It distinguishes between gestational diabetes (type A) and diabetes that existed before pregnancy (pregestational diabetes).

It is typically determined from ultrasound imagery and can be used to estimate gestational age.

An average gestational period (duration of pregnancy from the first day of the last menstrual period up to delivery) is 280 days.

The rates of small for gestational age infants appear high (45 1000) with the most likely explanation being that it reflects maternal nutritional deficiencies.

Type 2 diabetes makes up about 90 of cases of diabetes, with the other 10 due primarily to diabetes mellitus type 1 and gestational diabetes.

Gestational trophoblasts are of particular interest to cell biologists because, like cancer, these cells invade tissue (the uterus), but unlike cancer, they sometimes know when to stop.

A variety of factors, such as gestational age, postconceptional age and birth weight needs to be taken into account when deciding if a blood pressure is normal in a neonate.

The measurement of CRL is useful in determining the gestational age (menstrual age starting from the first day of the last menstrual period) and thus the expected date of delivery (EDD).

Gestational hypertension or pregnancy induced hypertension (PIH) is the development of new hypertension in a pregnant woman after 20 weeks gestation without the presence of protein in the urine or other signs of preeclampsia.

Birth defects are not currently an identified risk for the child of women with gestational diabetes, since those primarily occur in the latter part of pregnancy, where vital organs already have taken their most essential shape.

This is in contrast to diabetes mellitus type 1 in which there is an absolute insulin deficiency due to destruction of islet cells in the pancreas and gestational diabetes mellitus that is a new onset of high blood sugars associated with pregnancy.

Follow up Follow up is necessary in all women with gestational trophoblastic disease, because of the possibility of persistent disease, or because of the risk of developing malignant uterine invasion or malignant metastatic disease even after treatment in some women with certain risk factors.

Conditions There exist several hypertensive states of pregnancy Gestational hypertension Gestational hypertension is usually defined as having a blood pressure higher than 140 90 measured on two separate occasions, more than 6 hours apart, without the presence of protein in the urine and diagnosed after 20 weeks of gestation.
