The symptoms of thyroid disorders include fatigue, weight gain or loss, mood swings, hair thinning, dry skin, a racing or slow heartbeat, and feeling too hot or too cold. The American Thyroid Association says 20 million Americans have a thyroid disorder, and 60% have no clue.
What Your Thyroid Does
Your thyroid is a small, butterfly-shaped gland in your neck. It makes hormones that run metabolism, heart rate, mood, and body temperature. When it acts up, you feel it everywhere.
Symptoms of an Underactive Thyroid
Hypothyroidism is the most common thyroid disorder. Hashimoto’s, an autoimmune disease, is the top cause.
Common signs:
- Tired all the time, even after sleep
- Weight gain without eating more
- Cold hands and feet
- Dry skin, brittle hair
- Constipation, brain fog, low mood
- Slow heartbeat
A Note for Women
Women are 5 to 8 times more likely than men to have thyroid issues. NHANES data shows 1 in 8 American women will get a thyroid disorder. Risk climbs after pregnancy and after 60.
Symptoms of an Overactive Thyroid
Hyperthyroidism happens when the gland pumps out too much hormone. Graves’ disease is the top cause.
Common signs:
- Fast or pounding heartbeat
- Weight loss without trying
- Shaky hands, anxiety
- Sweating, feeling hot
- Trouble sleeping, loose stools
- Bulging eyes (Graves’)
When It Becomes an Emergency
Very high fever plus a racing heart could be a thyroid storm. Rare but life-threatening. Head to the ER.
Other Thyroid Disorders to Know
A lump in your neck, trouble swallowing, or a lasting hoarse voice can mean a goiter or nodule. The NCI estimates 45,240 new thyroid cancer cases in 2026, mostly in women.
