The two major female sex hormones in the body are estrogen and progesterone, produced in the ovaries start producing large quantities of estrogen when the girl reaches about 12 years of age. The commencement of menstruation at this time indicates the start of the reproductive phase of her life, when she can start having children. The main problems relating to the menstrual flow are pre – menstrual tension, painful menstruation, excessive menstruation and poor or absent flow. It has been shown by different studies that most menstrual difficulties are due to a deficiency, an excess or improper metabolism of female hormones. Vitamins E, B, C, PABA and folic acid affect the estrogen levels and the metabolisms involved during menstruation. Nutrition plays a vital role in the prevention and treatment of most ‘menstrual disorders’.
