Diabetic urine can vary in appearance depending on the severity of the diabetes and other factors. Generally, however, it may appear foamy, frothy, or bubbly due to the presence of glucose (sugar) in the urine. The color may also be darker than usual, due to the presence of proteins. In some cases, the urine may be cloudy and have an unusually sweet smell. In more severe cases, the urine may contain ketones, which can give it a fruity or acetone-like smell.
Diabetic urine may also contain more sediment than usual, which can appear as a white, milky, or cloudy substance. This sediment is typically composed of fat, protein, and red blood cells, and it can be an indication of kidney damage. Additionally, red or brown urine can be a sign of blood present in the urine, which can be the result of diabetic nephropathy (kidney disease) or urinary tract infections.
If you suspect that you or someone you know may have diabetes, you should seek medical attention immediately. A doctor can order a urine test to determine if glucose is present in the urine, which can be a sign of diabetes.
