The internist must then receive training to identify and treat a wide range of illnesses, as well as many patients with chronic and complex problems, given the ageing population.

The internist, a specialist in internal medicine, typically works in hospitals where they can oversee patients’ care in outpatient clinics or provide acute disease care. In several nations, a respectable portion of internists have a hospital-affiliated office-based practice along with reference to other hospitals.

Note:However, a “family doctor” who handles a far wider variety of issues, such as obstetrics and surgery, and who treats both adults and children, is not an internist.

General Internal Medicine

After completing their basic internal medicine training, many internists begin their careers in practice. These medical professionals are sometimes known as “general internists,” who practice “general internal medicine.”

They are not constrained to one type of organ system or medical condition. Regardless of how common or uncommon, straightforward, or difficult a patient’s situation may be, general internists are prepared to handle it. They can deal with severe chronic illnesses, situations in which multiple illnesses may manifest simultaneously, and complex diagnostic challenges because they have received specialized training in these areas.

Various environments are possible for general internists to work in. Their education uniquely enables them to provide primary care, follow patients throughout adulthood, and build enduring & lasting connections with their patients. Although internists may serve as primary care doctors, they are not “family physicians,” or “general practitioners” whose training may include surgery, pediatrics, and obstetrics in addition to an emphasis on treating adults.

Hospitalists are general internists who specialize in providing care for patients when they are hospitalized; in the US, general internists make up the majority of hospitalists. Some general internists are capable of combining various types of care for their patients, offering both outpatient and inpatient care. While other general internists might work in distinctive places like long-term care institutions and rehabilitation centers, among other medical settings.

Internal Medicine Subspecialties

To “subspecialize” in a more narrowly focused area of internal medicine, some internists decide to pursue extra education. The standard three-year internal medicine residency is followed by an extra one to three years of subspecialty training, also known as a “fellowship.” Doctors trained in a specific branch of internal medicine are commonly referred to by the branch of their subspecialty specialization. For instance, doctors specializing in heart ailments are referred to as “cardiologists”, whilst doctors of pulmonary issues are called “pulmonologist”.

All of those listed above received the same foundational internal medicine training and are categorized as “internists” just like general internists. An internist who subspecializes in a particular medical field undergoes extensive and in-depth training that equips them to handle extremely complex medical conditions and, in many cases, carry out difficult clinical procedures.

Roles of Internist 

Following are the most common roles of internists:

Adolescent Medicine

In addition to meeting the basic medical needs of teenagers, they also offer care for eating disorders, sports medicine, substance abuse, chronic illnesses, and many more.

Allergy And Immunology

Allergy and immunology specialists are specially trained to identify, manage, and treat conditions including immunologic disorders, allergies, and asthma. Some other cases are also included in this situation such as. adverse reactions to foods and insect stings. Immunologists and allergists treat patients of all ages and treat a wide range of illnesses. These doctors have the option of pursuing jobs that are primarily clinical in nature or ones that are more research oriented.

Critical Care Medicine

Critical care doctors are skilled at identifying and caring for seriously ill or injured patients, including those who have undergone trauma. Nevertheless, this is not always the case, many of these doctors specialize in treating a specific group of patients or kind of illness. The intensive care units are where critical care doctors spend most of their time working (ICUs). While some choose to specialize in critical care as a stand-alone discipline, it’s more typical for doctors to combine this specialty with a focus in nephrology or pulmonology.

Cardiovascular Disease

Physicians that focus on cardiovascular disease are known as cardiologists, and they are experts in conditions affecting the heart and blood arteries. One of the most well-known internal medicine subspecialties, practitioners in this area treat heart failure, irregular cardiac rhythms, and coronary artery disease. Cardiologists concentrate on preventive measures in addition to treating and removing current diseases.

Clinical Cardiac Electrophysiology

Clinical cardiac electrophysiologists are cardiologists who specialize in treating patients with complicated rhythm problems. These medical professionals frequently employ drugs, imaging, and implantable electrical devices like pacemakers.

Geriatric Medicine

General internists treat patients of all ages, whereas geriatricians only treat the elderly. They have extensive knowledge of both the ageing process and the various medical complications that older individuals frequently deal with. To ensure that their patients’ needs are satisfied in a variety of settings, they must also communicate with family members and caregivers.

Infectious Disease

Hepatitis and the human immunodeficiency virus are two examples of diseases brought on by microorganisms that infectious disease specialists remove from diagnosing and treating (HIV).

They work to determine the origin of an infection and assist in creating a successful treatment strategy. These doctors can pursue careers in clinical practice, epidemiology, public health, and other areas because the profession is so diverse.

Medical Oncology

Although medical oncologists most frequently deal with treating cancer, they also work with benign tumors. They collaborate with surgeons and other medical professionals to treat cancer in addition to administering medicines. Medical oncologists frequently operate as the first point of contact for cancer patients, and as a result, they frequently form personal bonds with the people they treat.


Nephrologists who began their careers as internists concentrate on treating renal diseases in their practices.  This includes complicated illnesses that need dialysis, a procedure that helps remove toxins from the blood when the kidneys are not able to work properly.  They treat both patients with minor illnesses and those who have more serious illnesses that could eventually call for a transplant.

Bottom Line

A four-year medical school graduate must complete an internal medicine residency, which typically lasts three years, in order to practice medicine. After completing general internal medicine residency training, a doctor can start practicing internal medicine. An individual can also decide to subspecialize in a specific branch of internal medicine, such as cardiology or infectious diseases. Fellowship training, also known as subspecialty training, requires an additional two to three years of education.
