What causes red discharge after menstruation when using moxibustion, and what should be done?
Generally, spotting or bleeding after menstruation has ended and following moxibustion may be caused by factors such as incomplete endometrial repair, thermal stimulation from moxibustion, endometritis, uterine fibroids, or cervical polyps. Appropriate measures can be taken based on the specific situation. Detailed analysis is as follows:

1. Incomplete Endometrial Repair
The endometrium may not have fully regenerated immediately after menstruation ends, leaving minor wound surfaces. Discontinue moxibustion temporarily, get adequate rest, avoid strenuous exercise, and frequently change sanitary products to keep the external genital area dry.
2. Thermal Stimulation from Moxibustion
The warming effect of moxibustion accelerates pelvic blood circulation and stimulates uterine contractions, which may expel residual menstrual blood in the uterine cavity. Reduce the duration and frequency of moxibustion sessions, avoid abdominal acupoints, and monitor any bleeding.
3. Endometritis
Bacterial infection causes congestion and swelling of the endometrium. Moxibustion-induced stimulation may exacerbate inflammation and lead to bleeding, often accompanied by a sensation of heaviness or discomfort in the lower abdomen. Under medical guidance, medications such as cefuroxime axetil tablets, levofloxacin capsules, or metronidazole tablets may be prescribed. Avoid sitz baths during treatment.
4. Uterine Fibroids
Fibroids can interfere with normal uterine contractions. After moxibustion, blood vessels near the fibroid may rupture and cause bleeding, possibly accompanied by increased menstrual flow. Follow your doctor’s advice regarding medications such as mifepristone tablets, tranexamic acid tablets, or Guizhi Fuling capsules. In severe cases, surgical removal of fibroids (myomectomy) may be required.
5. Cervical Polyps
Cervical polyps are fragile in texture; pelvic congestion during moxibustion may cause surface blood vessels on the polyp to rupture and bleed, typically resulting in contact bleeding. Medical consultation is recommended for polyp removal surgery. Regular follow-up visits are necessary post-surgery, and sexual intercourse should be avoided until fully healed.
It is advisable to wait 3–5 days after menstruation ends before undergoing moxibustion. Proper preparation and knowledge of acupoints are recommended prior to treatment. Maintain regular daily routines, practice good sexual hygiene, and undergo annual gynecological examinations. If bleeding persists or is accompanied by an unusual odor, seek prompt medical evaluation to identify the underlying cause.
