Gestational diabetes is considered the most common health problem associated with pregnancy, affecting between 2 and 18% of all pregnancies. You suffer from gestational diabetes when you have no personal history of diabetes, but suffer with high blood glucose levels during your pregnancy.
Gestational diabetes is believed to result from the presence of the pregnancy hormone hPL in your body. hPL inhibits the ability of your cells to take up insulin, which is secreted from your pancreas into your blood as part of your metabolic process. This causes your blood glucose levels to drastically increase.
You will more than likely be tested for gestational diabetes between week 24 and week 28 of pregnancy as this is when most pregnant women develop the condition. More often than not you will not exhibit any symptoms, therefore almost every woman is tested.
