Thyroid Basics: How a Small Gland Shapes Your Energy and Mood

The thyroid is a small, butterfly-shaped gland at the front of your neck. It makes hormones that work like a pace setter for your body, guiding how fast you burn energy, how warm you feel, how your heart beats and even how clearly you think. Thyroid problems are common, especially in women, and they are very treatable once they are found.

When the thyroid runs slow

An underactive thyroid can make you feel tired, cold and low in mood. Other signs include weight gain, dry skin, thinning hair, constipation, heavy periods and a slow, foggy feeling. Because these changes come on gradually, many people think they are simply getting older or working too hard.

When the thyroid runs fast

An overactive thyroid speeds things up. You may notice weight loss despite a good appetite, a racing or uneven heartbeat, shaky hands, feeling hot and sweaty, anxiety, trouble sleeping and more frequent bowel movements. Some people also notice a swelling in the neck or changes around the eyes.

Testing and treatment

A simple blood test measures your thyroid hormones and shows whether your gland is working too slowly, too quickly or just right. Treatment depends on the cause. A slow thyroid is usually treated with a daily hormone tablet, while a fast thyroid may be treated with medicine or other options. Regular checks help keep your dose just right.

Everyday habits that support thyroid health

Treatment comes first, and these habits help you feel your best:

• Use iodised salt in moderation
• Eat a varied diet with fish, dairy and eggs
• Take thyroid medicine at the same time each day
• Keep follow-up blood tests on your calendar
• Tell your doctor about new symptoms or medicines
