What is a physical examination?

Physical examination is the basic method to understand human health and find and diagnose diseases. Usually, direct inspection, laboratory inspection and special instrument inspection (such as X-ray inspection) are adopted. Doctors must examine patients in the process of diagnosing and treating diseases. Physical examination items depend on needs, generally including physical development (height, weight, etc. ), nutritional status, structural morphology and functional status of various organs and systems of the body, and whether there are abnormalities and changes. Regular or irregular physical examination of healthy people is called health examination.
