What Is Medicine?

Medicine is a fascinating and constantly evolving field of science that deals with the diagnosis, treatment, and prevention of disease. You may be considering a career in medicine, or simply have an interest in learning more about how the human body works and how it can be cared for.

The Medical Curriculum

Becoming a doctor is no small feat. It requires a significant commitment of time, energy, and resources, as well as a strong foundation in science and math. The medical curriculum typically begins with a pre-med program, which includes coursework in biology, chemistry, physics, and math.

After completing the pre-med program and taking the Medical College Admission Test (MCAT), aspiring doctors can apply to medical school. Medical school typically lasts four years and involves a combination of classroom learning and hands-on clinical experience. During this time, students learn about a wide range of topics, including anatomy, physiology, pharmacology, pathology, and medical ethics.

Upon completing medical school, aspiring doctors must complete a residency program, which is a supervised training program that provides hands-on experience in a specific medical specialty. Residency programs can last anywhere from three to seven years, depending on the specialty.

Common Diseases

As a medical professional, you will encounter a wide range of diseases and conditions. Some of the most common diseases include:

  • Cardiovascular disease: This umbrella term refers to a range of conditions that affect the heart and blood vessels, including coronary artery disease, heart failure, and hypertension (high blood pressure).
  • Cancer: Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. There are many different types of cancer, including breast cancer, lung cancer, and colon cancer.
  • Diabetes: Diabetes is a chronic condition in which the body is unable to properly regulate blood sugar levels. There are two main types of diabetes: type 1 and type 2.
  • Mental health disorders: Mental health disorders, such as depression, anxiety, and bipolar disorder, are conditions that affect a person's mood, thoughts, and behavior.
  • Infectious diseases: Infectious diseases are caused by bacteria, viruses, or other microorganisms and can be transmitted from person to person or through contaminated food or water. Examples include influenza, HIV/AIDS, and Ebola.

Medical Specialties

After completing medical school and a residency program, doctors can choose to specialize in a particular area of medicine. Some of the most common medical specialties include:

  • Pediatrics: Pediatrics is the branch of medicine that deals with the medical care of children, from newborns to young adults. Pediatricians focus on preventing, diagnosing, and treating a wide range of health conditions in children.
  • Surgery: Surgeons are doctors who specialize in performing operations to treat a variety of conditions, including cancer, heart disease, and injuries.
  • Internal medicine: Internal medicine is a specialty that focuses on the diagnosis and treatment of adult diseases. Internal medicine doctors, also known as internists, may focus on a particular organ system or a specific patient population, such as seniors or women.
  • Psychiatry: Psychiatry is the medical specialty that focuses on the diagnosis, treatment, and prevention of mental health disorders. Psychiatrists are trained to use a variety of therapies, including medication and talk therapy, to treat their patients.
  • Emergency medicine: Emergency medicine is a specialty that deals with the immediate care of patients with acute illnesses or injuries. Emergency medicine doctors work in hospitals, clinics and other healthcare settings, providing care to patients in need of immediate attention.
  • Obstetrics and gynecology: Obstetrics and gynecology is the medical specialty that focuses on the care of women, including pregnancy, childbirth, and conditions related to the reproductive system. Obstetricians and gynecologists (OB/GYNs) provide care to women throughout their lives, from adolescence to menopause.
  • Anesthesiology: Anesthesiology is the medical specialty that focuses on the administration of anesthesia, a drug that is used to block pain during surgery or other medical procedures. Anesthesiologists work closely with surgeons and other healthcare professionals to ensure that patients are comfortable and pain-free during procedures.

In addition to these specialties, there are many other areas of medicine that doctors can choose to focus on, including dermatology, neurology, and ophthalmology, to name just a few. No matter what specialty a doctor chooses, the goal is always the same: to improve the health and well-being of their patients.
