Are You Feeling Constantly Tired or Run Down?

Many people in the UK experience fatigue, unexplained weight changes, low mood, and sometimes even hair loss. If this feels familiar, your thyroid could be playing a role. The NHS reports that thousands live with undiagnosed thyroid conditions, as symptoms often overlap with daily life stresses.

What Does the Thyroid Do, and Why Does It Matter?

Your thyroid is a small gland in your neck, but it regulates vital body processes by releasing hormones that control metabolism, energy levels, and mood. Thyroid-Stimulating Hormone (TSH) is a key signal from your brain telling your thyroid how much hormone to make.

High TSH often means your thyroid is underactive (hypothyroidism). Low TSH can be a sign it's overactive (hyperthyroidism).

Frequently asked questions

What are common symptoms of an underactive thyroid?

Symptoms of hypothyroidism (underactive thyroid) often include tiredness, unexplained weight gain, feeling cold, depressive mood, and hair loss. However, these can manifest differently for each person and can be mistaken for other health issues.

Do I have thyroid issues if I feel fatigued all the time?

Not necessarily. Symptoms of thyroid dysfunction are non-specific and may overlap with other conditions. A blood test measuring your TSH levels is the most reliable way to check if your thyroid is functioning properly.

Can I check my thyroid at home?

Yes, our finger-prick TSH Home Blood Test Kit is a convenient way to check your thyroid function from the comfort of your home with quick results.
