The menstrual interval is calculated as the number of days between the first day of two consecutive menstrual cycles. Typically, women's menstrual intervals range from 28 to 30 days. It is considered normal if the cycle is advanced or delayed by 3 to 7 days. Menstruation usually lasts for three to seven days. During menstruation, it is important to avoid excessive fatigue, take adequate rest, and avoid spicy, raw, and cold foods in your diet.
The menstrual cycle is calculated as the number of days between the first day of two consecutive menstrual cycles, typically ranging from 28 to 30 days. A cycle that is advanced or delayed by 3 to 7 days is still considered normal. The duration of menstruation is generally 3 to 7 days, and the amount of blood loss during a menstrual cycle is approximately 30 to 80 milliliters, with the second and third days being the heaviest.
1. Rest adequately, avoid excessive fatigue, and protect yourself from cold.
2. Avoid spicy, stimulating, raw, and cold foods.
3. Abstain from sexual activity during menstruation to prevent gynecological infections.
4. Observe the amount and duration of menstruation.
If menstrual flow is excessive and lasts for a prolonged period, it could indicate pathological changes in the endometrium, such as endometrial hyperplasia or intrauterine lesions. If the flow is particularly heavy and lasts for a long time, it is recommended to consult a doctor and undergo pelvic ultrasound for initial diagnosis. If necessary, hysteroscopy or uterine fractional curettage may be performed.
