Brittle Asthma

Brittle asthma (pronunciation: /ˈbrɪtl/ /ˈæzmə/) is a rare form of asthma that is difficult to control and can cause severe health problems.

Etymology

The term "brittle" in this context is derived from the English word "brittle", which means "hard but liable to break or shatter easily". It is used to describe this type of asthma because of its unpredictable and sudden changes in severity.

Definition

Brittle asthma is characterized by frequent, severe attacks and a high level of variability in peak expiratory flow, despite high doses of corticosteroids. It is divided into two types: Type 1, which is characterized by a wide, variable peak expiratory flow, and Type 2, which is characterized by sudden severe attacks of asthma.

Symptoms

Symptoms of brittle asthma are similar to those of regular asthma, but they are more severe and unpredictable. They include shortness of breath, wheezing, coughing, and chest tightness.

Causes

The exact cause of brittle asthma is unknown, but it is thought to be related to a combination of genetic and environmental factors. Triggers can include allergens, exercise, cold air, and stress.

Treatment

Treatment for brittle asthma typically involves high doses of corticosteroids and bronchodilators. In some cases, hospitalization may be required.
