You can self-test for diabetes through symptom observation, blood glucose monitoring with a home blood glucose meter, weight monitoring and other methods. The purpose of self-testing is to assess your risk of diabetes and conduct convenient self-checks, so that abnormalities can be detected early for further examination and treatment in hospital.
Symptom ObservationThe early stage of diabetes often presents with polydipsia, polyuria, polyphagia, and weight loss. If these symptoms occur frequently in a short period, be alert to the possibility of diabetes and seek further examination promptly.
Blood Glucose MonitoringUsing a home blood glucose meter is a common self-test method.
Fasting blood glucose reflects the basic blood glucose level, preferably measured before eating in the morning. The normal range is generally 3.9–6.1 mmol/L.
2-hour postprandial blood glucose evaluates blood glucose fluctuation after meals, timed from the first bite of food. The normal value should be below 7.8 mmol/L.If readings repeatedly exceed the normal range, go to the hospital for diagnosis to adjust lifestyle or receive treatment.
Weight Monitoring
Weight changes are obvious in diabetic patients. Some patients experience weight loss in the early stage, because the body cannot metabolize glucose normally and breaks down fat for energy instead. Regular weight measurement and tracking trends can help assess disease progression.
