What are the main symptoms of primary dysmenorrhea?

In medical research, dysmenorrhea can be divided into primary dysmenorrhea and secondary dysmenorrhea. Many people do not know the symptoms of these dysmenorrhea very well. Below, I will first give you a detailed introduction to the symptoms of primary dysmenorrhea.

1. The symptoms of primary dysmenorrhea mostly begin with the onset of menstruation or a few hours before vaginal bleeding, often with spasmodic colic, lasting 1/2 to 2 hours. After the onset of severe abdominal pain, it turns into moderate paroxysmal pain, which lasts about 12 to 24 hours. The menstrual blood flows smoothly, and the symptoms of dysmenorrhea gradually disappear. Occasionally, patients with dysmenorrhea need to stay in bed for 2 to 3 days.

2. Primary dysmenorrhea often disappears on its own after childbirth, or gradually disappears with age after marriage. The causes of primary dysmenorrhea are endometrial cast shedding (membranous dysmenorrhea), uterine hypoplasia, uterine curvature, cervical stenosis, poor posture, physical factors, allergic reaction states and mental factors.

3. Primary pain often occurs during ovulatory menstruation. Therefore, there are usually no symptoms of primary dysmenorrhea or only mild discomfort in the first 1 to 2 years after menarche. Patients with severe dysmenorrhea will experience spasmodic pain. It often occurs in young women 1 to 2 years after menarche. If regular dysmenorrhea occurs at the beginning or spasmodic dysmenorrhea occurs after the age of 25, other abnormal conditions should be considered.

The above is a detailed description of the symptoms of primary dysmenorrhea, which I hope will help you better understand the knowledge of dysmenorrhea. If you have other questions about dysmenorrhea, you can contact our online experts to answer your questions.
