Asthma is a respiratory disease that occurs due to the tightening of the lungs. It can develop at any age and is common amongst children. Asthma attack occurs when your lungs do not get sufficient air to breathe. Asthma could be hereditary meaning that if a parent has asthma then chances is that the child may develop asthma as well.

Symptoms of Asthma
Difficulty in breathing, coughing, pain, and-or tightness in the chest and wheezing are common asthma symptoms. Children may also suffer from hay fever.

Reason for Asthma Attack
The two reasons that can provoke an asthma attack are:

- Triggers They cause tightening of airways and result in bronchoconstriction. Asthma triggers include mould, smoke, dust, air pollution, respiratory infections, and foods. If airway inflammation were already present then it would react quickly to triggers and can cause asthma attack. Triggers symptoms do not last for long and are reversible.
- Causes or Inducers They cause airway inflammation and hyper responsiveness. The inducer symptoms last for long and are not easily reversible in comparison to trigger symptoms. Allergens and respiratory viral infections are common inducers.
- Allergens: the common cause of inflammation is inhaled allergens that include pollen, moulds, and animal secretion and dust mites. When exposed to allergens may cause immediate symptoms like coughing as the airways tighten due to sensitivity. You can get relief from these symptoms through bronchodilator. However, late response occurs due to inflammation, which is difficult for the physician to identify asthma's actual cause.
- Respiratory infections: this is the common cause of asthma. In some cases, influenza vaccine is helpful in preventing respiratory problems that tend to occur due to influenza.

How to Prevent Asthma Attack
Prevention is better than cure. You should consult your doctor if you have doubt that you are suffering from asthma. Try to develop a plan to prevent asthma with the help of your doctor. The action plan may help in controlling asthma. Try to avoid things that may trigger an asthma attack.

Medications
You should take medications as recommended by physician on regular basis. You can get relief from asthma attack by using inhalers or over the counter decongestant sprays. Yoga or regular exercise also gives relief from asthma.

Proper intake of medications and practicing action plan helps to control your attack. Asthma is serious so you need to control it with proper medication.
