What Are Some Causes of Wheezing and Coughing?

Some causes of wheezing and coughing include allergies, asthma, bronchitis, emphysema, heart failure, pneumonia, smoking and anaphylaxis, states Mayo Clinic. Other possible causes include lung cancer, inhaling a foreign object, sleep apnea and respiratory syncytial virus. Wheezing and coughing are the primary symptoms of bronchitis, while asthma is the main cause of recurrent wheezing.

Wheezing and coughing are symptoms of different health conditions, so it is important to seek medical attention to pinpoint the exact condition, explains the Palo Alto Medical Foundation. Wheezing is a whistling sound that occurs while breathing and sometimes it can be accompanied with difficulty breathing. It occurs due to narrowing of the airways, which occurs because of inflammation from a particular condition.

To determine the cause of wheezing and coughing, the doctor asks a patient questions about the symptoms and the possible factors that triggered them, says WebMD. The doctor uses a stethoscope to listen to the lungs to determine the location of the wheezing and its severity. Patients undergoing the diagnosis for the very first time may undergo a breathing test called spirometry and even a chest X-ray. Treatment of wheezing and coughing depends on the underlying condition. The main aim of treatment is to reduce inflammation and to open the airways.
