Multiple micronutrient deficiencies as a long-term complication of bariatric surgery

Devika Dixit et al. BMJ Case Rep. .

Abstract

Micronutrient deficiencies may develop as a long-term complication of bariatric surgery due to alteration of gut anatomy and disruption of normal gut absorption. Inadequate repletion of essential vitamin and mineral deficiencies can lead to multisystem dysfunction. We present a case of a woman in her 50s, with a history of Roux-en-Y gastric bypass over 10 years ago, who presented with generalised weakness and a diffuse desquamating rash. A punch biopsy performed was compatible with nutritional deficiency. Labs revealed low levels of micronutrients A, B1, B6, C, E, zinc and copper. The patient received intravenous micronutrients and an oral regimen, which improved her symptoms. Unfortunately, the patient died from cardiac arrest secondary to pulmonary oedema. This report highlights the importance of high suspicion of micronutrient deficiency in patients with a history of bariatric surgery and maintaining lifelong nutritional follow-up.
