- Exposure to cigarette smoke as a child, especially if your mother smoked during pregnancy.
- Birth weight below normal, which is less than two kilograms.

Factors triggering asthma attacks
There are several triggers asthma symptoms, but the triggers are different for each patient. If you already know what triggers your asthma, try to avoid it. Here are some asthma triggers:
- Allergens such as animal dander, dust mites, and pollen.
- Infection of the lungs and respiratory tract are commonly caused by the flu virus and fever.
- Drugs such as non-steroidal anti-inflammatory drugs (painkillers) such as aspirin and ibuprofen. For the record, aspirin should not be given to children under the age of 16 years.
- Airborne irritants such as chemical fumes, cigarette smoke, and air pollution.
- Weather factors, such as cold weather, windy weather, hot weather supported poor air quality, humid weather, and a drastic temperature changes.
- Food or drinks that contain sulfites (a natural substance that is sometimes used as a food preservative) such as butter, shrimp, processed foods, half-cooked food, fruit juice beverage packaging, and some particular wine that only fueled those who are vulnerable.
- Sport (sometimes asthma symptoms become worse when the sufferer exercise).
- Conditions in the room, as the rooms were damp or moldy, floorings, carpets chemicals, and dust mites.
- Emotional factors such as stress or laughter.
- Specific food allergies, also known as anaphylactic reactions. An example is people with asthma who are allergic to nuts. Anaphylactic reactions can trigger asthma attacks worse in sufferers.
Conditions when developing asthma sufferers
Once the symptoms of asthma (asthma attacks), usually the muscles around the airways tighten. Additionally there is increased inflammation (swelling) of the lining of the respiratory tract and increased sputum production are increasingly adding narrowing of the channel.
By narrowing the parts of the respiratory tract, then the air will be more difficult to flow so that the sufferer increasingly difficult to breathe. This condition is usually accompanied by the appearance of wheezing sound, although not all patients experience asthma. Even in life-threatening asthma attack once, it could be the sound of wheezing is not there.
Asthma attacks do not recognize the time and could happen at any time. But before that happens, there are usually warning signs a few days earlier. The warning signs include worsening symptoms (especially at night) and people who constantly have to use inhalers (inhaled medications for asthma) reliever.
