Diagnosis of diabetes
If a patient presents with frequency of passing urine, constant thirst, weight loss, tiredness, and found to have sugar in the urine, then the diagnosis of diabetes mellitus is very clear. What a doctor needs to do to confirm the diagnosis is to perform a blood sugar examination.
Many diabetics are discovered when they go for routine medical check up which consists of urine testing. Others are discovered when they consult a doctor for fungal infection of the vulva, recurrent boils, visual disturbances, unexplained weight loss, or even symptoms of pulmonary tuberculosis.
