Components Of Preventative Medicine: Why Are They Important?

Components Of Preventative Medicine

Also known as prophylactic medicine, preventative medicine is a branch of medicine that deals with the prevention of disease. The main aim of preventative medicine is protecting the health of individuals and populations. It is a science that uses various means to prevent the occurrence of disease.

Preventative medicine is a relatively new field. It has only been during the last century that the importance of preventative medicine has been widely recognized. You can learn more about this and other aspects of healthcare by pursuing an accelerated nursing program. 

Even if you’re in a different career field, the University of Indianapolis online ABSN program can help you get started in the dynamic field of nursing. The program is designed for students who have earned a non-nursing bachelor’s degree and are interested in becoming registered nurses. Upon successful completion of the program, students will be eligible to take the NCLEX-RN licensure examination.

The goal of preventative medicine is to prevent or delay the onset of disease and improve the health of those at risk of developing diseases. There are many key aspects of preventative medicine, including: 

  • Early detection: Early detection of disease is essential to the successful treatment of disease
  • Risk factor reduction: This reduces the likelihood of developing the disease
  • Health promotion: Health promotion is the process of improving the health of individuals and populations. It includes measures to prevent the development of disease, promote good health, and reduce the impact of the disease

What Does Preventative Medicine Entail?

Disease prevention is the primary aim of preventative medicine. It is the process of protecting against the development of disease. Preventative medicine includes a wide range of activities.

Here are some of the most common components of preventive medicine.

Active lifestyle

Engaging in an active lifestyle through regular exercise is essential for preventing the development of cardiovascular disease. Likewise, exercise can help to reduce the risk of developing diabetes by combating insulin resistance and improving blood sugar control.


Proper nutrition is a key element of preventative healthcare. Dietary guidelines are aimed at providing healthy dietary choices and avoiding risk factors that lead to chronic diseases. For example, dietary guidelines implore individuals to limit their consumption of trans-fatty acids and saturated fat in order to prevent cardiovascular disease and improve healthy lipids (fats) in the body., 

Regular screenings

Regular screenings for individuals with risk factors can detect diseases in the early stages when treatment is likely to have a positive outcome. This can be done by undergoing routine exams. For example, individuals should undergo periodic screenings for breast cancer, colon cancer and heart disease based on their age and other risk factors.


Vaccines are effective in helping to protect the body against certain diseases. This is particularly true for childhood diseases such as measles and chickenpox. Adults can benefit from vaccines for some diseases as well. For example, annual flu vaccines are recommended for many adults. 

Family history screening

Family history is one of the most important risk factors for developing diseases. For example, a family history of heart disease increases an individual’s risk of developing heart disease. Screening a family’s medical history helps identify those at risk, and preventative measures can be taken to minimize their chances of developing them.

Stress management

Stress management is essential for improving quality of life and preventing illnesses. Individuals who experience chronic stress are more likely to develop psychological disorders. Therefore, mastering stress management can help prevent these diseases from developing.

The effects of stress have been implicated in several diseases. Therefore, stress management is an important part of disease prevention; it encompasses exercise and meditation as well as other techniques that allow individuals to combat stress.

Good hygiene

Maintaining good hygiene is essential for top health. You should make sure that you wash your hands frequently and cover all exposed areas of the body with sunscreen before going outside. In addition, you can use some common home remedies for skin conditions such as acne or eczema to help prevent the development of infection.

Avoiding environmental pollutants

Environmental pollution can have negative effects on the human body and increase the risk of developing certain diseases, such as cancer. Avoiding exposure to environmental pollutants is essential to prevent the development of cancer, and this is particularly true for individuals in high-risk groups such as smokers and those who live near industrial sites. In fact, smoking is linked to numerous health problems, including heart disease, lung cancer and stroke.

Avoiding additives

Some food additives, preservatives, and dyes can have negative effects on the human body. Therefore, it is important to avoid these to improve health and prevent diseases. To protect your health, you should avoid additives such as artificial sweeteners and coloring agents in foods, beverages, drugs and cosmetics.

Specialties in preventative medicine

The role of preventative medicine within the healthcare field is continuously evolving. As new health risks emerge and technology improves, more doctors are becoming involved in the preventative medicine community. Here is a look at a few specialties in medicine that are dedicated to preventative care.
