Pregnancy in women with type 1 diabetes mellitus is associated with an increased risk of preeclampsia, congenital malformations, obstetric complications, and neonatal morbidity. These adverse outcomes are related, at least in part, to preconception care, especially the level of glycemic control. Intensive glycemic control and preconception planning have been shown to decrease the rate of stillbirth and malformations seen in pregnant woman complicated by type 1 diabetes mellitus (DMT1). Correct management allows the prevention of maternal and fetal complications that are directly related to this pathology. It is also important that a postpartum follow-up check is carried out, which should be part of the comprehensive evaluation of the pati (publica, 2014)ent with diabetes. Furthermore, recent advances in insulin formulations and delivery methods have increased the number of options available to the obstetric team. In the present clinical case, it was decided to carry out a study om type 1 diabetes mellitus (DMT1) with a 27 year-old primigravid patient with 35.4 weeks of gestations, who presented at the Sagrado Corazón de Jesús hospital. In this way, the risk factors of said patient will be detailed.Pregnancy in women with type 1 diabetes mellitus is associated with an increased risk of preeclampsia, congenital malformations, obstetric complications, and neonatal morbidity.

Estos resultados adversos están relacionados, al menos en parte, con la atención preconcepcional, especialmente con el nivel de control de la glucemia. Se ha demostrado que el control glucémico intensivo y la planificación previa a la concepción disminuyen la tasa de muerte fetal y malformaciones observadas en embarazadas complicados por diabetes mellitus tipo 1 (DMT1). Un manejo correcto permite la prevención complicaciones maternas y fetales que se encuentran directamente relacionadas a esta patología. También es importante que se realice un control de seguimiento postparto, el cual debe formar parte de la evaluación integral del puerperio de la paciente que padece diabetes. Por otra parte, los avances recientes en las formulaciones de insulina y los métodos de administración han aumentado la cantidad de opciones disponibles para el equipo obstétrico. En el presenta caso clínico se decidió realizar un estudio sobre la diabetes mellitus tipo 1(DMT1) con paciente primigesta de 27 años con 35.4 semanas de gestación, el cual se presentó en el hospital Sagrado Corazón de Jesús. De esta manera se va a detallar los factores de riesgo de dicha paciente.
