How to Assess Menstrual Flow Based on Sanitary Pads

Women are generally familiar with menstruation, which begins at a certain age. During menstruation, many physical discomforts may arise. It is important to address these promptly and perform appropriate beauty and detoxification routines; otherwise, they may adversely affect overall health. If menstrual flow is abnormal, the underlying cause should be identified and addressed promptly. So, how can one assess menstrual volume by observing sanitary pads?

How to Assess Menstrual Volume Using Sanitary Pads

During menstruation, the amount of blood on a sanitary pad can be estimated visually. A small amount of red staining indicates light menstrual flow. Brown or dark brown staining also suggests relatively scant flow. If blood has soaked through approximately half of the pad’s surface, this reflects a moderate flow. If the entire pad is saturated, the flow is considered heavy. The typical menstrual period lasts seven days: flow is usually lightest on Day 1; increases gradually from moderate to heavier between Days 2–4; begins decreasing after Day 4; and becomes progressively lighter and clearer by Days 6–7.

It is recommended to consume light, nutritionally balanced, and varied foods during menstruation—especially those rich in high-quality protein, minerals, vitamins, and dietary fiber. Sexual intercourse should be avoided during menstruation, as should bathing (e.g., soaking in bathtubs) and swimming, since these activities may increase the risk of pathogenic microbial invasion and subsequent infections. Therefore, maintaining proper menstrual hygiene, adjusting dietary intake appropriately, and ensuring adequate sleep constitute the most fundamental requirements for sustaining good health.

In daily life, maintain regular eating habits—avoid spicy, stimulating, or overly greasy foods, refrain from binge eating, and avoid staying up late. We hope this information proves helpful.
