Which of the following is NOT a common symptom of hypoglycemia?

In the context of hypoglycemia, increased appetite is not recognized as a common symptom. Hypoglycemia, or low blood sugar, typically provokes a range of physiological reactions as the body attempts to correct the glucose deficiency. Common symptoms include shakiness, sweating, and irritability, which are all responses driven by the body’s release of adrenaline and other hormones in an effort to raise blood sugar levels.

Shakiness occurs as the nervous system responds to low glucose, causing tremors and involuntary muscle contractions. Sweating is another physiological reaction attributable to adrenaline release, as the body becomes anxious about its energy levels. Irritability may surface due to the brain's reliance on glucose for energy; a lack of glucose can adversely affect mood and cognitive function.

Increased appetite, while it might occur as a compensatory mechanism in other scenarios, is not a typical signal of hypoglycemia and does not fit the acute physiological responses defined by this condition. Instead, individuals experiencing hypoglycemia might have cravings for sugar, but they wouldn’t generally describe this experience as a symptom of hypoglycemia itself.
