While the focus of the medical field is to develop and implement effective treatments to address existing medical conditions, the focus for patients ought to remain on prevention. Though the use of preventive strategies for ensuring continued health, there is a greater likelihood that major medical issues are avoided and that a better quality of life can be enjoyed.
Of course, most people want to lead healthy lives free from difficult medical issues but are nonetheless unable to adopt the preventive methods needed to do so. This is the result of multiple factors of varying complexity, but it is entirely possible for positive changes to be made to ensure a greater level of prevention across the whole of the population.
Prevention should always begin with a focus on habits relating to diet and exercise. When discussing these particular issues, it is best to focus on incrementally improving the existing habits with the eventual goal of implementing an appropriately healthy diet along with an ideal fitness regimen.
Trying to make wholesale changes most often leads to frustration and results in a return to the previous poor habits, thereby making prevention all the more difficult. Any positive gain, however small, is beneficial and helps reduce the likelihood of requiring medical care, but the gains should also be oriented so that they ultimately lead to sweeping and positive changes.
