A comprehensive physical examination usually includes four categories: physical examination, laboratory examination, imaging examination, and specialized examination. It specifically covers basic items such as general examination, blood routine, urine routine, liver function, kidney function, blood lipids, blood glucose, electrocardiogram, abdominal ultrasound, chest X-ray, as well as targeted screening based on age, gender, and personal health status. Physical examination is the basic part of physical examination, including measuring height, weight, blood pressure, pulse, as well as visual and auditory examinations by specialists in internal medicine, surgery, ophthalmology, otolaryngology, dentistry, and other fields. In laboratory tests, blood routine can evaluate the presence of anemia, infection, or hematological disorders; Urinalysis can screen for kidney and urinary system problems; Biochemical tests such as liver function, kidney function, blood lipids, and blood glucose reflect the metabolic function of the liver and kidneys and the risk of cardiovascular disease. Abdominal ultrasound is the most common imaging examination, which can observe the structures of organs such as the liver, gallbladder, pancreas, spleen, and kidneys; Chest X-rays are used to screen for lung inflammation, tuberculosis, or space occupying lesions. Electrocardiogram is a routine method for evaluating cardiac electrical activity, which helps to detect arrhythmias or myocardial ischemia. The physical examination items will be focused on different groups of people. For example, people over 40 years old often undergo gastroscopy to screen for gastrointestinal tumors; Women need to undergo breast ultrasound or mammography, gynecological examination, and cervical cancer screening; Men can increase their prostate-specific antigen testing. Long term smokers, patients with a family history or chronic diseases may be advised by doctors to undergo in-depth examinations such as low-dose lung CT, carotid artery ultrasound, or cardiac ultrasound. In addition, thyroid function, bone density, tumor markers, etc. are often included as optional items in the physical examination package. Before the physical examination, it is usually required to fast for 8 to 12 hours, avoid high-fat diet and alcohol consumption, and women should avoid the menstrual period to ensure the accuracy of the results. After completing the full body physical examination, it is recommended to keep the report properly and regularly communicate with the doctor to interpret the results. For abnormal indicators, do not be overly anxious, but follow medical advice for follow-up or further specialized examinations. In daily life, maintaining a balanced diet, regular exercise, adequate sleep, and a positive mindset are the foundation for maintaining good health. The significance of physical examination lies in early detection of potential risks, rather than replacing daily health management. Therefore, conducting a systematic physical examination once a year or every two years, adjusting items according to one's own situation, is a healthy habit worth adhering to.
