Eosinophils increase in cases of allergic reactions, parasitic infections, and certain cancers.
Understanding Eosinophilia
High levels of eosinophils, a condition known as eosinophilia, often indicate an underlying health issue. These white blood cells are a part of your immune system and play a role in fighting infections and inflammation. Here's a breakdown of the primary causes for their increase:
Allergic Reactions
- Asthma: Eosinophils contribute to airway inflammation in asthma.
- Allergic Rhinitis: Commonly known as hay fever, this condition causes nasal inflammation due to allergens.
- Dermatitis: Various skin conditions like eczema can trigger an increase in eosinophil levels.
These allergic reactions lead to increased eosinophil production as the immune system overreacts to perceived threats.
Parasitic Infections
Parasites are a common trigger for elevated eosinophil counts. This response is part of the body's defense mechanism against these invaders. Examples of parasitic infections include:
- Intestinal worms
- Tissue parasites
Eosinophils are sent to help kill and remove these parasites from the body.
Certain Cancers
Certain malignancies can cause an increase in eosinophils, including:
- Hodgkin Lymphoma: A cancer of the lymphatic system.
- Leukemia: A cancer of the blood and bone marrow.
In these cases, the abnormal growth of cancerous cells can sometimes trigger an elevated eosinophil response.
Summary
In summary, the main reasons for increased eosinophil counts are:
- Allergic Reactions: Resulting in conditions like asthma, allergic rhinitis, and dermatitis.
- Parasitic Infections: The immune system’s response to infections.
- Cancers: Including Hodgkin lymphoma and leukemia.
It's essential to consult a healthcare professional if you suspect you have eosinophilia, as identifying and addressing the root cause is critical.
