A diabetic patient who has a fruity odor to their breath may describe a patient:

in cardiac shock
with Type 2 diabetes
with ketoacidosis
with hypoglycemia

with ketoacidosis

Rationale: Excess glucose levels in the blood can escalate to formation of keytone bodies causing ketoacidosis. Very high sugar levels will spill over into the urine. A patient who exhibits signs of extreme thirst, urinates frequently and has sweet smelling breath could be life threatening and needs to be medically addressed with insulin and fluids.
