The most common symptom my patients have of the onset of diabetes is: none!Most of my Frontline Diabetes patients are adults who I see on a regular basis, many of whom receive blood testing periodically. Patients who are at risk for diabetes - who are overweight or have a family history of diabetes - are often diagnosed on routine blood tests done for other reasons. Usually these patients exhibit no specific symptoms.
Historically, excess thirst, frequent urination, weight loss, and increased hunger have been cited as classic diagnostic signs. Sweet tasting urine is another, but modern day doctors rarely use this diagnostic test. (Most doctors don't know how regular urine tastes, anyway.) The latin words, diabetes mellitus, mean "run-through honey."
However, by the time a patient's blood sugar is high enough to cause these symptoms, diabetes is usually quite advanced.What causes thirst and frequent urination in a diabetic? The kidney normally is capable of absorbing all the glucose that flows through it. However, above a certain threshold, usually around a blood sugar of 200 to 300 mg/dL, the kidney can no longer absorb all the blood glucose, resulting in the sugar "spilling" into the urine. Glucose in the urine acts as a diuretic, causing increased volume of urination and therefore increased urinary frequency.
