Some key points regarding asthma

• Asthma is a chronic disease that affects your airways, the tubes that carry air in and out of your lungs.
• In asthma, the inside walls of your airways are inflamed, or swollen. The inflammation makes them very sensitive, and they tend to react strongly to things that you are allergic to or find irritating. When they react, they get narrower and less air flows through to your lungs. This causes symptoms like wheezing, coughing, chest tightness, and trouble breathing, especially at night and in the early morning.
• Asthma cannot be cured, but most people with asthma can control it so that they have few and infrequent symptoms and can live normal, active lives.
• When your asthma symptoms become worse than usual, it is called an asthma episode or attack. In a severe asthma attack, the airways can close so much that not enough oxygen can get to your vital organs. People can die from severe asthma attacks.
• Taking care of your asthma is an important part of your life. Controlling it means working closely with your doctor to learn how to manage your condition, staying away from things that bother your airways and bring on asthma symptoms, taking medicines as directed by your doctor, and monitoring your asthma so you can respond quickly to signs of an attack. Ask your doctor for a written daily asthma self-management plan and an emergency action plan for asthma attacks, and make sure you understand and know how to use them.
• Researchers still do not know what causes asthma, although they do know that if other people in your family have asthma, you are more likely to develop it. Being exposed early in your life to things like tobacco smoke, infections, and some allergens may also increase your chances of developing asthma.
• Some of the more common things that bring on asthma symptoms include exercise, allergens, irritants, and viral infections.
• Common asthma symptoms include coughing, wheezing, chest tightness, shortness of breath, and faster or noisy breathing.
• Doctors find out whether you have asthma by looking at your family history of asthma and allergies, exploring the things that seem to cause your symptoms or make them worse, and giving you a test, called spirometry, that measures how much air you can blow out read more
