Understanding Wheezing
Wheezing refers to the subtle whistling or rattling noise that occurs during the process of breathing, particularly when exhaling. It occurs when the air passages in the lungs become narrowed as a result of inflammation in the bronchial tubes. This narrowing increases the pressure on the air entering and leaving the lungs, resulting in the distinctive wheezing sound. Individuals with chronic bronchitis are more likely to experience wheezing, which tends to worsen after engaging in activities that require physical exertion, such as climbing stairs or running.
Nasal Congestion or Excessive Nasal Discharge
One of the initial signs of bronchitis is nasal congestion or excessive nasal discharge. The virus or bacteria that causes bronchitis typically begins by infecting the nasal passage. From there, it progresses to the mucous membranes of the lungs. This progression explains why nasal symptoms, such as blockage or a runny nose, are among the earliest indications of bronchitis. These symptoms are especially common in children, as their immune systems are still developing and are therefore more susceptible to infections.
