Thanks for your query.
Well vitamin D toxicity can occur if you take it in excess of recommended doses as it is a fat soluble vitamin but main presentations of it will be dehydration
, fatigue , irritability , vomiting
etc.. Excessive sweating
of hands is less likely to be caused by this . Taking excessive alcohol may lead to redness of palms by virtue of deranged liver functions . Excess anxiety
can lead to sweating of hands . You need to see a physician to rule out these conditions by doing specialised test like Serum TSH , T3, T4 , Liver function tests, CBC, Urine R/M , RBS and other routine investigations for general well being status.
Thanks a lot for choosing HCM for your query.
