The common causes of vaginal odor in women are as follows: first, the most common cause is due to reproductive system infections such as vaginitis, cervicitis and uterine adnexitis. This is because the inflammation will lead to an increase in vaginal secretions. Under the action of pathogenic bacteria, the vaginal secretions will become smelly and need to be treated promptly, mainly by improving the examination of the leucorrhoea and the treatment is mainly by local antibiotics. Secondly, vaginal odor is mainly caused by some women not paying attention to personal hygiene and changing underwear and sanitary napkins regularly. It is necessary to eat a reasonable diet that is light and appropriate.
