Painful Menstruation in The Young Female
Menstrual cramps are the leading cause of absenteeism in young females. About one-half of young females experience some degree of menstrual pain. Incidence of painful menstruation increases with one's gynaecological age.
Adolescent girls typically develop painful menstruation, 1-2 years after menarche (first menstrual bleed). This is because primary dysmenorrhea occurs with ovulation. Ovulatory menstrual cycles begin 1-2 years after menarche.
With the increase in Prostaglandins levels in the endometrium (inner lining of the wall of the womb) the uterine muscles contract more strongly, decreasing uterine blood flow and thus, causing pain. Systemic symptoms are also due to prostaglandins.
- Females who have never been pregnant
- Females who smoke cigarette
- Females with heavy menstrual bleed
SYMPTOMS OF PRIMARY DYSMENORRHEA(Prostaglandins)
- Lower abdominal cramps
- Nausea, Vomiting and Diarrhea
- Low back and Upper thigh pain
- Urinary frequency
- Headaches, Nervousness, Sweating
TREATMENT OF PRIMARY DYSMENORRHEA
2 available methods of controlling primary dysmenorrhea:
- Block prostaglandins production, or
- Block ovulation
The uterine pain can be reduced with prostaglandin synthase inhibitors like Ibuprofen, naproxen and other NSAIDs.
NSAIDs (examples: Ibuprofen, Naproxen) are the preferred pain medication for painful menstruation
- Ibuprofen 200-600mg every 6-8 hours
- Naproxen 275mg every 6-8hours
These medications are most effective when started at the first sign of menstrual flow.
Oral Contraceptive Pills (OCP)
25% of painful menstruations may not improve with NSAIDs. A trial of Oral Contraceptive Pills may be used to suppress ovulation. It may take 2-3 cycles before OCP work effectively to reduce menstrual pain. OCP Block ovulation
DEPO-PROVERA (Depot medroxyprogesterone acetate) can be given intramuscularly, every 90 days, to block ovulation.
Painful menstruation is related to a pathology in the pelvis. Once the underlying condition is treated, the menstrual pain usually goes away.
Secondary Amenorrhea usually starts after 20 years of age
The pain is not crampy, the pain is dull and constant
Common causes include:
- Pelvic infections
- Uterine outflow obstruction
Functional endometrium (tissue that normally lines the inside of the uterus) gets seeded and grows outside of the uterus, and may be found on the surfaces of other organs in the pelvis, the intestines, and very rarely, on the skin
The young woman may present with painful menstruation, that does not respond to NSAIDs and OCP.
The Pain is not cyclic and menstrual bleed may be irregular. There may be associated abdominal discomfort, bloating, Painful intercourse and tenesmus (inclination to empty the bowels) and anal pain.
Pelvic infections may lead to acute painful menstruation.
Signs of infection, such as Fever, chills, bodily aches are present at the time of menstrual flow.
Women often develop chronic pelvic pain, as a consequence of pelvic inflammatory diseases.
Physicians treat Pelvic infections with Antibiotic. Adequate treatment may require hospital admission for the teenager
Teenagers with history of surgery, including, abortions, may have outflow tract obstruction. Fibroids are rare in women under 20 years, however, if the bleeding is heavy, prolonged or associated with passage of clots, fibroids may be more likely.
Those with Secondary dysmenorrhea need to see a physician. An ultrasound of the uterus may be done to look for abnormalities of the womb.
Endometriosis is usually confirmed with a Laparoscopy
