Irregular Periods

Also called:Irregular periodsIrregular menstruationUnpredictable cycles

From the TCM perspective: TCM 'yue jing bu tiao'; located in Chong-Ren and uterus, related to liver, spleen and kidney.

Overview

Irregular periods are abnormalities of cycle timing, duration, amount or color of menstruation. TCM sees menstruation as governed by blood through the kidney essence-Tiangui-Chong/Ren-uterus axis and the liver-spleen, with patterns of liver qi stagnation, cold congealing stasis, qi-blood deficiency, and blood heat/yin deficiency.

☯Common patterns (syndrome differentiation)

Liver qi stagnation

Key distinguishing signs: Erratic cycle timing with impeded flow, distending pain in ribs/breasts, low mood or irritability, sighing, thin coat, wiry pulse.
Treatment principle: Soothe liver, regulate qi and menstruation

Cold congealing blood stasis

Key distinguishing signs: Delayed scant dark clotted periods, cold lower-abdominal pain, cold limbs, dark tongue with white coat, deep tight pulse.
Treatment principle: Warm channels, dispel cold and quicken blood

Dual qi-blood deficiency

Key distinguishing signs: Often delayed, scant pale thin flow, pale lusterless face, fatigue, dizziness, palpitations, pale tongue, fine weak pulse.
Treatment principle: Tonify qi-blood and regulate menstruation

Blood heat / yin deficiency

Key distinguishing signs: Early, heavy, dark-red thick flow, vexation, dry mouth, red face or heat in palms/soles, night sweats, red tongue with yellow or scant coat, rapid pulse.
Treatment principle: Clear heat and cool blood, or nourish yin and clear heat

Daily self-care

Track at least three cycles' dates, flow amount, clots and symptoms; keep regular sleep and a healthy weight.
Avoid crash dieting, extreme weight loss and chronic stress; exercise moderately and don't smoke.
Persistent irregularity warrants gynecologic assessment; do not self-use long-term period-regulating herbs or hormones.

When to seek medical help

The following warning signs require prompt medical evaluation — do not rely on self-treatment:

Very heavy bleeding (soaking a pad in 1–2 hours) or bleeding with dizziness/fainting: urgent care.
Postmenopausal bleeding, postcoital bleeding, or pain/bleeding after periods stop: prompt examination.
A delayed period with abdominal pain or bleeding: rule out ectopic pregnancy.
