Physicals are an important part of preventive health care. They involve a comprehensive checkup and physical examination to assess a person's overall health. A physical exam typically includes a review of medical history, a physical examination, and laboratory tests. During a physical exam, the doctor will check vital signs such as blood pressure, heart rate, and temperature. The doctor may also perform a variety of tests, such as a urinalysis or blood test, to check for any underlying health issues. Physicals are important for detecting potential health problems early on and can help people stay healthy and prevent serious illnesses.
