What causes a sudden shortening of the menstrual period?

Menstruation is something that every mature woman experiences every month, except during pregnancy. Whether menstruation is normal or not is directly related to the health of women’s reproductive system. It is no exaggeration to say that menstruation is the indicator of whether every woman’s reproductive function is healthy. It is not good if the menstrual cycle is too long or too short, or if the menstrual flow is too much or too little. So what is the reason for the sudden shortening of menstrual period? Let’s take a look.

1. Caused by neuroendocrine dysfunction: mainly due to unstable or defective function of the lower hindbrain-stomach-ovary axis, that is, menstrual disease.

2. Caused by organic diseases or drugs, including local inflammation, tumors and developmental abnormalities, malnutrition of reproductive organs; intracranial diseases; other endocrine dysfunctions such as thyroid and adrenal cortex dysfunction, diabetes, Sheehan's disease, liver diseases; blood diseases, etc. Menstrual irregularities may occur in women who use drugs to treat mental illnesses, endocrine preparations, or intrauterine devices for contraception. Certain occupations, such as long-distance runners, are prone to amenorrhea. In addition, some abnormal bleeding during pregnancy is often mistaken for menstrual irregularities. >> Women should remember to take care of their menstrual cycle when losing weight after childbirth

The normal menstrual cycle of women is generally 28-30 days. The length of the cycle varies from person to person, but a menstrual cycle shorter than 21 days should be considered an abnormal short menstrual cycle.

The main reasons for short menstrual cycles in adult women are as follows:

1. Ovarian dysfunction and menopausal dysfunctional uterine bleeding are both causes of short menstrual cycles.

2. People with luteal insufficiency have a shorter menstrual cycle due to the shortening of the relatively fixed luteal phase.

3. Some patients with uterine fibroids have frequent menstruation, and their menstrual cycle becomes shorter due to frequent menstruation.

4. Some women who experience heavy bleeding during ovulation may also experience frequent menstruation, which is also one of the reasons for a short menstrual cycle.

The above introduces in detail several main reasons for the sudden shortening of menstrual period. I hope it can serve as a good reference for more female friends. The health of the female reproductive system requires our special care. Even our usual emotions and daily diet may affect our menstrual cycle and menstrual volume, so female friends should pay more attention.
