A new research has suggested that nasal congestion can be a sign of severe asthma.

This means that healthcare professionals should be additional vigilant when it comes to nasal complaints.

Furthermore, more severe asthma appears to be more regular than previously thought, reveals a study from the Sahlgrenska Academy's Krefting Research Centre.

The population research included 30,000 randomly selected participants from the west of Sweden and asked questions about different aspects of health.
