Final answer:
Glycosuria is the symptom not associated with diabetes insipidus; it is a symptom of diabetes mellitus. Diabetes insipidus presents with Nocturia, Polyuria, and Polydipsia.
Step-by-step explanation:
The symptom of diabetes insipidus that is not listed among the symptoms of this condition is c. Glycosuria. Diabetes insipidus is characterized by symptoms such as Nocturia (excessive urination at night), Polyuria (frequent urination), and Polydipsia (increased thirst and fluid intake). Glycosuria, which is the presence of glucose in the urine, is not a symptom of diabetes insipidus; instead, it is one of the symptoms of diabetes mellitus. While both diabetes mellitus and diabetes insipidus cause increased urine volume, the urine in diabetes mellitus contains high levels of glucose, whereas in diabetes insipidus, the urine is diluted and mostly free of glucose.
