Pregnancy is a physiological process that requires transformations in the female body, due to anatomical and hormonal changes. The body can understand that these changes, initially physiological, predispose to different pathological states, such as Gestational Diabetes Mellittus (GDM), which is characterized as maternal insulin resistance caused by an increase in diabetes hormones, such as progesterone, cortisol, prolactin and placental prolactin (GANDOLFI et al., 2019). Another definition is carbohydrate intolerance of varying severity, which begins during pregnancy and affects 3 to 25% of pregnant women (ZAJDENVERG et al., 2022).
