Did you know that gestational diabetes occurs during 2-10%
of all pregnancies? As new ways of
classifying and diagnosing gestational diabetes emerge that number could rise
to as high as 18%.
Gestational
diabetes is a type of diabetes where women who have no history of diabetes have
above normal blood sugar levels during pregnancy due to increased
hormones. Most of the time, it
disappears after the pregnancy is complete.
The following is how the American Diabetes Association describes
gestational diabetes.
“The placenta
supports the baby as it grows. Hormones from the placenta help the baby
develop. But these hormones also block the action of the mother's insulin in
her body. This problem is called insulin resistance. Insulin resistance makes
it hard for the mother's body to use insulin. She may need up to three times as
much insulin.
“Gestational diabetes starts when your body is not
able to make and use all the insulin it needs for pregnancy. Without enough
insulin, glucose cannot leave the blood and be changed to energy. Glucose
builds up in the blood to high levels. This is called hyperglycemia.”
There are quite a few risks with gestational diabetes. One of the main ones is having a “fat” baby. This can happen because the baby will develop
high blood sugar, which causes the pancreas to make high amounts of insulin and
that extra energy is stored as fat.
These children are at a higher risk for developing type 2 diabetes later
in life. Other complications while
giving birth can arise for mom and baby when the baby is too large.
Of women who have gestational diabetes, 35-60 percent will develop type
2 diabetes later in life. This could
happen immediately after pregnancy or 20 years down the road.
One way to diagnose gestational diabetes is to do an oral glucose
tolerance test. This is when the mother
drinks a solution containing a certain amount of glucose (usually 75g) and then
has their blood sugar tested at certain intervals after it’s finished. This test can be done at your doctor’s office
and is usually done between weeks 24-28.
