The vagina's natural defense mechanism is its acidity. This is because the vagina has a unique environment that is hostile to many microorganisms. One way it keeps these invaders at bay is through its low pH level, which makes it difficult for bacteria to survive. The acidity in the vagina can be measured using a pH scale, which ranges from 0 to 14. A pH of 7 is neutral, while anything below 7 is considered acidic and anything above 7 is basic or alkaline. In general, the vagina maintains a slightly acidic pH between 3.8 and 5.5. When the pH drops below this range, it becomes more conducive to the growth of harmful bacteria and yeast. For example, a drop in pH below 4.5 can allow bacteria such as Gardnerella vaginalis to thrive, leading to bacterial vaginosis (BV), an imbalance of bacteria in the vagina. Other factors that affect vaginal pH include hormonal changes during menstruation, pregnancy, and menopause, as well as diet and medications such as antibiotics. Additionally, sexual intercourse can alter the pH of the vagina temporarily, but does not typically cause permanent changes unless there is a significant imbalance of bacteria present beforehand. To preserve vaginal health, women should practice good hygiene habits such as wiping front-to-back after urination and refraining from douching, which can disrupt the natural balance of bacteria in the vagina. If you experience symptoms such as itching, burning, odor, or abnormal discharge, consult your doctor for proper treatment. The vagina's natural defense mechanism is its acidity.
