Asthma is a chronic inflammatory disease of the respiratory system. Asthma is a hyper-responsiveness (overly strong response) associated with the airways of the lungs and can lead to recurrent episodes of wheezing, breathlessness, chest tightness, and coughing particularly at night or in the early morning.
Small tube like structures called bronchioles make up the airways in the lungs. They connect to larger tubes (bronchi and trachea) that carry air to and from the lungs and nose when we breathe. In a non-asthmatic person, the muscles around the airway tubes are relaxed and the tissues are thin, allowing for easy air flow. In an asthmatic person the muscles around these same airways contract (tighten and thicken) and the airways become inflamed and lined with excessive mucous. These two conditions restrict the free flow of air,making it difficult for air to breathe. In a severe asthma attack, the airways can close so much so that vital organs do not get enough oxygen, this may lead to death.
Research has not been able to definitively prove why some people get asthma and others do not.
Two broad classes of factors have been shown to influence the risk of asthma, however.
i) those that cause the development of asthma (causal) such as genetics, obesity, gender.
ii) those that trigger an asthma attack (environmental) such as allergens,infections, tobacco smoke, outdoor/indoor pollution, diet.
