Type 1 Diabetes:

Type 1 diabetes is also called Juvenile Diabetes, Insulin dependent diabetes or Autoimmune Diabetes. Person with type 1 diabetes has immune response against his own beta cells of pancreas, so pancreas is unable to produce insulin at-all.That is why it is called as autoimmune diabetes. Juvenile diabetes usually occurs in children but can appear at any age. To live normal life patient has to take insulin and take regular exercise and has proper diet plan. The main cause of this type 1 diabetes are environmental factors like virus, diet or chemicals in people genetically predisposed.

It is usually seen in adults. There are two mechanisms of type 2 diabetes. Either there is deficiency of insulin, or there is increase resistance of insulin. Insulin resistance means that body is unable to use available insulin.The main cause of this type of diabetes is genetic however other factors like overweight, obesity, high blood pressure, lack of exercise, overeating habits may also affect.About 80% of people with type 2 diabetes are overweight.

However later, you may need insulin injections as well.

Gestational Diabetes:

Some women who develop diabetes during later stages of pregnancy is called as Gestational diabetes. Though their glucose levels returns to normal but even then they have greater chances of developing diabetes mellitus within next 5 to 10 years. Women with gestational diabetes may have no symptoms at all. The cause of gestational diabetes is hormonal imbalance during pregnancy or insufficient Insulin. Child of women who develops gestational diabetes is also at high risk of developing diabetes in later life.
