Answer: C. The follow up care of a Roux-en-Y gastric bypass patient is critical and involves a life-long commitment for the patient and the primary care provider. In the immediate post-operative period, the patient should be followed by their bariatric surgery team. The primary care provider should become involved soon after the procedure. The patient should be seen every three months for the first year by either the bariatric surgery team or their primary care provider. This frequent follow-up schedule allows for early diagnosis of common post Roux-en-Y gastric bypass complications, such as hernias, iron deficiency anemia, and anastomotic concerns. After the first year, the patient should continue to see their bariatric surgery team or primary care provider at least once a year to review their weight, undergo laboratory tests to rule out concerns for vitamin deficiency, and identify any psychological concerns that may affect the patient’s success with long-term weight maintenance.
