Irregular Menstruation

In normal situations, menstrual periods begin during puberty.  For every girl, puberty will start at different times but typically will begin between the ages of 10 and 16 years old.  Menstrual periods, commonly referred to as a “period,” will continue until a woman transitions through menopause.

All girls are different, thus normal menstrual periods will vary in cycle starting points, duration of the period, and in the intensity of bleeding and cramping.

The average menstrual cycle begins 28 days apart and typically lasts between four and seven days.  Periods that begin between 21 and 35 days apart are considered within a normal range.

Menstrual cycles that begin less than 21 days apart or last longer than 40 days are considered abnormal.  The clinical term for this abnormality is “irregular menstruation.”  In young girls, irregular menstruation may also include heavy bleeding during menstruation.

Young girls who are approaching puberty naturally experience changes in their body’s hormone levels of estrogen and progesterone.  These changes can, however, disrupt the normal menstrual cycle as young women progress through puberty.

Eating disorders that lead to rapid weight gain or loss may also contribute to irregular menstruation.

Diagnosis and Treatment

Treatment for irregular periods during puberty may not be necessary; however, understanding the root of the problem can provide peace of mind when no underlying disease exists.  Even if no underlying disease exists, irregular menstruation can lead to additional problems, like infertility.
