Doc Talk #96 – Thyroid



In this show, Dr Dan and Jamieson demystify the thyroid gland.

It is a critically important organ that regulates and affects virtually every other part of the body, including other organs, the immune system and metabolism.

We talked about how the thryoid hormones (T3 and T4) are regulated by thyroid-stimulating hormone (TSH).


Having a low (underactive) thyroid is one of the commonest problems (much commoner than an overactive thyroid).

Symptoms of underactive thyroid can be somewhat vague include: fatigue, constipation, depression, carpal tunnel syndrome, menstrual disturbance, neck swelling, dry skin and hair thinning.

We talked about risk factors for thyroid disease, screeening and treatment of thyroid disorders. We also discussed the phenonemon of subclinical hypothyroidism.

The blood test for thyroid disease is quick, easy and inexpensive – so if you are worried about your thyroid it might be worth getting it checked.

Avoiding obesity and staying physically active, ensuring a good diet can help to minimize the impact of any thyroid problems.
