Quizplus · Accepted Answer

The reduction in surface area of the stomach after gastric resection can lead to malabsorption of B12. Therefore, the registered dietitian may prescribe B12 supplementation. Choices A, B, and C are not necessarily indicated based on the information provided in the case study. Gastric resection leads to a reduction in the surface area of the stomach, which impacts the absorption of nutrients. Vitamin B12 is primarily absorbed in the distal ileum and requires intrinsic factor, which is secreted by the parietal cells in the stomach. As a result, individuals who have undergone gastric resection may develop vitamin B12 deficiency due to a lack of intrinsic factor. Supplementation with vitamin B12 is typically prescribed in these cases. Options A, B, and C are not specifically indicated based on the patient's medical history and symptoms.
