How To Tell If You Have A Thyroid Disorder: Fatigue, Weight Gain And Other Symptoms To Look Out For

If you're feeling irritable, exhausted too hot or too cold your thyroid could be to blame.

The thyroid gland is located in the neck - it produces hormones that affect metabolism and temperature.

When it's not functioning properly, the thyroid gland can become under-active or over-active.

So how can you tell if you're suffering from either?

Hypothyroidism (under-active thyroid):

Symptoms include fatigue, feeling cold, mild weight gain, muscle cramps, dry skin and constipation.

Hyperthyroidism (over-active thyroid):

Symptoms include having an irregular heartbeat, shaking hands and an enlarged thyroid gland. You may also experience sensitivity to heat, unexpected weight loss, a change in menstrual cycle or a drop in libido.

If you think you may be suffering from a thyroid disorder, your GP can give you a blood test or biopsy to assess the functioning of your thyroid.
