Speaking Healthcare: Common Terms and Their Everyday Meanings

Have you ever left a doctor’s appointment and realized you weren’t quite sure what some of the medical terms meant? Or maybe you received lab or test results in your patient portal and found yourself trying to make sense of unfamiliar terminology.

Healthcare has its own language and understanding it can help you feel more informed and prepared when discussing your health with your care team

“Understanding the terminology used during a medical visit can help patients take a more active role in their care,” says Mehwish Khan MD PIH Health family medicine physician. “We want patients to feel comfortable asking questions whenever something isn’t clear. Your healthcare team is there to help you understand your health and the next steps in your care.”

Here are some common healthcare terms and what they mean in everyday language.

• Acute: A condition that begins suddenly and typically lasts for a relatively short period of time. Examples may include a common cold, sprained ankle, or sudden infection.
• Basic Metabolic Panel (BMP): A common blood test that measures eight substances in the blood. It can provide information about blood sugar, kidney function, electrolyte, and fluid balance, and other aspects of your overall health.
• Benign: A term often used to describe a growth or tumor that is not cancerous. A benign growth does not invade nearby tissue or spread to other parts of the body, although some benign conditions may still require monitoring or treatment.
• Biopsy: A procedure in which a small sample of tissue or cells is removed from the body and examined to help diagnose a condition, including determining whether abnormal cells are cancerous.
• Chronic: A condition that lasts for a long period of time or requires ongoing management. Examples include diabetes, high blood pressure, and certain forms of heart disease.
• Complete Blood Count (CBC): A common blood test that measures different components of your blood, including red blood cells, white blood cells, and platelets. A CBC can help healthcare providers evaluate your overall health and look for signs of conditions such as anemia or infection.
• Comorbidity: The presence of two or more medical conditions in the same person at the same time. For example, someone may have both diabetes and high blood pressure.
• Contusion: The medical term for a bruise. A contusion occurs when small blood vessels under the skin are damaged, often following a bump, fall, or other injury.
• Diagnosis: The identification of a disease, condition, or injury based on symptoms, medical history, an examination, laboratory testing, imaging, or other information.
• Edema: Swelling caused by excess fluid building up in the body’s tissues. Edema commonly affects the legs, ankles, and feet but can occur in other areas of the body.
• Fracture: The medical term for a cracked or broken bone. Fractures can range from small cracks to complete breaks and may require different treatments depending on their location and severity.
• Hypertension: The medical term for high blood pressure. Hypertension occurs when the force of blood against the walls of the arteries remains consistently too high. Because it may not cause noticeable symptoms, regular blood pressure checks are important.
• Inflammation: The body’s natural response to injury, infection or irritation. Signs of inflammation may include redness, swelling, warmth, or pain. Inflammation can be short-term or become chronic depending on the underlying cause.
• Inpatient: A patient who has been formally admitted to a hospital for care, typically involving at least an overnight stay. Inpatient care may be needed for surgery, serious illness, injury, or other conditions requiring close monitoring or treatment.
• Lesion: A general term for an area of tissue that looks or functions differently from the surrounding tissue. A lesion can occur on the skin or inside the body and does not necessarily mean cancer. Your healthcare provider may recommend additional evaluation depending on its appearance, location, and other factors.
• Malignant: A term used to describe cancerous cells or tumors. Malignant cells can grow into nearby tissues and may spread to other parts of the body.
• Myocardial Infarction (MI): The medical term for a heart attack. It occurs when blood flow to part of the heart muscle is blocked, which can damage the heart. A heart attack is a medical emergency and requires immediate treatment.
• Negative Test Result: Generally means that the condition, substance, or finding being tested for was not detected. However, what a negative result means can vary depending on the specific test and why it was ordered.
• Outpatient: Medical care that does not require an overnight hospital stay. Examples can include routine doctor visits, imaging tests, laboratory work, and certain procedures or surgeries that allow patients to return home the same day.
• Positive Test Result: This generally means that the condition, substance, or finding being tested for was detected. A positive result does not always provide a complete diagnosis, and additional testing or evaluation may sometimes be needed.
• Prescription: An order from a licensed healthcare provider for a medication or treatment. A prescription typically includes instructions about how much medication to take, how often to take it, and for how long.
• Preventive Care: Healthcare focused on helping prevent illness or detecting health problems early, often before symptoms develop. Examples include routine physical exams, vaccinations, and recommended health screenings.
• Prognosis: An estimate of how a disease or condition may progress, including the expected course of the condition and likelihood of recovery or improvement. A prognosis can change depending on how a patient responds to treatment and other factors.
• Referral: A recommendation or request from a healthcare provider for a patient to see another provider, specialist, or healthcare service for additional evaluation or treatment.
• Screening: A test or examination used to look for a disease or health condition before a person develops symptoms. Examples may include mammograms, colon cancer screenings, and blood pressure checks.
• Symptom: Something a person experiences that may indicate an illness or condition. Examples include pain, nausea, dizziness, headache, or fatigue. Symptoms are generally reported by the patient rather than measured through a test.
• Terminal: A term used to describe an advanced illness that cannot be cured and is expected to eventually result in death. When an illness is terminal, care may increasingly focus on comfort, symptom management, and quality of life.
• Vital Signs: Measurements that provide basic information about how your body is functioning. They typically include body temperature, blood pressure, heart rate, and breathing rate. Depending on the setting, oxygen saturation may also be measured.

The same applies to test and lab results. A result viewed on its own may not tell the full story and often needs to be considered alongside your medical history, symptoms, and other findings. Don’t be afraid to talk with your healthcare provider about what your results mean specifically for you and whether any follow-up is needed.

Understanding common healthcare terms can help you take a more active role in your care. When in doubt, ask questions and talk with your healthcare team.
