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 28 days, or more than 35 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.
