Nutritional deficiencies in morbidly obese patients: A new form of malnutrition? Part A: Vitamins

It is a common belief that clinical vitamin or mineral deficiencies are rare in Western countries because of the low cost and unlimited diversity of food supply. However, many people consume food that is either unhealthy or of poor nutritional value that lacks proteins, vitamins, minerals, and fiber. In this, article we reviewed the literature and highlighted the vitamin deficiencies in obese patients before bariatric surgery. Deficiency of dietary minerals is described in the accompanying manuscript. The prevalence of vitamin deficiencies in the morbidly obese population prior to bariatric surgery is higher and more significant than previously believed.
