Positive sialoglucosidase, which is usually found in the leucorrhea examination, is an enzyme secreted by anaerobic bacteria such as Gardnerella. Generally this suggests bacterial vaginosis and can be referred to other items in the routine leucorrhea to see if there are other bacterial and pathogenic infections. If there are other infections, they need to be treated at the same time. If it is only positive, don’t worry, it is a bacterial vaginosis, it is not serious and it is easy to cure. During the treatment period, don’t eat spicy and stimulating food, drink yogurt with good bacteria, don’t douche the vagina, use vaginal plugs under the guidance of a gynecologist in a regular hospital, and review the leucorrhoea routine after a week of treatment and stopping the medication to see if it is cured.
