Asthma is a lung disease that inflames and narrows your airways. Normally as you inhale, air moves freely through your trachea or windpipe, then through large tubes called bronchi, smaller tubes called bronchioles and finally into tiny sacs called alveoli.
Small blood vessels called capillaries surround your alveoli. Oxygen from the air you breathe passes into your capillaries. Then carbon dioxide from your body passes out of your capillaries into your alveoli so that your lungs can get rid of it when you exhale.
Your bronchioles expand when the air is warm moist and free of irritants and allergy causing substances called allergens. When air is cold or dry or contains irritants or allergens your bronchioles contract.
If you have asthma, your airways are frequently inflamed and swollen. Certain substances can cause your inflamed airways to over react even more, resulting in an asthma attack.Triggers of asthma attacks are slightly different for everyone but usually include:
The symptoms of an asthma attack include coughing, wheezing, shortness of breath, and tightness in your chest. During an asthma attack also known as a bronchospasm, the muscles around your airways tighten and the airway wall becomes more swollen. Your airways also produce thick mucus that narrows them even more, making it hard for you to breathe. If you have asthma, your doctor may prescribe medications to reduce:
During an asthma attack, you may need to use a short-acting rescue medication called a bronchodilator. This medication causes your airway muscles to relax quickly and provide symptom relief within minutes.
