Hypothyroidism during adulthood can lead to which of the following disorders?

Myxedema is a severe form of hypothyroidism that can occur in adults. When the body is deficient in thyroid hormones, it can lead to a range of serious health issues, including myxedema. This disorder is characterized by a buildup of mucopolysaccharides in the skin and other tissues, resulting in symptoms such as swelling, particularly in the face, hands, and feet, as well as other systemic effects such as lethargy and intolerance to cold.

Hypothyroidism disrupts the normal metabolic processes in the body, leading to a slower metabolism and impaired regulation of various bodily functions. As the condition progresses, if left untreated, it can culminate in myxedema, which is often considered a medical emergency.

In contrast, other options listed, such as acromegaly and Graves' disease, are directly related to conditions of excess thyroid hormone or growth hormone rather than deficiencies. Hypoglycemia, while a significant concern in various contexts, does not specifically correlate with hypothyroidism.
