Recent research has indicated that long COVID may have a significant impact on menstrual cycles, potentially causing periods to become longer and heavier. This finding emerges nearly five years after the onset of the SARS-CoV-2 virus, as the medical community continues to unravel the complexities associated with long COVID.
A study led by Dr. Jacqueline Maybin at the University of Edinburgh surveyed over 12,000 women between March and June 2021, aiming to understand the relationship between long COVID and menstrual health. Among participants, more than half of those suffering from long COVID reported experiencing heavier periods, in contrast to 40% of those who had experienced acute COVID-19 and 35% of those who had never tested positive for the virus.
The study defined long COVID as the persistence of symptoms for more than a month post-infection. It suggested that specific hormonal and inflammatory changes associated with long COVID, rather than the acute infection itself, might be responsible for these disruptions in menstrual cycles. Notably, women with long COVID exhibited elevated levels of the hormone 5α-dihydrotestosterone and higher concentrations of inflammatory cytokines.
Additionally, the research indicated that women with long COVID experienced exacerbated symptoms related to their menstrual cycles, with certain ailments like dizziness and fatigue worsening during menstruation. The study raises questions about the role of ovarian hormones in these symptoms.
While the findings provide valuable insights, researchers caution that the study's demographic limitations—primarily involving white women from the UK—necessitate further investigations to determine if the results are applicable across more diverse populations.
