Answer

If a young patient has had irregular menses since menarche, the most common etiology of her bleeding is anovulation.

Anovulatory bleeding is most common in young girls (aged 12-18 y) and common in obese females of any reproductive age.

If a patient's bleeding normally occurs at regular intervals and the irregularity is new in onset, pathology must be ruled out, regardless of age.
