Possible causes include:not washing the penis properly using soaps and condoms that irritate the skinsexually transmitted infectionsdiabetes How probiotics affect pH levels Probiotics are health-promoting live bacteria and yeasts that are available in the form of dietary supplements. Probiotics can help restore the natural balance of bacteria throughout the body. This could help rebalance vaginal pH levels and combat vaginal infections. A 2019 meta-analysis notes that probiotics can prevent the bacteria associated with bacterial vaginosis (BV) from growing inside the vagina. However, further research is necessary to confirm this effect. Symptoms that vaginal pH levels may be out of balance According to the American College Of Obstetricians and Gynecologists, BV or yeast infections can occur due to a bacterial imbalance within the vagina. This imbalance has associations with an increase in vaginal pH levels that causes the vagina to become less acidic. Some symptoms that may indicate a vaginal infection include:skin rash or rednessitching or burning sensationunusual vaginal dischargeunpleasant odor When to speak with a doctor People should consult a doctor if they experience persistent or worsening vaginal symptoms despite taking a probiotic supplement or other over-the-counter treatment. A doctor can also check the vaginal pH level and determine if an individual has an infection. Frequently asked questions Some frequently asked questions about vaginal pH levels include: How do I fix my pH balance Some natural remedies that can help rebalance the vaginal pH include:Quitting smoking: A 2018 article notes that a person who smokes may have reduced levels of lactobacillus in their vagina. This can increase their chance of experiencing unpleasant odors or infections. Avoiding douching: Douching refers to cleaning the inside of the vagina with water and other fluids, such as vinegar and baking soda. This can increase the growth of harmful bacteria. If a person already has an infection, douching can spread the infection to the uterus, ovaries, and fallopian tubes. Using condoms: Semen is alkaline, so if it enters the vagina, it may cause an increase in vaginal pH levels. How do you know if your pH balance is off An imbalance in the vaginal pH can cause the following symptoms:unusual vaginal dischargeunpleasant odoritchinessskin redness or rashes Which vitamin is good for pH balance An older study from 2006 investigated the effects of topical vitamin C on vaginal pH levels in women with a high vaginal pH. They found that vitamin C can have a long lasting effect in lowering vaginal pH levels. What throws off a person s pH balance The following factors can disrupt vaginal pH levels:douching not changing tampons regularlyhaving sex without condomstaking antibiotics Summary The vagina has a natural pH level of under 4.5, a slightly acidic environment that helps protect against bacterial and yeast infections. A vaginal pH imbalance can occur due to douching, using vaginal wipes or deodorants, or having sex without a condom. Such imbalances can result in vaginal infections, which may cause several symptoms, including vaginal irritation, unusual vaginal discharge, and an unpleasant odor. People who experience symptoms of a vaginal infection may consider taking probiotics to help rebalance vaginal pH levels. These products are available for purchase online. Anyone who experiences persistent or worsening symptoms should speak with their doctor for a definitive diagnosis and appropriate treatment.
