Developmental delay, hypogonadism, and olfactory or taste loss stem from a deficiency of_______________?
Show answer Hide answer
Answer: B. Zn
Explanation
Zinc deficiency leads directly to developmental delay, hypogonadism, and sensory impairments like taste loss. Zinc plays an essential catalytic and structural role in numerous enzymatic reactions necessary for growth. Inadequate nutritional intake or malabsorption syndromes precipitate these characteristic clinical deficiency signs. Zinc is an essential trace mineral required for cellular metabolism, immune function, and protein synthesis. Loss of taste acuity, known as hypogeusia, is a well-documented early clinical indicator of zinc depletion. Pediatric growth retardation and delayed sexual maturation occur during prolonged severe nutritional deficiency.
Nutritional counseling and dietary supplementation quickly reverse symptoms associated with mild zinc deficiency. Healthcare providers evaluate trace mineral levels in patients experiencing unexplained developmental delays. Understanding micronutrient roles prevents diagnostic oversights in patients presenting with atypical sensory losses. Copper deficiency typically causes anemia and neurological abnormalities rather than primary taste and growth loss. Potassium is a major intracellular electrolyte essential for cardiac function, not developmental growth. Chromium deficiency primarily impairs glucose tolerance and insulin metabolism rather than taste or gonadal function.
