    Asthma : Symptoms ,Prevention And Possible Treatments

Wednesday, November 23,2016

Asthma is a disease characterized by a more or less important inflammation of the respiratory tract, bronchi , bronchioles . It results in difficulty breathing, shortness of breath, wheezing or tightness in the chest.

Asthma is a chronic disease most often manifested by seizures interspersed with periods when breathing is normal. In some people, however, asthma induces permanent respiratory discomfort interfering with daily activities.

Asthma is often linked to an abnormal airway reaction to various stimuli (allergens in the air, smoke, etc.).

The asthma crisis

The asthma attack corresponds to the sudden aggravation of the symptoms. In many people, asthma manifests itself in occasional seizures, breathing is normal outside crises.

An attack of asthma often begins with a dry cough, followed by difficulty breathing, which causes a clearly audible wheeze. It is usually accompanied by expectorations of mucus (cough and sputum).

During a crisis, the opening of the bronchi is reduced due to a significant inflammatory reaction and contraction of the muscles of the bronchial wall.

Seizures can be effectively quenched by drugs. However, they are potentially dangerous, especially in frail people (elderly, suffering from a respiratory infection, etc.).

Prevalence

Since the 1960s, asthma has been increasing steadily in industrialized countries, where it is estimated that between 5% and 10% of the French population, about 5 million people suffer from asthma to varying degrees (6, 7% in 2009). Women appear slightly more affected than men (9.4% vs. 6.7%).

Two periods of life seem more conducive to the onset of asthma: childhood and early forties.

One in eight children (8-12% of children aged 11 and under) have asthma symptoms. This is the first chronic illness of the child. Fortunately, about half of these children will become completely asymptomatic during adolescence. They will still be at risk.

Causes

The causes of asthma are not well known, although it is known that there are both genetic and environmental risk factors.

Inflammation of the airways results in the production of thick mucus inside the bronchi, which interferes with air circulation. At the same time, the muscles around the bronchi contract, resulting in the “closure” of the bronchi (bronchospasm). This is what causes respiratory discomfort.

Asthma is associated with respiratory allergies in about 80% of cases, but it is not always of allergic origin. In people with asthma, excessive bronchial sensitivity (hyperreactivity) is associated with one or more substances.

The following factors may help trigger an asthma attack or aggravate respiratory discomfort, but they are not the cause of asthma.

Airborne allergens (dust, pollen, animal hair, dust mites).
Aerial pollutants (irritants in the workplace, wood smoke, exhaust, air pollution, etc.).
Tobacco smoke.
Food (food allergies) or food additives, such as sulphites.
Some drugs (aspirin and other non-steroidal anti-inflammatory drugs, beta-blockers).
Infections in the respiratory tract (colds, bronchitis, sinusitis, etc.), as they cause local inflammation.
Exercise, especially if practiced outside in winter, in cold and dry weather.
Strong emotions (laughter, tears, anger, excitement), especially in children.

Severity

In some people, asthma attacks are rare and do not have a serious impact on everyday life. However, asthma can become more severe when seizures are frequent and symptoms, intense. In some cases, breathing difficulties and shortness of breath persist even between seizures.

Here are some signs of severe or poorly controlled asthma:

Symptoms at night;
Limitation of activities during the day;
The need to use inhalers several times a day or overnight;
Crises that require hospitalization.

Complications

Poorly controlled asthma can cause permanent symptoms. Exceptionally, it can be complicated with a respiratory distress and endanger the lives of the people who suffer from it. Each year in France, approximately 500 adults die as a result of an asthma attack. Most of these deaths could be prevented by good disease management.

Thus, the vast majority of people with asthma can live quite normally, provided they follow their treatment well. Moreover, it is rare for crises to occur suddenly without a harbinger. Learning to recognize these signs helps to act in time to reduce the severity of crises.

Symptoms of Asthma

Symptoms may be intermittent or persistent. They can appear after physical exercise or in the presence of another trigger, and they are usually more pronounced at night and early in the morning.

Difficulty breathing or shortness of breath (dyspnea)
Wheezing
A feeling of tightness, chest tightness
A dry cough
Note. For some people, asthma only results in a persistent cough that often appears at bedtime or after physical exertion.

Warning signs in the event of a crisis

In the event of an asthma attack, the symptoms of shortness of breath, cough and sputum become worse. If, in addition, the following symptoms are present, it is imperative to call the rescue or to go to the emergency, in order to control the crisis as soon as possible:

Sweating;
Increased heart rate;
Difficulty speaking or coughing;
Great anxiety, confusion and agitation (especially in children);
A bluish coloring of the fingers or the lips;
Disturbances of consciousness (somnolence);
Crisis medication, usually effective, does not seem to work.

