Asthma-COPD Overlap Syndrome

Asthma-COPD Overlap Syndrome (ACOS) describes a condition where a person has features of both asthma and chronic obstructive pulmonary disease (COPD). It involves persistent airflow limitation, with asthma-related airway inflammation and variability, alongside COPD’s progressive lung damage. People with ACOS often experience symptoms like coughing, shortness of breath, and wheezing, and may find their condition more challenging to control than either disease alone. Recognizing ACOS helps healthcare providers tailor treatment strategies to effectively manage symptoms and improve quality of life.
