Leukorrhea with a fishy smell does not usually heal on its own and requires targeted treatment to recover. Normal leukorrhea is colorless, odorless and transparent, but most of the causes of leukorrhea with fishy smell are related to vaginal inflammation. When vaginal inflammation is present, it leads to increased leucorrhea, odor and color change, along with vulvar burning and painful intercourse. Bacterial vaginosis can result in leucorrhea with a fishy smell, accompanied by vulvar itching and increased discharge. Trichomoniasis can also cause fishy smelling leukorrhea, which is yellowish-green and foamy, accompanied by itching of the vulva and vaginal opening. It is best to have a routine examination of the leukorrhea and choose different medication according to the pathogen. Normally, you should keep your vulva dry and clean, pay attention to personal hygiene and coital hygiene, and avoid getting cold to avoid gynecological inflammation.
