In our experience the between 50 to 60% of pregnancies are suspended for via caesarean section reached the term for any of the complications mentioned earlier, which originates increase in rates of prematurity in infants. As in any other types of diabetes risks of poor control blood glucose during pregnancy confers risk of complications at the birth (neonatal) babies as they are: the Fetopatia diabetic: which manifests as: Macrosomia: 4 Kg or more weight at birth. Syndrome of respiratory difficulty (SDR), which is the ncapacidad breathing due to immaturity of the baby’s lungs. Hypoglycemia (low sugar) in the first 24 hours of life.

Hypocalcemia: decrease of calcium in the blood that can be translated into colvulsiones other risks potentials are delayed intrauterine growth restriction and the late death, which occurs between 38 to 39 weeks (intrauterine Fetal death) follow-up: despite the potential risks, our index of children born alive, similar to as it happens in other parts of the world, is 85%, and this is due to the advances in the fetal monitoring, which allows us to timely detect complications, as well as to the improvement in the types of insulin and its application form, that allow us to have better metabolic control during this important stage for the binomial and their families. Endocrinology service after the recruitment of patients, which on average is done at 18 weeks, on his first visit makes them an extensive clinical history and requested them laboratory tests aimed at assessing the previous metabolic control, as well as specialized medical evaluations to detect or rule out chronic complications.
