Keto Diet: Vaginal Odor Side Effect?

The ketogenic diet is a high-fat, low-carb eating plan that has become increasingly popular for weight loss. However, it has also been associated with a range of side effects, including keto breath, keto flu, and keto diarrhea. One lesser-known potential side effect is keto crotch, a term used to describe an increase in vaginal odor and discharge that some women experience while on the keto diet. While there is limited scientific research on this topic, many women have reported their experiences with keto crotch, primarily through online platforms such as Reddit.

Keto crotch is believed to be caused by changes in vaginal pH due to the high-fat, acidic nature of the keto diet. A healthy vaginal pH is typically acidic, ranging from 3.5 to 4.5 on the pH scale, which helps prevent the growth of certain microorganisms. However, when the body is in a state of ketosis and breaking down fats for energy, the resulting ketones can alter the vaginal pH, making it more alkaline. This change in pH can lead to an overgrowth of bacteria, resulting in an infection known as bacterial vaginosis (BV), which is characterized by a strong vaginal odor and discharge.

While the link between the keto diet and keto crotch has not been conclusively proven, there are steps that can be taken to mitigate this potential side effect. These include consuming more alkaline foods, such as leafy greens and non-starchy vegetables, to balance the body's pH, as well as supporting the growth of 'good' bacteria in the gut through probiotic-rich foods and supplements. It is also important to avoid douching, as the vagina is self-cleansing, and to seek medical advice if the issue persists or is accompanied by other symptoms.

Keto Crotch: Fact or Fiction?

The internet has been abuzz with talk of "keto crotch", a supposed side effect of the popular keto diet. But is there any truth to these claims? Let's take a closer look.

Keto crotch refers to a noticeable change in vaginal odor after starting a keto diet. The keto diet, for those unfamiliar, is a high-fat, low-carbohydrate diet that is often touted for its weight loss benefits. The diet involves significantly reducing carbohydrates and increasing fats, which shifts the body into a state of ketosis, where it burns fat for energy instead of carbohydrates.

Some women who have embarked on the keto diet have reported experiencing an intense vaginal odor, which has been described as "musky", "fishy", or similar to "urine and discharge". This phenomenon has been dubbed "keto crotch".

While there is a lot of anecdotal evidence from women who have experienced keto crotch, there is currently no scientific research confirming that it is a legitimate side effect of the keto diet. However, doctors agree that the increase in acidic foods and beverages associated with the keto diet could disrupt the vaginal pH, leading to vaginal odor.

A healthy vaginal pH is acidic, typically between 3.5 to 4.5 on the pH scale. This acidity helps to prevent the growth of certain microorganisms and maintain a healthy balance of bacteria. However, when the diet becomes highly acidic, it can make the vagina more alkaline, allowing infection-causing bacteria to multiply. This can lead to issues such as bacterial vaginosis, yeast infections, and UTIs.

What to Do if You Experience Keto Crotch

If you are experiencing keto crotch, there are a few things you can try. Firstly, it is important to avoid douching, as this can disrupt the vaginal pH and make the problem worse. Secondly, try incorporating more alkaline foods into your diet, such as leafy greens, non-starchy vegetables, and plant-based fats. This can help bring the vaginal pH back down to its ideal acidic level.

In addition, supporting the growth of "good" bacteria in the gut and vagina may help reduce the likelihood of keto crotch. This can be done by including probiotic-rich foods in your diet, such as yogurt, kimchi, and sauerkraut, as well as prebiotic foods like garlic, leeks, and onions.

If the odor persists or is accompanied by other symptoms such as itching, burning, or abnormal discharge, it is important to consult a doctor or gynecologist to rule out any underlying infections or gynecological issues.

The Science Behind Vaginal Odor

The vagina has a natural bacterial flora that keeps a good balance and ensures a healthy vaginal microbiome. This natural bacteria means that cervical mucus in the vagina always has a smell. A healthy vagina can have a variety of odors, and these changes are likely a result of your menstrual cycle, your hygiene habits, or just you being you.

The vaginal pH in a person of reproductive age is slightly acidic, which means it’s natural for it to have a tangy odor. The precise makeup of this bacteria changes on a daily, sometimes hourly, basis. The groin contains a collection of sweat glands, so it's not surprising that the vagina isn't odorless.

The natural acidic pH of a healthy vagina is somewhere between 3.8 and 4.5 on the pH scale. This acidity is an essential factor in maintaining vaginal health and allows good bacteria to thrive while preventing unhealthy bacteria from spreading. An alkaline vagina is more susceptible to infection-causing bacteria.

There are many potential causes of a change in vaginal odor, and it's important to recognise if the smell is abnormal for you. A strong, fishy odor can be a sign of bacterial vaginosis, a common vaginal infection. Trichomoniasis, a sexually transmitted infection, is also known for its pungent fishy odor.

