The exercise-induced asthma is a condition in which a person has difficulty breathing or wheezing after vigorous aerobic exercise. It can also be induced by intense activity. Asthma is generally characterized by inflammation of the bronchi and lungs is triggered by many factors, such as pollution, smoke, dust, the presence of pollen, mold in the air and respiratory infections such as colds and influenza. It was also noticed that every person with asthma has different factors specific to the stimulus. Although many features of asthma provoked by exercise as other types of asthma, it is primarily caused by aerobic activities.

Causes

It was found that people who experience asthma attacks after exercising, they most sensitive passages in the air. The air passages are very sensitive to changes in temperature and humidity. Under normal circumstances, breathing through the nose of people, which contributes to the heat and humidity of the humidity and temperature of inhaled air to look like the air in the lungs. However, the exercise involves breathing through the mouth, with a normal nasal breathing. When breathing through the mouth, the air reaching the lungs is colder and less humid, which is responsible for triggering an asthma attack. Blood flow increased bronchial linings with airway inflammation. mucus secretion is also induced by such an attack, which blocks the airways and makes breathing more difficult.

The situation is exacerbated if a person is allergic asthma, in addition to exercise-induced asthma and if he / she is engaged in an atmosphere where allergens are present.

Symptoms

Common symptoms of exercise-induced asthma include shortness of breath, coughing, wheezing or increased rate. In addition to this, patients may also experience chest pain, extreme fatigue and chest tightness. Sometimes the membranes cyanosis or blue skin and mucous membranes may also occur as a result of reduced blood oxygenation. However, it has been found in people with allergic asthma and exercise-induced at a time.

Diagnosis and Treatment

correct diagnosis of this disease is very important for effective treatment. Usually, diagnosis begins with questions about the patient's symptoms and medical history. Depending on the severity and duration of symptoms, degree of airway obstruction and the effects of such attacks on the normal activities, attacks are classified as attacks with mild, moderate and severe. In addition, some tests are also conducted for the correct diagnosis of the disease. Spirometry is a test performed using a spirometer. A spirometer is a device that can measure the amount of air and speed that you can inhale and exhale. An oximetry test is to measure the amount of oxygen in the blood, test meter peak flow is conducted to assess the strength of the expiration during an attack.

The best way to prevent an asthma attack is to avoid factors that may worsen. However, people who want to continue their exercise programs and sports activities can take the help of drugs. Some common drugs are beta agonists, inhaled anti-inflammatory fog as corticosteroids or leukotriene antagonists, mast cell stabilizers. An asthma attack is usually characterized by a refractory period, the exercise or strenuous physical activity or produces only mild symptoms or not. Therefore, many people exercise program and sports activities in connection with such refractory period to prevent exercise-induced asthma.

To prevent exercise-induced asthma, many precautions must be taken. This includes appropriate medications and reduce the required amount of stimulating factors of the disease. However, before opting for a drug or some preventive measures, it is always advisable to consult a medical certificate.
