Abstract
Bariatric surgeries have proven to be an effective treatment for morbid obesity to reduce the excess body weight of the
individuals. Besides weight loss and improvement in metabolic parameters, bariatric surgery procedures can also cause
some complications. One of the most common complications observed after bariatric surgery is vitamin deficiencies.
Vitamin deficiencies occur due to malabsorptive surgery in patients with absorption disorder and restrictive surgery
in patients with inadequate intake. These deficiencies may be accompanied by systematic and neurological findings.
Therefore, regular follow-up of patients after bariatric surgery is crucial. If any vitamin deficiency is detected in the
patient clinically or biochemically, it is recommended to eliminate this deficiency through supplementation.

Keywords: Obesity, bariatric surgery, vitamin deficiency, supplementation
