What is a common symptom of low blood sugar (hypoglycemia)?

• A. Fever
• B. Loss of appetite
• C. Irritability and change in personality
• D. Increased thirst

Answer: (C)

Irritability and changes in personality are common symptoms of low blood sugar, also known as hypoglycemia. When blood sugar levels drop, the brain does not receive enough glucose, which is its primary source of energy. This can lead to neurological symptoms, including mood swings, irritability, confusion, and changes in personality. Individuals may become anxious, irritable, or experience difficulty concentrating. Recognizing such symptoms is crucial, as hypoglycemia can lead to severe complications if not managed promptly. In this context, symptoms like fever, loss of appetite, and increased thirst are less directly associated with low blood sugar. Fever typically indicates an infection or inflammation, while loss of appetite can arise from various conditions but is not a specific sign of hypoglycemia. Increased thirst is commonly associated with high blood sugar levels, as seen in conditions like diabetes, rather than low blood sugar. Thus, irritability and changes in personality are more characteristic of the brain's response to insufficient glucose availability.
