Noninsulin dependent diabetes mellitus and pregnancy in Mexico

We analyzed 215 consecutive patients with diabetes mellitus and pregnancy, 118 (54.83%) with noninsulin dependent diabetes mellitus (NIDDM), 90 (41.86%) with gestational diabetes mellitus (GDM) and 7 (3.26%) with insulin dependent diabetes mellitus (IDDM). NIDDM and GDM patients had no significant difference in age and body mass index. There were no maternal deaths, nor episodes of ketoacidosis. Maternal and neonatal complications occurred with a similar frequency in NIDDM and GDM. We concluded that in our population, diabetes associated with insulin-resistance occurred in over 96% of our pregnant diabetic patients and was associated with an increased prevalence of maternal and neonatal complications. Earlier perinatal care has to be established in NIDDM patients, and obese young women should be screened to detect GDM from early gestation and advised to reduce weight before pregnancy ensues.
