When the thyroid makes more hormone than your body needs, things can speed up. Some people notice a racing heart, restless nights, or periods that get lighter and further apart.
You might notice
- heart racing or skipping for no clear reason
- feeling anxious, jittery or on edge
- trouble sleeping
- losing weight without trying
- feeling hot and sweaty when others aren't
- periods getting lighter or further apart
