Asthma in Children (cont.)

Asthma is often difficult to diagnose in infants. However, in older children the disease can often be diagnosed based on your child's medical history, symptoms, and physical exam.

• Medical history and symptom description. Your child's doctor will be interested in any history of breathing problems you or your child may have had, as well as a family history of asthma, allergies, a skin condition called eczema, or other lung disease. It is important that you describe your child's symptoms -- cough, wheezing, shortness of breath, chest pain or tightness -- in detail, including when and how often these symptoms have been occurring.



• Physical exam. During the physical examination, the doctor will listen to your child's heart and lungs.



• Tests. Many children will also have a chest X-ray and pulmonary function tests. Also called lung function tests, these tests measure the amount of air in the lungs and how fast it can be exhaled. The results help the doctor determine how severe the asthma is. Generally, children younger than 5 are unable to perform pulmonary function tests. Thus doctors rely heavily on history, symptoms and examination in making the diagnosis.

Other tests may also be ordered to help identify particular asthma triggers. These tests may include allergy skin testing, blood tests and X-rays to determine if sinus infections or gastroesophageal reflux disease (a gastrointestinal condition that causes reflux of acid stomach contents into the esophagus or even into the lungs) is complicating asthma.
