Introduction
Light menstrual flow with dark blood may be due to a relatively small uterine size and reduced endometrial surface area; if the menstrual cycle is regular, this condition is considered normal. It could also be caused by pelvic inflammatory disease, which often leads to cold stagnation and impaired qi circulation, resulting in poor blood flow and accumulation of stagnant blood within the uterus. If cervical inflammation is present, inflammatory irritation of the cervix may produce abnormal secretions that, when expelled during menstruation, can lead to reduced menstrual flow with dark-colored blood.
Menstrual blood that is scanty and dark in color may be caused by physiological factors, or it could result from pathological conditions such as pelvic inflammatory disease or endometritis. A detailed analysis is as follows:
I. Physiological Factors
If the uterus is relatively small with a smaller endometrial surface area, and the menstrual cycle is regular, having light and dark-colored menstrual flow is considered normal and does not require excessive concern.
II. Pathological Factors
1. Pelvic Inflammatory Disease (PID)
PID may result from pathogen infection or unhygienic sexual practices. It often leads to cold stagnation and impaired qi circulation, causing poor blood flow and accumulation of stagnant blood within the uterus. Treatment may include medications such as Bazhen Yimu Capsules, Bu Xue Granules, or Buzhong Yiqi Pills, taken under medical guidance.
2. Cervicitis
If cervicitis is present, inflammation may irritate the cervix, leading to abnormal secretions. When these mix with menstrual blood, it can result in scanty, dark-colored menstruation. Treatment options may include Azithromycin Dispersible Tablets, Doxycycline Tablets, or Metronidazole Tablets, used under a physician's supervision.
In addition, endometritis could also be a possible cause. Patients are advised to seek timely medical evaluation at a hospital to determine the exact cause and receive appropriate treatment.
