Respiratory disorders due to constriction of the airway
The mechanism of onset of shortness of breath due to asthma
Asthma is accompanied by a narrowing of the Airways large and small. The restrictions caused by:
- the contraction of the muscles around the Airways;
- swelling while on the mucous membrane on the inside of the Airways;
- edema can develop on the inside.
Because narrowing it, inhaled and exhaled air can be more difficult to pass. This causes the sound of wheezing.
The respiratory tract is inflamed
On asthma, respiratory tract constantly inflamed. As a result, they are hyper-reactive: they are often volatile as a result of an allergic reaction to certain stimuli, such as dust mites or certain foods. Also physical activity, cigarette smoke, infection and irritation in the workplace can stimulate the inflamed airways.
What are the consequences of asthma?
It's hard to breathe
As a result of constricting, an asthmatic having difficulty breathing and wheezing sound, often have to cough and he felt anxious. The patient is usually free of symptoms or complaints during the attack. In addition, treatment-treatment can greatly reduce the number of attacks. However, for many patients have asthma means major limitations in daily life. The severity of asthma varies from person to person. In addition, asthma can vary with the same person over time.
Asthma on the rise
The frequency of asthma has increased significantly in recent years. This increase is partly due to a lifestyle change. For example, a theory of the demonstrate that we grow up in environments that are too sterile. Quite contaminated with bacteria will increase the risk of allergies and asthma. On the other hand, research shows that asthma is more common in the city. There, an increase of asthma can be caused by exposure to excessive air pollution.
Asthma is a disease that is similar to COPD
Asthma is almost similar to COPD, which stands for ' Chronic Obstructive Pulmonary Disease or chronic obstructive pulmonary disease. Like asthma, breathing is made more difficult in COPD. Nevertheless, there are a number of differences.
The difference in asthma and COPD
In COPD narrowing Airways gradually, it cannot be changed and is usually caused by smoking. In addition, Usually developing COPD in elderly, rarely occurs at the age of 45 years. COPD also have nothing to do with allergies.
In asthma, the symptoms vary from time to time and the disease primarily occurs through successive attacks. Often the cause of allergies, and asthma also attacked the children.
Symptoms of asthma
Symptoms of shortness of breath during the night and morning: cough and shortness due to asthma
An asthmatic patient must put extra strength to get the same amount of air through the air duct narrowness. His chest felt tight, neck muscles contract, the talk sometimes becomes difficult. Patients may also be anxious.
Asthma sufferers often experience cough and shortness. Batuknya worsens at night or in the morning. They cough up mucus from their Airways to prevent constriction. Dry cough and often quite painful.
Exhaustion: heavy and short breath
Shortness of breath and coughing can cause insomnia and daytime fatigue. Patient fatigue due to sleep deprivation. A limited oxygen supply makes it difficult to sustain physical effort.
Such as whether asthma attacks?
Sudden asthma symptoms get worse
Asthma attacks are the symptoms suddenly deteriorated. Patients have to cough up more weight, he's feeling more anxious, start wheezing, pain in the chest area, etc.
Gedjala asthma differs from patient to patient
Asthma attacks vary from person to person and from situation to situation. All or only some of the symptoms can occur, or symptoms vary according to time or the environment.
In the case of a severe asthma attack, the patient's life may be endangered by lack of oxygen. If the patient remains shortness of breath even after using the medicine, emergency services should be informed so that the patient receives the right medication (cortisone, adrenaline, etc.).
Asthma causes: what causes shortness of breath?
Genetic factors
Asthma has a component of offspring, but the relationship is not direct. Asthma prominently is more common in some families. But not every child from parents of asthmatics also automatically gets asthma. The estimates assume a 20 to 50% if one of the parents suffer from asthma, 40 to 75% if both parents have the disease. A predisposing offspring descended, but additional environmental factors also determine whether the condition can happen or not.
Gender
Until the age of 14 asthma occurs twice as often in boys as in girls. Then the difference is becoming smaller. In adults, asthma is even more common in women than in men. The reason of this difference between men and women is unclear.
Asthma as an allergic reaction
In 50% of cases, asthma attacks may be a allergic reaction. In children, the proportion is even greater: 90 to 95%. In these patients, asthma often is one of the symptoms of allergic symptoms, such as skin (eczema), fever, food intolerance, etc. Allergens that trigger allergic reactions can come into contact with the body via food or breathing.
Food allergy
Certain food allergies can trigger asthma attacks. The common is eggs, cow's milk, soy milk, flour, fish, shrimp, and more. Asthma patients can also be allergic to certain food additives.
