Allergic Fungal Sinusitis

Understanding the root cause of stubborn sinus issues

Chronic Sinusitis & AFS

At Human Performance, we focus on finding the “why” behind symptoms. Chronic sinusitis can persist for months, often driven by an overlooked cause: Allergic Fungal Sinusitis (AFS).

What Is AFS?

AFS is a hypersensitive immune reaction to environmental fungi found in air and dust. It is not an infection—it’s an inflammatory cycle that keeps sinuses swollen and congested.

  • Long-lasting congestion
  • Nasal polyps
  • Thick mucus
  • Facial pressure
  • Reduced sense of smell
  • Recurrent sinus infections

Why This Happens

Your sinuses filter air constantly. In some individuals, the immune system overreacts to fungi, creating inflammation and blocked drainage.

  • Indoor air quality
  • Environmental exposures
  • Immune overreactivity
  • Inflammation patterns
  • Whole-body health

Clues AFS May Be Present

  • Dark or thick mucus
  • Symptoms lasting 12+ weeks
  • Recurrent polyps
  • Loss of smell
  • Symptoms returning quickly
