Hyperthyroidism
An overactive thyroid gland
Hyperthyroidism speeds up metabolism. The heart may beat faster, sleep can suffer, and weight may drop without trying. Some people notice symptoms suddenly; others over weeks.
What you should know
- Graves’ disease is a common cause in younger adults.
- Untreated hyperthyroidism can strain the heart and bones.
- Treatment options depend on cause and may include medication or specialist referral.
Symptoms people often report
- Rapid or pounding heartbeat
- Unplanned weight loss
- Sweating more than usual
- Shaky hands
- Anxiety, irritability, or poor sleep
Practical next steps
Seek medical review if you have a fast pulse with weight loss and nervousness. A thyroid blood panel will clarify whether hyperthyroidism is present.
