The Different Fields of Medicine

The different fields of medicine offer an exceptionally broad look at the many ways that the human body can be analyzed, diagnosed, and treated in order to prevent and cure disease on our way to a better understanding of our basic nature.  As technological progress and increased research allow for more in-depth exploration of medicine, the number of specializations continues to grow.  Let’s take a look at some of medicine’s different fields and how they fit into the overall health care picture.

Anatomy is one of the most basic and intricate medical fields.  It centers around an understanding of the physical components of the human body.  This includes things which we can easily see with the naked eye, such as our skin and our external organs (eyes), as well as internal organs like the liver, the lungs, and the brain.  Anatomy also has a microscopic component involving the tiniest structures of the body, all of which play a role in the miracle of life.

Epidemiology is the study of disease and disease vectors.  In simpler terms, it looks at how illnesses can spread through a population and how medical science can best be used to treat and prevent disease.  The work of an epidemiologist involves searching for patterns and common clues between seemingly unrelated activities and symptoms, as well as developing an excellent understanding of the mechanisms by which diseases can be communicated and controlled.

Neuroscience is an interdisciplinary science that involves both biology and medicine.  Doctors who specialize in neuroscience are fascinated by the role of the nervous system – which includes the brain – and how it controls and transmits the signals which allow human beings to process sensory input, achieve motor control, and form thought.  Neuroscience is one of the most puzzling fields in all of medicine, due to the many mysteries presented by the brain and the difficulty of solving them.

Surgery is a unique specialty in medicine that encompasses the doctors who decide when an operation is required to solve a health issue.  These doctors possess excellent motor skills and are capable of making rapid decisions based on the changing health of the patient on the operating table in front of them.  Surgeons themselves often specialize in different fields, such as cardiovascular surgery, plastic surgery, or neurosurgery.

Cardiology is the domain of doctors who help to heal issues stemming from a patient’s cardiovascular system.  This can include problems such as heart disease or heart failure, artery restrictions, or any other number of related areas.  Since heart disease is one of the most prominent killers in the United States, cardiologists are in high demand.  Many of the treatments prescribed by cardiologists can be considered lifestyle treatments, in that they demand that patients change their daily habits – usually their diets – in order to improve the health of their circulatory system and heart.

The final field of medicine that we will look at in this article, obstetrics and gynecology, deals with reproductive health as well as fertility and birthing.  Over the past several years, due to the skyrocketing costs of insurance, very few medical students have become involved in obstetrics, resulting in a demand for this specialty that far exceeds supply.

The medical fields listed above just barely begin to scratch the surface when it comes to the number of specialties and fields to be found under the banner of medicine.  Almost every aspect of the human body has been subject to the attention of a group of doctors who are fascinated with expanding and promoting the knowledge of their chosen field.  These passionate individuals together contribute to the greater picture of human health that benefits us all.
