See a doctor, get a prescription, the current state of medical practice worldwide is based on 'treatment of acute and chronic medical conditions' and not on 'prevention'.
Prevention requires comprehensive testing as a starting point to assess the current state of one's health, even when one is not showing any outward symptoms of illness.
The test results will demonstrate for both those who already have symptoms of illness, and those who do not, what behavioural and/or natural dietary modification should be made to address their health risks.
To assess the impact of behavioural and dietary changes, tests must be repeated periodically.
Comprehensive testing may seem complex to some, especially those who have accepted the historic and ongoing medical establishment's approach to medical care. It may cost some money out of their pocket, a bitter pill to swallow for those accustomed to society (taxpayers/government) paying for their medical care, but as the saying goes 'an ounce of prevention is worth a pound of cure'.
