What term is used to describe menstrual cycles that are shorter than 21 days?
Answer
Polymenorrhea
Polymenorrhea is the clinical designation for menstrual cycles that occur at intervals of fewer than 21 days. When cycles occur this frequently, it may indicate that the body's internal hormonal communication systems are reacting to external or internal factors. Frequent cycles are often flagged for further investigation to ensure there are no underlying health conditions, such as luteal phase defects, affecting the regularity of the endocrine system.
