The causes of asthma attacks are known as triggers and generally include dust, fur, pollen, smoke and fumes. When they come into contact with the lungs the small tubes that make up your airways become inflamed and irritated. The reason why some people suffer from asthma while others don’t is still an area of uncertainty, however it is understood that a mix of genetics and environmental factors can cause asthma to be more prominent. The symptoms of asthma are most commonly wheezing, shortness of breath, coughing, and the sensation of having a tight chest. Symptoms are often worsened during the night. If not treated then asthma can escalate and worsen with time.
