Other things you can do to reduce or prevent exercise-induced asthma

Avoid outdoors exercising on days when it’s cold or ice, and cold air is drier and cools and dries the lining of the airways, acting as a stimulus for the release of bronchoconstrictor activity of chemical mediators.

Try breathing through your nose because the nasal passages and humidify the air warmed, that this way is less stressful for the airways.

Before starting exercise, warm up with short bouts of exercise, as this can reduce asthma following a period of more intense and prolonged exercise. The explanation for this phenomenon is unclear, but two factors may play a role: 1) Short intervals of exercise can improve lung function. 2) While the warming itself does not cause asthma attacks, may reduce the ability of the cells of the airways to release chemical mediators that cause asthma symptoms.

Drugs “preventive” are very useful in asthma, reducing airway inflammation, which is the main mechanism by which asthma occurs. When used regularly, producing an overall improvement of asthma, which also includes attacks caused by exercise.

To be effective, these medicines must be used regularly and for long periods of time. Not effective single dose taken before exercise and, usually, may need a week or more before they get benefits. The main drugs in this group are:

Inhaled corticosteroids, such as beclomethasone (Becloforte), fluticasone (Flixotide) and budesonide (Pulmicort). Inhaled corticosteroids are currently the main treatment of bronchial asthma because of its effectiveness and safety.

The receptor antagonists of leukotrienes, such as zafirlukast (Accolate) or montelukast (Singulair). They come in tablets and their effectiveness is difficult to predict, but have proved useful in the control of exercise-induced asthma. Read the rest of this entry »

How can you use medication to prevent exercise-induced asthma?

There are two ways:

- Short-term protection.

- Long-term protection.

Short-term protection

This protection lasts about 3 or 4 hours when the medication is taken before exercise. Usually, this type of inhaler medication should be used only in cases of mild intermittent asthma, which is not used anti-inflammatory medication (preventive) medication is used only to relieve symptoms (bronchodilators), which also used less once a day. Drugs that can help for short-term protection, we have: Read the rest of this entry »

Can I do exercise if I suffer from exercise-induced asthma?

Definitely yes. There are many athletes who have exercise-induced asthma and there are many steps you can take to troubleshoot this problem:

Asthma drugs: Several anti-asthma medications, usually an inhaler such as salbutamol (Ventolin), terbutaline (Terbasmin), salmeterol (Serevent), formoterol (Oxis), cromolyn sodium, nedocromil (Tilade, etc.). That utilized before exercise-induced asthma avoid exercise. Read the rest of this entry »

Who gets asthma when exercise?

Almost all asthma patients who exercise, especially if they are not in treatment or this is insufficient.

A minority of patients with severe asthma suffer exercise-induced asthma despite the best treatment.

Children are particularly affected by this problem, because they are much more active than adults and do more exercise.

When conducting studies, 3% of school-age children has asthma triggered by exercise. These figures vary slightly depending on geographic location.

When studies are done on athletes, says up to 12-15% have or have had asthma with exercise.

20% of the athletes who participated in the 1996 Olympics said they have asthma with exercise. Read the rest of this entry »

No one knows the exact mechanism by which exercise triggers asthma attacks. It seems to be involved nerve endings that control muscles and glands of the airways and changes in the distribution of blood flow through the lungs.

One of the most accepted hypothesis is this: When we exercise, breathing becomes faster and deeper and this, in turn:

- Increases evaporation from the surface of the lining of the airways, causing an increase in the concentration of solutes in the cellular environments. This is known as increased osmotic load.

- The airways are rapidly cooled due to heat losses produced by evaporation. Read the rest of this entry »

Asthma attacks caused by exercise are found in almost all patients with asthma who exercise a certain intensity, especially if they have fallen (or removed) the asthma medication. This phenomenon is so typical, if not present, should be revised diagnosis of bronchial asthma. In some patients the only manifestation of disease.

Since most people exercise, these asthma attacks caused by exercise are a potential risk that should be taken into account. Fortunately, in most cases adequate control is achieved with medications and other therapeutic measures. Read the rest of this entry »
