Could Your Symptoms Be Thyroid-Related?

Fatigue that won't budge, weight changes without clear reason, mood swings, or sensitivity to cold—these are common complaints in the UK, especially as we lead busy lives. But when these symptoms persist, could your thyroid be to blame?

What Is the Thyroid and Why Is Free T4 Important?

Your thyroid is a small gland in your neck, playing a big role in regulating your metabolism through hormones—primarily thyroxine (T4) and triiodothyronine (T3). 'Free T4' refers to the unbound, active form of thyroxine that your body can use immediately.

Subtle but persistent symptoms may point towards a thyroid imbalance. Testing your Free T4 at home could offer clarity and peace of mind.

What Else Could Cause These Symptoms?

Many UK adults experience stress, poor sleep, or dietary deficiencies that can mimic thyroid symptoms. However, if these persist despite lifestyle changes, it's worth testing your thyroid health.

When should I consider a thyroid test at home?