People at risk for asthma

People with a genetic predisposition to allergies or having parents or asthmatic siblings.
Persons of low birth weight.
Obese people.
People with gastroesophageal reflux disease. Although reflux is not a cause of asthma, it is considered a factor of aggravation, or even a trigger factor for asthma symptoms.

Risk factors

The increase in the number of asthmatics in recent decades may be attributable to the following external factors:

People who are frequently exposed to chemicals, such as paint, hair products, metals, plastics, etc., in their workplace.
Pollution. More and more people live in the heart of urban areas, where air pollution is high.
Exposure to tobacco smoke. Smoking in the mother during pregnancy also increases the risk of asthma in children.
Active and passive smoking irritates the respiratory tract and aggravates asthma.

Asthma Prevention And Possible Treatments

Can we prevent it?

The treatments are intended to eliminate the symptoms of asthma, but in some people, asthma remains a chronic disease with periods alternating improvement and aggravation. Sometimes, asthma disappears after adolescence, especially if it has been treated properly in childhood and if there is no allergic ground.

At present, the only recognized preventive measure is to avoid active and passive smoking. Tobacco smoke irritates the airways, creating a breeding ground for respiratory diseases. There is currently no known measure to prevent asthma; There is no medical consensus in this regard.

Eating fiber contained in fruits and vegetables in good quantity could help prevent asthma.

The development of asthma would depend on the amount of fruits and vegetables consumed. Intestinal bacteria ferment dietary fiber in the digestive tract from fruits and vegetables. This helps transport fatty acids in the blood that influence the immune response of the lungs. This is demonstrated in mice who would have on this type of reaction, the same functioning as humans …

Breastfeeding also provides some protection against asthma. It appears to be related to allergenic products which, when consumed by the mother during breastfeeding, pass into milk, resulting in a tolerance to these allergenic substances.

Various avenues of prevention are explored with regard to asthma caused by allergies. To know them, consult our Allergies card.

Early detection measures

It is possible to detect asthma at the beginning of its appearance through spirometry tests. These are measurements of the capacity of the lungs (e.g volumes and air flows in the lungs at inhalation and exhalation), using a spirometer.

For the patient, it is enough to blow in a small electronic device equipped with a tip. Spirometry has been used for several years in the diagnosis of asthma and chronic obstructive pulmonary disease (COPD). This examination is carried out by prescription of the attending physician, a pulmonologist or a hospital.

The treatment of asthma

Asthma is often a chronic condition that requires regular treatment, even between seizures. Medications to control asthma do not provide permanent healing. They facilitate breathing by increasing the opening of the bronchi (bronchodilation) and reducing inflammation. Most of them are taken by inhalation, allowing them to act quickly, with as few adverse effects as possible. The doctor also tries to give the smallest dose of drugs for symptom control with the best tolerance of the treatment.

Yet, despite the effectiveness of treatments, 6 out of 10 asthmatic people fail to control their symptoms. The main causes are poor understanding of the disease, fear of side effects and forgetting of drugs. However, the side effects of inhalation treatments are minimal compared to the risks associated with severe and frequent asthma attacks

Inhalation technique. The use of inhalers seems simple, but it requires a certain technique to be effective. Less than half of asthmatics use their inhaler correctly.

The different inhalers (metered dose inhalers, dry powder inhalers and nebulizers) each have a particular mode of use. The doctor and the pharmacist can explain the right actions.

Aerosol dispensers. Shake the aerosol well and hold it vertically. After gently emptying the lungs, inhale slowly and deeply through the mouth, triggering the spray during the first second of inspiration. It is then necessary to hold its breath for 5 to 10 seconds, then exhale slowly.

Dry powder inhalers (eg Turbuhaler®). These systems are easier to use because they do not require coordinating inspiration and triggering. Inspire as hard and fast as possible, block your breathing for 10 seconds and exhale outside the inhaler.

Inhalation rooms. They are used with a metered dose inhaler in children under 8 years old and the elderly. In young children, inhalation is done with a face mask, which must be kept on the face for at least 6 calm breaths.

The asthmatic person is increasingly involved in the monitoring of his respiratory condition. For example, people with severe asthma can measure their peak flow in order to adjust their treatment according to the results. Training must have been followed beforehand.

Medications

There are 2 categories of medications to control the symptoms of asthma. The first, called crisis or relief medicines, must be taken in case of symptoms. They have an immediate relief action, but do not allow to calm the bronchial inflammation.

The other drugs constitute the control or background treatment. They should be taken every day, even in the absence of respiratory discomfort as soon as asthma is moderate and persistent. They reduce the inflammation of the bronchi and spacing the seizures. If they are not taken regularly, the frequency and severity of seizures increase, as well as the need for emergency medication.

Many people with asthma do not fully understand the difference between crisis treatment and control treatment. Make sure you understand what each of your medications is for and how often you should use them.
