Thyroid screening: when should you get checked?

The thyroid regulates metabolism, energy and heart rate. When it works too much or too little, the body shows many uncomfortable changes.

Fatigue, unusual weight gain or loss and a fast heartbeat may relate to the thyroid. Hormone tests help a doctor assess its function.

A thyroid ultrasound detects nodules, most of which are benign but need monitoring. Not every nodule needs intervention.

If your family has a history of thyroid disease, discuss it to get appropriate screening.
