AB Patients  can  develop  neuropathies  due  to  inadequate  nutrition  and  subsequent  vitamin  deficiency  (Table  18-1).  Nutritional  deficiency-related  polyneuropathies  are  currently  uncommon,  especially  in  developed  countries.  However,  these  neuropathies  do  occur  and  are  important  because  they  are  potentially  treatable.  Malnutrition  may  occur  in  chronic  alcoholics  and  in  patients  with  chronic  illness,  unusual  diets,  and  obesity  surgery.  Some  vitamin  deficiencies  (e.g.,  vitamins  B12  and  E)  often  occur  because  of  impaired  gastrointestinal  absorption  rather  than  poor  dietary  intake.  In  other  cases,  neuropathy  may  develop  secondary  to  the  effects  of  medications  (e.g.,  isoniazid  causing  vitamin  B6  deficiency).  The  clinical  and  laboratory  features  of  most  nutritional  polyneuropathies  are  similar  to  those  of  the  more  common  polyneuropathies.  Timely  and  accurate  diagnosis  is  important  because  patients  can  improve  with  replacement  therapy.
