Menstrual Irregularities | Symptoms & Causes
What are the symptoms of menstrual irregularities?
If your daughter has dysfunctional uterine bleeding, she may notice:
- bleeding or spotting from the vagina occurs between periods
- menstrual periods may be less than 21 days or more than 45 days apart
- the time between each cycle changes each time
- the need to change her pad or tampon during the night or every few hours
- bleeding that lasts for more than seven days
What causes menstrual irregularities?
Conditions that cause a lack of ovulation could be the culprit of menstrual irregularities or dysfunctional uterine bleeding. Common causes include:
- eating disorders
- weight changes
- athletic competition
- chronic illnesses
- drug abuse
- endocrine disorders
- polycystic ovary syndrome (PCOS)
If your daughter has a vertical or complete vaginal septum, she has two openings to her vagina, and this may prevent one tampon from stopping the flow of blood.
Menstrual Irregularities | Diagnosis & Treatments
How are menstrual irregularities diagnosed?
If your daughter is experiencing irregular and profuse menstrual bleeding, her physician will perform a thorough history. A pelvic examination may be performed to rule out the possibility of pregnancy disorders or pelvic infections, if applicable. In cases of excessive bleeding, a Hematocrit blood test will determine the amount of blood loss.
How are menstrual irregularities treated?
During the first few years of a girl's menstrual cycle, she may not benefit from treatment unless heavy blood loss causes anemia. A physician may recommend an iron supplement for the anemia.
Oral birth control pills or other hormonal treatments are often used to regulate or temporarily stop the menstrual cycle.
