What physiological pathology arises directly from a severe lack of dietary carbohydrates?
Show answer Hide answer
Answer: B. Hypoglycemia
Explanation
Severe carbohydrate restriction depletes liver and muscle glycogen stores, leading to dangerously low circulating blood glucose concentrations. The brain relies almost exclusively on glucose for fuel, making adequate carbohydrate availability critical for preventing neurological dysfunction. Hypoglycemia causes acute symptoms such as dizziness, confusion, tremors, and severe fatigue when dietary carbohydrate intake fails completely. Glucose is the primary metabolic fuel source for the central nervous system and red blood cells under normal conditions. When dietary carbohydrates are absent, the body attempts to compensate through gluconeogenesis using amino acids and glycerol. Hypoglycemia is clinically defined as a blood glucose concentration falling below normal healthy physiological thresholds.
Hypertension refers to chronically elevated arterial blood pressure rather than a metabolic pathology caused by dietary carbohydrate deficits. Scurvy is a deficiency disease caused specifically by a severe lack of dietary vitamin C, not carbohydrate restriction. Rickets is a childhood bone disorder caused by a lack of vitamin D, calcium, or phosphate absorption.
