I think part of the reason is that there is lots of money in treating acute symptoms with medication while there isn't much in having serious talks with patients to try to debug their lifestyle problems that might be causing their health problems and then educate them on what and why they should be doing it. I also think people naturally tend towards easy and fast solutions even if those solutions are known not to work. This self imposed blissful ignorance is what causes people to keep buying weight loss supplements or go on diets even though both are known not to work while we know that for 99% of people there is a simple solution -- reduce stress, learn to like to eat healthy and exercise daily.
