“Auntie” generally refers to female menstruation. 19 years old without menarche is an abnormal phenomenon.
Menarche refers to the first menstrual period of a woman, which is a cycle of vaginal bleeding under the influence of ovarian hormones, and is an event that normal women go through when they enter puberty. Normally, menarche occurs between the ages of 13 and 14, but can occur as early as 11 or as late as 16.
The absence of menstruation after the age of 16 years should be taken seriously as it may be due to developmental delay, abnormalities in the functioning of the hypothalamic-pituitary-ovarian axis, etc., and is considered an abnormal phenomenon.
It is recommended that patients who have not menstruated at the age of 19 should go to the hospital in time, complete the relevant examinations, clarify the cause of the disease under the guidance of the doctor, and carry out targeted treatment to avoid delaying the condition.
