Bariatric Surgery and Malabsorption

The risk for malabsorption (nutrient or medication) after bariatric surgery is dependent upon the type of surgical procedure performed; the patient's level of adherence to medications, supplements, and diet; and the types of dosage forms administered following surgery. Pre- and postoperative nutrient deficiencies have been observed for several decades in the bariatric population.[15] In addition, postoperative alterations in the pharmacokinetics of medications have been described and can be attributed to a variety of mechanisms.[14,16]
