This type of diabets can be either Type I or Type II. It has not been determined if the diabetes is solely a function of the Pregnant state, or if it reveals an underlying diabetic condition by hyperglycemia, hyperlipoproteinemia (increase in blood lipoprotein), and hormone secretion by the placenta. Tissue resistance of insulin is increased, thereby increasing levels of blood insulin, glucose, and triglyerides. This occurs due to a placental lactogen and increased estrogen and progesterone levels. The fuel cenides requirement of the fetus is primarily from mother's glucose, but the fetus produces it's own insulin. Hyperglycemia during the first four to eight weeks of pregnancy result in congenital anomalies. Successful pregnancies are obtained through prepregnancy counselling and evaluation. Diabetic women who carefully monitor and control their glucose levels have healthy mormal babies.
