How many women are affected by menstrual irregularities?

Menstrual irregularities occur in an estimated 14% to 25% of women of childbearing age.1

Estimates of the number of women with menstrual irregularities may differ by the cause or nature of the irregularity. For example, if a woman experiences severe cramps, she might be included in the tally of women with endometriosis rather than in the tally of women with menstrual irregularities.
