Symptoms and glucose test indicate diabetes

Steps:

• Identify classic symptoms: unexplained weight loss, polydipsia (thirst), and polyuria (frequent urination) suggest metabolic disorder.
• Note diagnostic test: high glucose in urine (glycosuria) points to impaired glucose regulation.
• Link symptoms to hyperglycemia: excess blood sugar spills into urine, causing osmotic diuresis and dehydration.
• Confirm match: these align directly with type 1 or type 2 diabetes diagnosis.

Why B is correct:

• Diabetes mellitus is defined by chronic hyperglycemia, leading to glycosuria, polyuria, polydipsia, and weight loss from caloric loss in urine.

Why the others are wrong:

• A: Cardiovascular disease involves heart/blood vessel issues like chest pain or hypertension, not glucose-related symptoms.
• C: Anemia results from low red blood cells, causing fatigue and pallor, without thirst or urinary glucose.
• D: Obesity features weight gain from fat accumulation, contradicting the unexplained weight loss.

Final answer: B
