High blood glucose levels during pregnancy can also increase the chance that your baby will be born too early, weigh too much, or have breathing problems or low blood glucose right after birth. It can also induce still births in pregnant woman. Hence, speak with a doctor if glucose is high.

Hi Doctor, I am 29 weeks pregnant. I did my GTT test four days ago. My fasting was 88, 1 hour post 75 mg glucose was 179, and 2 hour post was 160. The doctor advised me to monitor blood sugar at home twice a day at two day intervals (FBS, after breakfast, after lunch, after dinner alternatively, and 1 hour post meal). On 13th, my fasting was 78, and 1 hour post lunch was 115. On 14th, 1 hour post breakfast was 157, and 2 hour post breakfast was 117. Today, 1 hour post breakfast was 161, and 2 hour post was 102. Are my readings correct? I am a bit worried. The doctor told me to measure only 1 hour post readings, but I am also measuring 2 hour readings. Please help me understand what I should do to control this diabetes? I also have PCOD and thyroid issues for the last four years.
