What If You Caught a Virus and Never Really Got Better?
You know that feeling when you’re almost over a cold but weeks go by and you’re still dragging yourself out of bed, still foggy, still aching? Imagine that feeling lingering not for days but for months or even years. For many Australians, that’s the unsettling reality of Long COVID. But here’s the twist. It’s not entirely new.
There’s a condition that’s been around much longer called Chronic Fatigue Syndrome. The overlap between Long COVID and ME/CFS is more than just coincidence. It points to something deeper that conventional medicine is only just starting to recognise.
What Do Long COVID and Chronic Fatigue Have in Common?
Both Long COVID and CFS fall into a category known as post-viral syndromes. That means they often begin after someone catches an infection, like a bad flu, glandular fever or COVID. Instead of making a full recovery, the body seems to stay stuck in survival mode.
Here’s what that can look like:
- Crushing fatigue that doesn’t improve with rest
- Brain fog that makes simple thinking feel like climbing a mountain
- Muscle and joint pain for no clear reason
- Unrefreshing sleep that leaves you just as tired in the morning
- Gut issues, breathlessness, dizziness or strange sensations
If that sounds familiar, you’re not alone. These symptoms are showing up in people with both Long COVID and CFS, and that’s because the biological patterns underneath are often very similar.
What’s Really Going On Inside the Body?
While the symptoms might seem vague or hard to pin down, under the surface, there’s a lot happening. Functional medicine takes a closer look and here’s what we often find:
- Mitochondrial Dysfunction
Mitochondria are the tiny power plants inside your cells. They create energy that your body uses to think, move and repair. In people with Long COVID or ME/CFS, these mitochondria may not be working properly. The result is constant fatigue, even after rest or sleep.
- Immune Confusion
Your immune system is meant to fight off infections, then settle down. But in post-viral conditions, it often stays overactive or swings the other way and becomes underactive. That creates a mix of chronic inflammation, poor defences and sometimes even autoimmunity, where the body attacks its own tissues.
- Chronic Inflammation
Inflammation is a normal part of healing, but when it doesn’t switch off, it causes damage. In both Long COVID and CFS, low-level inflammation lingers. It can affect the brain, gut, muscles and mood.
Why Conventional Medicine Often Misses It
Here’s something many people don’t realise. Most mainstream doctors are trained to look for disease using standard blood tests and scans. If nothing obvious shows up, they might say you’re fine, or that it’s just anxiety or stress.
But here’s the problem. Those tests often don’t show subtle dysfunctions in mitochondria, the immune system or inflammation levels. So you’re left with symptoms, but no answers. It can feel invalidating and frustrating.
This isn’t because doctors don’t care. It’s because the tools they’re given aren’t built to see the deeper issues that functional medicine focuses on.
How Functional Medicine Finds the Root Cause
Instead of chasing symptoms, we ask a different question. Why is the body struggling in the first place?
Functional medicine uses more comprehensive testing to find what’s really driving the exhaustion. Here are just some of the tools we use:
- Immune system panels to look for hidden viral triggers, inflammation or autoimmune markers
- Gut microbiome assessments to spot imbalances that may be disrupting immune health
- Hormone panels to explore adrenal and thyroid function
- Nutrient testing to detect deficiencies that can drain your energy
Instead of guessing or dismissing your symptoms, we connect the dots. We build a picture of your body’s unique biology, then work with you to restore balance.
Real People, Real Results
Many of the people I’ve worked with have been dealing with unexplained fatigue for months, sometimes years. They’ve seen GPs, specialists and even psychologists. They’ve been told to wait it out or manage their stress.
But when I dig deeper, I often find:
- Reactivated viruses like Epstein-Barr
- Gut bacteria that are out of balance and triggering inflammation
- Mitochondria under stress and not producing enough energy
- Hormone imbalances affecting sleep and recovery
With a tailored approach, based on what your body actually needs, things start to shift. Fatigue improves. Brain fog clears. You feel like yourself again.
Will Long COVID Turn Into CFS?
It’s a big question. Not everyone who has Long COVID will develop chronic fatigue syndrome, but many of the risk factors are similar. In some cases, Long COVID seems to be activating the same biological pathways as CFS. For others, it may be revealing an underlying issue that was already there.
Either way, we know this. Post-viral fatigue is real. It’s not just in your head. And it deserves proper care and understanding.
Don’t Wait for It to Get Worse
If you’ve been told everything looks normal, or you just need more rest, please know there’s more to the story. Your symptoms are telling you something, even if your test results haven’t.
With a functional medicine lens, we go beyond the surface to explore how your body is actually functioning. Not just in parts, but as a whole.
