Asthma is a chronic inflammatory disorder of the airways. The causes of asthma attacks can be different for different people. One thing remains unchanged: when airway contact with asthma triggers, they become inflamed, narrowed and filled with mucus.
During an asthmatic spasm, smooth muscle, inflammation and swelling of the airway mucosa, intense secretion of mucus lead to narrowing of the airways. This increases the sensitivity of the bronchi and leads shortness of breath, cough, or whistling sound during breathing. Cough can be caused by irritation of the bronchi and the desire of the body to get rid of the accumulated mucus.
Why do you get asthma?
Allergy plays a large role in causing asthma in many people. Allergy and asthma often go hand in hand. Eighty percent of people with asthma suffer from allergic components present in the air: pollen, plants, trees, grasses, molds, animal dander, house dust, insect remains. At home, the irritants may be met in odors detergents or home pests agents.
If you have a predisposition to asthma, it is important to understand what factors may provoke it. Understanding triggering factor (triggers) of your disease, you will be able to control it, avoiding contact with these factors and reducing the frequency of attacks. For example, if you find that allergens cause asthma attacks, that means you have an allergic asthma and you will have to “hide” from allergens.
Food and food additives which trigger asthma
Although food allergens rarely cause asthma, they can trigger severe life-threatening condition. The most common foods associated with allergic reaction are the following:
- cow’s milk;
- shrimp and other shellfish;
- salad and fresh fruits
Food cans are also able to trigger asthma. Sulfite agents such as sodium sulfite, potassium sulfite, sodium pyrosulfite, potassium pyrosulfite, sodium sulfite are often used in the cooking of food cans and can cause asthma in humans who has predisposition to the disease.
Intense exercise can result in a narrowing of the airways to 80% in people with asthma. Sometimes exercise can be a major cause of asthma symptoms. In case of exercise induced asthma the following symptoms occur:
- Chest tightness;
- shortness of breath in the first 5-8 minutes of aerobic exercise.
Usually these symptoms disappear within 20-30 minutes of training, but often the next attack occurs in 6-10 hours.
Asthma and Heartburn
Asthma and heartburn often go hand in hand. Recent studies have shown that approximately 89% of asthma patients also suffer from heartburn, known as gastroesophageal reflux. Gastroesophageal reflux occurs more often at night when the person is in the supine position. Normally, the valve between the esophagus and the stomach prevents reverse release of stomach acid into the esophagus. In case of gastroesophageal reflux, the valve function is impaired. There follows the reverse release of stomach acid into the esophagus; if the acid enters the throat or respiratory tract, it leads to an asthma attack.
Reflux is one of the most common causes of asthma in adulthood, with no prior allergies history or tendency to bronchitis, hereditary predisposition, uncontrolled asthma or cough in the supine position.
Smoking and Asthma
Smokers have more serious predisposition to asthma.
- If an asthmatic smokes, he can worsen symptoms, such as cough or shortness of breath;
- Women who smoke during pregnancy increase the risk of wheezing while breathing in their children;
- Children whose mothers smoked during pregnancy, had poorer lung function than those whose mothers did not smoke.
The only way for an asthmatic patient to relieve asthma symptoms is to quit smoking.
Sinusitis and other upper respiratory tract infections
As well as inflammation of airway mucosa causes asthma, sinusitis leads to inflammation. This mucosal inflammation leads to the increased mucus secretion. Proper treatment of sinusitis is necessary to alleviate asthma symptoms.
Infections and asthma
Colds, flu, bronchitis, sinusitis can cause an asthma attack. These respiratory infections of viral or bacterial etiology is a common cause of asthma, especially at children younger than 10 years. The increased sensitivity of the airways and the tendency to contraction may last for two months after recovery from infection.
- 70% of asthmatic patients have predisposition to concomitant sinusitis;
- 56% of people with allergic rhinitis (hay fever), sinusitis, are likely to develop asthma.
Medications and Asthma
Many people with asthma are sensitive to aspirin, and possibly also to other anti-inflammatory drugs such as Ibuprofen (Advil, Motrin), Naproxen (Aleve, Naprosyn), Ketoprofen and beta-blockers (used for diseases of the heart, high blood pressure and glaucoma). If you are aware of your sensitivity to these drugs, make sure that the doctor brought this information into your medical map. We also recommend you to consult a pharmacist about the possible effects of the drug.
Other causes of asthma
- Irritants. Many irritants, including tobacco smoke, smoke from fire, wood burning, strong perfume, cleaning products, etc., may be causes that provoke an asthma attack. Furthermore, an attack may be caused by air pollution, including air working area (production), dust or fumes;
- Weather. Cold air, changes in temperature and humidity can also trigger asthma;
- Powerful emotions. Stress and asthma are always close to each other. Anxiety, crying, screaming, stress, irritation or a strong laughter can trigger an asthma attack.
How do these factors provoke an asthma attack?
Asthmatic people, whose airways are always inflamed and very sensitive, react to a variety of external factors easily. The contact with these factors causes the symptoms of asthma, mucus blocks the airways and, as a result, the symptoms worsen. An asthmatic attack may occur immediately after exposure to the provoking factors, or a few days or weeks later.
There are many factors. The reaction to them is individual for each person and can vary. Certain factors can cause inflammation for some people, but other people may be safe. For some people there may be additional causes of asthma, others have none. Detecting and avoiding contact with an asthma trigger, in cases where this is possible, is an important step in controlling asthma.
The best way is to treat asthma with the right medication. You may order asthma inhalers at Asthma Inhalers Online: Ventolin Inhaler, Proventil Inhaler, Advair Diskus, Atrovent Inhaler, Combivent Inhaler, Serevent Inhaler and others.
How can I understand what factors cause asthma?
Think what factors are present at the time of the appearance of asthmatic symptoms. It will be the first step in determining the cause. Despite the fact that the reasons are various, you may not respond to all of them. Some people react to only one factor, the others – just to a few.
Many factors can be identified in the course of tests and examinations. Your doctor may also recommend the use of the device – peak flow meter. A peak flow meter measures the speed and the amount of air exhaled from the lungs. Indicators point to breathing changes and warn of a probable attack approach.
