Use of myo-inositol and other nutritional supplements for the primary prevention of gestational diabetes mellitus

Abstract

Gestational diabetes mellitus is the abnormal carbohydrate tolerance that begins during pregnancy and is considered a risk factor for the development of complications in the mother and fetus during pregnancy. Its prevention is based on lifestyle interventions, glycemia monitoring, and pharmacological and nutritional therapy. Nutritional supplements are presented as a promising alternative to treat and prevent this phenomenon. This literature review aims to determine the efficacy of myo-inositol as a prophylactic supplement to prevent the development of gestational diabetes mellitus and its complications, as well as to mention other alternative supplements. A search was conducted in Pubmed, SciELO, Elsevier, and Hinari databases, including original articles published between 2019 and 2023. The evidence found showed that myo-inositol supplementation in pregnancy increases insulin sensitivity, reduces low-density lipoprotein levels, reduces pregnancy-induced hypertension, and reduces the incidence of preterm delivery, fetal macrosomia, episodes of fetal hypoglycemia and neural tube defects, being its implementation safe in pregnancy. However, it is necessary to conduct research with a larger number of participants, with standardized doses that allow for establishing the efficacy of this supplement for its use as an alternative in the prevention of gestational diabetes.
