Many people think asthma only starts in childhood, but asthma in adults is common and can appear for the first time after age 20. This is known as adult onset asthma, and it may develop after respiratory infections, allergy exposure, workplace irritants, or lifestyle changes. Some adults had mild childhood asthma that returned later, while others experienced symptoms for the first time.
Recognizing the signs early is important for long-term respiratory health. Persistent coughing, wheezing, chest tightness, and shortness of breath should not be ignored. With proper treatment, trigger control, and a clear asthma action plan, many adults can manage symptoms effectively and stay active.
