# Does psychological stress cause irregular periods?

Yes. A review of 41 studies found that psychological stress is associated with irregular periods and abnormal menstrual flow in otherwise healthy women. Stress is a modifiable risk factor, meaning reducing stress may help.

Healthy adults (with a focus on women)

## What they did

Systematic review of 41 studies on psychological stress and menstrual irregularity in healthy adults. Two independent reviewers screened studies, extracted data, and assessed quality. Stressors included COVID-19 pandemic stress, academic stress, and occupational stress.

## What they found

Most studies reported an association between psychological stress and menstrual dysfunction. The most common disruptions were irregular menstruation and abnormal menstrual flow. However, studies used different definitions of menstrual disorders, making comparison difficult.

## What it means for you

Stress affects menstrual regularity. Because stress is modifiable, managing stress is a potential way to improve menstrual health. The lack of consistent definitions across studies is a limitation.
