The authors studied the content of immunoreactive insulin (IRI) during the glucose tolerance test (GTT) in 57 pregnant women at various periods of pregnancy and in 10 nonpregnant women at the same age. There proved to be a significant increase in IRI in the blood on fasting stomach and during the GTT in all the pregnant women examined. In the pregnant women with doubtful GTT results and latent diabetes the IRI content was significantly greater than in healthy nonpregnant women and in the diabetic women. There was a tendency to the increase of IRI content in the blood of pregnant women with an excessive weight in comparison with the pregnant women with a normal weight.
