The Gut Thyroid Connection: What You Need to Know.

The gut thyroid connection – the surprising link between your thyroid & gut – and why it matters more than you think.

Thyroid issues are incredibly common – yet around 60% of people struggling with thyroid dysfunction don’t even know it. Why? Because the symptoms are often vague, easily confused with other health concerns, or brushed off as just “being tired” or “getting older.”

But here’s something not enough people are talking about:

👉 Your thyroid and your gut are deeply connected.

In this article, you’ll discover 5 powerful ways your gut health and thyroid function are linked – and why supporting one can make a huge difference to the other.

1. The Gut Thyroid Connection – Your Thyroid Controls Gut Function

Your thyroid hormones play a big role in how your digestive system works. When thyroid function is low (hypothyroidism), everything slows down – including your gut.

That means slower movement through the digestive tract, sluggish digestion, and yes… constipation.

2. Thyroid Health Shapes Your Microbiome

When considering the gut thyroid connection, an underactive thyroid doesn’t just affect motility – it can mess with your gut bacteria, too.
Slower digestion changes the environment in your intestines, which can throw off the balance between beneficial and harmful microbes.

Why does this matter? Because your gut flora is a key player in overall health – from immunity to mood and more.

If you’re worried about your gut health, I’d highly recommend downloading my online course The Ultimate Gut Health Programme to help support your digestive system, whilst avoiding triggering symptoms.

It’d be impossible to include all you need to know in one blog, but the programme will have all you need to know to ensure you’re soothing your digestive system, whilst eating delicious and filling foods.

4. Your Gut Helps Activate Thyroid Hormones

Here’s a fun fact:
🧬 About 20% of your T4 hormone is converted into active T3 by your gut bacteria.
That means your thyroid needs a healthy gut to do its job properly.

If you’re dealing with IBS, constipation, Coeliac disease or any gut imbalance, your body may not be converting enough thyroid hormone to keep you feeling energised and well.

✨ Bottom line?

If you’re struggling with thyroid symptoms – fatigue, weight gain, brain fog, low mood – don’t ignore your gut.

And if your digestion is off track, it could be time to check in with your thyroid.
