Positive leukorrhea hydrogen peroxide concentration suggests the presence of dysbiosis in the vagina. Under normal circumstances, vaginal pH is generally maintained at around 3.8-4.4, which is due to the secretion of lactic acid by Lactobacillus, which maintains an acidic environment in the vagina and can inhibit the growth and reproduction of pathogenic bacteria. If the acid-base balance of the vagina is broken due to various factors, such as prolonged application of antibiotics or a decline in the body’s immunity, Lactobacillus is inhibited and other dominant bacteria reproduce in large numbers, peroxidase positivity will occur. If the symptoms are not accompanied by obvious itching or vaginal pain, it is recommended that the vulva can be cleansed with Red Kernel Wash or Gynecological Cleansing Wash after dilution. If the discomfort in the vagina is obvious, you can clean the vulva and the vagina, and then put a suppository of diazoxide in the vagina for treatment, it is recommended to pay attention to the perineum hygiene, and change the underpants frequently.
