[The use of vegetable fibers in the treatment of pregnancy diabetes and/or excessive wight gain during pregnancy].

Vegetable fibres with a high viscosity reduce the levels of basal and post-prandial glycemia in both normal and diabetic subjects. The paper reports the results of a study to asses the value of glucomannan and guar in the treatment of excessive wight gain in pregnancy and gestational diabetes. Thirty-four patients were included in the study, of which 13 received glucomannan (3 g/day) and 21 guar (10 g/day). An oral glucose tolerance test was performed in all patients before and after therapy. A diminution of basal and post-OGTT glycemia values was observed in all subjects.
