Hi and thank you so much for this query.
I am so sorry to hear about what your friend is experiencing. It is so atypical for dehydration
to cause fevers in the 103-105F and shaking. Rarely would this happen if ever. But it being relieved by drinking makes the whole scenario even more confusing. Because of the excessive thirst, I will suggest that she should be tested and cleared of diabetes
. Also, is she urinating much? We would only settle with dehydration as a possible explanation if all other investigations show no other possible cause.
I hope you find this helpful. Thank you for using our services and please feel free to ask for more information if need be. I wish you the best of health.
Dr. Ivo, MD.
