Air is supplied to the lungs for purification through narrow tubes. When these tubes get inflamed and narrowed, it leads to a chronic condition called asthma.
Asthma can be triggered by allergens (pollen, mold and fur), cold air and changes in weather, exercise, flu, and the common cold.
Asthma is primarily managed with medication and by avoiding triggers that bring on symptoms. Medication may include long-term control medicines that should be taken on a daily basis seasonally and short-acting bronchodilators that act as a rescue medication for immediate relief. Asthma medication is delivered through a metered-dose inhaler, dry powder inhaler or a nebulizer, which converts liquid medicine into a fine mist.
