Basics
The term asthma stands for a chronic disease of the respiratory tract. If one suffers from asthma, then one suffers from episodic coughing attacks that can lead to respiratory distress and suffocation. The airways narrow and make it impossible for the patient to breathe in and out normally. Generally speaking, when you have asthma, you suffer from a very high level of inflammation in the airways, and the airways are hypersensitive to certain stimuli.
Bronchial asthma is one of the most common respiratory diseases in the world. Even children and teenagers can suffer from this disease. Research has shown that children are particularly prone to asthma if their parents have been diagnosed with allergies. The child is especially likely to develop asthma if the parent's allergy is related to the airways.
Asthma is a permanent disease that cannot be cured, but can be significantly alleviated. Thanks to numerous modern treatment methods, it is now possible to guarantee the sufferer an active and symptom-free life without being too restricted by the disease.
What changes in our body when we suffer from asthma?
Inhalation: When we breathe in, the chest expands and the lungs expand; negative pressure causes air to be sucked in.
The air we breathe enters our trachea through the mouth or nose, and from here it travels to the left or right lung, where it branches out into numerous smaller and smaller branches, reaching the smallest corners of the lung.
The bronchial system finally ends in the alveoli (= alveoli). This is where the gas exchange of the lungs takes place.
The heart pumps oxygen-poor blood into the lungs, which flows through the branching blood vessels to the alveoli, where it is separated from the inhaled air by a delicate membrane.
The blood releases carbon dioxide and in return takes in oxygen. Now the blood is oxygenated and can flow back to the heart to be distributed throughout our body.
In asthmatics, there is inflammation of the bronchial system. The small branches of the bronchial tree are affected by such inflammation. Due to a disturbance of this bronchial system, over irritation and attack occurs.
In this case, the inflamed mucous membrane swells, the cross-section of the tubular system becomes smaller, the air can flow through less easily, and the asthma sufferer finds it more difficult to exhale.
In addition, the muscles of asthmatics react particularly sensitively. The muscular ring contracts like a spasm. This restricts the obstructed air flow even more.
In addition, the asthmatic's inflamed bronchial system produces a viscous and thick secretion that cannot be easily removed from the lungs and therefore accumulates in the airways. To get rid of the mucus, asthma sufferers have to cough more.
These three factors lead to a narrowing of the airways (= obstruction). Breathing in is largely unhindered, but when breathing out, the obstruction becomes noticeable.
This is why air collects in the lungs during an asthma attack and cannot be exhaled again.
