causes diabetes. Diabetes is of type 1 and type 2. There is also gestational diabetes (caused during pregnancy) and prediabetes (reversible high glucose levels which if increase further can turn into diabetes).

Type 1 diabetes

There are speculations about exact causes of type 1 diabetes. It is usually attributed to family history, genetic susceptibility, environmental reasons, geographical location and autoantibodies. It is usually experienced by adolescents. Doctors believe that in type 1 diabetes, immune system destroys insulin producing cells in pancreas and this prevents glucose from entering the cells; and it gets stored in the blood. The symptoms of type 1 diabetes are vigorous and come to attention at a very early stage. This diabetic type is extremely painful even though the severity depends on the blood sugar levels.

Type 2 diabetes

Prediabetes usually develops into type 2 diabetes. This diabetic type arises when the cells become insulin resistant and forces glucose to keep travelling in the blood. The causes of type 2 diabetes are obesity, reduced body activity, family history, age, gestational diabetes, less cholesterol and high triglycerides. Type 2 diabetes usually occurs after the age of 40. Symptoms of this diabetes aren’t revealed initially. They come into light gradually with time.
