Overview

Gestational diabetes refers to hyperglycemia during the second or third trimester of pregnancy.

Classification

Gestational diabetes was referred to as any type of hyperglycemia that was not recognized or present prior to pregnancy. This definition is no longer used because of the increased number of females with type 2 diabetes and obesity who became pregnant without awareness of their pre-pregnancy glycemic status.^[1]

ADA classification

The American Diabetes Association (ADA) classifies GDM as diabetes diagnosed in the second or third trimester of pregnancy, that is not clearly either type 1 or type 2 diabetes.^[1]

White’s classification

White classified diabetes in pregnancy in to two groups:^[2]

Type A1: Controlled by diet and exercise
Type A2: Requires insulin for treatment
