KW - Laparoscopic sleeve gastrectomy, selenium deficiency, zinc deficiency, dilated cardiomyopathy
AB - Background: Sleeve gastrectomy for weight loss has increased significantly nowadays. Various complications may develop after this surgery that requires long-term follow-up of these patients. Nutrition is the most important aspect of the follow-up. The deficiency of trace elements, fat-soluble and water-soluble vitamins following bariatric surgeries have been well-described complications. Although nutritional supplementations are often initiated after bariatric surgery, the clinical outcomes related to the deficiency of trace elements have not been well known yet. 
Case Presentation: A 27-year-old woman who underwent a laparoscopic sleeve gastrectomy for surgical treatment of obesity 9 months ago presented to the emergency department with a signs of heart failure. Transthoracic echocardiography revealed dilated, poorly functioning left ventricle with reduced ejection fraction (28.9%) consistent with dilated cardiomyopathy. We assumed nutritional deficiencies secondary to sleeve gastrectomy as a cause of dilated cardiomyopathy, as the patient had inappropriate nutritional supplements after surgery. Laboratory tests revealed selenium and zinc deficiency that supported our hypothesis. Our patient completely recovered with adequate supplementation of selenium, zinc and thiamine. 
Conclusion: We highlighted that the early diagnosis of dilated cardiomyopathy due to selenium deficiency following bariatric surgery is of great importance since selenium deficiency is a cause of reversible cardiomyopathy.
