Type II or NIDDM or non-Insulin dependant diabetes mellitus
Gestational diabetes that occurs during pregnancy.

The Islets of langerhans present in the beta cell of the pancreas are not able to produce adequate insulin (a protein required for metabolism of glucose). Type I or Insulin dependant diabetes mellitus or IDDM is typically

due to auto-immune damage of the pancreatic beta cells which produce insulin. Type II is insulin resistance and is a consequence of loss of beta cell functioning. Gestational diabetes that occurs during pregnancy is analogous to type II diabetes. In this it involves insulin confrontation; hyperglycemia or raised levels of glucose, is seen. The hormonal fluctuation during pregnancy leads to insulin resistance in those women hereditarily inclined to diabetes mellitus.

Diagnostic methods begins with oral glucose tolerance test i.e. OGTT. The fasting plasma glucose test calculates the blood glucose after eight hours of fasting. This test is used to perceive diabetes or pre-diabetic condition. The normal level is 100 mg/dl and below to it. An oral glucose tolerance test or OGTT measures the blood glucose two hours after drinking a glucose beverage. This test can be used in the diagnosis of diabetes mellitus and other pre and post conditions of diabetes. The standard value is 140 mg/dl and below to it.

In a arbitrary or random plasma glucose test, blood glucose is checked with no regard to when the person ate the last food. This test, along with a judgment of symptoms, is used to diagnose diabetes mellitus but not pre-diabetes Glycosylated hemoglobin (HbA1C) is another dependable indicator of the occurrence of the disease. This method offer the blood glucose levels for the preceding three months. The normal level is less than eight percent. The likelihood of suffering from diabetes mellitus is more in following

Over weights above 45 years of age
People with family history
Gestational diabetics
