A 23-year-old woman in China experienced a cessation of menstruation and hormonal changes resembling those of a 50-year-old due to excessive exercise. Doctors diagnosed her with exercise-associated amenorrhea, a condition where the body conserves energy by temporarily shutting down reproductive functions. She was advised to stop exercising and prescribed traditional Chinese medicine for recovery. The woman noted this occurred after months of intense workouts, six times a week, despite previous periods remaining normal even after illness-induced breaks.
