Depression increases risk of menstrual pain

Women are twice as likely as men to suffer from depression and often experience more severe physical symptoms. This gender difference is particularly evident during reproductive years and dramatically impacts the lives of hundreds of millions of people worldwide. However, although links between mental health and reproductive health have been found, the associations have remained underexplored.

Our findings provide preliminary evidence that depression may be a cause, rather than a consequence, of dysmenorrhea as we did not find evidence that period pain increased the risk of depression."We used a specialised technique called Mendelian randomisation to analyse genetic variation and identify specific genes that may mediate the effect of depression on menstrual pain.

The team analysed approximately 600,000 cases from European populations and 8,000 from East Asian populations and saw a strong link in both datasets. They also investigated the possibility that sleeplessness, often experienced by those suffering from depression, was a significant mediator between depression and dysmenorrhea.

"We found that increased sleep disturbances could exacerbate menstrual pain. Addressing sleep issues may therefore be crucial in managing both conditions. However, more research is required to understand the intricate links between these factors," says Liu.

Holistic approach

This study further highlights the need for a holistic approach when treating mental health and reproductive issues.

Liu says: "Mental disorders are often not considered when treating conditions such as period pain. Our findings emphasize the importance of mental health screening for people who suffer from severe menstrual pain. We hope this can lead to more personalised treatment options, and improved healthcare, and reduce the stigma surrounding the conditions.

"Our results provide evidence of a link between our neurological systems and the rest of the body. By exploring and understanding these relationships better, we can make a real difference to the millions of people experiencing period pain and mental health issues."
