Severe Eosinophilic Asthma
Severe Eosinophilic Asthma Overview
Severe eosinophilic asthma is a condition in which the airways become swollen and blocked due to a marked increase in the number of cells called eosinophils. These cells are part of the body’s natural defense system and are normally found in the blood, lungs, and other tissues. In people with severe eosinophilic asthma, there are increased numbers of eosinophils in the airways.
Causes of Severe Eosinophilic Asthma
The exact cause of severe eosinophilic asthma is unknown, but thought to be related to an individual’s genetic makeup, environment, and sensitivity to allergens and other irritants. Allergens, such as pollen and pet dander, may trigger a reaction in people who have the condition. Many individuals also find that certain foods, perfumes, and chemicals can make their asthma worse. It is important to identify and avoid triggers in order to control severe eosinophilic asthma.
Symptoms of Severe Eosinophilic Asthma
The symptoms of severe eosinophilic asthma can be both mild and severe. Common symptoms include:
- Coughing
- Wheezing
- Chest tightness
- Shortness of breath
- Fatigue
- Difficulty sleeping
In some cases, severe eosinophilic asthma can worsen quickly, leading to an asthma attack. This is why it is important to see a doctor for treatment as soon as possible.
Diagnosis and Treatment of Severe Eosinophilic Asthma
In order to diagnose severe eosinophilic asthma, a doctor will perform a physical exam and ask about the patient’s symptoms and medical history. The doctor may also order blood tests and lung function tests to measure the amount of eosinophils present. Treatment will depend on the severity of the condition and may include medications such as inhaled steroids, long-acting bronchodilators, and leukotriene modifiers. Additionally, the doctor may suggest avoiding known asthma triggers.
