Alcohol and Yeast Infections: The Surprising Connection

You’ve probably heard the saying, “You are what you eat.” While drinking alcohol won’t literally turn you into a fungus, it can contribute to the development of yeast infections. This link isn’t often discussed, partly because yeast infections themselves are a sensitive topic. But understanding how alcohol affects your body can help you prevent these uncomfortable infections. Let’s explore the role alcohol plays in yeast overgrowth.

What Are Yeast Infections?

Yeast infections are fungal infections that can occur in various parts of the body, most commonly the mouth, throat, genitals, and other mucous membranes. Known medically as Candidiasis, these infections result from an overgrowth of Candida—a type of yeast naturally present in the body.

In healthy individuals, Candida helps with nutrient absorption and digestion, and its growth is kept in check by beneficial bacteria. A yeast infection happens when this balance is disrupted, allowing yeast to multiply uncontrollably or spread to other areas. Symptoms vary depending on the infection site but often include:

• White, bumpy patches
• Pain or soreness
• Fatigue
• Digestive issues like constipation or diarrhea
• Nausea
• Sinus infections
• Skin or nail fungus
• Mood swings
• Itchiness or redness

Does Alcohol Kill Fungus and Yeast?

High-concentration alcohol (60%–90%) is an effective disinfectant and can kill certain bacteria, viruses, and fungi. This has led to the misconception that drinking alcohol might have similar effects. However, alcoholic beverages contain much lower alcohol by volume (ABV)—typically 5%–40%—which is not strong enough to eliminate yeast or fungi. In fact, according to the USDA, while alcohol can harm beneficial gut bacteria, it does not kill yeast. The high concentration required would be toxic to humans.

In short, drinking alcohol won’t cure a yeast infection—it may actually make it worse.

The Link Between Alcohol and Yeast Infections

Alcoholic beverages are produced through yeast fermentation, which converts sugars into ethanol. But it’s not the yeast in alcohol that directly causes infections. Instead, alcohol’s toxins disrupt your gut microbiome, killing off healthy bacteria that normally keep Candida in balance. Heavy drinking can also lead to leaky gut syndrome, where harmful substances escape the digestive tract and affect other parts of the body.

Does Drinking Alcohol Cause Yeast Infections?

While other factors may set the stage for a yeast infection, alcohol can act as the trigger. Here’s how alcohol increases your risk:

• Weakens the immune system: Alcohol reduces antibody production and kills protective gut bacteria, making it easier for yeast to overgrow.
• Impairs liver function: The liver works overtime to process alcohol toxins, reducing its ability to filter Candida byproducts like acetaldehyde.
• Stresses adrenal glands: Alcohol prompts cortisol release, straining adrenal function and weakening defenses against fungal overgrowth.
• Spikes blood glucose: Yeast thrives on sugar, and alcohol can raise blood sugar levels, encouraging yeast proliferation.
• Feeds yeast directly: Alcohol contains sugars and carbs that yeast uses to multiply.

Consequences of Drinking With a Yeast Infection

Drinking during a yeast infection can worsen symptoms and delay healing. Complications may include:

• Heart arrhythmia
• Dizziness
• Brain fog
• Extreme fatigue
• Vomiting
• Severe pain

Long-term alcohol use can lead to chronic yeast infections and other health issues. A 2021 study on Alcohol Use Disorder found that patients had elevated Candida levels, but abstinence reduced fungal overgrowth and improved liver health.

How to Treat an Alcohol-Related Yeast Infection

Since these infections often start in the gut, focus on restoring balance with these steps:

• Stop drinking alcohol: Eliminate alcohol to stop fueling yeast growth. Hydrate with water and consider the benefits of quitting altogether.
• Limit sugar intake: Yeast feeds on sugar, so adopt a Candida-friendly diet rich in nonstarchy vegetables, lean proteins, and gluten-free grains.
• Take supplements: Boost your immune system with Vitamin C, probiotics, or caprylic acid to support healthy bacteria.
• Rebalance gut microbiome: Eat prebiotic and probiotic-rich foods to restore gut health.
• Use medication if needed: Antifungals or antibiotics may be prescribed. Avoid alcohol while on medication to prevent further disruption.

Preventing Alcohol-Related Yeast Infections

Prevention is always better than cure. Here’s how to reduce your risk:

• Practice moderation: Cut back or quit alcohol to protect your microbiome.
• Choose intentionally: Opt for low-sugar drinks or alcohol-free alternatives.
• Stay hydrated: Support your body’s natural detox processes by drinking plenty of water.
• Prioritize gut health: Eat a balanced diet to strengthen your immune system and prevent fungal overgrowth.

The Bottom Line

Yeast infections are unpleasant, and alcohol can significantly increase your risk. Over time, drinking weakens your immune system and disrupts your fungal balance, potentially leading to chronic issues. By cutting back on alcohol and adopting healthy habits, you can reduce your chances of infection and support overall well-being.
