Diabetic patients have a heavier urine smell for the following reasons: First, because the patient’s blood sugar is higher, the urine sugar content increases, and usually drink less water, the smell will be a little heavier. Second, diabetic patients who eat more protein and other foods, such as meat, eggs, milk, etc., will also have the problem of heavy urine odor. Thirdly, if a diabetic patient has a combined urinary tract infection, the white blood cell content in the urine will increase significantly and the smell of urine will be heavier. If a diabetic patient has a heavy urine odor or a big change from the previous one, he should go to the hospital for a urinalysis in time.
