Asthma is a disease that causes inflammation of your lungs and airways, causing difficulty in breathing. This results in asthma attacks. Even though there is no cure for asthma, you can control the symptoms and prevent future asthma complications. Not every individual with asthma will develop other health conditions or complications, but it is important to take proper precautions and manage the symptoms. Asthma and other health conditions are connected in a number of ways and can become life-threatening if left untreated.
