Post-Viral & Long COVID Recovery in Carmel, Indiana

At The Functional MDs, our double board-certified physicians provide structured, systems-based care for patients experiencing persistent symptoms after viral illness, including Long COVID. Our approach focuses on restoring energy, cognitive clarity, and immune resilience through personalized medical evaluation and targeted support.

What Is Post-Viral & Long COVID Recovery?

Post-viral syndrome refers to a state of ongoing symptoms that persist after the acute phase of a viral infection has resolved. Long COVID is a form of post-viral illness in which immune, neurologic, metabolic, and autonomic systems remain dysregulated weeks or months after COVID-19 infection.

At The Functional MDs, our physicians use advanced testing and root-cause evaluation to identify ongoing inflammation, immune dysfunction, nervous system imbalance, and metabolic stress contributing to long COVID symptoms. Care is individualized and phased, with the goal of supporting recovery one system at a time.

Signs You May Benefit from Post-Viral or Long COVID Care

Post-viral illness can affect multiple body systems and often develops gradually after an infection. Many patients seek care when symptoms persist despite normal basic labs or reassurance that recovery “just takes time.”

  • Persistent Fatigue or Exercise Intolerance
    Ongoing post-viral fatigue may reflect mitochondrial dysfunction, immune activation, or impaired oxygen and energy utilization at the cellular level.
  • Brain Fog or Cognitive Difficulty
    Long COVID brain fog can involve slowed thinking, poor concentration, memory issues, or mental exhaustion linked to neuroinflammation or blood flow changes.
  • Shortness of Breath or Reduced Stamina
    Even without lung damage, post-viral autonomic dysfunction or metabolic stress can impair physical endurance and recovery.
  • Dizziness, Heart Rate Changes, or Dysautonomia
    Some patients experience dysautonomia after COVID, including lightheadedness, palpitations, or poor tolerance to standing or exertion.
  • Sleep Disturbance or Non-Restorative Rest
    Post-viral inflammation and nervous system imbalance can disrupt circadian rhythms, leading to unrefreshing sleep.
  • Mood Changes or Increased Anxiety
    Persistent immune activation and nervous system dysregulation can contribute to anxiety, low mood, or emotional volatility after infection.

Our MD-Led Functional Approach

We go beyond symptom management by identifying the physiological drivers of post-viral illness. Our physicians assess how viral exposure has affected immune regulation, inflammation pathways, energy production, and nervous system balance. Your evaluation may include:

  • Inflammatory and immune markers
  • Mitochondrial and metabolic function
  • Autonomic nervous system patterns
  • Hormonal and adrenal response to stress
  • Nutrient deficiencies affecting recovery

  • Gradual improvement in energy and stamina
  • Clearer thinking and improved focus
  • Reduced post-exertional crashes
  • Better sleep quality and stress resilience
