Certain medical conditions may complicate a pregnancy. However, with proper medical care, most women can enjoy a healthy pregnancy, despite their medical challenges. What causes gestational diabetes?
Although the cause of gestational diabetes is not known, there are some theories as to why the condition occurs.
The placenta supplies a growing fetus with nutrients and water, as well as produces a variety of hormones to maintain the pregnancy. Some of these hormones (estrogen, cortisol, and human placental lactogen) can have a blocking effect on insulin, which usually begins about 20 to 24 weeks into the pregnancy.
As the placenta grows, more of these hormones are produced, and insulin resistance becomes greater. Normally, the pancreas is able to make additional insulin to overcome insulin resistance, but when the production of insulin is not enough to overcome the effect of the placental hormones, gestational diabetes results. Treatment for gestational diabetes:
Specific treatment for gestational diabetes will be determined by your physician based on: • your age, overall health, and medical history • extent of the disease • your tolerance for specific medications, procedures, or therapies • expectations for the course of the disease • your opinion or preference
