What is a polyendocrine disorder?

• A. Overproduction of a Single Hormone
• B. Decreased Sensitivity of All Target Cells
• C. Hypersecretion or Hyposecretion of More Than One Hormone
• D. Normal Hormone Production

Answer: (C)

Polyendocrine disorders involve multiple endocrine glands, leading to imbalances in more than one hormone. The key idea is that several hormones are out of balance, either up or down, rather than just one. This fits when the underlying problem affects several glands or hormonal pathways, which is why the best description is hypersecretion or hyposecretion of more than one hormone. In real-world contexts, conditions like autoimmune polyglandular syndromes illustrate how multiple hormones can be abnormal at the same time, such as low adrenal hormones alongside thyroid or pancreatic hormone changes. Think of the other options as describing issues that aren’t about multiple hormonal changes: overproduction of a single hormone is a one-hormone, one-gland problem; decreased sensitivity of all target cells points to receptor or signaling issues rather than multiple hormones being imbalanced; normal hormone production isn’t a disorder at all.
