A recent study has revealed that women experiencing prolonged periods lasting over eight days may be facing effects linked to long COVID. Published in Nature Communications on September 16, 2025, the research sheds light on how lingering COVID-19 symptoms can impact menstrual health, even months or years after the initial infection.
The study found that women with long COVID are more likely to experience heavier bleeding longer periods and spotting between cycles. Compared to women who did not contract COVID, those affected are twice as likely to have menstrual cycles extending beyond eight days. These irregularities may signal that long COVID is influencing hormonal balance and uterine response.
Researchers explain that lingering COVID-19 effects can alter bodily functions and trigger inflammation. In women with long COVID, the uterus shows reduced sensitivity to hormones due to low progesterone receptor activity, possibly linked to higher androgen levels and endometrial inflammation. Despite these changes, ovarian function and fertility appear largely unaffected.
This finding broadens the understanding of long COVID, which is usually associated with fatigue shortness of breath and sleep disturbances. Women experiencing extended periods or unusual bleeding patterns after COVID should consult a healthcare professional to rule out underlying conditions and receive guidance on managing their menstrual cycle.
While hormonal disruption is a key factor, maintaining overall nutrition and magnesium levels may also help reduce cramps and support cycle regulation. Early awareness and medical advice can help women navigate these unexpected changes effectively.
