How to prevent asthma attacks. Learn in detail about types of asthma, symptoms and signs of asthma attack and preventing and treatment of asthma.
Asthma is a chronic lung disease that causes inflammation and narrowing of airways thus making breathing difficult.
Asthmatic attacks may be as a result of allergic reactions or genetic disorders and has far reaching consequences if not treated and managed properly.
Since Asthma is a long term disease, its prevention is critical and this discussion will help you understand how it can be prevented, treated and managed.
Types of Asthma and Their Causes
The following are the most common types suffered by majority of people all over the world.
Pollen, pet dander, mold, dust mites and roaches are some of the airborne substances that can worsen asthma symptoms by triggering flare ups.When they get into contact with your immune system, a substance called immunoglobulin is released.
Too much of this substance is dangerous as it is likely to cause swelling and narrowing of the lung airways resulting into breathing difficulties. This may in turn trigger an attack.

Exercise Induced Asthma
It is triggered by strenuous exercise that narrows lung airways. During and after the exercise, you may experience shortness of breath, coughing and wheezing.
This is because as you exercise, you inhale either cold or dry air which reacts with linings of the lung and cause airflow obstruction due to the inflammation of the airways.
With proper management of asthma, exercise is still possible without being exposed to the symptoms.
Exposure to certain chemicals, smoke or dusts in a work place can induce asthma. The symptoms tends to worsen during working days but may be less serious during off days. When inhaled, they cause irritation which in turn leads to an asthma attack.
According to American Academy of Allergy Asthma and Immunology, it is the most common of lung- related diseases in developed countries, with United States having about 15% of reported cases.
Nocturnal (Nighttime) Asthma
Nocturnal asthma has higher chances of occurring at night thus reduces the quality of sleep. Sometimes, its symptoms may not be detected during the day but during the night, between 2 and 4 a.m you may experience short breath or nocturnal wheezing.
The major causes are not yet known but most studies show that possible causes may include; being in a reclining position, cooling of the airways and changes in bronchial function as as a result of sleep.
Also known as chronic cough, this type of asthma is characterized by dry, non productive cough and is common in young kids.
Its persistence may lead to development of classic asthma, whose symptoms are wheezing and shortness of breath. It can occur during the day or at night and lasts between six to eight weeks, or more.
Studies show that most incidences are reported with people living in the northern part of United States who have less exposure to sun and vitamin D levels.

According to National Heart, Lung and Blood Institute, the following are some of the drugs recommended for long term management of chronic asthma:
- Cromolyn. Is taken using a device called nebulizer and goes directly into the lungs. It helps in preventing inflammation of airways.
- Omalizumab. This is an anti-allergy medicine and is administered as an injection once or twice a month. It prevents the body from reacting to allergens such as dust mites.
- Inhaled Corticosteroids. These are the most effective and preferred medicine for asthma management. They help reduce inflammation and swelling which makes airways sensitive to inhaled substances.

Mayo clinic recommends the following drugs for quick relief during the attack or before exercise:
- Short-acting beta agonists. They are taken using either inhaler or nebulizer and help ease symptoms during attack. They include albuterol (ProAir HFA, Ventolin HFA) and levalbuterol (Xopenex).
- Ipratropium . The medicine acts quickly and immediately relaxes your airways. It is mostly used for chronic bronchitis but is of more help during asthma attacks.
- Oral and intravenous corticosteroids. They relieve airway inflammation which results from severe asthma. When used for a long time they may have side effects hence recommended for short term use only.
This treatment is for severe asthma that does not respond to corticosteroids or other long term medications. It works by heating the airways in the lungs, smoothing inside airways muscles thus making breathing easier hence reduces possibility of attacks.
Going for regular check ups as may be recommended by your doctor helps him decide whether you should continue with the same medication or if there is need of change.
Whenever you visit your doctor, you should be very open on your condition and answer his questions correctly as this will make him assess your situation and make proper decisions.
