I wondered if anyone had this through a second pregnancy? Mine got diagnosed at the glucose tolerance test at about 25 weeks and after a week of monitiring sugar levels I was put on insulin 3-4 times a day which rose until I had the baby. Even though I put on no weight in the last 2 months and ate pretty healthily my sugar levels were out of control. I expect to get it if I have another baby and wanted to know how they treat it from day one? I had to go to the hosipital every weeks and see a midwife constultant and sometimes a dietician.
