- In adults, however, the same condition results in a different disorder because the growth plates have already closed.

5. **Identify the Adult Condition**: The condition that arises from the hypersecretion of growth hormone in adults is known as acromegaly. This condition is marked by the enlargement of the hands, feet, and facial features.

6. **Conclusion**: Therefore, the abnormal growth of bones due to hypersecretion of growth hormone in adults is known as acromegaly.
