J40-J47: Chronic lower respiratory diseases
J45: Asthma
Asthma is a group of conditions that cause inflammation and narrowing of the bronchial tubes, the passageways that allow air to enter and leave the lungs. This can lead to episodes of wheezing, tightness in the chest, shortness of breath, and coughing. The exact cause of this group of conditions is unknown, but triggers often include allergens, pollution, cold air, exercise, infections, and stress. Asthma can occur at any age but most often begins in childhood. Disease progression varies greatly from person to person; for some, it remains a minor annoyance while for others, it can significantly interfere with daily life and might lead to a life-threatening attack. Asthma involves the respiratory system, affecting your ability to breathe properly. It’s chronic in nature, meaning it tends to persist long-term. Symptoms can flare up from time to time and then disappear.
