You are having slightly high post meal blood sugar levels and suggest that you are are having mild gestational diabetes
.This type of diabetes occur in 2to 4% of pregnancies and results from muslin resistance .Since significant insulin resistance
develops in third trimester of pregnancy
,gestational diabetes sets only in in this period.
Usually blood sugar is normalised after delivery.
Women having gestational diabetes are at higher risk of developing type 2 diabetes during later part of their life.
It is said that 50% of females developing gestational diabetes get type 2 in next 10 to 15 years.
To control your blood sugar level ,cut down on sugary foods and drinks that contain caffeine such as coffee and cola. Take frequent small snacks rather than a few large meals which put a strain on your body.
A few women with very severe gestational diabetes that can't be controlled by diet and exercise may be prescribed insulin injections.
Your baby won't have diabetes.
I hope it helps.
