Disease Prevention – the Basic Need of a Healthy World
We all have learned in our school years while studying science that prevention is better than cure. There is indeed an important component of healthcare called prophylaxis meaning preventive healthcare and it comprises of measures to be taken for preventing a disease rather than treating it. Just as health includes various physical and mental stages, diseases too are affected by disease agents, genetic predisposition, environmental factors and lifestyle choices. Disease prevention depends on defensive actions that can be classified as primary, secondary and tertiary prevention.
Disease prevention is a vast subject and includes innumerable factors.
Regular Health Checkup
Even if you feel overall healthy you should get a regular health checkup done to identify in case if there are any likely symptoms of diseases. Such a checkup includes disease screening, checking risk factors, know about healthy lifestyle and get vaccines regularly. Some general disease screenings are done for hypertension, hyperglycemia (a risk factor for diabetes), hypercholesterolemia (high cholesterol), colon cancer, HIV, depression and osteoporosis. Genetic tests can also be done to screen genetic disorders or tendency of particular diseases like ovarian or breast cancer. However, all these measures cannot be afforded by every individual and this is a topic of concern.
Primary prevention includes methods for avoiding an episode of disease either by eradicating the disease agents or increasing immunity to disease. These include immunization, taking a healthy diet, regular exercises and avoiding smoking.
Secondary disease prevention includes methods to detect and deal with an already occurred disease before symptoms start showing, e.g. treating hypertension (a threat leading to several cardiovascular diseases).
Tertiary prevention includes methods to minimize the negative effects of symptomatic diseases like disability or even death, through treatment and rehabilitation, e.g. surgeries which are done to stop the spread of disease.
