Keto Crotch: Separating Fact from Fiction on This Keto Diet Side Effect

If you’ve spent any time in online forums dedicated to the ketogenic diet, you may have encountered the term "keto crotch." This unofficial side effect refers to a reported change in vaginal odor that some people experience when they switch to a high-fat, low-carb lifestyle.

While the conversations are real, the science behind the term is less clear. This article delves into the evidence, separating anecdotal claims from medical facts, to explore what "keto crotch" is, its likely causes, and most importantly, how to manage the symptoms safely and effectively.

What is "Keto Crotch"? The Unofficial Side Effect

"Keto crotch" is a colloquial term for a noticeable change in vaginal odor, which is sometimes accompanied by an increase in discharge, that some people report after starting the keto diet. The odor is often described as strong, unpleasant, and sometimes "fishy."

It’s important to note that this term emerged from personal accounts on platforms like Reddit and has been amplified by online media. It is not a recognized medical diagnosis.

Is "Keto Crotch" a Real Medical Condition?

While the symptoms people experience are real, there is no scientific evidence to support "keto crotch" as a distinct medical condition directly caused by ketosis. The medical community has not conducted studies on this specific phenomenon.

The consensus among health experts is that the symptoms attributed to "keto crotch" are more likely indicative of a common and treatable vaginal condition, which may be influenced by the drastic dietary change.

Potential Causes and Biological Mechanisms

While the "keto" name points to the diet, the actual biological cause is likely more complex than simply being in ketosis. The leading theories center on changes to the delicate vaginal microbiome.

The Leading Theory: Bacterial Vaginosis (BV)

The most plausible explanation for "keto crotch" symptoms is an underlying case of bacterial vaginosis (BV). BV is the most common vaginal condition in women aged 15-44 and occurs when there's an imbalance between the "good" and "bad" bacteria in the vagina.

The symptoms of BV are nearly identical to those described as "keto crotch":

• A strong, fishy odor, especially after sex.
• Thin, white or gray vaginal discharge.
• Vaginal itching or irritation.
• A burning sensation during urination.

How the Keto Diet Might Influence Vaginal pH

A healthy vagina is naturally acidic, with a pH between 3.8 and 4.5. This acidity, maintained by good bacteria called lactobacilli, creates a protective barrier against unhealthy bacteria.

Research suggests a potential link between diet and vaginal pH. An older study from 2007 and a 2020 review both noted a connection between high-fat diets and an increased risk of BV. The theory is that a diet very high in fat may increase the vagina's pH, making it less acidic (more alkaline). This shift can disrupt the natural balance, allowing the bacteria that cause BV to overgrow.

What About Ketones?

The ketogenic diet causes the body to produce ketones, and one of these, acetone, is responsible for the fruity smell known as "keto breath." Some have speculated that ketones could also be the source of "keto crotch." However, as Dr. Mary Jane Minkin, a board-certified OB/GYN, explained to PEOPLE magazine, while ketones smell unusual, there's no scientific evidence they are secreted through vaginal fluid to cause an odor. The more likely culprit remains a diet-induced pH imbalance.

How to Safely Manage and Treat Symptoms

If you're experiencing a change in vaginal odor, it's crucial to address it correctly and avoid remedies that could make things worse.

Step 1: See a Doctor

This is the most important step. A new or persistent vaginal odor warrants a visit to your gynecologist or healthcare provider. A doctor can perform tests to determine if you have BV, a yeast infection, an STI, or another condition. Self-diagnosing is risky, and only a professional can provide an accurate diagnosis and prescribe necessary treatment, such as antibiotics for BV.

Step 2: Safe At-Home Strategies and Prevention

While waiting for your appointment or to support your overall vaginal health, you can adopt these safe practices:

Dietary Adjustments

According to experts at Uqora, certain dietary tweaks may help support a balanced vaginal microbiome:

• Eat Alkaline-Rich Foods: Incorporate more dark leafy greens (spinach, kale) and cruciferous vegetables (broccoli, cauliflower) into your diet.
• Add Prebiotics and Probiotics: Foods like garlic, onions, and asparagus can help feed good bacteria. You might also consider a probiotic supplement formulated for vaginal health.

Hygiene Practices

• Clean Gently: Wash the outside of your genital area daily with warm water and a mild, unscented soap.
• Avoid Douching: Douching disrupts the natural pH and bacterial balance of the vagina and can increase the risk of infection, as noted by the CDC.
• Wear Breathable Underwear: Choose cotton underwear to help keep the area dry.
• Change Promptly: Don't linger in sweaty workout clothes or wet swimsuits.

Step 3: Avoid Harmful "Remedies"

Online forums may suggest remedies that are ineffective and potentially harmful. According to reports from Business Insider, using substances like apple cider vinegar, rubbing alcohol, or other disinfectants in or around the vagina can cause significant irritation and worsen pH imbalance. Always stick to professional medical advice.

Does Keto Crotch Affect Men?

The term "keto crotch" specifically refers to vaginal odor. However, men on a ketogenic diet can also experience changes in body odor. The groin area has many sweat glands, and the byproducts of ketosis, like acetone, can be excreted through sweat, potentially leading to a change in scent. The same principles of good hygiene and staying hydrated apply.

The Bottom Line

While "keto crotch" has become a buzzword, it is not a recognized medical condition. The symptoms are real but are most likely due to bacterial vaginosis (BV), a common infection that can be influenced by significant dietary changes.

The ketogenic diet's high-fat content may alter vaginal pH, increasing the risk for BV in some individuals. If you notice any concerning changes in your vaginal health, the best course of action is to seek professional medical advice for a proper diagnosis and treatment.
