Many medical professionals specialise in treating a certain sickness or organ... but internists are general practitioners who see adult patients for all of their medical requirements. They typically serve as primary care physicians or inpatient doctors known as hospitalists. These physicians are specialists in medical disorders affecting the important organs of the abdomen and chest. They do, however, treat illnesses that affect other parts of the body, such as the joints and the brain. Primary care internists... work at outpatient clinics. They diagnose and treat common health issues, as well as assist patients in managing chronic illnesses such as diabetes or high blood pressure. They prescribe medications and offer advise on illness prevention, such as which vaccines to receive and healthy eating options. They also keep track of patients' test results, exam notes, and medical history. Internists may care for patients in clinics for several years or visit them only once in urgent care settings. They are constantly exposed to infectious infections and must be able to deal with difficult conditions when caring for critically ill or dying patients. After college, internists must complete four years of medical school and three years of residency training. Long hours, night shifts, and erratic schedules are all part of the training process. General internists may choose to specialise in areas such as cardiology or gastrointestinal.
