What Causes Menstrual Blood to Have a Fishy Odor?
Disease description:
I’ve been experiencing frequent menstruation lately, and each time I have my period, the fishy, bloody odor is extremely strong—so much so that it makes me feel nauseous and uncomfortable. I’d like to ask a doctor: What causes menstrual blood to have a strong fishy odor?

Hello, a fishy or foul odor accompanying menstrual blood is often caused by a bacterial infection in the vagina. You may use a vaginal wash to clean the external genitalia; however, specific treatment should be initiated only after your period ends. In healthy women, menstruation occurs due to shedding of the endometrium triggered by declining levels of estrogen and progesterone—termed “hormone-withdrawal bleeding.” When hormone levels are low, both the reproductive system’s defensive capacity and the vagina’s self-cleansing ability are diminished; thus, bacterial infections are more likely during menstruation. We hope this information is helpful to you. Wishing you good health and happiness!
