Is fungus in your gut? The candida culprit.

Candida might sound like just another buzzword in the wellness world—but for many, it’s the hidden culprit behind chronic fatigue, stubborn bloating, sugar cravings, brain fog, and more. If you’ve ever felt “off” in your digestion or energy and can’t quite put your finger on why, candida overgrowth may be worth exploring.

Let’s break down what candida overgrowth is, why it’s more common than ever, and how we help our patients in Naples, FL restore balance using a natural and functional medicine approach.

What Is Candida Overgrowth?

Candida is a type of yeast (a fungus) that naturally lives in the body—primarily in the mouth, gut, and vaginal area. In small amounts, it's harmless and even helpful. But under certain conditions, candida can multiply rapidly, throwing your gut ecosystem out of balance. This is called candida overgrowth, or more specifically, intestinal candidiasis when it occurs in the digestive tract.

Common Symptoms of Candida Overgrowth

Candida can affect different body systems, which means the symptoms can seem unrelated or vague at first. Here are some of the most common signs:

• Bloating, gas, or indigestion

• Fatigue or low energy despite adequate sleep

• Sugar and carb cravings

• Brain fog or poor concentration

• Recurring yeast infections

• Itchy skin, rashes, or fungal toenails

• White coating on the tongue (“thrush”)

• Constipation or diarrhea

• Mood swings, anxiety, or irritability

• Sensitivity to chemicals or strong smells

• Dark circles under the eyes.

  
  

If this list sounds familiar, you’re not alone—and you’re not crazy. Candida overgrowth is surprisingly common, especially in those with a history of high sugar diets, antibiotics, or chronic stress.

A 2017 study in Scientific Reports found that fungal overgrowth in the gut—especially Candida—may contribute to autoimmune flare-ups, particularly in people with a predisposition. Other studies have linked its role in IBS and IBD. It can have a variety of presentations and fuel various gut issues. 

What Causes Candida to Overgrow?

A healthy gut has a diverse balance of bacteria, yeast, and other microbes. Candida only becomes a problem when this balance is disrupted. Here are the most common triggers:

• Antibiotic use – wipes out good bacteria that keep candida in check

  
  

• High-sugar or high-carb diets – yeast thrives on sugar

  
  

• Chronic stress – weakens immunity and disrupts gut function

  
  

• Oral contraceptives and corticosteroids – can promote yeast overgrowth

  
  

• Weakened immune system – from illness or autoimmune conditions

  
  

• Alcohol overuse – damages the gut lining and feeds yeast

Even a few rounds of antibiotics years ago can set the stage for long-term candida imbalances—especially when paired with today’s ultra-processed, sugar-laden Western diet.

Our Functional Medicine Approach at Harmony Health Clinic (Naples, FL)

Wondering if candida is your issue? At Harmony Health Clinic, we can order advanced functional lab testing to assess for candida overgrowth, gut dysbiosis, leaky gut, and other hidden imbalances. While symptoms can offer clues, testing gives us a clearer picture—so we can create a treatment plan that’s personalized, precise, and effective. Don’t guess—get answers and a strategy that works.

We don’t jump straight into anti-fungal treatments. Why? Because successful candida protocols start by making sure your liver, digestion, and detox pathways are working properly first. This can prevent any negative die-off (herxheimer) symptoms from killing off the overgrown fungal species. 

Here’s how we approach it step-by-step:

Step 1: Open the Drainage Pathways

We begin by supporting your gut and liver so your body can safely eliminate toxins and yeast die-off. This phase often includes:

• Digestive enzymes to support food breakdown like Betaine HCL or Licorice root. 

  
  

• Liver support blends with milk thistle, dandelion, and NAC

  
  

• Gut-soothing herbs like slippery elm and marshmallow root

  
  

• Bowel support to ensure regular elimination

  
  

Step 2: Remove the Overgrowth

Once your system is ready, we move into the targeted removal phase. Depending on your individual case, we may use a combination of:

• Biocidin® – broad-spectrum botanical blend

  
  

• Olive leaf extract – antifungal and antioxidant

  
  

• Oregano oil (diluted) – powerful but potent

  
  

• Grapefruit seed extract – anti-yeast and antimicrobial

  
  

• Garlic (allicin) – nature’s antifungal hero

  
  

• Prescription antifungals – Nystatin, Itraconazole, or Fluconazole for stubborn cases

  
  

We carefully select your protocol based on symptom severity, lab results (if needed), and past history of antibiotic use.

Step 3: Rebuild and Restore (The 5 Pillars of Gut Health)

Treating candida is more than just “killing the yeast.” Our long-term success comes from rebuilding the gut environment. This includes:

1. Remove – the offending microbes and triggers

   
   

2. Replace – digestive enzymes and stomach acid

   
   

3. Reinoculate – with targeted probiotics

   
   

4. Repair – the gut lining with amino acids and herbs

   
   

5. Rebalance – lifestyle, stress, and diet

   
   

Nutrition: Your Secret Weapon Against Candida

You can’t starve candida into submission, but a low-sugar, anti-inflammatory diet makes a massive difference. We often recommend a low glycemic, whole-foods diet rich in:

• Non-starchy vegetables (leafy greens, cruciferous veggies)

  
  

• Protein (pasture-raised chicken, wild-caught fish, beef)

  
  

• Healthy fats (avocados, olive oil, coconut)

  
  

• Gut-friendly herbs and spices (turmeric, oregano, ginger)

  
  

We help you identify food sensitivities, lower your sugar intake, and rebalance blood sugar naturally—without feeling deprived.

Looking Deeper: The Original Root Cause

Candida rarely exists in a vacuum. At Harmony Health Clinic, we consider your whole story:

• Did candida symptoms begin after a round of antibiotics?

  
  

• Were you on hormonal birth control or steroids?

  
  

• Do you have mold exposure, mercury fillings, or chronic stress?

  
  

• Has your gut never felt “right” since childhood?

  
  

We take the time to uncover these patterns and tailor your care accordingly.

Candida overgrowth doesn’t have to be a lifelong struggle. With the right tools, guidance, and support, your body can return to balance.

At Harmony Health Clinic in Naples, FL, we combine modern testing with natural and functional medicine therapies to help you feel your best again.
