<s>[INST] HI! My grandmother's age is 75. She just underwent heart bypass surgery and after a month from her surgery she is now experiencing shaky hands for a few days.We did visit her heart doctor and they said all is fine.But her report suggests that she is lacking proteins.Could deficit protein contents in her body cause shaky hands? [/INST] Not reall,  though lack or proteins and hemoglobin at her age a can cause generalised weakness which may result in shaking,  also in during bypass small twigs of peripheral nerves are cut particularly if the graft are then grow that side which may result in paraesthesia,  also if it's of slow onset rule out parkinsonism or other movement disorder.  However treated protein Def by hood quality protein diet will be the best way to rule out.  However no supplement ot iv recommended till albumin is less than 3.  Regards Dr priyank mody </s>
