Neurologic complications due to vitamin deficiencies after bariatric surgery
Main Article Content
Bariatric surgery is the most effective method of treating morbid obesity, but after its performance the patient may develop vitamin deficiency. Against the background of insufficient food intake and absorption disorders after the surgery, the deficiency of vitamins B1, B6, B12 and vitamin E is observed first of all, which leads to complications in the form of central and peripheral nervous system dysfunctions. The most pronounced changes of the nervous system are observed with vitamin B1 deficiency in the form of polyneuropathy and severe Wernicke's encephalopathy. Vitamin B12 deficiency is clinically manifested by a picture of funicular myelosis and polyneuropathy. Insufficient intake of vitamin B6 and vitamin E leads to polyneuropathy. Only the early start of treatment guarantees a favorable outcome of the neurological deficit.
