COVID-19 vaccine can increase the menstrual cycle length: Study Latest Videos
News 24
As per the findings of the new study, COVID-19 vaccine has increased the menstrual cycle length of nearly one day of the women who have received one dose of the vaccine.
The increase in cycle length--a longer time between bleeding--was not associated with any change in the number of days of menses (days of bleeding). The study has been published in the 'Obstetrics & Gynecology Journal'.
The authors, led by Alison Edelman, M.D., M.P.H., of Oregon Health & Science University, Portland, noted that menstrual cycles typically vary a small amount from month to month, and the increase they saw was well within the range of normal variability.
They added that additional research is needed to determine how COVID-19 vaccination could potentially influence other menstrual characteristics, such as associated symptoms (pain, mood changes, etc.) and characteristics of bleeding (including heaviness of flow).
