How Long Do COVID Symptoms Last?

Introduction: Why COVID Recovery Needs a New Approach

COVID-19 has impacted millions, but for many, symptoms don’t end with a negative test. Fatigue, brain fog, shortness of breath, and lingering inflammation can last weeks or even months—this is commonly referred to as Long COVID or Post-Acute Sequelae of COVID (PASC).

At Patients Medical in New York City, we go beyond symptom management. Our integrative care team combines functional medicine, holistic therapies, and conventional diagnostics to help your body heal completely—restoring energy, immunity, and balance.

What Is Long COVID?

COVID-19 is a viral infection caused by the SARS-CoV-2 virus. While symptoms often resolve in 7–14 days, some individuals—regardless of age or severity—continue to experience symptoms for weeks or even months after initial infection.

Common Timeframes:
  • Acute COVID-19: 1–2 weeks (mild to moderate)
  • Post-COVID Recovery: Up to 4 weeks
  • Long COVID (PASC): Symptoms persisting beyond 4–12 weeks

Common Symptoms of Long COVID:

Symptoms That May Linger in Long COVID

  • Persistent fatigue
  • Shortness of breath or chest tightness
  • Brain fog or memory issues
  • Anxiety, depression, or mood swings
  • Sleep disturbances
  • Palpitations or rapid heartbeat
  • Muscle and joint pain
  • Loss of smell or taste
  • Digestive issues (bloating, IBS-like symptoms)

Root Causes: Why Do COVID Symptoms Persist?

From a functional medicine standpoint, Long COVID is a complex condition involving immune dysregulation, inflammation, and cellular damage. Contributing root causes may include:

  • Inflammatory cytokine storm aftermath
  • Mitochondrial dysfunction leading to fatigue
  • Viral persistence or reactivation (e.g., Epstein-Barr Virus)
  • Leaky gut and microbiome imbalance
  • Autonomic nervous system dysfunction (POTS, HR variability)
  • Hormonal dysregulation (cortisol, thyroid, sex hormones)
  • Toxin buildup or impaired detox pathways

Diagnostic Testing We Use for Long COVID

At Patients Medical, we use advanced diagnostic testing to understand the full scope of your Long COVID symptoms and the factors contributing to your condition. These tests may include:

Inflammatory markers (CRP, ferritin, IL-6)

Immune system panels (CD4/CD8, NK cells, cytokine profiling)

Mitochondrial function and oxidative stress testing

Cortisol and adrenal hormone panels

Gut health panels (stool microbiome, zonulin, candida, parasites)

Nutrient deficiencies (B12, D, magnesium, zinc)

Mold/mycotoxin and heavy metal testing

Epstein-Barr, CMV, and other viral reactivation panels

Integrative Treatments for Long COVID

Nutritional Therapy

  • Anti-Inflammatory Diets: A focus on foods that reduce inflammation and support the immune system, such as leafy greens, fatty fish, and berries.
  • Nutrient-Rich Foods: Incorporating foods rich in vitamins, minerals, and antioxidants to help repair tissue and support overall recovery.
  • Elimination Diets: To identify food sensitivities or allergens that may be exacerbating your symptoms.

IV Vitamin Therapy

  • Vitamin C and Zinc: To support immune function and reduce inflammation.
  • Magnesium and B Vitamins: To address fatigue, muscle cramps, and cognitive issues.
  • Glutathione: A powerful antioxidant to support detoxification and reduce oxidative stress.

Herbal & Nutraceuticals

  • Curcumin (Turmeric): Known for its anti-inflammatory properties, curcumin helps manage inflammation associated with Long COVID.
  • Ashwagandha: An adaptogen that can help reduce stress and support immune function.
  • Probiotics and Prebiotics: To restore gut health, which plays a crucial role in immune function and overall recovery.
  • Omega-3 Fatty Acids: To reduce inflammation and support brain function.

Stress Reduction & Mental Health Support

  • Meditation and Mindfulness: To reduce stress, improve focus, and support emotional well-being.
  • Cognitive Behavioral Therapy (CBT): To help manage anxiety and depressive symptoms related to Long COVID.
  • Acupuncture: To alleviate pain, support energy levels, and promote relaxation.

Hormone Balancing

  • Bioidentical Hormone Replacement Therapy (BHRT): To restore hormonal balance, particularly cortisol and thyroid hormones.
  • Adrenal Support: To help restore adrenal function and manage fatigue.

Real Case Study: Ethan’s Path Back to Wellness

Ethan, age 45, came to Patients Medical three months after recovering from COVID. Despite testing negative, he was plagued by fatigue, brain fog, and chest tightness. He had stopped working and couldn’t exercise.

What We Found:

  • Elevated inflammatory markers
  • Mitochondrial dysfunction
  • Leaky gut and candida overgrowth
  • Low cortisol and low vitamin D

What We Did:

  • Created an anti-inflammatory meal plan
  • IV therapy with glutathione and vitamin C
  • Herbal mitochondrial boosters and adrenal adaptogens
  • Gut healing protocol with probiotics and antifungals

Within 8 weeks, Ethan’s energy returned, his brain fog lifted, and he resumed work and exercise—with a stronger immune system than ever.
