The thyroid, also referred to as a thyroid gland, is found in the neck, behind a cartilage known as an 'Adam's apple'. The thyroid is responsible for producing hormones which control metabolism and affect bodily growth rates and other functions. Your thyroid therefore plays an important role when it comes to your health. An imbalance of thyroid hormones can strongly affect your wellbeing. 

There are several, broad symptoms related to thyroid dysfunction. If you are noticing any of these, you should get tested for thyroid disorders.

Signs of an overactive thyroid - hyperthyroidism

  • Sudden weight loss
  • Fatigue
  • Mood swings, anxiety
  • Diarrhoea
  • Palpitations
  • Menstruation and fertility changes
  • Heat sensitivity
  • A swollen neck (enlarged thyroid gland)
Signs of an underactive thyroid - hypothyroidism
  • Weight gain
  • Low energy
  • Being sensitive to the cold
  • Feeling depressed
  • Dry and scaly skin
  • Aches and pains of muscles
  • Menstruation and fertility changes


When a patient presents a number of symptoms that are a strong indicator of hormone imbalance, a thyroid function screening is a necessary part of the diagnostic process.

Both of our clinics provide thyroid function tests with results available in 4 – 12 hours.

If you have had a consultation with us, a doctor will call you to discuss your results and next steps.

If you have not had a consultation and your results are abnormal, we would recommend that you take your results to your GP or return to our clinic for a consultation.
