Why hasn't my 11-year-old daughter's period stopped after more than ten days?
Disease description:
My sister is 11 years old. Her menstrual period started 10 days ago, but it hasn't stopped yet—it's been over ten days. What could be the reason for her menstruation lasting more than ten days?

Dr. Zhao Xiaodong
Menstruation lasting more than ten days in an 11-year-old girl is primarily due to incomplete maturation of the hypothalamic-pituitary-ovarian axis and its neuroendocrine regulatory function. Menstruation is regulated by hormones secreted by the hypothalamus and pituitary gland, which stimulate follicular development and ovulation. The resulting estrogen and progesterone act on the endometrium. In adolescent girls, immature development leads to insufficient hormone secretion, which can impair follicular development, maturation, and ovulation, resulting in menstrual irregularities. Hormonal imbalances during puberty may cause ovulatory dysfunction, clinically manifesting as reduced menstrual flow, prolonged periods, or even anemia. Girls with abnormal menstruation should seek medical evaluation promptly and, under a doctor's guidance, work toward establishing regular menstrual cycles, thereby preventing complications such as infections and anemia caused by menstrual disorders.
