Asthma is a disease affecting the airways (bronchioles) that carry air to and from your lungs. From time to time the airways narrow (constrict) in people, who have asthma. The airways are tubes that carry air into and out of your lungs. People, who have asthma have inflamed airways. The inflammation makes the airways swollen and very sensitive. Cells in the airways might make more mucus than usual. Mucus is a sticky, thick liquid that can further narrow the airways. This causes the typical symptoms. The typical symptoms are wheeze, cough, chest tightness, and shortness of breath. Symptoms can range from mild to severe. Symptoms of Asthma are high at night and early in the morning when it’s cold.
Though Asthma is an incurable illness, even when you feel fine, you still have the disease and it can attack at any time. Good treatment and management helps a person to live a normal and active life. Although people of all ages suffer from the disease, it most often starts in childhood as children have smaller airways than adults, which makes asthma especially serious. When asthma symptoms become worse than usual, it is called an asthma attack. Asthma is treated with two kinds of therapies: quick-relief therapy to stop asthma symptoms and long-term control therapy to control symptoms. Though symptoms of Asthma in older people are same as the younger people, they sometimes get serious asthma attack. Severe symptoms can be fatal. It’s important to treat symptoms, when you first notice them. So, they don’t become severe.
Causes of Asthma :
Two main causes of Asthma are genetic and environmental factors
Family history is a risk factor for asthma, with many different genes being implicated. If a person has a parent with asthma, he or she is three to six times more likely to develop asthma than someone, who does not have a parent with asthma.
Many environmental factors have been associated with asthma’s development and exacerbation such as
- Tobacco smoke
- Airway hyperactivity
Many things can worsen asthma symptoms like aspirin or other nonsteroidal anti-inflammatory drugs and nonselective beta-blockers, sulfites in foods and drinks. Other health conditions can also make asthma harder to manage like runny nose, sinus infections, reflux disease, psychological stress, and sleep apnea. These conditions need treatment as part of an overall asthma care plan. By taking care of seasonal allergies one can reduce the severity of Asthma.
