Menstrual Irregularities in Children

LIke ThisLIke ThisLIke ThisLIke ThisLIke This


One of the most common complaints of adolescent girls is irregular, profuse menstruation, called dysfunction uterine bleeding (DUB).

  • The most common cause for DUB is when a woman's ovaries don't release an egg. Not ovulating causes her period to come later or earlier, and heavier than usual.
  • Young girls commonly experience DUB because their menstrual cycles have not yet settled into a pattern and ovulation isn't occurring.
  • Older adolescents may not ovulate with stress or illness.
