The main reasons for short menstrual periods

Nowadays, women have some problems with their menstruation. Irregular menstruation is very common in hospitals. However, many women think that irregular menstruation is very common. They don’t pay attention to such problems when they occur, and don’t go for examination and treatment. Sometimes it causes some unnecessary trouble, especially short menstrual period, which should attract our attention. Let’s take a look at the reasons below.

In fact, reduced menstrual volume and shorter menstrual periods are symptoms of scanty menstruation. The main reasons for scanty menstruation are as follows:

1. Exposure to cold during menstruation: Because women are exposed to cold stimulation during menstruation, the blood vessels in the pelvic cavity will contract excessively, resulting in less menstrual volume or even amenorrhea.

2. Excessive dieting: Excessive dieting will lead to insufficient nutrition supply. If the nutrients absorbed are not enough to meet the body's needs, the body will produce a defensive reaction, which may also cause too little menstrual blood volume or even amenorrhea.

3. Sulking or encountering major spiritual stimulation and psychological trauma can also easily lead to scanty menstruation in girls.

4. Causes due to the endometrium itself: such as adhesion of the cervical canal, which makes it difficult for menstrual blood to be discharged. These patients often have cyclical abdominal pain once a month. For example, if there is uterine adhesion, the symptoms will vary depending on the degree. A large adhesion range may cause amenorrhea, while a small adhesion range may cause reduced menstruation.

5. Endocrine reasons: such as abnormal secretion of various hormones or anovulation.

【Diagnosis points 】

1. The menstrual cycle is basically normal, but the menstrual volume is significantly reduced, or even stops with a few drops. This is the key point for the diagnosis of this disease, and it is often seen in the late menstruation period.

2. Some drugs can cause oligomenorrhea, such as contraceptives, antipsychotic drugs, anti-tumor drugs, and drugs for the treatment of endometriosis (such as tamoxifen, danazol, and nemethicone). In addition, drugs such as tripterygium wilfordii tablets and bromocriptine can also cause oligomenorrhea. During clinical consultation, detailed medical history should be inquired.

3. Multiple abortions or rough operations that damage the basal endometrium of the uterus or uterine adhesions can cause oligomenorrhea, so it is also necessary to inquire about the abortion surgery. Postpartum hemorrhage sometimes first manifests as oligomenorrhea, followed by amenorrhea.

4. Simple oligomenorrhea in anovulatory functional uterine bleeding is relatively rare and is sometimes a precursor to anovulatory amenorrhea. Polycystic ovary syndrome can also be seen in oligomenorrhea, often accompanied by late menstruation, weight gain, and then amenorrhea. Patients with premature ovarian failure also first experience oligomenorrhea and then amenorrhea.

5. For patients with scanty menstruation and late menstruation, miscarriage or ectopic pregnancy should be ruled out first. Urine, blood pregnancy tests and B-ultrasound can be used for identification.

If you, a female friend, have a short menstrual period, you must take it seriously, especially if you have not given birth. You should go to the hospital for a check-up, as this will affect future pregnancy. Women with short menstrual periods and small amounts of menstrual flow have a lower chance of getting pregnant than normal women.
