If you have been diagnosed with asthma, it is important for you to know about the most common triggers of asthma. Asthma is a medical condition, which is characterised by paroxysmal wheezing respiration dyspnoea. It causes breathing difficulties, tightened chest and coughing. By identifying and reducing your exposure to several asthma triggers, you will be able to manage or control your asthma symptoms and the frequency of your asthma attacks. Here are the most common triggers of asthma you should know about:
Allergies that trigger asthma
Allergies are common problems and over 80% of people are suffering from asthma and are allergic, towards substances like weed pollens, animal dander, dust mites, mould and cockroach particles. Children having large amounts of cockroach droppings in their homes are more likely to develop childhood asthma. Dust exposure may lead to dust mite allergy in asthmatic patients.
Food which triggers asthma
Certain food allergies may lead to isolated asthma, where other symptoms are absent. Patients with food allergies can exhibit asthma as a part of anaphylaxis, which is food-induced. The common food items which are associated with allergies include eggs, peanuts, cow milk, soy, fish, wheat, shrimps, salads and fresh fruits. Several food preservatives also trigger asthma. They may include sulfite additives such as potassium bisulfite, potassium metabisulfite, sodium sulfite, sodium bisulfate and many others. These are commonly used in food processing and trigger asthma in sensitive people.
Asthma induced by exercise
Strenuous exercise may lead to the narrowing of the airways in maximum people having asthma. Exercise acts as a primary trigger for asthma symptoms in many people. Patients having exercise induced asthma are likely to feel chest tightness accompanied by coughing and breathing difficulties after completing an aerobic workout session. Although the symptoms subside, they may reoccur within some hours. You should warm up properly and slowly before a rigorous workout session to prevent an asthma attack.
