Internal Medicine Services

Internal medicine physicians, or internists, provide general primary care to adults.

Whether you need an annual physical, routine preventive care like a flu shot or Medicare Wellness visit, diagnostic services or ongoing disease management for a chronic medical condition, Fallbrook Healthcare Partners is here for you. As an internal medicine physician, Richard Reynolds III, MD, provides his patients with continuity, which is why many people believe chronic diseases are best treated by internal medicine physicians who are trained for that role.

Dr. Reynolds diagnoses and treats a wide range of diseases, conditions and illnesses, including:


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

Chronic Obstructive Pulmonary Disease (COPD)

COPD is a progressive disease that makes it harder for you to breathe. There are two types of COPD: chronic bronchitis and emphysema. Each type can cause many symptoms, including a cough that produces mucus, wheezing, shortness of breath and chest tightness. While there is no cure for COPD, treatments can help relieve symptoms. Treatment options include medication, oxygen therapy, surgery and lung transplant.


Dr. Reynolds provides care for many common infections, including pneumonia and the flu.

Pneumonia is an infection of one or both lungs that can be caused by bacteria, a virus or by inhaling a liquid. Symptoms may 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. Vaccines are available to help prevent some types of pneumonia.

Influenza, or the flu, is a respiratory infection caused by a virus. Millions of people get sick from the flu every year. Symptoms are generally worse than the common cold and can 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 Centers for Disease Control recommends annual flu shots.


Diabetes is a metabolism disorder where the body is unable to appropriately regulate its blood glucose levels. Glucose, a simple sugar, comes from eating carbohydrates. The body creates and stores glucose to use as energy. For glucose to enter cells and be transformed into energy, insulin (a hormone produced in the pancreas) must be present. With diabetes, the pancreas either produces little or no insulin, or the body doesn’t respond to the insulin it produces. Whatever the cause, glucose isn't getting into the body's cells and blood glucose levels in the blood become elevated. Uncontrolled high blood sugar levels can damage many organs of 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, including 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. Healthy lifestyle changes, such as eating a healthy diet, exercising more, quitting smoking, maintaining a healthy weight and managing stress can help lower blood pressure. There are also several 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. Dr. Reynolds can diagnosis and treat a wide range of heart diseases and conditions and coordinate with other healthcare professionals, including surgeons and emergency care physicians, as needed.
