However, complications may occur, especially when malabsorptive surgeries like a biliopancreatic diversion is performed. We present the case of a female patient whose obesity was treated with this technique, and in the 9th year of follow-up developed an extensive dermatitis secondary to zinc deficiency and malnutrition, precipitated by therapeutic non-compliance. A close surveillance of early symptoms and signs of nutritional deficiencies as well as chronic supplementation of vitamins and trace elements is required; this case illustrates the relevance of periodical, lifelong visits to a medical physician with special training and experience in the management of post bariatric surgery patients in order to prevent, diagnosis and early treat related complications.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/bariatric surgery complicationsbiliopancreatic diversiondermatitissevere malnutritionzinc deficiencyAdultAvitaminosisBariatric SurgeryDermatitisFemaleHumansMalnutritionObesity, MorbidZincresearch article34054719open access10.3389/fendo.2021.623543PMC8152933https://www.frontiersin.org/articles/10.3389/fendo.2021.623543/pdfhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC8152933/pdf
