Overactive or underactive

## Accurate, medical-grade thyroid assessment with GP-led interpretation

Thyroid health plays a crucial role in energy, mood, weight regulation, metabolism and hormonal balance. When the thyroid is overactive or underactive, symptoms can often be wide-ranging and difficult to understand without proper testing.

At Dr Paulina Charlesworth Aesthetics in Sevenoaks, Kent, we provide comprehensive thyroid blood testing with GP interpretation, giving you clarity about your thyroid function and personalised guidance on the next steps for your health.

**What Is a Thyroid Test?**

A thyroid test is a simple blood test that measures key hormones responsible for regulating metabolism. We assess the most clinically relevant markers:

- **TSH (Thyroid Stimulating Hormone)**
- **Free T4**
- **Free T3** (if clinically indicated)
- **Thyroid antibodies** (for autoimmune thyroid disease such as Hashimoto’s or Graves’)

This deeper analysis helps identify both obvious and subtle thyroid dysfunction.

**Symptoms of Thyroid Imbalance**

Many people experience symptoms for years without realising the thyroid may be involved. Signs of underactive or overactive thyroid function can include:

**Possible symptoms of an underactive thyroid (hypothyroidism):**

- Unexplained weight gain
- Fatigue or low energy
- Dry skin or thinning hair
- Feeling cold
- Brain fog or difficulty concentrating
- Low mood

**Possible symptoms of an overactive thyroid (hyperthyroidism):**

- Unexplained weight loss
- Heat intolerance
- Anxiety or restlessness
- Heart palpitations
- Difficulty sleeping
- Tremors

If you're experiencing several of these symptoms, a thyroid test can provide essential clarity.
