What are the causes of menstrual blood not being expelled?
Generally, the menstrual cycle lasts approximately 28 to 30 days. A period that arrives up to seven days earlier or later than expected is still considered within the normal range. However, if menstruation becomes significantly shorter in duration—or ceases altogether—it may signal perimenopause or amenorrhea. This could indicate an underlying physical issue and serves as a warning sign. So, what causes menstrual blood to fail to discharge?
What Causes Menstrual Blood to Fail to Discharge?
Common causes of absent menstruation (amenorrhea) include stress-induced amenorrhea and amenorrhea resulting from excessive weight loss. In today’s highly competitive society, individuals often experience elevated psychological stress while striving to excel at work. Persistent low mood, depression, or chronic anger can disrupt the function of both the pituitary gland and ovaries, leading to menstrual irregularities—including amenorrhea. Similarly, extreme dieting and rapid weight loss can disturb hormonal balance: consuming only boiled vegetables or fruits while severely restricting dietary fat intake reduces overall body fat, which in turn impairs estrogen production. In severe cases, this may lead to amenorrhea.

Traditional Chinese medicine (TCM) may be used to regulate absent or delayed menstruation. Herbs such as *Leonurus japonicus* (Yi Mu Cao), *Angelica sinensis* (Dang Gui), and *Cimicifuga racemosa* (Black Cohosh) are traditionally believed to promote menstrual flow. Women experiencing delayed periods may consider these herbal remedies—but they must not be used indiscriminately. Patients should first consult a qualified TCM practitioner for a thorough evaluation; only then should treatment be initiated under professional guidance—ensuring greater efficacy and safety.

Patients are advised to maintain regular daily routines, minimize late-night activities, ensure adequate rest and sufficient sleep, and actively practice stress reduction techniques. We hope this information proves helpful.
