A 45-year-old woman is taken to an emergency department after an all day car trip, during which she did not have adequate access to fluids. She had required many bathroom stops, including three times when she had urinated behind a tree because no bathroom was immediately available. In the emergency department, she is found to have severe postural hypotension. Urine dipstick is negative for glucose. She continues to produce large volumes of urine, and urine osmolarity is low. On questioning, she has not noted any unusual drinking pattern, but her husband states that she "usually goes through four six-packs of diet soft drink" every day. The patient's condition improves with IV fluid replacement. Vasopressin injection increases her urine osmolarity by more than 50%. Which of the following is the most likely diagnosis?

A. Central diabetes insipidus
B. Compulsive water drinking
C. Diabetes mellitus type I
D. Diabetes mellitus type II
E. Nephrogenic diabetes insipidus

Did you see this? "...A 45-year-old woman is taken to an emergency department after an all day car trip, during which she did not have adequate access to fluids..." and this "...On questioning, she has not noted any unusual drinking pattern..."?
