Types of Diabetes

Diabetes commonly refers to diabetes mellitus. A rare kind of diabetes, known as diabetes insipidus also exists. However, the 2 kinds of diabetes do not have any relationship between them. The most commonly seen form of this medical condition is diabetes mellitus. The differentiating point between them is that diabetes mellitus is the condition of high glucose levels in the blood whereas diabetes insipidus is the condition which relates to the inability of the kidney to conserve water.

4 major classifications exist for Diabetes mellitus. They are type1 diabetes, type2 diabetes, gestational diabetes, Latent Autoimmune Diabetes in Adults (LADA), Maturity -Onset Diabetes of the Young (MODY), pre-diabetes etc.

Type 1 diabetes can be further sub-divided into immune mediated diabetes and idiopathic diabetes. They are also called type1A and type1B respectively. Immune mediated diabetes accounts for only about 5-10% of diabetes cases. Also known as juvenile-onset diabetes, insulin independent diabetes etc, this form of diabetes is caused due to the cellular-mediated beta cell destruction of the pancreas. The destruction rate of cell destruction varies with individuals of certain age group. In children, the rate is high whereas in adults, the rate is slow. Certain forms of diabetes don't have definite etiological factors. This category is referred to as idiopathic diabetes.

LADA also called type 1 1/2-diabetes, it refers to a type 1 diabetes that develop only slowly. Some patients, who actually have diabetes of this kind, were falsely diagnosed of having type-2 diabetes.

Gestational diabetes is another form of this disease that develops during gestation (pregnancy) period. Usually, this diabetes disappears after the pregnancy period.

MODY is a disease that is strongly inherited. This kind is caused due to drastic changes in the autosomal dominant gene. The destruction hampers the production of necessary insulin. Both MODY & LADA are different in many aspects.

Pre-diabetes is another condition that is quite different from the above mentioned sub-divisions. The condition is often regarded as an intermediate condition between normalcy and diabetes. Equivalent names for such a condition are Impaired Fasting Glucose (IFG), Impaired Glucose tolerance (IGT) etc.

Diabetes insipidus has 4 subdivisions. They are central diabetes insipidus, nephrogenic diabetes insipidus, dipsogenic diabetes insipidus & gestational diabetes insipidus.
