What Are The Causes of Asthma?
What Are The Causes of Asthma? The exact causes of asthma is still unknown. However, there are some things that can trigger the appearance of symptoms of this disease, including:
- Lung and respiratory infections commonly invade the upper airway such as flu.
- Allergens (animal dander, dust mites, and flower powder).
- Exposure to substances in the air, such as chemical fumes, cigarette smoke, and air pollution.
- Factors of weather conditions, such as cold weather, windy weather, hot weather supported poor air quality, humid weather, and drastic temperature changes.
- The interior condition of the room is damp, moldy, and dusty.
- Excessive emotion (sadness that drags on, excessive anger, and laugh out loud).
- Physical activity (eg sports).
- Drugs, such as non-steroidal anti-inflammatory painkillers (aspirin, naproxen, and ibuprofen) and beta-blocking drugs (usually given in people with heart problems or hypertension).
- Food or beverages containing sulfites (natural substances sometimes used as preservatives), such as jams, shrimp, processed foods, fast food, fruit juice, beer and wine drinks.
- Food allergies (eg beans).
- Gastroesophageal reflux disease (GERD) or a disease in which stomach acid returns up into the esophagus so that it irritates the upper gastrointestinal tract.
It is important to know what often triggers the appearance of symptoms if you are an asthma sufferer. Once you know it, avoid these things because it is the best way for you to prevent the occurrence of asthma attacks.
Risk factors for Causes of Asthma
Respiratory tracts of people with asthma are more sensitive and susceptible to inflammation compared with normal people when irritated by the above-mentioned triggers.
When asthma symptoms appear, the respiratory tract will narrow and the muscles around the channel tighten. In addition, there is an increase in inflammation in the lining of the respiratory tract and the production of sputum which further adds to the narrowing of the respiratory tract.
By narrowing the parts of the respiratory tract, the air will be harder to flow and the patient becomes more difficult to breathe.
According to the study, there are several factors that can increase a person’s risk for developing asthma, including:
- Have a family with a history of asthma or
- Atopic allergy (allergy-related conditions, such as food allergies and eczema).
- Have bronchiolitis or lung infection as a child.
- Born underweight, ie less than two kilograms.
- Premature birth, especially if you need a ventilator.
- Exposed to cigarette smoke as a child. In the case of mothers who smoke during pregnancy, the risk of children suffering from asthma will increase.
