For reasons that are beyond me, the accepted healthcare 'wisdom' is that regular testing increases anxiety particularly if there is a particularly high reading or two.
This could be translated into 'ignorance is bliss'. It isn't. Ignorance is ignorance.
When on the way down a series of readings provides continual encouragement, as well as information on what an individual can eat or might best avoid.
After that much of the time an individual high reading can be traced to something, maybe a food item or a moment of stress. A prolonged slightly elevated level might be result of some kind of infection. Discovering a persistent significant rise though can set off alarm bells before other symptoms.
In summary, it empowers you.
