A Case Where Gut Health Was the Missing Piece

At Sheen Vein & Cosmetics here in St. Louis, we often see patients who have been through years of conventional treatments without lasting relief. One recent case involved a 45-year-old woman who had been struggling with recurrent nasal fungal infections for years.

Despite seeing a skilled ENT, undergoing sinus surgery, receiving multiple courses of antibiotics, and using prescription nasal lavages, her symptoms always came back. Every few months, she would face the same congestion, sinus pressure, and nasal discharge that disrupted her daily life.

When she came to us, she was understandably frustrated. She wanted more than another temporary fix—she wanted to understand why this kept happening. That’s where a functional medicine approach changed everything.

Looking Beyond the Nose

Instead of focusing solely on her sinuses, we looked at her whole health picture. Chronic fungal infections often point to a weakened or imbalanced immune system. In many cases, the source isn’t just in the sinuses—it can be in the gut.

Through comprehensive testing, we found:

1. Gut Dysbiosis – An imbalance in the good and bad bacteria and yeast in her digestive tract.
2. Nutritional Deficiencies – Low levels of zinc, vitamin D, and other immune-supportive nutrients.

This combination was likely making her immune system less able to keep the nasal fungal infections under control.

The Gut-Immune Connection

Many people are surprised to learn that about 70% of your immune system is in your gut. A healthy gut microbiome communicates with immune cells, produces anti-inflammatory compounds, and helps your body recognize and fight pathogens.

When gut dysbiosis is present—whether from antibiotics, poor diet, or chronic stress—the immune system can become overworked, underpowered, and prone to letting infections slip through. This can make it harder to fight off a fungal overgrowth in the nasal passages.

How We Treated the Root Cause

We started with a personalized functional medicine plan designed to restore balance to her gut and strengthen her immune system:

• Targeted Antimicrobial Herbs – To reduce harmful bacteria and yeast in the gut without damaging the beneficial strains.
• High-Quality Probiotics – To rebuild her microbiome diversity.
• Nutritional Repletion – Including zinc, vitamin D, and omega-3 fatty acids for immune resilience.
• Anti-Inflammatory Diet – Focusing on whole foods, reduced sugar, and plenty of fiber.
• Lifestyle Support – Improving sleep and stress management to optimize immune health.

The Results

Within a few months, something remarkable happened—her nasal fungal infections stopped recurring. Her sinus passages stayed clear, her energy improved, and her immune system seemed stronger.

Now, over a year later, she has not needed another surgery, lavage, or antibiotic for fungal sinusitis. Her only seasonal issue is mild pollen allergies, which we manage with natural anti-inflammatory support.

Why Functional Medicine Works in Cases Like This

This case illustrates why simply treating the symptom—whether with antibiotics or surgery—may not be enough for chronic conditions. Without identifying and correcting the underlying triggers, symptoms will often return.

In her case, the trigger was a compromised immune system rooted in poor gut health and nutrient depletion. Once we restored both, her body was able to do what it was designed to do: maintain health naturally.

Could Gut Dysbiosis Be Affecting You?

If you have recurrent infections—whether in your sinuses, urinary tract, skin, or elsewhere—your immune system may be telling you something. Gut imbalances are far more common than most people realize, especially after multiple antibiotic courses.

At Sheen Vein & Cosmetics, we offer comprehensive functional medicine evaluations that include:

• Advanced stool testing for microbiome health
• Nutrient analysis for immune support
• Inflammation markers
• Food sensitivity testing
• Personalized treatment plans to restore balance

We also offer telemedicine consultations for patients across Missouri and Illinois who can’t make it into our St. Louis office.

The Takeaway

Chronic sinus or nasal fungal infections aren’t always just a local problem—they can be a whole-body signal that something deeper is going on. For our patient, healing her gut and correcting nutrient deficiencies was the key to finally breaking the cycle of infection.

If you’ve been told “you’ll just have to live with it,” there may be another way. Functional medicine looks at the bigger picture and aims to restore health from the inside out.
