Internal Medicine Q & A

What is internal medicine?

Internal medicine is a medical subspecialty that diagnoses, treats, and prevents complex health problems in adults. The internal medicine providers at Signature Internal Medicine boast years of experience treating acute and chronic issues using a conservative and patient-centric approach.

Whether you recently moved to the area or it’s been more than a year since you last visited the doctor, Signature Internal Medicine can help.

What services does internal medicine provide?

Signature Internal Medicine offers a wide range of internal medicine services, including:

Physical exams

A physical exam assesses your general well-being. During a physical, your provider examines your skin; checks your ears, nose, and throat; listens to your heartbeat and respiratory rate; gently palpates your abdomen to determine the size and location of your organs; and tests your reflexes and blood pressure. 


Immunizations, or vaccines, teach your immune system to identify pathogens like viruses and bacteria. That way, if you encounter a specific illness in the future, your body knows how to respond. Staying up-to-date on your immunizations is one of the easiest ways to protect your health and the health of others.

Lab tests

Lab tests analyze your bodily fluids, like blood, saliva, or urine, to get information about your health. Signature Internal Medicine uses lab tests to diagnose a variety of health problems, including high cholesterol, kidney disease, and diabetes.

Referrals to specialists

Signature Internal Medicine treats most acute and chronic health problems, but if you require more individualized care, they can refer you to a nearby specialist.

Referrals for diagnostic imaging

If you suffer a sports injury, and Signature Internal Medicine suspects a fracture or a dislocated joint, they might recommend diagnostic imaging. If necessary, your provider can refer you to a nearby radiology facility for X-rays, an ultrasound, or an MRI. You may also be referred for diagnostic imaging for other concerns or screening purposes. 

Prescription medication 

Signature Internal Medicine recommends conservative treatment whenever possible, but if your symptoms don’t respond to healthy lifestyle changes, medication might be necessary. Signature Internal Medicine regularly writes prescriptions and provides refills.