A coppery, metallic vaginal odor is usually caused by blood, often from menstruation. A sweetish tinge is no cause for concern, as the vaginal pH is an ever-changing bacterial ecosystem. A chemical-like smell, similar to bleach or ammonia, could be a sign of a urinary tract infection.

A strong vaginal odor can also be caused by a forgotten tampon, yeast infection, hormonal changes, or, in rare cases, gynecological cancers.

A change in diet can also impact vaginal odor. A high-fat, low-carb diet, like the keto diet, can impact your vaginal pH balance, resulting in vaginal odors. This is known as "keto crotch". A diet high in fat, particularly saturated fat, can alter pH levels, changing vaginal acidity. A high pH level can create the perfect environment for bacteria or yeast to grow in the vaginal area.

If you experience an unusual or strong vaginal odor, it's important to see a doctor to rule out any underlying conditions.

Keto Diet and Vaginal pH

The keto diet is a high-fat, low-carbohydrate eating plan that has become increasingly popular. While it has been associated with several health benefits, such as weight loss and improved cognition, it can also lead to various side effects, including an unpleasant vaginal odor, commonly known as "keto crotch."

The Impact of Keto Diet on Vaginal pH

The keto diet's high-fat content can affect vaginal pH levels. A healthy vaginal pH level is typically between 3.8 and 4.5, which is moderately acidic. This acidity is crucial for maintaining vaginal health by creating an environment where good bacteria thrive and inhibiting the growth of unhealthy bacteria.

However, when following a keto diet, the increased consumption of acidic foods and beverages like dairy, meat, poultry, and coffee can disrupt this delicate balance. The high-fat intake, especially saturated fats, can lead to an increase in vaginal pH levels, making the vagina more alkaline. This altered pH balance can have several consequences:

• Bacterial Overgrowth: The higher pH level creates an environment conducive to the growth of certain microorganisms, including bacteria and yeast. This imbalance in the vaginal ecosystem can lead to infections and unpleasant odors.
• Increased Risk of Bacterial Vaginosis (BV): BV is a common vaginal infection characterized by an unpleasant odor, discharge, and other symptoms. The keto diet's impact on vaginal pH may increase the risk of developing BV.
• Other Infections: In addition to BV, the altered vaginal pH can make individuals more susceptible to yeast infections and urinary tract infections (UTIs).

Addressing Keto Crotch

While keto crotch is an unpleasant side effect of the keto diet, there are several strategies to mitigate it:

• Dietary Adjustments: Consuming a balanced diet with healthy carbohydrates can help restore vaginal pH levels. Including alkaline foods, such as most vegetables and nuts, dark leafy greens, and cruciferous veggies like broccoli and cauliflower, can counteract the acidity.
• Probiotics: Taking a daily probiotic supplement, especially one formulated for vaginal health, can help balance the vaginal microbiome and reduce the risk of infections and odor.
• Avoiding Douching: Vaginal douching can disrupt the natural vaginal pH and increase the risk of bacterial vaginosis and yeast infections. It is generally recommended to avoid douching.
• Monitoring Carbohydrate Intake: Restricting carbohydrates too much can exacerbate keto-related body odors. Keeping net carb intake between 20 to 50 grams per day can help maintain a steady level of ketosis and minimize side effects.
• Chlorophyll-Rich Foods: Eating chlorophyll-rich foods like spinach, mustard greens, and parsley can help reduce keto-related odors, including keto crotch.

In conclusion, the keto diet's impact on vaginal pH can lead to keto crotch and other vaginal health issues. However, by understanding the underlying causes and implementing appropriate strategies, individuals can effectively manage these side effects and maintain a healthy vaginal pH while following the keto diet.

Preventing and Treating Keto Crotch

Keto crotch is a noticeable change in vaginal odor after starting the keto diet. While there isn’t a lot of scientific research on this topic, many women report experiencing keto crotch. Symptoms typically appear after about a month of starting keto and include a strong vaginal smell and sometimes unusual discharge. The odor is often compared to a sour or fishy smell, and the severity of keto crotch can range from mild to very unpleasant.

How to Prevent Keto Crotch

Eat More Alkaline Foods

It may be counterintuitive, but consuming more alkaline foods may help bring your vagina back to its ideal acidic pH. A healthy vaginal pH is between 3.5 and 4.5, on the acidic end of the spectrum, which helps prevent the growth of certain microorganisms. When you stay in ketosis for a long time, the ketones you're generating and the foods you're eating (especially if they're acidic) could be altering the pH of your vagina, possibly causing it to become more alkaline and allowing an overgrowth of bacteria.

Alkaline foods include leafy greens and most other non-starchy vegetables such as broccoli, cabbage, and Brussels sprouts; plant-based fats such as avocados, coconut oil, and olive oil; herbs like maca; and some fruits.

