My GP phoned me today after my booking bloods (I'm about 9 weeks) and told me I have to go to hospital for a glucose tolerate test because my booking bloods came back with a blood sugar level of 13.2. She asked if there is family history of diabetes, and my mother and grandmother both have type 2, but they are obese and I am only 8 stone. I am under thirty and this is my second pregnancy; the blood sugar being normal in my first one. I had my bloods taken in the morning, so I had toast not much more than an hour before hand. I've also started drinking flavoured sparking water which contains sugar, because I feel constantly sick and cannot eat a great deal. It leaves me feeling very dizzy so I started drinking the sugary drink which helps me to feel a little better. Do you think it is just the sugary drink or is my reading too high for that?
When I called the hospital the lady I spoke to seemed very surprised by my reading and said I'd need to go in early next week because it was "so high". Is it that high? Could one sugary drink do that?
I'm freaking myself out because I Googled gestational diabetes and see that some people believe it can cause birth defects, but that as GD isn't usually a problem until later 2nd or 3rd trimester, when the foetus is well-formed, it's not often a problem. Obviously, I'm in my first trimester. I'm also concerned because I take a medication which increases the risk of birth defects anyway.
Have other people had a high reading at their booking bloods and then a normal glucose challenge? Can a drink affect for blood sugar that much? I know I'll have tests next week, but I don't want to worry unnecessarily for the next four or five days if it is quite common to get a high reading not long after breakfast. Thanks!
