What causes dysmenorrhea?

Menstruation is a normal physiological phenomenon for women. However, most women will experience discomfort during menstruation, but some women will experience dysmenorrhea. Some dysmenorrhea is more severe and has a great impact on daily life. Generally speaking, if dysmenorrhea is more severe, it is best to stay in bed to avoid causing more serious harm. What causes dysmenorrhea?

What causes dysmenorrhea?

1. Primary

Half of all women experience dysmenorrhea, but most of them are primary, probably

50%, this is a physiological one. Some discomforts during menstruation, such as lower abdominal pain, are normal physiological phenomena. Everyone will feel some discomfort during menstruation, but everyone feels differently. In other words, dysmenorrhea is a disease only when it affects normal life.

2. Uterine hypoplasia

Poor uterine development can easily lead to abnormal blood supply, causing uterine ischemia and hypoxia, leading to dysmenorrhea.

3. Weakness

The upper abdominal muscles support the abdominal organs. If these muscles are not fully developed, their ability to support the organs will be poor, causing pain due to the weight of the organs.

4. Mental stress

When menstruation comes, I feel irritable, anxious, nervous and fearful, so I am more sensitive to pain than ordinary people. Even the slightest discomfort can cause pain, and the more nervous you are, the more pain you feel. This pain is mainly caused or aggravated by psychological factors.

5. Endometriosis

It has symptoms very similar to those of primary dysmenorrhea.

If the patient has progressive dysmenorrhea or a family history of endometriosis (either the mother or a sister has the disease), laparoscopy should be performed early to confirm the diagnosis and conservative surgical treatment should be performed early to preserve fertility.

6. Hormone influence

Menstruation usually occurs about two weeks after ovulation. After ovulation, a corpus luteum is gradually produced, which can secrete progesterone. Excessive production of progesterone can cause the cervix to contract strongly, affecting the outflow of menstrual blood from the uterus. Excess menstrual blood in the uterus will stimulate the uterus and cause it to contract strongly, thus causing pain.

7. Cervical stenosis

The main problem is that menstrual outflow is blocked, causing dysmenorrhea.

8. Increased levels of prostaglandins (PG) in the endometrium and menstrual blood

Prostaglandin E2 (PGE2) acts on uterine muscle fibers to cause them to contract and cause dysmenorrhea. The prostaglandin content in the endometrial tissue of patients with dysmenorrhea is significantly higher than that of women with normal endometrium.

9. 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.

10. 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.

11. Excessive exercise

Vigorous exercise, exposure to wind, cold, dampness and cold, etc. can easily cause dysmenorrhea.

12. 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.
