Differential Diagnosis

Premature ovarian failure, rapid weight loss, extreme physical exertion, low body mass index (BMI) as in anorexia nervosa, and pregnancy will cause abnormal menstrual cycles ( Table 2 ). Discontinuation of oral contraceptives may also cause amenorrhea. The latter is called post-pill amenorrhea. A pituitary adenoma, hyperthyroidism, or hypothyroidism will also cause a change in the menstrual cycle.

Other important etiologies to consider include congenital adrenal hyperplasia, late-onset adrenal hyperplasia, and Cushing's syndrome. Tumors of the adrenal gland or the ovaries may also present with menstrual irregularities.[8,9,16]
