What Is Long COVID and Why Did I Get It?

Long COVID, also known as post-acute sequelae of SARS-CoV-2 (PASC), describes symptoms that continue long after the initial infection has passed. While some people bounce back quickly, others experience lingering issues that affect energy, focus, and overall health.

COVID-19 can impact far more than the lungs. It influences the immune system, nervous system, cardiovascular function, and even how your cells produce energy. For some individuals, the infection disrupts these systems in a way that doesn’t automatically reset.

Instead of returning to normal, the body may remain stuck in…

  • A heightened inflammatory state
  • Ongoing immune activation
  • Impaired mitochondrial (energy) function
  • Hormonal and stress-response imbalances

While anyone can contract Long COVID, certain individuals may be at higher risk, including those with a history of chronic inflammation, autoimmune conditions, or underlying issues such as gut dysfunction, hormone imbalances, or nutrient deficiencies. People who experienced a more severe COVID infection, high stress levels, or poor recovery during or after illness may also be more susceptible.

Isn’t COVID Over? Why Do I Still Feel This Way?

Even though COVID may feel like it’s been “over” for a while, your body may still be dealing with the aftermath of a strong infection.

In some cases, the body doesn’t fully shut off its defensive response. Instead, it stays in a cycle of…

  • Chronic inflammation
  • Immune overactivity
  • Nervous system dysregulation
  • Poor recovery and energy production

This is why you might feel exhausted after minimal effort, struggle with focus, or notice symptoms that come and go unpredictably. At in2GREAT in Overland Park, we help patients understand that this isn’t something you need to just “push through.” It’s a physiological pattern that can be addressed with the right strategy.

Common Symptoms of Long COVID

Long COVID can affect multiple systems in the body, which is why symptoms often feel wide-ranging and difficult to pin down.

This goes beyond normal tiredness. It’s a deep, ongoing exhaustion that doesn’t improve with rest and can worsen after activity.

Many patients experience trouble concentrating, memory lapses, and slower thinking. Tasks that once felt simple can become frustrating.

You may feel winded more easily or notice that your physical capacity has decreased.

Dizziness, irregular heartbeats, and symptoms of dysautonomia can indicate nervous system involvement.

Inflammation can lead to lingering aches, stiffness, and discomfort throughout the body.

Difficulty falling asleep, staying asleep, or waking up refreshed can further compound fatigue.

Frequent or persistent headaches are common, often tied to inflammation and vascular changes.

Bloating, food sensitivities, and irregular digestion may develop as gut health becomes disrupted.

Anxiety, irritability, or low mood can occur due to the connection between inflammation and brain chemistry.

If you’re experiencing symptoms across multiple systems, it’s a sign that your body needs a comprehensive, root-cause approach, not isolated treatments.

Discover the Functional Medicine Approach to Long COVID Recovery

At in2GREAT Functional Medicine in Overland Park, we focus on identifying and correcting the underlying imbalances driving your symptoms. Dr. Priest and his team build personalized plans designed to reduce inflammation, restore energy, and support long-term healing.

We start by understanding your full health history and symptoms. Advanced testing helps uncover hidden issues such as immune dysfunction, nutrient deficiencies, and inflammation markers.

Since inflammation is central to Long COVID, we use targeted nutrition, supplementation, and lifestyle strategies to calm the body and promote healing.

Rather than simply boosting the immune system, we work to balance it. This may include addressing lingering viral activity or immune overactivation.

Fatigue often stems from poor cellular energy production. We support mitochondrial function so your body can produce and sustain energy more effectively.

Many Long COVID symptoms are tied to a dysregulated nervous system. We incorporate strategies to improve stress response and help your body shift out of “fight or flight.”

The gut plays a major role in inflammation and immunity. We address imbalances in the microbiome to support whole-body healing.

Hormones such as cortisol and thyroid hormones can be disrupted after illness. Restoring balance can significantly improve energy, mood, and resilience.

Recovery isn’t about pushing harder — it’s about working with your body. We guide you through realistic, sustainable changes that support long-term improvement.

This approach is personalized, strategic, and designed to help your body recover in a way that lasts.

Beyond Long COVID: We Address Other Causes of Chronic Inflammation

While Long COVID is a common trigger, it’s not the only cause of chronic inflammation.

We also evaluate for other contributing factors, including the following:

  • Chronic Inflammatory Response Syndrome (CIRS)
  • Lyme disease and co-infections such as Bartonella
  • Mold exposure and biotoxin illness
  • Hidden infections
  • Environmental toxins

In some cases, COVID may have been the tipping point — but other underlying issues may still be driving symptoms. By identifying and addressing these factors, we can help you achieve more complete healing. Even if your symptoms didn’t start with COVID, the same functional medicine approach can help restore energy, reduce inflammation, and improve how you feel day to day.
