J45.03: Predominantly allergic bronchial asthma, specified as well controlled and severe

You have asthma.

The air is breathed in through the mouth or nose. From there the air goes into the trachea via the larynx. At the end of the windpipe are two bronchial tubes (or bronchi) branching away from it. The bronchial tubes run into the lungs. What is more, the bronchial tubes divide into even smaller branches. The larynx, the trachea, the bronchia and the lungs are part of the lower airways.

With asthma, the bronchial tubes are permanently inflamed. The bronchial tubes are also very sensitive. Certain triggers can make them narrow for a time. A number of things can cause asthma.

In your case the main cause is an allergy. With an allergy, the immune system overreacts to certain substances. Such substances may be harmless substances in the environment, drugs or certain chemicals, for example.

Typical symptoms of asthma are coughing and breathlessness. An asthma attack also results in increased breathlessness and tightness in the chest. Asthma symptoms can get worse if you have been infected by pathogens. This may be the case with a common cold, for example.

You have a severe asthmatic illness that is being treated long-term with medication. However, your asthma is being controlled by the medication. Asthma can be deemed to be controlled, for example, if it does not impair everyday life or sleep.
