However, if asthma is properly treated, there can also be long periods without symptoms or attacks.Ī number of different triggers can cause asthma symptoms or start an asthma attack: Your asthma does not stay the same, but changes over time, and every person with asthma has good days and bad days (or longer periods). The severity of the symptoms can differ in the same person at different times, and the effects of treatment can also vary. There are very big differences between people in how readily and how severely they react to different triggers. Some causes and triggers are common to all people with asthma, and some are more individual, especially allergens. This means that they react faster and more strongly to various triggers, such as allergens, viruses, dust, smoke and stress. When the airways have been inflamed for a long time, they become extra-sensitive. certain medications some people may be allergic to some drugs (e.g.food additives, such as tartrazine (an artificial food colouring), or food allergens, such as peanuts (sensitised or allergic individuals can have a very severe allergic reaction).smoking people with asthma and the parents of asthmatic children should avoid smoking. emotions, such as excitement, fear or anger.allergens, most commonly from house dust mites, pets or pollen.infections, usually those caused by a virus (e.g.The following triggers can cause asthma symptoms or start an asthma attack: These triggers can provoke attacks in individuals who already have a tendency to asthma, but they are not necessarily part of the cause of that tendency. Olympic athletes, famous leaders and celebrities, and ordinary people live successful and active lives with asthma.Īsthma triggers are factors that start asthma symptoms or an asthma attack by irritating the airways or worsening the inflammation in the airways. Regular controller treatment, particularly with inhaled corticosteroid (ICS)-containing medications, markedly reduces the frequency and severity of asthma symptoms and the risk of having a flare-up.Īsthma is a common condition, affecting all levels of society. When asthma is uncontrolled, or in some high-risk patients, these episodes are more frequent and more severe, and may be fatal.Ī stepwise approach to treatment takes into account the effectiveness of available medications, their safety, and their cost to the payer or patient. Some drugs can induce or trigger asthma, e.g., beta-blockers, and (in some patients) aspirin or other NSAIDs.Īsthma flare-ups (also called exacerbations or attacks) may occur, even in people taking asthma treatment. These responses are more likely when asthma is uncontrolled. Some variation in airflow can also occur in people without asthma, but it is greater in asthma.įactors that may trigger or worsen asthma symptoms include viral infections, domestic or occupational allergens (e.g., house dust mite, pollens, cockroach), tobacco smoke, exercise and stress. These symptoms are associated with variable expiratory airflow, i.e., difficulty breathing air out of the lungs due to bronchoconstriction (airway narrowing), airway wall thickening, and increased mucus. What is asthma? Asthma causes symptoms such as wheezing, shortness of breath, chest tightness, and cough that vary over time in their occurrence, frequency and intensity. Avoid serious asthma flare-ups (exacerbations, or attacks).Have normal or near normal lung function.Have productive, physically active lives.Avoid troublesome symptoms during day and night.When asthma is under good control, patients can: It causes respiratory symptoms, limitation of activity, and flare-ups (attacks) that sometimes require urgent health care and may be fatal.įortunately… asthma can be effectively treated and most patients can achieve good control of their asthma. Asthma is a common and potentially serious chronic disease that imposes a substantial burden on patients, their families and the community.
