Internal Medicine


Primary Care for Adults

Internists are physicians who diagnose and medically treat diseases and provide primary care for adults. They handle routine medical issues as well as complicated problems. Internists offer screening for patients at risk for cancers, including breast cancer, prostate cancer and colorectal cancer, among other conditions. They will refer you to a specialist if it is determined to be necessary.

Our internal medicine physicians diagnose and treat a variety of conditions, including:


Asthma is a chronic disease where the airways become inflamed and swollen, which makes breathing difficult. Patients with asthma may experience a range of symptoms, including wheezing, coughing, chest tightness and shortness of breath. While there is no cure for asthma, treatment and medication can help manage and prevent symptoms.


We provide care for many common infections, including pneumonia and the flu.

Pneumonia is a lung infection that’s caused by bacteria, a virus or by inhaling a liquid. Symptoms include fever, cough, shortness of breath and chest pain. Pneumonia can be a serious condition, especially in young children, older adults and people with other health issues. There are vaccines to help prevent some types of pneumonia.

The flu (influenza) is a respiratory infection caused by a virus. Symptoms are usually worse than the common cold and may include body aches, chills, fever, headache and sore throat. While most people will recover from the flu on their own, the condition can cause serious complications. The CDC recommends annual flu shots.


Diabetes is a disorder where the body can’t properly regulate its blood glucose levels. Glucose, which is a simple sugar, comes from eating carbohydrates. The body creates and stores glucose to use as energy. Insulin is needed for glucose to enter cells and be transformed into energy. With diabetes, the pancreas either produces little or no insulin, or the body doesn’t respond to the insulin it produces. Whatever the case, glucose doesn’t get into the body’s cells and blood glucose levels in the blood become elevated. Uncontrolled high blood sugar levels can be very harmful to the body.

High Blood Pressure

High blood pressure, or hypertension, is a common condition where the blood flows through the veins or arteries at a higher pressure than normal. If left untreated, high blood pressure can lead to serious issues, such as heart attack, heart failure, stroke and kidney failure. A blood pressure reading of 140/90 or higher is generally considered high. A reading of 180/120 is considered dangerously high and requires immediate attention. Eating a healthy diet, exercising more, quitting smoking, maintaining a healthy weight and managing stress can help lower blood pressure. There are also medications that can help lower blood pressure if lifestyle changes alone are not effective.

Heart Disease

Heart disease is the leading cause of death in the United States, according to the CDC. In addition, the American Heart Association estimates that one in five Americans have some form of cardiovascular disease. Our physicians can diagnosis and treat many heart diseases and conditions and coordinate with other healthcare professionals as needed.
