AB Hypothyroidism  is  a  clinical  syndrome  caused  by  insufficient  thyroid  hormone  production,  which  slows  cell  metabolism.  Hypothyroidism  is  common  in  areas  where  iodine  deficiency  is  common,  particularly  inland  areas  where  there  is  no  access  to  marine  foods.  In  iodine-sufficient  areas,  chronic  autoimmune  destruction  of  thyroid  gland  (e.g.,  Hashimoto's  thyroiditis)  and  iatrogenic  causes  from  treatment  of  Graves'  disease  are  the  leading  causes  of  hypothyroidism  (after  thyroidectomy  or  radioactive  iodine  ablation).  The  prevalence  of  hypothyroidism  increases  with  age,  and  the  disorder  is  nearly  10  times  more  common  in  females  than  in  males.1  Subclinical  hypothyroidism  is  more  prevalent  than  overt  hypothyroidism  in  all  age  groups  and  can  be  seen  in  4%  to  15%  of  women,  especially  the  elderly.2,3
