Surgery>>>>>The Surgical Management of Obesity
Question 9#

Adolescent patients with morbid obesity are increasingly being referred for consideration of bariatric procedures due to failure of medical management and the risks associated with a lifetime of obesity. What nutritional deficiencies require life-long treatment after RYGB, the most common procedure performed in this age group?

A. Pernicious anemia due to vitamin B₁₂ deficiency
B. Iron deficiency anemia
C. Deficiencies of vitamins A, E, D, and K
D. All of the above

Correct Answer is D

Comment:

Loss of intrinsic factor produced in the gastric fundus, impaired iron absorption, and a deficiency of the fat -soluble vitamins present life-long risks after RYGB and other malabsorptive bariatric procedures. Vitamin replacement and nutritional monitoring are therefore mandatory in bariatric patients.
