Asthma is a chronic lung condition that affects millions of people worldwide. It is a long-term, inflammatory disorder of the airways that can cause breathing difficulties, coughing, wheezing and chest tightness. People with asthma have difficulty breathing, and it can become worse with physical activity or exposure to certain environmental triggers. Although the exact cause of asthma is not known, there are certain risk factors that can increase a person's likelihood of developing the condition.
Genetic Factors
Asthma can be passed down through families, often referred to as a “genetic predisposition.” If a person’s parents or siblings have asthma, they are more likely to develop the condition. It is thought that genetic factors play a role in determining how sensitive a person’s airways are to certain triggers.
Environmental Factors
Exposure to certain environmental triggers can increase a person’s risk for developing asthma. These triggers include air pollutants, chemicals, smoke, animal dander, dust mites, mold, pollen, and other irritants. People who are exposed to these triggers on a regular basis may be more likely to develop asthma.
Other Factors
Other factors that may increase a person’s risk for developing asthma include pre-existing health conditions such as allergies, chronic respiratory infections, obesity, and exposure to certain viral infections during childhood.
Asthma is a complex condition that can be caused by a variety of different factors. It is important to speak with a healthcare provider to determine the best treatment plan for your individual needs.
