On the plus side, only 15% of those who take this test do end up diagnosed with gestational diabetes. So fingers crossed, although Kev says he suspects I have it, just based on how quickly I crash with tiredness sometimes, and how desperately I need food on occasion. And I have three risk factors: older than 30, family history of diabetes, and overweight. It wouldn't surprise me if I have it. According to the Mayo Clinic book, about 3-5% of pregnant women in the US develop g.d., so it's not so unlikely.
Why is g.d bad? "The major risk for babies of women with gestational diabetes is excessive weight at birth (macrosomia)....These large babies are at greater risk of birth injury than are others. Other problems that may develop as a result of gestational diabetes include low blood sugar (hypoglycemia) in the baby shortly after birth, jaundice, and respiratory distress syndrome.....If g.d. goes undetected, the baby has an increased risk of stillbirth or death as a newborn. But when the problem is properly diagnosed and managed, your baby is at no greater risk than is a baby whose mother doesn't have gestational diabetes." (Mayo Clinic Guide)
So, okay, clearly worth doing the test and finding out, even though the test is a pain and the disease itself causes me no symptoms at all. If diagnosed with g.d., then carefully monitored diet, regular exercise, and pricking my finger a lot (first thing in the morning, and after every meal) will be my lot in life for the next three months. If that doesn't work well enough to control my glucose levels, insulin shots. A nuisance, and you can expect to hear me whining if it happens, but really, not such a big deal as pregnancy complications go. They do tend to want to have the baby born a bit earlier, to reduce the risk of those birth injury complications, so C-sections become more common in these cases.
More of an issue is that about half the women with g.d. eventually develop regular diabetes. Sigh. We'll just have to keep our fingers crossed that tomorrow's test comes back negative.
