vaginal ph explained

At Home Health, we understand the importance of maintaining a healthy vaginal environment, and we’re here to empower you with knowledge and practical tips. In this article, we’ll explore the ins and outs of vaginal pH, why it matters, and how to keep it in harmony naturally. Whether you’re looking to understand the fundamentals of vaginal pH or seeking solutions for maintaining or restoring balance, you’ve come to the right place.

What is Vaginal pH?

Vaginal pH is a crucial and often overlooked aspect of female reproductive health. It refers to the measurement of acidity or alkalinity in the vagina, expressed on a scale from 0 to 14, with 7 being neutral. Understanding vaginal pH is essential because it plays a significant role in maintaining a healthy and balanced vaginal environment.

What is a Normal Vaginal pH Range?

The vaginal pH is not constant and can vary throughout a woman’s life. However, under typical circumstances, the vaginal pH tends to be slightly acidic, falling within the range of 3.8 to 4.5. This natural acidity is primarily due to the presence of beneficial bacteria called lactobacilli, which produce lactic acid. The acidic environment is essential for several reasons:

  • Infection Prevention: The acidic pH helps prevent the overgrowth of harmful bacteria and yeast, reducing the risk of infections such as bacterial vaginosis and candidiasis (yeast infections).
  • Protection Against STIs: A low pH can act as a barrier against sexually transmitted infections (STIs) by creating an inhospitable environment for pathogens.
  • Sperm Survival: The acidic environment is not conducive to sperm survival, except during ovulation when the pH temporarily rises to accommodate fertilisation.

Factors Affecting Vaginal pH:

Several factors can influence and potentially disrupt the delicate balance of vaginal pH. These include:

  • Menstrual Cycle: Vaginal pH can fluctuate throughout the menstrual cycle, with the lowest pH occurring during menstruation and the highest during ovulation.
  • Hygiene Products: The use of harsh or scented soaps, douches, and feminine hygiene products can disrupt vaginal pH by altering the natural bacterial balance.
  • Sexual Activity: Semen has an alkaline pH, which can temporarily increase vaginal pH after intercourse. This typically returns to normal within a few hours.
  • Diet: Diet can impact vaginal pH, as certain foods may promote the growth of beneficial or harmful bacteria in the vagina.
  • Hormonal Changes: Changes in hormone levels, such as those during pregnancy or menopause, can affect vaginal pH.

Signs of an Imbalanced Vaginal pH:

An imbalanced vaginal pH can lead to discomfort and health issues, and there are several signs you should be looking out for. It’s important to note that while these signs and symptoms can strongly suggest an imbalanced vaginal pH, they may also be indicative of other vaginal health issues. If you experience any of these symptoms persistently or if they are accompanied by severe pain, it is advisable to consult a healthcare provider for a proper diagnosis and appropriate treatment.

Unusual Vaginal Odour: 

One of the most noticeable signs of an imbalanced vaginal pH is a change in vaginal odour. A healthy vagina typically has a mild, slightly tangy odour, which is usually not unpleasant. However, an imbalanced pH can lead to a foul or fishy odour that may become more prominent, especially after sexual intercourse. This change in odour is often associated with bacterial vaginosis (BV), a common vaginal infection caused by an overgrowth of harmful bacteria.

Abnormal Vaginal Discharge: 

The consistency, colour, and odour of vaginal discharge can be affected by changes in pH. An imbalanced pH may lead to abnormal discharge, which can vary in appearance from thin and watery to thick and clumpy. Discharge may appear greyish or yellowish and may have an unpleasant odour.

Itching and Irritation: 

An imbalanced vaginal pH can result in itching, burning, or general discomfort in the genital area. These symptoms are often attributed to the irritation of sensitive vaginal tissues due to an overgrowth of harmful microorganisms or a disruption of the natural vaginal flora.

Increased Susceptibility to Infections: 

When the vaginal pH is not within its healthy range, the vagina becomes more susceptible to infections. Changes in pH can create an environment where harmful bacteria, such as Gardnerella vaginalis (associated with BV) or Candida (causing yeast infections), can thrive. This heightened susceptibility to infections can lead to recurrent episodes of bacterial vaginosis or yeast infections.

Discomfort During Sexual Intercourse: 

An imbalanced pH can cause discomfort or pain during sexual intercourse. This discomfort may be due to irritation and inflammation of the vaginal tissues and the potential for increased friction and sensitivity.

Urinary Symptoms: 

In some cases, an imbalanced vaginal pH may cause urinary symptoms such as burning or a frequent urge to urinate. This can happen when imbalances in the vaginal flora affect the urethra, which is located close to the vagina.

Vaginal pH Balance (BV) Tests

If you’re still unsure on your vaginal pH balance, you can undertake an at-home vaginal pH balance (BV) test. 

Vaginal pH Balance (BV) Tests are readily available from Home Health and provide a convenient way to assess your vaginal pH balance in the comfort of your own home. These tests are designed to be incredibly user-friendly, making the process easy and straightforward for readers. To use the test, you typically, insert a clean, dry pH test strip into your vagina for a few seconds and then compare the resulting colour change to a provided colour chart. This colour chart corresponds to different pH levels, allowing you to determine your vaginal pH balance quickly and accurately. 

It’s a hassle-free method for monitoring your vaginal health and can be a valuable tool in identifying potential imbalances or issues that may require further attention or medical guidance.

How to Maintain a Healthy Vaginal pH

Maintaining a balanced vaginal pH is crucial for overall vaginal health and comfort. However, sometimes factors like hormonal changes, poor hygiene practices, or infections can disrupt this delicate balance, leading to an imbalanced vaginal pH. If you suspect that you have an imbalanced pH or are experiencing symptoms like unusual odour, abnormal discharge, itching, or irritation, it’s essential to take steps to address the issue promptly.

How to Balance Vaginal pH Naturally

If you suspect an imbalanced pH and it’s causing discomfort, you can try several home remedies to help restore balance. Remember that these remedies should not replace professional medical advice, especially if symptoms persist or worsen.

Baking Soda Bath: 

Adding a cup of baking soda to a warm bath can help alleviate itching and discomfort. Baking soda has alkaline properties that may help neutralise excess acidity in the vaginal area. However, avoid using this remedy too frequently, as it can disrupt the natural balance of vaginal flora.

Apple Cider Vinegar (ACV): 

Diluted apple cider vinegar can be used as a natural douche to help restore vaginal pH. Mix one to two tablespoons of ACV with warm water and use it as a rinse. Be cautious and consult your healthcare provider before trying this remedy, as it may not be suitable for everyone.


Yoghurt contains probiotics, which are beneficial bacteria that can help rebalance the vaginal flora. You can apply plain, unsweetened yoghurt to the vaginal area or consume it orally to promote the growth of beneficial bacteria.

How to Treat Vaginal pH Professionally 

If home remedies don’t provide relief or if symptoms worsen, it’s essential to consult a healthcare provider. They can diagnose the specific cause of the imbalance and recommend appropriate medical treatments, which may include:

Over-the-Counter (OTC) Options: 

Some OTC products, such as vaginal pH-balancing gels or suppositories, can help restore the vaginal pH to its normal range. These products are available at most pharmacies and can be used under the guidance of a healthcare professional.

Prescription Medications: 

In cases of severe or recurrent imbalances, a healthcare provider may prescribe medications, such as antibiotics or antifungal creams, to treat underlying infections and restore vaginal pH.
