Amenorrhea and Eating Disorders


Amenorrhea is the abnormal absence of the menstrual cycle. Irregular menstrual periods can be brought on by experiencing the stress associated with an eating disorder and also by dropping the percentage of body fat to below 22 or 23 percent. With the decrease in the level of body fat, the pituitary loses its ability to stimulate the ovaries. Decreases in estrogen and progesterone lead to amenorrhea and over time, osteoporosis may develop.
