Answering your questions about internal medicine doctors

Internal medicine doctors are also known as internists. They specialize in the prevention, diagnosis and treatment of conditions and diseases in adults 18 and older. Internal medicine physicians provide general medical care and help patients manage chronic and complex conditions, such as hypertension and diabetes. When needed, your internal medicine doctor will provide referrals to specialists.

As primary care providers, internal medicine physicians help you manage your health.


Services include:


  • Preventive screenings
  • Routine, annual check-ups
  • Health risk assessment
  • Personalized counseling on maintaining a healthy lifestyle
  • Management of chronic conditions, such as diabetes, asthma and high cholesterol
  • Regular gynecological screenings, such as breast exams and Pap smears
  • Referrals to and coordination with specialists


Our internists are board-certified by the American Board of Internal Medicine (ABIM), and many have additional training or a clinical interest in men's health, women's health, sports medicine and geriatrics.

Preventive health screenings

Preventive care is essential for your health. Most conditions can be prevented or treated effectively when detected early. Your primary care doctor will create your personalized screening schedule based on your age, health, family history and unique risk factors. And with MyScripps, the patient portal, you will know when it is time for your next test.

Regular cervical cancer screening catches problems early by detecting changes in cervical cells before they turn into cancer. Your doctor will use a Pap test or a human papillomavirus test (HPV) to screen for cervical cancer. 

  • Start screenings at age 21 to age 65.
  • Health experts recommend screening every three to five years, depending on age and type of test. 
  • There are two main screening tests: the Pap smear and the HPV test.
  • Early cervical cancer usually does not have symptoms.

Early detection of breast cancer is key to treating it before it has a chance to grow or spread. Early detection is vital because that is when there are the most options for successful treatment. Your doctor can recommend screening options for you, based on family history and other risk factors. 

  • Breast cancer is the most diagnosed cancer in the United States.
  • Start screenings at age 40 or 45 depending on risk factors.
  • Screening is recommended every one to two years. 
  • Mammograms are the main screening tool used to detect breast cancer.

Colorectal screening is crucial because it can detect precancerous polyps that can be removed before they turn into cancer. Regular screening can also find signs of cancer early, when the cancer is easier to treat. Talk with your primary care doctor about which screening is right for you.

  • Colon cancer is the 4th most common cancer in the United States.
  • Start screenings at age 45.
  • Early stages of colorectal cancer do not always cause symptoms.
  • There are several screening options available.

High blood pressure, also called hypertension, affects nearly half of adults in the United States. It is one of the most common conditions screened for during routine visits and a leading risk factor for heart disease, stroke and other serious health conditions. Checking blood pressure regularly allows providers to detect problems early and help patients take steps to protect their long-term health.

  • High blood pressure often has no symptoms.
  • The standard guideline is to have blood pressure checked once a year.
  • Healthy lifestyle factors, such as exercise and eating well, can help prevent and treat high blood pressure. 
  • A healthy blood pressure reading is less than 120/80.
