What Are the Symptoms of Thyroid Problems?
The symptoms of thyroid problems include feeling tired, weight changes, a racing or slow heartbeat, mood swings, hair loss, and feeling too hot or too cold. The American Thyroid Association says 20 million Americans have a thyroid issue, and 60% have no idea.
Where Your Thyroid Sits
Your thyroid is a small, butterfly-shaped gland at the front of your neck. It makes hormones that control your heart rate, energy, weight, and body temperature. When it slows or speeds up, your whole body feels it.
Signs of an Underactive Thyroid (Hypothyroidism)
This is the most common thyroid problem. The gland makes too little hormone, so everything slows down. Hashimoto’s, an autoimmune disease, is the top cause.
Watch for:
- Feeling tired after a full night of sleep
- Weight gain without eating more
- Always cold, even in a warm room
- Dry skin and brittle hair
- Constipation, sad mood, or brain fog
- Slow heartbeat
Women over 60 are at the highest risk. NHANES data shows 1 in 8 American women will get a thyroid problem in her lifetime.
Signs of an Overactive Thyroid (Hyperthyroidism)
When the thyroid makes too much hormone, your body runs in overdrive. Graves’ disease is the top cause.
Common signs:
- Fast or pounding heartbeat
- Weight loss without trying
- Feeling shaky, anxious, or jumpy
- Sweating and hot flashes
- Trouble sleeping, loose stools
- Bulging eyes (with Graves’)
When to Call 911
Very high fever with a racing heart could be a thyroid storm. Rare but life-threatening.
Other Warning Signs
A lump in your neck, trouble swallowing, or a lingering hoarse voice may point to a goiter or nodule. The NCI estimates 45,240 new thyroid cancer cases in 2026, mostly in women.
