Which age-related change is associated with absorption changes and risk for gallstones?

• A. Cardiac Hypertrophy
• B. GI Tract Changes
• C. Decreased GFR
• D. Osteoporosis

Answer: (B)

Age-related changes in the GI tract include slower motility and less efficient absorption, including fats and bile acids. The gallbladder also becomes less responsive to meals, leading to reduced contraction and bile stasis. When bile sits stagnant, cholesterol can crystallize and form stones more readily. So, changes in absorption and gallbladder function with aging are linked to a higher risk of gallstones. Other aging changes, like cardiac hypertrophy, decreased GFR, or osteoporosis, affect the heart, kidneys, or bones and aren’t directly tied to absorption or gallstone risk.
