What Causes Gestational Diabetes

Doctors are unsure what causes gestational diabetes, but it is widely accepted that you are at a higher risk if there is a family history, or if you are an older mother. There are theories that hormones produced during pregnancy can impair the effectiveness of insulin.
The result is that you are unable to lower blood glucose levels to normal levels.

Gestational Diabetes normally manifests between weeks 20 to 24 of the pregnancy and usually increases in severity as the placenta grows.
The pancreas usually can cope with this by increasing insulin production, but in some cases, it is unable to deal with the increased stress placed on it and gestational diabetes occurs.
