Asthma is a chronic lung condition which causes narrowing and inflammation of the airways. Symptoms of asthma are wheezing, coughing, tightness in the chest and shortness of breath. Asthma affects people of all ages, though it commonly begins in childhood. With proper prevention and treatment measures, asthma can be managed well.

Chronic Cough

A chronic cough is a cough that persists for eight weeks or more. Chronic cough most frequently arises due to postnasal drip, asthma and acid reflux. Treatment for chronic cough is aimed at eliminating the underlying cause.

Chronic Bronchitis

Chronic (recurrent) bronchitis is a long-term respiratory illness that causes an inflammation of the lining of the bronchial tubes, which carry air to and from the lungs. This inflammation results in a build-up of mucus in the airways, causing breathing difficulties and a heavy cough that produces mucus from the lungs. Smoking is the main cause of chronic bronchitis. This disease can be managed through medical treatment and lifestyle changes.

Atopic Dermatitis

Atopic dermatitis is type of eczema which causes itchy, red, swollen and cracked skin. It typically affects the insides of the elbows, backs of the knees and the face, but can cover most of the body. Atopic dermatitis most commonly appears in infants and children, though many people outgrow the condition as they get older. The cause is not known, but seems to have a genetic link and is often seen in people who have a family history of the condition.

Patient Education

Who should see an allergist?

If you have asthma or allergy symptoms that interfere with your daily life, such as sneezing, nasal congestion, coughing or wheezing, a visit to an allergist can be beneficial. An allergist will be able to diagnose and provide treatment options, as well as educate you on how to prevent and manage flare-ups in the future. Under the care of an allergist, most patients will find that their quality of life is greatly improved and they can feel in control of their allergies and asthma, giving them the freedom to live life to the fullest.

What is a Board Certified allergist?

A Board Certified allergist is a physician who attended an accredited medical school, completed a residency in medicine and then completed an additional fellowship or training program in allergy, asthma and immunology. A Board Certified allergist has taken and passed a national board examination in both Internal Medicine as well as in Allergy and Immunology, making him or her a specialist in the diagnosis and treatment of asthma, allergies, and other immune system conditions. A Board Certified doctor must continue his or her medical education through yearly classes and seminars. By choosing a Board Certified allergist for your care, you are choosing an expert.
