Which condition is a known stimulant of growth hormone secretion?

• A. Hypoglycemia
• B. Hyperglycemia
• C. Vitamin C deficiency
• D. Dehydration

Answer: (A)

Low blood glucose triggers a rise in growth hormone to help restore energy balance. When glucose is scarce, the hypothalamus increases GHRH release and reduces somatostatin, prompting the pituitary to secrete more growth hormone. The GH then promotes fat breakdown and liver glucose production, helping to raise blood sugar and provide energy to tissues. The other options don’t have this direct stimulatory effect: high blood glucose tends to suppress GH release, while vitamin C deficiency or dehydration are not known to specifically stimulate GH secretion.
