Patient's question:
My menstrual cycle is only 21 days each month. Is this normal?Doctor's answer:
The menstrual cycle of women is generally 28 to 30 days. It is still within the normal range if it is advanced or delayed by about 7 days, as the length of the cycle varies from person to person. However, if menstruation does not arrive after more than 7 days, it is considered delayed menstruation. Whether menstruation is normal can, to some extent, genuinely reflect a woman's health. However, menstrual irregularities and delays are relatively common. Although menstrual irregularities and delays can help slow down aging, we should still be particularly vigilant about this phenomenon. However, the reasons for menstrual irregularities and delays can vary greatly depending on the age of the woman.Girls during puberty: The most common reason for delayed menstruation is anovulatory menstrual irregularities caused by the underdeveloped regulatory function of the hypothalamic-pituitary-ovarian axis. Its characteristics include infrequent menstruation, sudden irregular excessive bleeding after a short period of amenorrhea, and prolonged menstrual periods. As age increases and the gonadal axis matures, symptoms gradually subside. However, those with severe symptoms still require treatment.
