Gastric Bypass - Bariatric Surgery Nutritional Assessment

Bariatric surgeries are increasingly used to treat overweight and obese patients who have clinically relevant signs and symptoms. Approximately 228,000 bariatric surgeries were performed in the United States in 2017.  These procedures can be successful in reversing many adverse syndromes associated with obesity (including type II diabetes, hypertension, joint pain, obstructive sleep apnea, hyperlipidemia, and coronary artery disease ), but there are risks and complications to consider, such as the exacerbation of preexisting nutritional deficiencies and the development of new ones. Some deficiencies present soon after surgery, but the late presentation of nutritional deficiencies is increasingly recognized to contribute to poor outcomes or devastating complications. Bariatric surgeries that use a restrictive technique may lead to nutritional deficiencies due to low intake, whereas restrictive surgeries combined with malabsorptive techniques, such as Roux-en-Y gastric bypass (RYGB), may lead to nutritional deficiencies due to either low intake or malabsorption.  Therefore, long-term monitoring for nutritional deficiencies is indicated following gastric bypass surgeries.
