If insulin-stimulated glucose uptake in skeletal muscle cells is chronically impaired, which consequence follows regarding pancreatic beta cell function?

💡 Explanation

Chronic insulin resistance in skeletal muscle increases demand on pancreatic beta cells to secrete more insulin to maintain glucose homeostasis. Consequently, beta-cell hyperplasia and hypertrophy occurs via compensatory mechanisms, rather than decreased function. This happens because the cells are attempting to overcome peripheral resistance, therefore beta-cell sensitivity to somatostatin is not increased.

• Why does an elderly patient with diminished kidney function and reduced sensitivity to thirst experience a higher risk of dehydration when prescribed diuretics for hypertension?
• Why does collagen deposition in arteries increase with age?
• Why does the liver sometimes fail to properly digest fats following gallbladder removal?
• If an axon terminal continuously releases acetylcholine but the postsynaptic receptors are dysfunctional, which consequence follows for muscle fiber contraction?
• Why does long-term vaccine efficacy against a virus often rely on repeated exposures rather than a single dose?
