A variety of situations place the bariatric surgery patient at increased risk for thiamine deficiency after surgery. These include the following: 1. Nausea and vomiting are common occurrences after bariatric surgery. This side effect may be related to a variety of factors including patient eating behaviors or surgery-related complications, such as stenosis and/or bowel obstruction.[1] Bariatric surgery patients are at an increased risk of developing thiamine deficiency, particularly after an episode of intractable vomiting.[2] 2. Bariatric surgery results in a drastic restriction in energy intake, which requires additional vitamin and mineral supplementation. Nonadherence to a multivitamin regimen puts patients at risk for a variety of deficiencies, including that of thiamine. 3. Thiamine deficiency is also observed in patients with periods of high carbohydrate intake, such as nasogastric feeding, total parenteral nutrition, or intravenous hyperalimentation.
