Medicine

Medicine (also called healthcare or human health) is the science and practice concerned with diagnosis, treatment, and prevention of disease and injury of the body and mind. It combines knowledge from biological science with practical skills applied in caring for patients.

Medical practice is based on a standard procedure: the patient's history is recorded, a physical examination is performed, tests (such as blood analysis or imaging) are used, and then a treatment plan is decided based on the findings. The outcome is monitored and the plan is adjusted as needed.

Major Branches

Medicine divides into several branches. Internal medicine deals with diseases in adults that are not treated by surgery. Surgery involves physical intervention. Other branches include pediatrics, obstetrics and gynecology, psychiatry, and emergency medicine. There are also supporting disciplines such as nursing, pharmacy, and nutrition.

Public Health and Prevention

A large part of medicine extends beyond individual treatment. Public health focuses on vaccination, clean water, nutrition, and surveillance of infectious disease. These measures often reduce the burden on hospitals by preventing disease from spreading widely.

Brief History

Medical knowledge developed from various traditions: ancient Egypt, ancient Greece, India, China, and Islamic scholarship, including works by Ibn Sina that were studied for centuries. In later centuries, understanding of germs, principles of surgical hygiene, antibiotics, and randomized clinical trials transformed how medical decisions are made.

Training and Ethics

Physicians undergo university education followed by extended on-the-job training, internships, and professional supervision. Medical ethics is based on informed patient consent, patient confidentiality, avoidance of harm, and fair distribution of care.
