Diabetes can affect vision, kidneys, nerves and the cardiovascular system. Regular follow-up helps detect complications. This overview does not interpret glucose results or recommend changing medicine without professional guidance. Ask about eye checks, kidney blood or urine tests, foot and nerve assessment, and heart-health risks. These checks look for different problems; a home glucose result does not replace them. Bring glucose records, a medicine list and any new wound or vision change to appointments. Agree the timing of checks with the treating team instead of following an invented universal interval.
