Pull up a chair. Let’s talk about one of the most common questions in the Hashimoto community.
You Know That Moment?
You’re sitting at the kitchen table.
Maybe the dishes are done, maybe they’re not.
You have a cup of tea in front of you and suddenly that question pops up again.
“Did it start because of that period in my life?” I hear it so often in our Hashi Kitchen community.

“It started after my pregnancy.”
“Everything shifted when I was caring for my dad.”
“I was running on empty at work… and then my hair started falling out.”
These thoughts make sense. When two big things happen close together, our minds naturally connect the dots. That’s human. And honestly? I connected those dots too.
The Question We All Ask
The claim is simple, and you see it everywhere:
“Stress causes Hashimoto.”
Or more gently:
“I think stress triggered mine.”
And I understand why that feels true.
So many of us can point to a time when our body started acting differently. A period of grief. A difficult birth. Burnout. Months where you were barely holding it together. From your own experience, the link is there and that experience matters. Always.
At the same time, I want to make space for something else too. What do we actually know right now?
What We Do And Don’t Know Yet
Researchers agree on one thing: stress and Hashimoto often show up together. In studies, many people report a stressful period before their diagnosis. And there is a logical reason why scientists are interested in that connection.
Stress activates your body’s stress response system. It increases the production of cortisol and other hormones that influence immune function. Because the immune system and nervous system are closely connected, researchers believe that long periods of chronic stress may affect inflammation and immune regulation in some people.
In theory, that could play a role in autoimmune processes.
But, and this is important, most studies cannot prove that stress causes Hashimoto. They can only show that the two often appear together.
It’s a bit like rain and umbrellas. You often see them at the same time, but the umbrella doesn’t cause the rain. They’re both connected to the weather.
Hashimoto appears to develop through a combination of factors including genetics, immune function, hormones, environmental influences, possible infections, nutritional status and potentially stress.
So stress probably isn’t the whole story. But it may be one chapter.
What’s Still Unanswered
This is where things become especially interesting. There are still many questions researchers cannot answer.
Can stress accelerate a process that was already developing?
Does everyone respond to stress in the same way?
Does chronic stress have a different impact than a single traumatic event?
And is stress more involved in symptom severity than disease development itself?
At the moment, we simply don’t know.
Another challenge is that Hashimoto often develops slowly. Some people have thyroid antibodies for years before symptoms appear. Others may have ongoing thyroid damage long before diagnosis. So when someone receives a diagnosis shortly after a stressful life event, it doesn’t necessarily mean the disease started at that moment.
That doesn’t make their experience less real. It simply makes the story more complicated than we sometimes wish it was.
My Own Story
For a long time, I was convinced stress caused my Hashimoto.
It felt obvious.
I was working a lot, travelling frequently and sleeping too little. At the same time, I was dealing with one of the hardest periods of my life after losing my dog. He meant the world to me.
Not long after, my hair started thinning. My energy dropped. My body felt different.
Connecting those events felt completely logical.
Now, looking back, I see it differently.
Could stress have played a role?
Maybe.
Could it have made existing symptoms worse?
Possibly.
Could it have brought something to the surface that was already happening in the background?
That feels most likely to me.
What I do know is this:
Simply stressing less never cured my Hashimoto. But taking care of my nervous system helps. Resting helps. Setting boundaries helps. Being kinder to my body helps. And that distinction matters.
Let’s Keep Discovering Together
So where does that leave us?
Many people feel that stress and Hashimoto are connected, and that feeling deserves space. Science also sees that they often appear together.
But a direct cause?
We can’t say that yet. Maybe stress isn’t the whole book. But it’s a page worth reading.
For The Kitchen Table This Month
I’m curious about your story.
Do you remember a stressful period before your symptoms started? Or does that connection not feel clear for you at all?
There are no right or wrong answers here. Every story adds another piece to the conversation.
And before we leave the table, I’d love to give you a small challenge.
This month, I’m paying a little more attention to the moments when I feel rushed, overwhelmed or tense. Not to fix them. Not to judge them. Just to notice them.
Maybe you’ll join me.
Because sometimes understanding ourselves starts with paying attention. Pour another cup of tea and we’ll keep exploring together. Perhaps that’s what Hashi Kitchen is really about.
Not having all the answers. But creating a place where we can ask better questions together.
With love,
Pam 🤍
