What condition is characterized by enlargement of the bones of the hands and feet as a result of excess growth hormone?

1. Acromegaly

2. Dwarfism

3. Gigantism

4. Hypoplasia

The correct answer is: Acromegaly

Acromegaly is a condition that arises from excess growth hormone, typically due to a benign tumor on the pituitary gland. This overproduction of growth hormone leads to the abnormal enlargement of bones and tissues, particularly in the hands and feet, as well as facial features. Patients with acromegaly often experience noticeable changes in their appearance over time, such as enlarged hands, feet, and thickened skin, which are key indicators of the condition. In contrast, dwarfism refers to a condition where a person is significantly shorter than the average height due to genetic or medical reasons, but it does not involve excess growth hormone. Gigantism is similar to acromegaly but occurs in children and adolescents when growth hormone levels are excessively high before the growth plates close, leading to overall larger body size rather than localized enlargement. Hypoplasia refers to underdevelopment or incomplete development of a tissue or organ, which is not related to growth hormone levels or bone enlargement. Thus, the characteristic features of acromegaly, including the specific enlargement of bones in the hands and feet due to excess growth hormone, clearly identify it as the correct answer in this scenario.
