Asthma can be controlled but not cured completely. Asthma is incurable because it is a sudden allergic response to triggers that ranges from environment to genes.
The human immune system works to fight against toxic allergens to keep us safe from falling ill. However, the immune system becomes sensitive in case of people with asthma that reacts to unnecessary foreign particles to induce a response. The researchers are still unable to understand the reason behind a body considering harmless substances as allergen to induce an asthma attack.
The immune system of people with asthma sees every foreign particle as a threat and releases chemicals in the blood to prepare a defence mechanism. But the problem is that the immune system of people with asthma initiates a defence response for even the harmless particles and frequently. The frequent symptoms of defence response such as breathlessness, wheezing and coughing inflames and irritates the airway. In severe conditions, an irritated airway fills with mucus that makes it difficult to breathe.
Moreover, asthma can be controlled by understanding the triggers and avoiding them completely. In most cases, asthma can be controlled with bronchodilators that are used in the form of an inhaler.
