Asthma-COPD Overlap Syndrome (ACOS)

Asthma-COPD Overlap Syndrome (ACOS) is a condition where a person has features of both asthma and chronic obstructive pulmonary disease (COPD). Asthma is a disease characterized by wheezing, shortness of breath, and chest tightness due to airway inflammation, while COPD involves long-term airway obstruction usually from smoking. People with ACOS experience symptoms of both conditions, such as ongoing breathing difficulties and a higher response to certain medications. This overlap can make diagnosis and treatment more complex, requiring tailored approaches to manage symptoms effectively and improve quality of life.
