Admitted to hospital for low BUN, creatinine. Aren't they high during dehydration ?

I m a nursing student and have a 21 year old male pt in DKA. Hx of DM type I. Lab values seem a little off and i m looking for clarification. When he was admitted his BUN and creatinine were low but shouldn t they be high due to the dehydration/hyperosmolarity of hyperglycemic state? Unless BUN is low r/t polydypsia during DKA? Also while researching it says to monitor calcium and phosphate levels (they were also low upon admission to the ER), his TSH is high at 3.76. What s the correlation here? I can usually deduce the implications of these but I ve spent a considerable amount of time delving into possibilities...what am I missing?

Hi user
Thanks for posting query on healthcare magic
Primary problem of DKA is raised blood sugar, Dehydration (due to osmotic diuresis as result of raised sugar) and Ketone bodies
Low BUN and creatinine can not be explained however you may find low creatinine in very low muscle mass
You are right electrolytes like sodium, potassium, phosphorus should be monitored and corrected if low.
Raised TSH in rage 3.7 should be repeated after 3-4weeks
Hope you got the things clear
