What foods can help increase menstrual flow?

“Scanty menstruation” refers to a condition in which the menstrual cycle remains regular, but the volume of menstrual flow is significantly reduced—less than 5 mL per period—or the period lasts only two days, or even ends after just a few drops of bleeding. Emotional disturbances, restrictive dieting, medications, and uterine pathology are all potential causes of scanty menstruation. So, what foods can help increase menstrual blood volume? Below, we address this question.

What to Eat to Increase Menstrual Blood Volume

Generally speaking, individuals experiencing scanty menstruation should consume more foods rich in vitamins C and E to promote healthy pelvic circulation. Additionally, drinking a cup of brown sugar water daily during menstruation is recommended. Brown sugar water helps warm the uterus and ovaries and replenishes Qi and blood, thereby regulating menstruation and effectively alleviating scanty menstrual flow. Furthermore, incorporating foods that tonify Qi and nourish blood can enhance overall nutritional intake. If symptoms persist despite dietary adjustments and lifestyle modifications, serum sex hormone panel testing (six hormone assays) should be performed; treatment should then be tailored based on whether test results indicate abnormalities. Patients should also prioritize staying warm, avoid staying up late—especially during menstruation—and maintain balanced physical activity and rest. Emotional well-being is equally important: stress and emotional suppression should be actively relieved—for example, through warm compresses—and maintaining a cheerful mood while avoiding mental or emotional strain is essential. Sexual intercourse must be strictly avoided during this time.

Knowledge Extension: Causes of Scanty Menstruation

1. Chronic Depression

Prolonged depression, psychological trauma, or excessive emotional stress may disrupt the hypothalamic-pituitary-ovarian (HPO) axis, leading to endocrine dysfunction—which in turn contributes to scanty menstruation. Moreover, endometrial tuberculosis not only reduces menstrual flow but may also cause infertility and lower abdominal heaviness or pain. In addition to tuberculosis, direct endometrial injury—such as from repeated induced abortions or multiple curettages—can damage the endometrium and result in decreased menstrual volume.

2. Gynecological Disorders

Polycystic ovary syndrome (PCOS) is an endocrine disorder commonly associated with hormonal imbalances. When estrogen levels are chronically low, the endometrium fails to proliferate adequately, resulting in endometrial thinning and consequently reduced menstrual flow. Hyperprolactinemia is another condition that can cause scanty menstruation and may also lead to amenorrhea. It is characterized by elevated prolactin levels and presents clinically with amenorrhea, galactorrhea, anovulation, and infertility—often triggered by internal or external environmental factors.

The above outlines dietary and lifestyle strategies to help increase menstrual blood volume in cases of scanty menstruation. We hope this information proves helpful.
