Asthma is a chronic inflammatory disorder of asthma. In a asthma patient many factors can trigger asthma exacerbation. Common triggers of asthma are stress, cold exposure, any food to which the patient is allergic, lung infection to atypical organism and exposure to any noxious smoke etc. Now, stress or cold or food allergen usually trigger asthma exacerbation within minutes. Lung infection takes 2-3 days to trigger asthma. We usually advise our asthma patients to monitor his/her peak flow so he /she can predict when asthma getting uncontrolled and seek doctors advice. When asthma exacerbation is due to any food or cold exposure immediate seek doctors advice.

Many reactions will start to manifest the symptoms within 30 minutes, but not all reactions will manifest symptoms within 30 minutes, meaning that it is very possible to have a nearly immediate reaction (within 3-5 minutes), but sometimes a reaction will take very long to manifest. This is why people, who get allergy injection therapy, where the body is being directly exposed to an asthma trigger, must wait at least 20 minutes in the office just in case a reaction manifests. If the trigger is a food allergy, the possible reaction time range can be larger (like seconds all the way up to hours) since, for some people the food must be digested before they have an reaction and for some people, the slightest exposure to the food can cause a rapid, and deadly reaction called Anaphylaxis.
