Which symptom could indicate worsening asthma control in patients?

Increased frequency of night awakenings is a significant symptom that could indicate worsening asthma control in patients. Nocturnal symptoms in asthma, such as waking up at night with coughing, wheezing, or shortness of breath, often signify that the condition is not well-managed and may be exacerbating. Asthma is known to affect patients more during the night, and frequent night awakenings could indicate that the airways are becoming more inflamed or reactive, which compromises overall control of the disease.

When patients experience more night awakenings, it can reflect poor asthma management, inadequate medication adherence, or an increase in exposure to triggers. Monitoring and addressing these symptoms can help in adjusting treatment plans to improve overall asthma control and reduce the frequency of exacerbations.

In contrast, the availability of a rescue inhaler typically serves as a preventive measure against acute symptoms rather than an indicator of asthma control. Consistent peak flow readings usually suggest stable lung function, while regular activity without breathlessness is a positive sign of good control, indicating that the asthma is well-managed. Therefore, the frequency of night awakenings stands out as a crucial marker for assessing worsening asthma control.
