Due to a larger number of obese patients worldwide, there are higher rates of its related diseases, as well as complications of pregnancy and labor. Macrosomia is a consequence of the metabolic syndrome involving obesity, insulin resistance, and gestational diabetes mellitus. Beyond that point, inadequate and unbalanced intake of vitamin-mineral supplements also gives rise to abnormalities during pregnancy and after labor. Healthy lifestyle before and during pregnancy, balanced nutrition, and intake of essential micronutrients are a key to a healthy baby and a healthy mother.
