What determines the severity of hypoglycemia in a child?

• A. Blood glucose level
• B. Time of day
• C. Temperature
• D. Parental age

Answer: (A)

Severity is determined by how low the blood glucose level drops. When glucose in the blood falls, the brain loses its main energy source, leading to neuroglycopenia that progresses from mild symptoms (irritability, pallor, tremor) to more serious signs (confusion, seizures, coma) as the nadir becomes deeper. The rate and duration of the drop can influence how quickly and severely symptoms appear, but the absolute glucose level is the primary factor setting how severe the hypoglycemia will be. Factors like time of day, ambient temperature, or parental age don’t determine the severity of the low blood sugar itself, though they can affect recognition or triggering conditions.
