A physical examination is a routine check-up performed by a doctor to assess a person's overall health. During this process, the doctor will look for any signs of illness or health issues. They may check vital signs like blood pressure, heart rate, and temperature, as well as examine different parts of the body, such as the heart, lungs, and abdomen. These examinations are important for early detection of potential health problems. They can help identify conditions like diabetes or high cholesterol before they become serious. Regular physical exams are a key part of maintaining good health and ensuring that any necessary treatments can be started promptly.
