Is it normal to have a period for a day and a half?

Menstruation is a physiological phenomenon unique to the female body and is common to many women. Moreover, menstruation is an important physiological characteristic that distinguishes women from men. However, for women with normal menstruation, their menstrual cycle is fixed and is generally around 3-7 days. New women find that their menstruation only lasts for a day and a half. Is this normal?

How many days does the menstrual period usually last?

Menstrual period (also called menstrual period). A woman's menstrual period lasts about 3-5 days, and 2-8 days is not uncommon. The general pattern of menstruation is that there is not much menstrual blood on the first day, but it increases on the second and third days, and then gradually decreases until the menstrual blood stops. This is because the endometrium just begins to shed on the first day, and on the second and third days the shedding of the endometrium increases, the amount of bleeding also increases, the uterus is stimulated, the contraction increases, and a large amount of menstrual blood is discharged. For some people, after their menstrual blood has stopped, it comes back a day or two later, which is called "menstrual bleeding returning". This is not a disease but a normal phenomenon. However, some women's menstrual period lasts for 10 days or even 20 days, and their menstrual period is endless; some women's menstrual period is very short and it just passes in a flash. Both phenomena are abnormal. High pressure from work and study, irregular lifestyle, abortion, and taking birth control pills can all lead to disharmony of Qi and blood, causing endocrine disorders and menstrual cycle disorders. Irregular menstruation is considered an endocrine disorder by Western medicine.

Why is a woman's menstrual period short?

A woman's menstruation usually lasts 2-7 days. If the menstruation lasts less than 2 days, it is considered to be a shortened menstrual period. What are the reasons for women's short menstrual period?

1. Uterine hypoplasia: Uterine hypoplasia may manifest as amenorrhea, oligomenorrhea, short menstruation or dysmenorrhea. The most common type of uterine hypoplasia is an immature uterus.

2. Endocrine abnormalities: The endocrine system regulates menstruation. If the estrogen or progesterone levels are too low, symptoms such as short menstruation and too little menstrual flow may occur.

3. Anovulatory menstruation: Anovulatory menstruation often leads to irregular uterine bleeding, which is more common in puberty and menopause. Anovulatory menstruation can be manifested as short menstrual duration and light bleeding.

4. Endometrial tuberculosis: Endometrial tuberculosis often involves the uterus and causes infertility. Therefore, the most common symptom is infertility, followed by pelvic pain and menstrual disorders, which may be accompanied by amenorrhea, oligomenorrhea, and functional uterine bleeding.

5. Abortion and curettage: The cervical endometrium is damaged during abortion and curettage, and adhesions may occur after the operation, such as cervical canal adhesions. A large adhesion range can cause amenorrhea, while a small adhesion range can cause reduced menstruation and shortened menstrual duration.
