A 33-year-old female with obesity has chronic fatigue and anemia 5 years after a Roux-en-Y gastric bypass procedure for weight reduction. What is the most likely deficiency?
Select Your Answer:
2. Vitamin B12
Nutritional deficiencies after gastric bypass occur in 30% of patients.
Malabsorption of the fat-soluble vitamins A, D, E, and K are quite common. Iron deficiency anemia often occurs after gastric bypass procedures.
Lifelong oral supplementation of iron, vitamin B1, folate, and calcium are recommended to avoid specific nutrient deficiency.
Other late complications include food intolerance, failure to lose weight, reoperation, esophageal dilatation, and a mortality of close to 1% to 3%.
