Clinical manifestations of dysmenorrhea in children

Dysmenorrhea in children can be divided into primary dysmenorrhea and secondary dysmenorrhea. Primary dysmenorrhea in children is caused by the uterus itself and is not accompanied by pelvic lesions. It is common during the ovulatory menstrual period, so about 75% of cases occur within 6 to 12 months of menarche. If ovulation occurs at the time of menarche, dysmenorrhea will begin at the time of menarche; 13% of cases begin to experience dysmenorrhea in the second year after menarche, 5% in the third year, and only 4% in the fourth year. Secondary dysmenorrhea is rare in adolescent girls and is caused by pelvic diseases such as endometriosis, chronic pelvic inflammatory disease, and pelvic congestion.

Clinical manifestations of dysmenorrhea in children

Primary dysmenorrhea in children: 1. Girls who have menarche for 1 to 3 years (about 14 to 15 years old) will experience spasmodic pain in the middle of the lower abdomen about 12 hours before menstruation or during menstruation. In severe cases, it may spread to the lumbar sacral region and abdomen, accompanied by nausea, vomiting, headache, fatigue and other symptoms. In severe cases, the face will turn pale, the limbs will become cold, and there may even be collapse. The pain will last for 1 to 4 days. 2. No symptoms during the non-menstrual period. 3. Digital rectal examination and pelvic B-ultrasound examination are normal.

Secondary dysmenorrhea in children: Secondary dysmenorrhea in children is different from primary dysmenorrhea. The abdominal pain occurs several years after menstruation and is more common in adult women. The pain is characterized by aggravation during menstruation and discomfort even during non-menstrual periods. Non-morphine analgesics are ineffective. Pelvic examination and pelvic B-ultrasound examination can reveal lesions.
