In brief: Missed period

By far the most common is stress, which disrupts the normal cycling of hormones.
Other conditions include blockage due to scarring at the opening of the uterus, certain autoimmune disorders which attack either the ovary or the pituitary, certain pituitary tumors, obesity, anorexia nervosa, and marathon running (all interfere with hormone levels).
