Symptoms and glucose test indicate diabetes

Steps:

• Identify classic symptoms: unexplained weight loss, polydipsia (thirst), and polyuria (frequent urination) suggest a metabolic disorder affecting glucose regulation.
• Note the diagnostic test: high glucose in urine (glycosuria) confirms impaired insulin function or production.
• Match to known conditions: these align directly with hyperglycemia in diabetes mellitus.
• Eliminate mismatches: other options lack these specific signs or test results.

Why B is correct:

• Diabetes mellitus is defined by chronic hyperglycemia, leading to osmotic diuresis (causing thirst and urination) and glycosuria when blood glucose exceeds renal threshold.

Why the others are wrong:

• A. Cardiovascular disease involves heart or vessel issues, not glucose-related symptoms or urine tests.
• C. Anaemia causes fatigue and pallor from low red blood cells, without thirst, urination, or glycosuria.
• D. Obesity features weight gain, not loss, and no direct link to high urine glucose.

Final answer: B
