What are the reasons for a small menstrual flow?

Patient's question:

Menstrual volume is low, gave birth to two children, 28 years old, using an IUD for over two years, Maternal and Child Health Hospital

Doctor's answer:

Irregular menstruation has many causes, which are typically divided into two major categories in clinical practice: one is functional, such as irregular menstruation caused by endocrine dysfunction; the other is organic, such as conditions like pelvic inflammatory disease, endometritis, and endometriosis, which can also lead to irregular menstruation.
Go to the hospital for a check-up and take medication accordingly. In your daily diet, eat more foods that boost qi and blood, or use traditional Chinese medicine for regulating menstruation, such as angelica sinensis (Danggui), astragalus (Huangqi), and motherwort (Yimucao). Drink plenty of water, reduce spicy and irritating foods, pay attention to a balanced diet, and exercise more.
Wishing you good health.
