A routine physical exam is a preventive health visit where your doctor checks your body for signs of disease, measures key health markers, updates your screenings, and reviews your overall well-being. Even if you feel perfectly healthy, the visit establishes a baseline so changes can be caught early. Most physicals take 15 to 30 minutes, though the specifics vary depending on your age, sex, and health history.
What Happens During the Exam
Your doctor uses four basic techniques to evaluate your body. They visually inspect your skin, eyes, ears, and general appearance. They listen to your heart, lungs, and abdomen with a stethoscope. They feel areas like your neck, abdomen, and lymph nodes with their hands to check for swelling, tenderness, or abnormal masses. And they may tap on your chest or back to assess your lungs and other organs by the sound produced.
Beyond those hands-on techniques, your doctor will likely check your reflexes by tapping below the knee and at other joints, observe your posture and the way you walk, and test basic muscle strength and joint mobility. These quick checks help flag neurological or musculoskeletal problems that haven’t caused obvious symptoms yet.
Vital Signs and What the Numbers Mean
Four measurements form the core of every physical. Your doctor records your body temperature (normal is roughly 97.7 to 99.5°F), heart rate (60 to 100 beats per minute for adults), breathing rate (12 to 20 breaths per minute), and blood pressure.
Blood pressure deserves special attention because it’s one of the most actionable numbers you’ll get. Under the current guidelines from the American Heart Association and American College of Cardiology, the categories break down like this:
- Normal: below 120/80 mm Hg
- Elevated: 120 to 129 systolic (top number) with the bottom number still under 80
- Stage 1 hypertension: 130 to 139 systolic or 80 to 89 diastolic
- Stage 2 hypertension: 140 or higher systolic, or 90 or higher diastolic
Healthy adults should have their blood pressure checked every one to two years. If your reading falls into an elevated or hypertensive range, your doctor will discuss lifestyle changes or follow-up monitoring.
Blood Tests Your Doctor May Order
A physical often includes bloodwork, either drawn at the visit or at a lab beforehand. The most common panel is a complete blood count, which measures your red blood cells, white blood cells, and platelets to screen for anemia, infection, and clotting issues. A comprehensive metabolic panel checks your blood sugar, kidney function, liver enzymes, and electrolyte levels. Many providers also order a lipid panel to evaluate cholesterol and triglycerides, especially if you’re over 40 or have risk factors for heart disease.
You may be asked to fast for 8 to 12 hours before certain blood draws, particularly if your doctor wants an accurate fasting blood sugar or triglyceride level. Your office will let you know in advance.
Age-Based Cancer Screenings
One of the most important functions of a routine physical is keeping your cancer screenings on schedule. The specific tests depend on your age and sex.
Cervical cancer screening starts at age 21 for women. From 21 to 29, a Pap test every three years is standard. From 30 to 65, you can choose a Pap test every three years, an HPV test every five years, or both tests together every five years. If you’ve had a total hysterectomy and no history of cervical precancer, screening is no longer needed.
Breast cancer screening with mammography generally isn’t recommended before age 40 for women at average risk. If you have a strong family history, particularly a mother or sister diagnosed at a young age, or carry a high-risk genetic marker, your doctor may recommend starting earlier with mammograms, MRI, or ultrasound.
Colorectal cancer screening begins at age 45 for both men and women, per the U.S. Preventive Services Task Force. Several options exist, from stool-based tests you do at home to a colonoscopy. Regular screening continues through age 75.
For men, prostate cancer screening is no longer automatic. The PSA blood test is an option for men aged 55 to 69 after a conversation with their doctor about the benefits and potential harms, including the risk of overtreatment. Men under 55 generally aren’t screened unless they have a family history of prostate cancer or are African American, both of which raise risk. Routine physical exams of the prostate and testicular screening exams are no longer recommended for men without symptoms.
What’s Different for Medicare Patients
If you’re on Medicare, the yearly “Wellness” visit is not the same as a traditional physical exam. The wellness visit focuses on preventive planning: you’ll fill out a health risk assessment questionnaire, review your medications, go over your family history, get routine measurements like height, weight, and blood pressure, and receive a personalized screening schedule. It also includes a cognitive assessment to check for early signs of dementia, plus a review of substance use risk factors including opioids, alcohol, and tobacco.
Medicare covers the wellness visit at no cost to you. But if your doctor performs a full hands-on physical exam or orders additional tests beyond what’s covered under the wellness visit, you may owe out-of-pocket costs for those services.
Insurance Coverage for Preventive Visits
Under the Affordable Care Act, most private health insurance plans must cover specified preventive services without any cost sharing. That means no copay, no deductible, and no coinsurance for the preventive components of your physical. This applies to services like blood pressure screening, certain blood panels, and recommended cancer screenings. If your visit goes beyond standard preventive care, for instance if your doctor diagnoses a new condition and orders extra tests, those portions may be billed separately.
How to Prepare
Showing up prepared makes the visit more useful. Bring a list of every medication and supplement you take, including dosages. Write down any symptoms you’ve noticed, even minor ones you’ve been brushing off. Know your family medical history, especially conditions like heart disease, diabetes, or cancer in parents or siblings. If you’ve had recent lab work or imaging done elsewhere, bring those results or have them sent to your doctor’s office ahead of time.
Wear loose, comfortable clothing since you’ll likely need to change into a gown. If bloodwork requires fasting, schedule a morning appointment so you’re not skipping meals deep into the afternoon. Have your questions ready in advance. Your physical is one of the few appointments built around prevention rather than a specific problem, so it’s the right time to ask about anything that’s been on your mind.
