I don’t want to write about gestational diabetes here, there is a lot of Wikipedia to read.
I can write about my experience with gestational diabetes.
How to prevent it:
I had a complicated pregnancy and hence was advised bed-rest. For those who can walk, it is the best way to burn sugars. Walk regularly.
Avoid eating refined sugars after 6 months. During the last trimester many families in India would feed you with loads of milk sweets and ghee as the baby grows the maximum during the last trimester. So does gestational diabetes.
My doctor noticed a little extra amniotic fluid and suspected gestational diabetes. After doing my glucose tolerance test we noticed that my sugars after fast were a little high.
My doctor put me on a 2000 calorie diet and asked me to monitor my sugars. The diet was the usual diabetic diet with half a liter of sugarless milk. I hate milk so had to skip that step, I made up with yogurt.
But then my sugars kept fluctuating, and since mine was a high risk pregnancy. I was put on insulin directly. I was given two insulin guns one for the day and one during the night. Also, I maintained a very strict diet with no sugar or rice.
It’s not very painful to take these shots; I used to take them on my hand. Try to avoid muscles, just pinch the flesh and click the pen.
I would say if your doctor advices you go for it.
My diabetes was gone immediately after my baby was born. So till then yes it will always be behind your head that something is wrong or might go wrong. I can only say be positive and follow the first few points and prevent gestational diabetes if you can if not take it seriously and follow your doctor.
