Association between vegetarian diet and menstrual problems in young women: a case presentation and brief review.

In the last twenty years, several studies have suggested the existence of an association between vegan diets and adolescent menstrual disorders. We share our experience with this problem and a review of the literature on the subject. We conclude that despite the existence of some evidence to the possible association between vegetarian diet and menstrual disorders, it is still not clear if this association is due solely to the vegetarian diet or due to the overall inadequate nutrition with decreased proportions of fat and protein in the diet. We believe that more prospective, well controlled studies are needed to truly explain this association.
