Kidney disease caused by diabetes is called diabetic nephropathy. In the early stages, patients may not have any noticeable discomfort, while some may experience soreness and discomfort in the lower back. However, as diabetic nephropathy progresses, with further increase in urinary protein, patients will see more foam in their urine and may also experience swelling of the eyelids and lower limbs. Once diabetic nephropathy progresses to the stage of uremia, patients will exhibit symptoms such as nausea, vomiting, general weakness, loss of appetite, increased frequency of urination at night, significant increase in blood pressure, and reduced urine output. Additionally, symptoms of anemia may also occur. Therefore, diabetic nephropathy must be given adequate attention to prevent the onset of uremia.
