Diabetes can lead to kidney damage, known as diabetic nephropathy. Signs that your kidneys may be affected include swelling in your feet or ankles, changes in urination frequency, and blood in your urine. You may also experience fatigue or have high blood pressure. Regular check-ups with your GP are essential, as kidney damage can often progress without symptoms. Early detection through blood and urine tests can help manage and slow down any damage, protecting your overall health. If you're noticing these signs, it's important to discuss them with your healthcare provider.
