What Causes Menstruation to Be Absent?

During this period, menstrual flow has been extremely light following menstruation onset. You feel that menstrual blood is unable to exit the uterine cavity normally, and you also experience abdominal discomfort. So, what causes menstrual blood to fail to discharge?

What Causes Menstrual Blood to Fail to Discharge?

Failure of menstrual blood to discharge may result from intrauterine obstruction preventing its smooth expulsion. Additionally, Traditional Chinese Medicine (TCM) attributes this condition to insufficient menstrual blood volume—namely, deficiency of the “Sea of Blood” (Xue Hai), which leads to stagnation and lack of flow. Polycystic ovary syndrome (PCOS) commonly disrupts endocrine function, manifesting primarily as oligomenorrhea (infrequent menstruation) and oligo-ovulation (infrequent ovulation), often accompanied by obesity, acne, and acanthosis nigricans—all of which may contribute to amenorrhea. Hyperprolactinemia (elevated prolactin levels), excessive weight loss, or extreme dieting may also cause amenorrhea or oligomenorrhea, with menstrual cycles occurring only every two to three months.

If blood stasis is present, treatment options include Guizhi Fuling Wan (Cinnamon Twig and Poria Pill), Yimucao Granules (Motherwort Granules), or Wuji Baifeng Wan (Black-Boned Silky Chicken and White Phoenix Pill). Under medical supervision, prescriptions such as Tao Hong Si Wu Tang (Peach Kernel and Safflower Four-Ingredient Decoction) or Shaofu Zhu Yu Granules (Lower Abdomen Stasis-Resolving Granules) may also be used to promote blood circulation and resolve stasis, thereby alleviating symptoms. For abnormal menstrual bleeding volume, color Doppler ultrasound examination is recommended to assess the uterus and adnexa for any masses, followed by targeted treatment based on findings.

In daily life, maintain regular meals and consume nutrient-rich foods—including meat, eggs, dairy products, and fresh vegetables and fruits—to meet your body’s nutritional needs. Additionally, strive to maintain emotional well-being and avoid vigorous physical activity during menstruation. We hope this information proves helpful to you!
