Question:medium
Growth hormone level is decreased in?
Growth hormone level is decreased in?
Show Hint
Hypoglycaemia, fasting and exercise all raise GH; only one phase of sleep lowers it.

- Hypoglycemia
- Fasting
- Sleep
- Exercise
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: To answer, identify which of the four conditions lowers rather than raises GH output. GH is a classic stress and energy-mobilising hormone.
Step 2: Low glucose (hypoglycaemia), the fasting state, and physical exercise are all powerful physiological stimuli that drive GH release, because the body needs GH to mobilise fat and spare glucose.
Step 3: Sleep is the odd choice. Although deep slow-wave (N3 NREM) sleep gives a major GH peak, the REM phase of sleep actually reduces GH secretion. The exam treats the sleep option as the phase that lowers GH, making it the only condition associated with a decrease.
Step 4: Eliminating the three known stimulators leaves sleep as the answer.
\[\boxed{\text{Sleep}}\]
