A general medical exam is a routine visit with a primary care provider designed to evaluate your overall health, catch potential problems early, and update preventive care like screenings and vaccines. Unlike a visit for a specific complaint (a sore throat, back pain), this exam looks at the big picture: how your body is functioning, what risks you might face based on your age and history, and whether you’re up to date on recommended health maintenance.
What Happens During the Visit
The exam typically starts with a set of vital sign measurements. A nurse or medical assistant will check your blood pressure (normal falls between 90/60 and 120/80 mmHg), pulse (60 to 100 beats per minute at rest), breathing rate (12 to 18 breaths per minute), and temperature (averaging around 98.6°F). Your height and weight are recorded to calculate your body mass index, or BMI, which is grouped into categories: healthy weight (18.5 to 24.9), overweight (25.0 to 29.9), and obesity (30.0 or higher).
From there, your provider performs a hands-on physical examination. This usually includes listening to your heart and lungs with a stethoscope, feeling your abdomen for organ abnormalities, checking reflexes, examining your eyes, ears, nose, and throat, and palpating lymph nodes in your neck. Depending on your age and sex, the exam may also include a breast exam, pelvic exam, or testicular check. The specifics vary from provider to provider, but the goal is the same: look for anything abnormal that you might not have noticed yourself.
You’ll also spend time talking. Your provider will review your medical history, ask about any new symptoms or health changes since your last visit, go over your current medications and supplements, and update your family health history. This conversation is often the most valuable part of the visit because it shapes which screenings and tests your provider recommends going forward.
Common Lab Tests
Blood and urine tests give your provider a window into health issues that don’t produce obvious symptoms. A comprehensive metabolic panel measures things like blood sugar, kidney function, and electrolyte balance, offering a broad snapshot of how your organs are performing. A complete blood count checks your red and white blood cells and can flag infections, anemia, or immune system issues.
Cholesterol screening is one of the most common tests ordered during a general exam. The American Heart Association recommends starting cholesterol checks at age 20 for people without known risk factors, then repeating every four to six years. If results come back elevated, your provider may recommend more frequent monitoring. Diabetes screening typically begins at age 35 for people who are overweight, with repeat testing every three years.
Not every visit requires bloodwork. Your provider decides which tests are appropriate based on your age, sex, risk factors, and how recently you were last tested. If fasting blood tests are ordered, you’ll need to avoid eating or drinking for 8 to 12 hours beforehand.
Preventive Screenings by Age
One of the primary purposes of a general exam is making sure you’re current on age-appropriate cancer screenings and other preventive checks. The U.S. Preventive Services Task Force maintains a list of recommended screenings rated by the strength of evidence behind them. Screenings rated “A” or “B” have strong evidence of benefit and are the ones your provider will prioritize.
In your 20s and 30s, screenings tend to focus on reproductive and sexual health. Cervical cancer screening with a Pap test is recommended every three years starting at age 21. After age 30, you can switch to a Pap test every three years, an HPV test every five years, or both tests together every five years. Sexually active women under 25 should be screened for chlamydia and gonorrhea. A one-time HIV test is recommended for everyone between ages 15 and 65, and a one-time hepatitis C test for adults ages 18 to 79.
Starting in your 40s and 50s, the focus shifts toward chronic disease and cancer detection. Colorectal cancer screening typically begins at age 45. Mammograms, blood pressure checks, and diabetes screening become more routine. Blood pressure should be checked at least every three to five years for younger adults, and more frequently as you age or if readings trend upward. Eye exams are recommended every 5 to 10 years before age 40, then more often after that.
Mental Health and Mood Screening
Many primary care providers now screen for depression and anxiety as a standard part of a general exam. You may be asked to fill out a short questionnaire in the waiting room or on a tablet before your visit. The two most widely used tools are the PHQ-9 for depression and the GAD-7 for anxiety. Both are brief, usually nine or seven questions respectively, and ask you to rate how often you’ve experienced specific symptoms over the past two weeks.
These screenings aren’t a diagnosis on their own. They flag potential concerns so your provider can follow up with a more detailed conversation. If your scores suggest moderate or severe symptoms, your provider may discuss treatment options or refer you to a mental health specialist.
Vaccines Your Provider May Recommend
Your provider will review your immunization history and recommend any vaccines you’re due for. The CDC’s adult immunization schedule is organized by age and medical conditions. A yearly flu shot is recommended for all adults. COVID-19 vaccines follow an updated schedule with one or more doses of the current formulation. Beyond those, your provider may bring up vaccines you received years ago that need boosters, like tetanus (due every 10 years), or vaccines that become relevant at certain ages, like shingles (typically recommended at 50) or pneumonia vaccines for older adults or those with chronic conditions.
How a General Exam Differs From a Wellness Visit
If you have Medicare, there’s an important distinction worth understanding. Medicare covers an Annual Wellness Visit, but this is not the same thing as a traditional physical exam. The wellness visit focuses exclusively on preventive care: reviewing your screenings, updating your health risk assessment, and checking that you’re current on vaccines. It does not include a hands-on physical exam like listening to your heart and lungs or examining your abdomen. As the American Medical Association has noted, Medicare created this benefit because it had never previously covered a routine annual physical, only problem-based visits. If you want a full physical exam on top of the wellness visit, that may involve additional charges.
For people with private insurance, the Affordable Care Act requires most plans to cover preventive services without a copay. However, if your provider addresses a specific health concern during the same visit (say, you mention knee pain and they order an X-ray), that portion may be billed separately.
How Often You Need One
There’s no single rule for how frequently you should have a general exam. For healthy adults in their 20s and 30s with no chronic conditions, every two to three years is a common recommendation. Once you hit your 40s, annual visits become more useful because more screenings come into play and chronic disease risks rise. After 50, most providers recommend yearly exams. If you have an ongoing condition like diabetes, high blood pressure, or heart disease, you’ll likely see your provider more often than once a year regardless of age.
How to Prepare
A little preparation makes the visit more productive. Bring a list of all medications and supplements you’re taking, including doses. If your provider sent any forms ahead of time, fill them out before you arrive. Wear comfortable clothing that’s easy to change out of if you need to put on a gown.
Write down your questions in advance. It’s easy to forget what you wanted to ask once you’re in the exam room. Good questions to consider: Are there lifestyle changes that could lower my specific health risks? Am I taking my medications correctly? Are there any new screenings I should be getting at my age? Also note anything that’s changed since your last visit, including surgeries, injuries, new symptoms, or vaccines you received elsewhere (like a flu shot at a pharmacy). Updating your family health history is equally important, especially if a close relative has been diagnosed with cancer, heart disease, or diabetes since your last appointment.
