While asthma symptoms seem straightforward—coughing, wheezing, and shortness of breath—it’s not always easy for doctors to definitively diagnose the condition. It can be hard to determine if a chronic cough is asthma, a lingering respiratory ailment, or something else. Symptoms like wheezing can come and go, or coughing may only occur at specific times, such as at night or with exposure to pollen or other triggers.
Symptoms of asthma can be mild or severe. Your child may have no symptoms; severe, daily symptoms; or something in between. How often your child has symptoms can also change. Symptoms of asthma may include:
* Wheezing, a whistling noise of varying loudness that occurs when the airways of the lungs (bronchial tubes Click here to see an illustration.) narrow.
* Coughing, which is the only symptom for some children.
* Chest tightness.
* Shortness of breath, which is rapid, shallow breathing or difficulty breathing.
* Sleep disturbance.
* Tiring quickly during exercise.
* Having a cold or another type of respiratory illness, especially one caused by a virus, such as influenza.
* Exercising (exercise-induced asthma), especially if the air is cold and dry.
* Exposure to triggers, such as cigarette smoke, air pollution, dust mites, or animal dander.
* Changes in hormones, such as during the start of a girl’s menstrual blood flow at puberty.
* Taking medicines, such as aspirin (aspirin-induced asthma) or nonsteroidal anti-inflammatory drugs.
Most asthma attacks result from a failure to successfully control asthma with medicines. By strictly following the doctor’s recommendations and taking all medicines correctly, it is possible in most cases to prevent these attacks from occurring. While some asthma attacks occur very suddenly, many get worse gradually over a period of several days.
Many children have symptoms that become worse at night (nocturnal asthma). In all people, lung function changes throughout the day and night. In children with asthma, this often is very noticeable, especially at night, and nighttime cough and shortness of breath occur frequently. In general, waking at night because of shortness of breath or cough indicates poorly controlled asthma.
Symptoms are also used along with peak expiratory flow to help define the green, yellow, and red zones of your child’s asthma action plan. You use this to decide on treatment during an asthma attack.
