Preventing Vaginal Yeast Infections by Controlling pH Levels

Understanding Vaginal pH Levels and Yeast Infections

Vaginal yeast infections can be extremely uncomfortable and irritating. They are caused by an overgrowth of a fungus called candida which naturally lives in the vagina. When candida grows out of control, it causes infection, inflammation, and itching.

One of the most important factors that impacts candida overgrowth is the pH balance in the vagina. pH refers to acidity or alkalinity levels. Maintaining the right pH can help prevent infections from occurring.

What is a Normal Vaginal pH Level?

The vagina is a delicate ecosystem with a natural balance of bacteria and yeast. In most healthy women, the normal vaginal pH is between 3.5 and 4.5. This slightly acidic state protects the vagina and prevents overgrowth of yeast or bacteria.

Lactic acid produced by healthy vaginal bacteria helps keep pH levels low. When pH rises above 4.5, it creates an environment where yeast is more likely to grow into an infection. Understanding what raises vaginal pH can help you prevent yeast overgrowth.

How pH Levels Affect Candida

Candida albicans, the fungus responsible for vaginal yeast infections, grows best in a pH range of 5 to 8. At pH levels above 4.5, the increase in alkalinity encourages candida growth. At lower pH levels, candida growth is restricted and the beneficial bacteria in the vagina can keep it under control.

When pH rises, it neutralizes the acidic environment that usually prevents candida overgrowth. The higher pH causes the healthy populations of Lactobacillus bacteria to decline. With less competition, candida is free to multiply rapidly and cause inflammation and infection.

Factors That Affect Vaginal pH Levels

There are several factors that can disrupt the delicate acidic pH in the vagina and encourage candida growth. Being aware of these can help you take preventative steps:

• Douching - This disrupts healthy bacteria and washes away protective acidity
• Scented soaps, bath products, creams - These can alter pH levels
• Semen - Has an alkaline pH around 7.5 to 8
• Blood - Also alkaline with pH of 7.4
• Hormonal changes - Estrogen fluctuations affect pH
• Antibiotics - Kill good bacteria allowing yeast overgrowth
• Pregnancy - Hormonal and pH changes increase risk
• Medical conditions - Diabetes or immune issues can increase susceptibility
• Clothing - Tight pants, pantyhose can trap moisture and heat
• Personal lubricants - Many popular brands disrupt natural pH

Preventing Vaginal Yeast Infections

While yeast infections are very common, you can take steps to avoid getting them. Preventing pH changes that allow candida overgrowth is key. Here are some tips:

Avoid Douching

Douching removes healthy vaginal bacteria that produce protective acids. This allows pH to rise and makes yeast infections more likely. The American College of Obstetricians and Gynecologists advises against douching.

Use Gentle, Unscented Products

Scented tampons, soaps, washes, wipes and creams can affect vaginal pH and flora. Choose gentle, fragrance-free products designed specifically for vaginal health.

Change Out of Sweaty Exercise Clothes

Wet clothing traps heat and moisture. Yeast thrives in warm, moist environments. After working out, shower and put on clean, breathable underwear and clothes.

Wear Cotton Underwear

Cotton is more breathable than fabrics like nylon or spandex. Well-ventilated cotton underwear can help prevent the warm, moist conditions that encourage yeast growth.

Avoid Irritating Feminine Products

Deodorant tampons, scented pads and some feminine wipes contain chemicals that can irritate skin. This makes infections more likely by damaging protective mucous membranes.

Take Probiotics

Probiotic supplements contain healthy bacteria that help maintain normal vaginal pH. They support the good bacteria that restrict candida overgrowth by producing protective acids.

Practice Good Hygiene

Carefully wipe from front to back after using the bathroom. This prevents spreading bacteria from the anus where candida also lives. It’s also important to change tampons and menstrual pads frequently.

Don’t Hold in Urine

Holding urine allows bacterial overgrowth. Fully emptying the bladder regularly flushes bacteria out and prevents infections in the urinary tract and vagina.

Avoid Unprotected Sex

Both semen and saliva are alkaline fluids that raise pH. Using condoms helps avoid exposing the vagina to these Ph-disrupting fluids.

Eat Yogurt and Fermented Foods

Yogurt contains probiotics that promote vaginal health. Kefir, kimchi, sauerkraut and other fermented foods also contain beneficial bacteria that help maintain ideal pH.

Stay Blood Sugar Balanced

High blood sugar from diabetes allows yeast overgrowth. Keeping blood sugar stable with diet, exercise and medication if prescribed prevents infections.

Consider Boric Acid Suppositories

Boric acid vaginal suppositories lower vaginal pH and have antifungal properties. They can help prevent recurrent infections if used periodically. Check with your doctor before starting this treatment.

Treating Vaginal Yeast Infections

If you think you have a yeast infection, proper treatment is important. Left untreated, infections can drag on and make you more susceptible to other illnesses. Here’s what you need to know about relieving symptoms:

See Your Doctor

Make an appointment with your gynecologists or primary care provider to confirm you actually have a yeast infection. Rarely, symptoms can indicate a more serious condition like a STD or bacterial infection.

Consider Prescription Medication

For moderate to severe infections, doctors often prescribe a strong one-dose antifungal medication called Diflucan or Fluconazole. This oral pill clears up stubborn or recurrent infections.

Use Over-the-Counter Creams

For mild to moderate infections, OTC topical antifungal creams containing ingredients like miconazole or clotrimazole can be effective. These help clear infection while soothing inflammation and discomfort.

Try Probiotic Suppositories

Probiotic suppositories contain strains of protective bacteria that lower pH levels in the vagina. They help restore healthy bacteria levels to prevent future recurrences.

Eat More Yogurt

Consuming yogurt with live active cultures may reduce yeast infection duration. Look for labels listing Lactobacillus strains like L. acidophilus. These good bacteria fight infection.

Take Garlic Supplements

Some clinical research shows garlic has antifungal properties that may help treat yeast infections. Garlic tablets, oils or fresh cloves added to food can aid recovery.

With proper treatment and by avoiding triggers that increase pH and encourage candida overgrowth, you can break the cycle of chronic yeast infections.
