The symptoms presented by the patient are classic signs of diabetes mellitus, specifically type 1 diabetes. The constant thirst and frequent urination are due to hyperglycemia, which causes the kidneys to excrete excess glucose into the urine, pulling water along with it. This leads to dehydration and an increased need to drink fluids. The unintentional weight loss is also a common symptom of uncontrolled diabetes, as the body begins to break down fat and muscle tissue for energy in the absence of adequate glucose uptake. Renal cancer, bladder cancer, and interstitial cystitis are unlikely causes of these symptoms, and would usually present with other signs and symptoms as well.
