Normal leukorrhea is white, pasty and odorless. The pH of the test indicates its acidity. The pH of normal leukorrhea is between 4 and 4.5, which is weakly acidic and prevents pathogenic bacteria from multiplying in the vagina. A pH level of 5.4 usually indicates vaginitis or other diseases, and the patient needs to go to the hospital to diagnose and treat the problem with the results of the vaginal discharge test. However, patients do not need to worry too much, as it is usually not serious if it is not accompanied by abnormal bleeding.1. Vaginitis: common ones such as trichomoniasis and bacterial vaginitis. In the case of trichomoniasis, the discharge is increased, milky and foamy, thin in texture and accompanied by vulvar itching; in the case of bacterial vaginitis, the vaginal discharge is thin and uniform, off-white, with a pH of >4.5 and a fishy smell. Patients with vaginitis need to be treated with antibacterial drugs such as metronidazole and tinidazole under the guidance of professional doctors. 2. Other diseases: diseases such as interstitial cystitis and restricted vulvovaginitis can also cause patients to have a leucorrhea pH of 5.4. These two diseases can cause patients to have uncomfortable symptoms such as nocturia, frequent urination and lower abdominal pain. There is no effective conservative treatment for interstitial cystitis, which can be dilated and injected with dimethyl sulfoxide under local anesthesia. For limited vulvodynia, lubricants can be applied to relieve pain. In daily life, patients need to pay attention to the cleanliness and hygiene of the vulva, which can be washed daily with running water to prevent infection. In addition, try not to douche vaginally, as vaginal douching can disrupt the balance of the vagina’s own flora afterwards, making symptoms worse.
