If the leukorrhea is green and smells bad, consider trichomoniasis or bacterial vaginosis. This is because when there is trichomonas or bacterial infection in the vagina, it leads to increased vaginal discharge, which is often green or yellowish-green, foamy, and smells fishy. The discharge is often green or yellowish-green, foamy, and has a fishy odor. The odor is due to the anaerobic fermentation of carbohydrates in the vagina. If such a woman is able to do so, it is best to go to the hospital for a routine examination of the vaginal discharge to see what pathogens are causing it and to treat it according to the type of pathogens, and to prohibit sexual intercourse during treatment.
