The risk for sub-optimal nutritional status and consequently a potential risk of developing micro and macronutrients deficiencies in post bariatric pregnancies, are higher compared to non-surgical pregnant women, given the nutrition challenges brought about by the surgery such as food aversions, nausea, and vomiting beyond the increased nutritional requirements exist in healthy pregnancy. Furthermore, even without the existence of nutritional deficiencies, maternal diet quality has a critical effect on fetus. "Western" diet, high in fats and sugars, increased sympathetic nervous system activity and hyperactivity in rodent offspring that persisted into adulthood. However Investigation of diet quality during pregnancy among women with bariatric surgery has shown that 82% of women's diet quality needs improvement. Moreover, dietary modifications are mainly directed towards increased pollution safety rather than improving diet quality in order to improve the mother and the fetus' nutritional status.
