What does it mean if menstruation is absent for one month?

Missed menstruation for one month may result from excessive dieting and weight loss, chronic mental anxiety, polycystic ovary syndrome (PCOS), intrauterine adhesions, or ovarian dysfunction. It can be improved through dietary adjustments, emotional relaxation, and menstrual-regulating medications; however, amenorrhea lasting two consecutive months warrants prompt medical evaluation.

1. Excessive dieting and weight loss: Prolonged inadequate caloric intake disrupts hormonal secretion, preventing normal endometrial thickening and shedding—resulting in amenorrhea without significant abdominal pain. It is recommended to resume balanced, three-meal-a-day nutrition, increase intake of protein- and iron-rich foods, and discontinue extreme fat-loss regimens.

2. Chronic mental anxiety: Persistent sleep deprivation and excessive stress impair hypothalamic regulatory function, leading to disordered hormonal rhythms and delayed menstruation—often accompanied by dizziness and fatigue. It is advised to ensure adequate daily sleep and alleviate negative emotions through activities such as walking and meditation.

3. Polycystic ovary syndrome (PCOS): Endocrine and metabolic imbalances inhibit normal follicular development, significantly delaying the menstrual cycle and frequently presenting with acne and hirsutism. Under physician guidance, medications such as ethinylestradiol–cyproterone acetate tablets, progesterone soft capsules, and Dingkun Dan may be used to alleviate symptoms.

4. Intrauterine adhesions: Repeated intrauterine procedures may damage endometrial tissue, causing adhesions and cavity obstruction—preventing normal menstrual outflow and occasionally resulting in mild lower abdominal heaviness or discomfort. Under medical supervision, medications such as estradiol valerate tablets, Kuntai capsules, and Yimucao granules may help relieve symptoms.

5. Ovarian dysfunction: Hormonal fluctuations disrupt ovarian ovulation timing, leading to menstrual cycle irregularity and delay—commonly associated with lumbosacral and knee weakness and reduced menstrual flow. Under physician guidance, medications such as dydrogesterone tablets, Wuji Baifeng Wan, and Xiaoyao Wan may be prescribed to improve symptoms.

For daily self-care, maintain abdominal warmth, limit cold or raw foods and icy beverages, adhere to regular sleep-wake schedules to minimize late-night activity, and engage moderately in gentle physical activities such as jogging or yoga to stabilize endocrine function.
