4. **Recognize Symptoms of Hyperthyroidism:**
- Common symptoms include nervousness, anxiety, mood swings, irregular heartbeat, and weight loss. These symptoms arise due to increased metabolism caused by excess thyroid hormones.

5. **Conclude with the Correct Answer:**
- Based on the understanding that excess thyroid hormones lead to hyperthyroidism, the correct answer to the question is **hyperthyroidism**.

**Final Answer:**
