A physical exam is a head-to-toe evaluation where your doctor checks your vital signs, examines your major organ systems, and orders screening tests based on your age and risk factors. Most annual physicals take 15 to 30 minutes and follow a predictable sequence, though the specific components vary depending on your sex, age, and health history.
Vital Signs Come First
Every physical starts with four basic measurements, usually taken by a nurse or medical assistant before the doctor enters the room. These numbers set the baseline for the rest of your visit:
- Blood pressure: Normal falls between 90/60 and 120/80 mmHg. Readings consistently above 120/80 may prompt follow-up monitoring outside the clinic to confirm whether you have high blood pressure.
- Heart rate: A resting pulse between 60 and 100 beats per minute is typical for healthy adults.
- Breathing rate: 12 to 18 breaths per minute at rest is the normal range.
- Temperature: The average is 98.6°F, with a normal range of about 97.7°F to 99.1°F.
Your height, weight, and body mass index are also recorded at this stage. Together, these numbers give your doctor a quick snapshot of your cardiovascular and metabolic health before the hands-on exam begins.
The Head-to-Toe Exam
Once your doctor comes in, the physical portion typically moves from head to toe. They’ll look into your eyes with a light, check your ears, and inspect the inside of your mouth for sores, swelling, or signs of infection. They’ll ask you to swallow and watch for difficulty. Along the sides of your neck, under your jaw, and in your armpits, the doctor will press gently to feel your lymph nodes for swelling or tenderness, which can signal infection or other issues.
Your skin gets evaluated throughout the exam rather than in one dedicated step. The doctor is watching for unusual color changes (yellowing, bluish tints, unusual redness), dryness, and any suspicious moles or spots.
Heart and Lungs
Using a stethoscope, your doctor listens to your heart from several positions on your chest, checking for irregular rhythms, murmurs, or extra sounds. They’ll then move the stethoscope to your back and ask you to breathe deeply while they listen to each lung. They’re checking for wheezing, crackling, or diminished breath sounds that could point to conditions like asthma, fluid buildup, or infection.
Abdomen
The abdominal exam follows a specific sequence: the doctor first looks at your belly for visible swelling or asymmetry, then listens with a stethoscope for bowel sounds and checks blood flow through major vessels like the aorta. Next comes gentle pressing across all four quadrants of your abdomen. They’re feeling for tenderness, enlarged organs, or unusual masses. The doctor may ask you to take a deep breath while pressing under your right rib cage to feel the edge of your liver as it moves downward.
Reflexes and Basic Neuro Check
The classic knee tap with a reflex hammer is part of a quick neurological screen. Your doctor may also test your arm reflexes, ask you to push and pull against their hands to gauge muscle strength, and have you walk across the room to observe your gait and balance. In some cases they’ll ask you to stand with your eyes closed while they gently nudge you, testing how well your balance system functions without visual input. Joints may be moved through their range of motion, either by you or by the doctor, to check for stiffness or pain.
Sex-Specific Exams
For women, a physical may include a clinical breast exam, where the doctor feels for lumps and checks the lymph nodes under the arms. A pelvic exam allows the doctor to examine the vagina, cervix, uterus, and ovaries for abnormalities or infections. Depending on your age, a Pap test or HPV test may be done at the same time to screen for cervical cancer. Women aged 21 to 29 are generally screened every three years with a Pap test alone, while women 30 to 65 can be screened every three to five years depending on the testing method used.
For men, the exam may include checking each testicle for lumps or tenderness, which serves as a screening measure for testicular cancer. A hernia check involves the doctor feeling near the groin while you cough. Men over 50 are often advised to discuss prostate cancer screening, which can involve a rectal exam where the doctor feels the prostate gland for size and any suspicious areas.
Mental Health Screening
Many primary care offices now include a brief mental health check as part of the annual physical. You’ll likely fill out a short questionnaire in the waiting room or on a tablet. The most common tool is the PHQ-2 or PHQ-9, which asks about feelings of sadness, hopelessness, and loss of interest over the past two weeks. A similar questionnaire called the GAD-7 screens for anxiety. These take under five minutes to complete and are scored on the spot. A score of 10 or higher on either the PHQ-9 or GAD-7 typically flags the need for a more detailed conversation with your doctor about your mental health.
Blood Work and Lab Tests
Your doctor will often order blood tests either before or after the physical exam. The most common panels include a complete blood count (CBC), which measures your red blood cells, white blood cells, and platelets to check for anemia, infection, and clotting issues. A comprehensive metabolic panel evaluates your electrolytes, blood sugar, kidney function, and liver function in one draw. A lipid panel measures your cholesterol and triglycerides.
Some of these tests require fasting for 8 to 12 hours beforehand. During that fasting window, you can drink plain water but should avoid juice, coffee, soda, and even gum. Smoking and exercise can also affect results. If you take prescription medications, ask your doctor at least a day before the test whether to continue them on the morning of your blood draw. Bringing a snack to eat right after is a good idea, since fasting combined with a blood draw can leave you lightheaded.
Age-Based Screenings
Beyond the hands-on exam, your doctor uses your annual physical to make sure you’re current on recommended screenings. These change as you age:
- Blood pressure: Screened at every visit starting at age 18.
- Colorectal cancer: Screening begins at age 45, typically with a stool-based test or colonoscopy.
- Breast cancer: Mammograms every two years for women aged 40 to 74.
- Cervical cancer: Screening for women starting at age 21, with intervals depending on the type of test.
- Lung cancer: Annual low-dose CT scans for adults aged 50 to 80 with a significant smoking history.
Your doctor may also review your family history to determine whether genetic counseling is appropriate, particularly for women with a family history of breast or ovarian cancer linked to inherited gene mutations.
Vaccine Review
Your physical is also when your doctor checks whether your immunizations are up to date. For most adults, this means a flu shot every year, a tetanus booster every 10 years, and COVID-19 vaccines as updated. Adults 50 and older are recommended to receive the shingles vaccine (two doses). Pneumonia vaccines are recommended for older adults and those with certain health conditions. If you missed childhood vaccines like measles, mumps, rubella, or hepatitis B, your doctor may recommend catching up. HPV vaccination is available through age 45 for those who haven’t been vaccinated.
How to Prepare
A little preparation makes your physical more productive. If blood work has been ordered, follow your fasting instructions carefully. Bring a list of all medications, vitamins, and supplements you take, including doses. Write down any symptoms you’ve been meaning to mention, even minor ones, since it’s easy to forget in the moment. If you have records from specialists or recent urgent care visits, bring those too.
Wear comfortable, easy-to-remove clothing. You’ll be asked to change into a gown for most of the exam. The whole visit, including time in the waiting room, typically runs 30 to 60 minutes, though the exam itself is often shorter than people expect.
