Sometimes it does get tricky to find the root causeThat's the problem though. People get lazy, doctors offices take too many appointments, throw some antibiotics and bring in the next patient. We as a society need to dissuade this behavior and reward applying scientific methods, lab tests, tissue samples, etc... even if it is perceived to be invasive or expensive. The medical system has become too focused on profits over patient longevity. Instead they are incentivized by high churn patient turn-around, most often just treating symptoms or making problems worse.
I believe there needs to be a new model created to displace and disrupt the current model. There have been some attempts using functional medicine and more of those clinics are being created but that is not fast enough to catch up to the national security conundrum of mass mortality issues resulting from lazy and profit driven procedures.
