Are We Genetically Destined To Get MECFS?

Last night I was visiting with my niece and nephew as I roll through the Deep South. My brother’s kids are like my own, and I adore watching them grow into ever-increasingly magical humans. My nephew was so eager to show me his latest passion—hand-painting Warhammer figurines with tools almost invisible to the naked eye. He’s incredible at it, I might add. My niece is an avid reader, equally eager to show me her ever-growing collection of books. 

And it’s no wonder they both have such a flair for creativity and language. Their parents are artists, their grandparents were artists… and I myself am an artist, writer, and poet. It runs in the family.

That’s the beauty of genetics. They are a blueprint that connects families across generations. Nature tells us who we might be—and nurture allows it to be expressed.

And naturally, this got me thinking about ME/CFS. Specifically, a question that’s been debated a lot—especially since the DecodeME study came out in 2025:

Are we genetically destined to become sick with ME/CFS?

Let’s talk about it.

The DecodeME study was the largest genetic study on ME/CFS to date, and I think we can all agree it was incredibly validating for our community. It showed—finally, through genetic markers—that ME/CFS is not a psychological illness, as it’s been misdiagnosed for so long, but a very real biological neuroimmune condition. That was a huge step forward, especially given how many of us have experienced some form of medical gaslighting due to the lack of understanding in the medical field.

But that’s not the only reason this study was so important.

It was also important because the findings—stay with me here—point toward something else: a kind of blueprint… or roadmap… for how we might actually move out of this state. Not a cure, at least not yet, but a pathway toward healing.

And this is the part I see almost no one talking about. There’s so much focus on how it validates the illness—which it absolutely does—that we’re missing how it might also illuminate a path forward.

When the study came out, I was already three years into sustained recovery. And I watched how people responded. For some, learning about a genetic predisposition felt like a door closing—as if identifying these markers meant recovery wasn’t possible.

But for me, it did the opposite. It validated a path I had already walked. It gave language—and biology—to something I had already lived.

When you zoom out and look at what they found, you see eight genetic regions. But more importantly, you see patterns—three major ones.

The first is immune system reactivity. The body may respond more strongly or differently to infections, which aligns with how many people develop ME/CFS after a virus.

The second is energy and cellular stress—meaning the body may struggle more with producing and sustaining energy, and recovering after exertion. That maps closely to fatigue and post-exertional malaise.

And the third is nervous system and pain processing—heightened sensitivity to light, sound, touch, and stress, often alongside amplified pain. For me personally, that sensitivity existed long before I ever got sick.

When you put those pieces together, you’re looking at a system that is more reactive to infection, less resilient under stress, and more neurologically sensitive.

And yet—this part is just as important—Those same genetic patterns also exist in people who never go on to develop ME/CFS. 

So what we’re talking about here isn’t destiny. It’s predisposition.

I actually think genetic acceptance is an important part of this journey. I fully accept that I have always had—and still have—that predisposition. The genetics are what they are. But the activation of ME/CFS—that’s epigenetics.

One is a given. One is not. And if genes can be turned on, then they can also be turned off.

So maybe, just maybe - as a community, we’re missing something important here. Yes, we absolutely need more research, better treatments, and more visibility in the medical world. But in the meantime, we also have more to work with than we think.

Because if this study shows us how ME/CFS is expressed—through the immune system, energy systems, and nervous system—then it’s also showing us what needs support.

So the question becomes: Can we support those systems in a way that allows the body to come back into balance?

My lived experience says yes. And for me, that looked like this:

Supporting my immune system and reducing viral and biotoxic load—that became Pillar 3.

Learning how to work with my energy instead of constantly pushing past it—that became Pillar 2, because energy can rebuild… but not if you keep exceeding your limits.

Helping my nervous system become less reactive, less sensitized, and more regulated—that became Pillar 1.

And then there was the final layer—one I didn’t expect.

Once a system becomes that sensitive, how you live your life matters. Your boundaries, your relationship to stress, your attachment patterns. That became Pillar 4.

Of course, it’s more nuanced than this. But in a nutshell, this is how I found my way out—and how I help others find theirs.

It’s been eight years since I first got sick, and three years since I got well. I feel confidently recovered—not because the genes disappeared, but because I understand what they mean for me and how to work with them.

So when I look at the DecodeME study now, I don’t see a life sentence.

I honestly just see the truth. 

Yes, my body was triggered by a virus and responded in a very real, biological way. But also that the body is intelligent, and capable of coming back into balance when given the right support.

If that resonates, beautiful. If it doesn’t, that’s okay too.
