What is a common sign of asthma?

Shortness of breath is a hallmark sign of asthma. This condition is characterized by inflammation and narrowing of the airways, which leads to difficulty in breathing. Asthma can cause episodes of wheezing, coughing, and chest tightness, all of which contribute to a feeling of shortness of breath during physical activity or even while at rest.

While chest pain, rapid heartbeat, and dizziness can occur in various medical conditions, they are not specifically indicative of asthma. Chest pain might arise from a variety of issues, including heart or lung problems. Rapid heartbeat can be associated with a number of situations, from anxiety to more serious cardiac conditions. Dizziness can stem from many causes, such as low blood pressure or dehydration. Therefore, shortness of breath remains the most direct and common symptom associated with asthma attacks or exacerbations.
