How often should you actually get a health check if you have no symptoms?

For a healthy adult without risk factors, targeted checks every one to three years are reasonable rather than an annual full-body package. What is genuinely worth tracking: blood pressure, which can be checked at any pharmacy visit; blood glucose or HbA1c; a lipid profile; and waist circumference. Frequency increases with age, family history, obesity, or an existing condition. The comprehensive panels sold commercially often include tests with poor screening value that generate incidental findings, further testing and anxiety without improving outcomes. Value comes from acting on results, so plan the follow-up when you plan the test.
