What causes menstrual abdominal pain?

After women's bodies mature, they begin to experience the natural physiological phenomenon of regular menstruation every month. Different women will experience different menstrual symptoms, such as irritability, palpitations, difficulty sleeping, and abdominal pain during menstruation. Abdominal pain during menstruation is also called dysmenorrhea, which is the most common gynecological problem. Let's take a look at the causes of dysmenorrhea.

There are many factors that cause dysmenorrhea, the most common ones are as follows:

(1) Cervical stenosis mainly causes obstruction of menstrual outflow, leading to dysmenorrhea.

(2) Uterine hypoplasia Poor uterine development is prone to abnormal blood supply, causing uterine ischemia and hypoxia, leading to dysmenorrhea.

(3) Abnormal uterine position: If a woman's uterus is extremely retroflexed or anteflexed, it may affect the smooth flow of menstrual blood and cause dysmenorrhea.

(4) Psychological and neurological factors: Some women are overly sensitive to pain.

(5) Genetic factors: Dysmenorrhea in daughters is related to dysmenorrhea in mothers.

(6) Endocrine factors: Menstrual abdominal pain is related to increased progesterone in the luteal phase.

(7) The level of prostaglandins (PG) in the endometrium and menstrual blood increases. Prostaglandin E2 (PGE2) acts on uterine muscle fibers to cause them to contract and cause dysmenorrhea. The prostaglandin content in the endometrial tissue of menstrual patients is significantly increased compared with that of women with normal uterine function.

(8) Excessive contraction of the uterus. Although the uterine contraction pressure of patients with dysmenorrhea is basically the same as that of normal women (normal pressure is about 4.9Kpa), the uterine contraction lasts longer and is often difficult to relax completely, so dysmenorrhea occurs due to excessive uterine contraction.

(9) Abnormal uterine contraction. Patients with dysmenorrhea often have abnormal uterine contractions, which often lead to ischemia of uterine smooth muscles. Uterine muscle ischemia can cause spasmodic contractions of the uterine muscles, resulting in pain and dysmenorrhea.

(10) Gynecological diseases such as endometriosis, pelvic inflammatory disease, adenomyosis, uterine fibroids, etc. Placing an intrauterine contraceptive device (commonly known as an IUD) in the uterus can also easily cause dysmenorrhea.

(11) Dysmenorrhea is caused by psychological stress, long periods of sitting, poor blood circulation, poor menstrual blood flow, and a preference for cold foods during the onset of menstruation in young girls.

(12) Strenuous exercise during menstruation, exposure to wind, cold, dampness, etc. can easily cause dysmenorrhea.

From the above content, it can be seen that dysmenorrhea is not a small problem. There are many pathological reasons that can cause dysmenorrhea. It is recommended that female friends with long-term dysmenorrhea symptoms should check gynecological problems as soon as possible. In addition, it is worth reminding female friends that they must pay attention to keeping warm during menstruation and perform hygienic cleaning every day (only shower, not bath).
