During a routine physical, your doctor checks your body from head to toe, looking for early signs of disease, tracking how your health changes over time, and catching problems before they cause symptoms. The visit typically includes a review of your medical history, a set of vital signs, a hands-on examination of your major organ systems, and blood work or screenings tailored to your age and risk factors.
Medical History and Lifestyle Review
Before anyone touches a stethoscope, the visit starts with questions. Your doctor will review your personal and family medical history, update the list of medications or supplements you take, and ask about lifestyle factors like smoking, alcohol use, diet, and exercise. This conversation isn’t small talk. A parent’s heart attack at 52 or a sibling’s colon cancer diagnosis can shift which tests you need and how early you need them.
You’ll also be asked about any symptoms you’ve noticed since your last visit, changes in sleep or mood, and your general stress level. If something has been bothering you, even if it seems minor, this is the time to bring it up.
Vital Signs
Vital signs are the first measurable data your doctor collects. These include blood pressure, heart rate, respiratory rate, temperature, and often your height and weight to calculate BMI.
Blood pressure is one of the most important numbers. A healthy reading is below 120/80 mmHg. The top number (systolic) reflects the force when your heart beats; the bottom number (diastolic) measures pressure between beats. Consistently elevated readings signal high blood pressure, which raises your risk for heart attack, stroke, and kidney disease, often without any noticeable symptoms. A resting heart rate between 60 and 100 beats per minute is considered normal for adults, though regular exercisers often run lower.
Head, Eyes, Ears, Nose, and Throat
Your doctor will look into your eyes with a small light, checking your pupils’ response and sometimes examining the blood vessels at the back of the eye. Those tiny vessels can reveal early signs of diabetes or high blood pressure before you notice anything wrong. Your ears are checked for wax buildup or signs of infection, and your nose and throat are inspected for swelling, redness, or other abnormalities.
The neck gets attention too. Your doctor will feel along both sides for swollen lymph nodes, which can indicate infection or, less commonly, something more serious. They’ll also palpate your thyroid gland at the base of your throat, checking for enlargement or nodules.
Heart and Lung Exam
Using a stethoscope, your doctor listens to your heart at several points on your chest. They’re checking for irregular rhythms, extra sounds, or murmurs, which are unusual whooshing sounds caused by turbulent blood flow through the heart valves. Most murmurs are harmless, but some warrant further testing.
For the lungs, you’ll be asked to take deep breaths while the stethoscope moves across your upper and lower back. Your doctor is listening for clear, even airflow on both sides. High-pitched whistling sounds (wheezing) can suggest asthma, chronic obstructive pulmonary disease, or a partial airway blockage. Crackling or rattling sounds may point to fluid in the lungs or an infection like pneumonia.
Abdominal Exam
When your doctor presses on your belly, they’re doing more than checking for pain. They work systematically across four quadrants of your abdomen, starting with light pressure and then pressing deeper. The goal is to assess the size and texture of your liver, spleen, and kidneys, and to feel for any unusual masses, hernias, or areas of tenderness.
The liver is felt by pressing upward from your right side toward your ribcage until its edge can be detected. The spleen is checked starting lower and moving toward your left upper abdomen. Your kidneys are examined with a two-handed technique, one hand lifting from behind your flank while the other presses from the front. Your doctor may also feel for the pulse of your abdominal aorta, the large artery running down your midsection, to check for any widening that could signal an aneurysm. The area around your belly button and groin is checked for hernias, especially while you cough or bear down, which makes small bulges easier to detect.
Skin Check
Throughout the exam, your doctor is scanning your skin for anything unusual. They’re looking at moles, birthmarks, and other pigmented spots, noting any that stand out in color, size, shape, or texture. The general rule for concerning moles is asymmetry, irregular borders, uneven color, a diameter larger than a pencil eraser, or any spot that’s evolving over time. Not every physical includes a full-body skin exam, so if you have a mole that’s changed or a family history of skin cancer, mention it so your doctor can take a closer look.
Neurological and Reflex Testing
The classic knee-tap with a small rubber hammer isn’t just tradition. Reflex testing has been part of routine exams for over a century because it reveals a surprising amount about your nervous system quickly and safely. When your doctor taps below your kneecap or at your elbow, they’re checking that the signal travels correctly from the tendon through the nerve, up to the spinal cord, and back to the muscle. Reflexes that are too strong can suggest a problem in the brain or upper spinal cord, while weak or absent reflexes can point to nerve damage in the limbs or lower spine.
Your doctor may also test your balance, coordination, and muscle strength by asking you to push against their hands, walk in a straight line, or touch your nose with your eyes closed.
Routine Blood Work
Most physicals include blood tests, either drawn at the visit or ordered ahead of time so results are ready to discuss. The two most common panels are a complete blood count (CBC) and a comprehensive metabolic panel (CMP).
A CBC measures your red blood cells, white blood cells, and platelets. It can flag anemia, infections, clotting issues, and some blood cancers. A CMP checks your blood sugar, kidney function, liver enzymes, and electrolyte levels like sodium, potassium, and chloride, which help regulate fluid balance and nerve function. Liver-specific markers like ALT and albumin tell your doctor how well your liver is processing waste and producing essential proteins.
A lipid panel is also standard for adults, measuring total cholesterol, LDL (“bad”) cholesterol, HDL (“good”) cholesterol, and triglycerides. These numbers are central to assessing your cardiovascular risk.
Age-Specific and Gender-Specific Screenings
Your physical may include additional screenings depending on your age, sex, and risk factors.
- Mammograms: Recommended for women at average risk starting no earlier than age 40 and no later than 50, repeated every one to two years, and continuing through at least age 74.
- Prostate screening: Men should discuss prostate exams with their doctor by age 50. Black men and those with a family history of prostate cancer should start the conversation at age 45, since both groups face a higher risk.
- Cervical cancer screening: Pap smears are typically recommended starting at age 21, with the frequency depending on your age and previous results.
- Colonoscopy: Colon cancer screening generally begins at age 45 for people at average risk.
- Bone density: Usually recommended for women starting around age 65, or earlier if you have risk factors for osteoporosis.
Your doctor will also review whether your vaccinations are up to date and may recommend flu, pneumonia, shingles, or other shots based on your age and health status.
What You Can Do to Prepare
Bring a list of every medication and supplement you take, including doses. Write down any symptoms or health changes you’ve noticed, even ones you think are probably nothing. Know your family health history, particularly heart disease, cancer, and diabetes in first-degree relatives. If your doctor orders fasting blood work, you’ll typically need to avoid food and drinks other than water for 8 to 12 hours beforehand.
A physical is one of the few medical appointments designed entirely around prevention. The more honest and specific you are during the visit, the more useful it becomes.
