The answer is E) All of the answers are correct.
Explanation for each option:
A) Cortisol: This hormone is produced by the adrenal glands and plays a significant role in the body's response to stress. It can influence blood glucose levels by promoting gluconeogenesis, which increases blood sugar. High levels of cortisol can lead to fatigue and altered glucose metabolism.
B) GH (Growth Hormone): Growth hormone affects metabolism, including the regulation of blood glucose levels. It can increase blood sugar by reducing the uptake of glucose in tissues and promoting gluconeogenesis and lipolysis.
C) Insulin: Insulin is crucial for regulating blood glucose levels. It facilitates the uptake of glucose into cells, lowering blood sugar levels. Problems with insulin production or function can lead to diabetes, characterized by high blood glucose levels and fatigue.
D) Thyroid hormones: These hormones regulate metabolism and energy levels. Hypothyroidism (low thyroid hormone levels) can lead to fatigue and may affect glucose metabolism, potentially leading to altered blood glucose levels.
Since all these hormones can be related to issues with fatigue and blood glucose levels, the correct answer is E) All of the answers are correct.