Support Your Gut's "Good" Bacteria

Research suggests that poorly formulated high-fat diets may alter the composition of the gut microbiome for the worse. Because the gut microbiome may function as a sort of "reservoir" for vaginal microorganisms, keeping the gut healthy and balanced will likely help keep your vagina healthy and balanced, too—and may reduce your likelihood of experiencing "keto crotch."

Include probiotic-based foods in your diet, such as yogurt, kimchee, and sauerkraut, as well as prebiotics (which feed the "good" probiotic bacteria in your gut) in the form of garlic, leeks, onions, and a variety of fiber-rich foods. These foods support a healthy vaginal pH, gut health, and immune function.

For further support, consider supplementing with a probiotic formulated with four of the most highly researched species: Bifidobacterium lactis, Bifidobacterium longum, Lactobacillus acidophilus, and Lactobacillus plantarum. The supplement should contain 30 billion CFUs (colony-forming units) of these strains, taken in one dose prior to bedtime.

How to Treat Keto Crotch

Don't Douche

The vagina is self-cleansing and douching can flush out good bacteria, allowing more bad bacteria to grow.

Use Topical Coconut Oil

Use natural topical products to help counter vaginal odor. Coconut oil is very moisturizing and makes an excellent lubricant. It also contains a compound called lauric acid that has antiviral, antibacterial, and antifungal properties. Just a small dab rubbed over the vulvar area is all you need.

Test Your Urinary pH

Test your urine using pH strips that you can purchase at your pharmacy or online. The results are rapidly expressed as a color change. The greener the strip, the more alkaline your body. You want to have a pH of at least 7; anything less is acidic and signifies you may need to add more alkaline foods to your diet and scale back on acid-forming foods like meat, cheese, and animal fats.

Consult Your Physician or Gynecologist

If you're experiencing "keto crotch" or any sort of abnormal vaginal odor, see your doctor to find out what's really going on. Don't be shy—vaginal odor is one of the biggest complaints gynecologists hear from women, and usually, it's nothing to worry about. In some cases, this odor might indicate a vaginal infection such as bacterial vaginosis (BV) (fishy smell with a white or gray discharge), a yeast overgrowth (no smell, or a bready or beer-like smell with white discharge), or an STD called trichomoniasis (putrid odor with a greenish discharge).

Keto Crotch and Gut Health

The ketogenic diet is a popular, low-carb, high-fat diet that has been associated with rapid weight loss. However, it also comes with a host of side effects, including keto flu, keto breath, and keto diarrhea. One lesser-known side effect is "keto crotch," where women experience an increase in vaginal odor after starting the diet. While there is limited scientific research on this topic, many women have reported experiencing this issue.

Keto crotch refers to a noticeable change in vaginal odor after starting the keto diet. Symptoms typically appear after about a month and include a strong vaginal smell, sometimes accompanied by unusual discharge. The odor is often described as sour or fishy, and the severity can range from mild to very unpleasant.

The exact cause of keto crotch is not fully understood, but it is believed to be related to the metabolic changes that occur when the body enters ketosis. As the body breaks down fat for energy, it produces ketones, including acetone, which is also found in nail polish remover. The buildup of acetone in the body can lead to changes in body odor, including keto breath and likely impacts vaginal odor.

Additionally, the high-fat content of the keto diet can impact vaginal pH levels, creating an environment conducive to the growth of certain microorganisms, such as bacteria and yeast. This imbalance in vaginal pH can lead to bacterial vaginosis (BV), a common vaginal infection that can cause an unpleasant odor.

How to Address Keto Crotch:

If you are experiencing keto crotch, there are several steps you can take to reduce the symptoms:

• Avoid restricting carbohydrates too much: While a low-carb diet is crucial for ketosis, eating too few carbs can increase keto-related body odors. Aim for 20-50 grams of net carbs daily.
• Eat plenty of green leafy vegetables: Leafy greens are rich in chlorophyll, which helps neutralize body odors.
• Avoid vaginal douche products: Douching can disrupt the vaginal pH balance and increase the risk of bacterial vaginosis and yeast infections.
• Consume more alkaline foods: Increasing your intake of alkaline foods can help balance the vaginal pH and reduce the growth of odor-causing microorganisms.
• Support your gut health: The gut microbiome may influence vaginal health. Include probiotic-rich foods such as yogurt, kimchee, and sauerkraut, as well as prebiotic foods like garlic, leeks, and onions.
• Consult your doctor: If the odor persists or is accompanied by other symptoms, consult your gynecologist to rule out any underlying gynecological issues.

Gut Health on the Keto Diet:

While the keto diet can have benefits, it is important to consider its impact on gut health. A high-fat diet may alter the composition of the gut microbiome, potentially leading to an imbalance of good and bad bacteria. This can have indirect effects on vaginal health, as the gut may function as a reservoir for vaginal microorganisms. Therefore, supporting gut health through probiotic and prebiotic foods or supplements may also help reduce the likelihood of experiencing keto crotch.
