Amenorrhea is defined as the absence of menstruation for three or more consecutive months. This condition can be categorized into two main types: primary amenorrhea, where menstruation has not started by age 15 or within five years of breast development, and secondary amenorrhea, which occurs when a woman who has previously menstruated experiences an extended period without a period. Various factors can lead to amenorrhea, including hormonal imbalances, stress, significant weight loss, excessive exercise, or underlying health conditions.

The other options do not pertain to menstruation. Strain and sprain refer to injuries involving muscles and ligaments, respectively, and pneumothorax is a medical condition related to air in the pleural space of the lungs, impacting respiratory function. Thus, these options are unrelated to the condition of amenorrhea.
