Is Menstrual Delay Due to Qi Deficiency or Blood Deficiency?

Many women likely experience menstrual irregularities, one of which is delayed menstruation. Women are accustomed to having their period every month, so missing a period entirely in a given month naturally raises concern and prompts daily reflection. So, is delayed menstruation caused by qi deficiency or blood deficiency?

Is Delayed Menstruation Due to Qi Deficiency or Blood Deficiency?

Delayed menstruation can result from either qi deficiency or blood deficiency. When qi is deficient, the body’s ability to propel blood circulation weakens, leading to sluggish flow of qi and blood—and consequently, delayed menstruation. Blood deficiency, on the other hand, results in insufficient blood supply for menstruation, preventing normal menstrual discharge. Qi deficiency may also be accompanied by symptoms such as shortness of breath, fatigue, and low mood. Under a physician’s guidance, herbal formulas such as Shen Ling Bai Zhu Wan (Ginseng and Polyporus Powder) or Xiang Sha Liu Jun Zi Wan (Costus Root and Sand仁 Six Gentlemen Pills) may be used for treatment.

Menstrual delay may stem from various causes, including pregnancy, medication effects, endocrine disorders, chronic illness, or psychological factors. If diagnostic evaluation reveals that delayed menstruation is due to diminished ovarian function, drospirenone–ethinyl estradiol tablets may be prescribed for regulation. For patients with premature ovarian insufficiency (POI)-induced menstrual delay, long-term treatment with estradiol valerate and cyproterone acetate tablets is typically required. If menstruation is delayed by more than 10 days, a color Doppler ultrasound examination at a hospital is recommended.

Women should avoid excessive physical exertion before and after menstruation to prevent damage to the reproductive organs—including potential structural injury. We hope this information proves helpful to you.
