What does wheezing indicate in a patient?

Wheezing is characterized by a high-pitched sound that occurs during breathing, specifically when exhaling. This sound is produced when air passes through narrowed airways, often due to inflammation, mucus, or bronchospasm. It is commonly associated with respiratory conditions such as asthma, bronchitis, or other forms of airway obstruction. The presence of wheezing indicates that there is something interfering with normal airflow, signaling a potential underlying issue that may require further evaluation or treatment. Understanding the nature of wheezing helps healthcare providers assess a patient's respiratory status and determine the appropriate course of action.
