Serious clinical manifestations of vitamin deficiency after a "sleeve" gastrectomy: role of psychogenic anorexia]

Morbid obesity is an emerging condition in the general population. Bariatric surgery, which has demonstrated its effectiveness for weight loss, mortality and morbidity related to obesity, is required in some patients. However, it may be associated with various adverse effects, including vitamin deficiencies.We report a 33-year old man who presented central and peripheral neurological deficits and cardiac manifestations related to multiple vitamin deficiencies, following "sleeve" gastrectomy. The vitamin deficiencies were related to insufficient ingesta secondary to psychogenic anorexia. The patient improved with vitamins, antidepressant drugs and atypical neuroleptics.Post-operative complications of "sleeve" gastrectomy include vitamin deficiencies that can develop in the context of psychogenic anorexia and ingesta reduction, in the absence of any digestive malabsorption.
