What Is Medical?
Medical is the branch of health care that deals with diseases, their diagnosis, treatment and prevention. Physicians who specialize in this field are called doctors of medicine (MD). Medical practitioners must be licensed, which involves graduating from medical school and passing national exams to become a doctor. Licensing is important for separating qualified doctors from charlatans that practice unproven methods of healing.
In modern times, a wide range of medicines have been developed to treat diseases and illnesses. Some examples are vaccines and antibiotics. In addition, procedures such as surgery and radiology have become increasingly sophisticated.
Medicine is a vast field with many sub-disciplines and specialty areas. For example, internal medicine encompasses the study of various organ systems and their disorders and is often broken down into several sub-specialties such as gastroenterology, endocrinology, hematology, infectious disease and oncology.
A doctor trained in hematology is an expert in blood cell development and function. Hematologists are also concerned with the causes and treatments of disease through blood transfusions and other therapies.
Anatomy is the study of body structure, and it is divided into a number of sub-fields such as cytology, embryology, endocrinology, histology and pathology. Anatomy has long been considered a cornerstone of the biological sciences.
Other fields of medicine are pharmacology, which is the study of drug action and distribution in the body, and veterinary medicine, which deals with the health of animals. Then there are forensic and conservation medicine, diving medicine and evolutionary medicine, to name just a few.
The medical field is constantly changing and developing. New technologies and advances are helping to diagnose diseases more accurately, so patients can be treated sooner and more effectively. For instance, some hospitals are now offering MRI scans to patients who are considered healthy, in order to detect potential problems before they develop. And, the latest developments in 3D printing have enabled doctors to create external prosthetics and cranial implants.
Most countries provide universal health care or have a form of it. This is generally based on a single-payer system and may be supplemented by private insurance. In the United States, the government provides health insurance for all citizens through the Affordable Care Act (ACA). The ACA has increased access to medical services and reduced costs by expanding Medicare eligibility to people over 65 and by encouraging the use of preventive services. It has also improved the quality of health care by reducing hospital admissions and readmissions. The ACA has been controversial, however, because it reduces the power of individual physicians and allows for more cost sharing between insurers and patients. This has led to criticism of the ACA from both sides of the political spectrum.
