Is your blood test showing high eosinophil count? (Eosinophilia) - Let's talk about this!

Have you ever had a blood test and seen that the number in front of the word `(Eosinophil)` on the report was higher than normal? You might have felt a little scared when you saw that. You might have thought, "What is this? Is this a serious illness?" This is actually something that happens to many people. So today, let's talk about what `(Eosinophilia)` is, why it happens, and what we need to know about it.

Simply put, what is Eosinophilia?

Okay, first let's see who these `(Eosinophils)` are. Imagine that our body is like a country. There is an army to protect this country. That army is our immune system . The different types of soldiers in this army are our white blood cells. `(Eosinophils)` are a group of soldiers who have received special training.

They have two main duties:

1. Fighting Allergies: When something that causes an allergy (allergen) enters our body, these ``Eosinophil'' soldiers go there and start a fight.

2. Fighting certain infections: These people are also very good at fighting parasites, especially things like worms, and some fungal infections.

So `(Eosinophilia)` means that for some reason the number of these `(Eosinophil)` soldiers in your blood is higher than normal. Medically speaking, an increase of more than 500 `(Eosinophils)` per microliter of blood is considered `(Eosinophilia)`.

Is an elevated eosinophil count a serious condition?

This is a question that many people have. The answer is, "It depends on the cause."

It can be classified as mild, moderate, or severe depending on how high the eosinophil count is.

• Often, the cause behind this is something less serious. For example, it could be an allergy to dust, a skin condition (such as eczema, hives), asthma, or a reaction to a medication you're taking.
• Sometimes this can be due to something more serious. For example, it can be a sign of a serious infection, a problem with the immune system, or, very rarely, some blood cancers.

Sometimes, many of these `(Eosinophil)` cells gather together and cause inflammation in one place in the body. We call such conditions `(Eosinophilic disorders).`

What are the main causes of elevated eosinophil levels?

Imagine that the alarm in your house is going off. It could be a mouse or a thief. ``(Eosinophilia)`` is one such alarm. The doctor is the one who finds the cause.

Here are some of the main reasons:

• Allergies and Asthma: This is the most common cause of ``(eosinophilia).`` This number can increase due to allergies to things like dust, pollen, certain foods, and animal dander.
• Infections: Parasitic infections, especially worm infections, are very common in our country. In such infections, the body produces a large number of eosinophils.
• Skin Conditions: People with skin conditions like eczema may also have high levels of eosinophils.
• Drug Reactions: For some people, eosinophil counts may increase as a reaction to certain medications, such as painkillers or antibiotics.
• Autoimmune Diseases: These are diseases in which our body's own defense system malfunctions and attacks our own healthy cells. For example, diseases like `(Inflammatory Bowel Disease)` and `(Vasculitis)`.
• Blood Cancers: Very rarely, eosinophil counts can be abnormally high in cancer conditions such as leukemia.

Specific conditions that can occur when eosinophil counts are elevated

As mentioned earlier, sometimes these `(Eosinophil)` cells accumulate in one place in the body and cause inflammation, that is, inflammation. These are called `(Eosinophilic disorders)` or `(Hypereosinophilia syndrome - HES)`. These are named according to the part of the body where the cells accumulate.

What are the symptoms of eosinophilia?

Remember this: Eosinophilia does not have specific symptoms . The symptoms you experience are related to the underlying condition that caused the Eosinophilia.

For example:

• If the cause is asthma , you will experience symptoms such as difficulty breathing and chest tightness .
• If the cause is worms , symptoms such as stomach aches, weight loss, and itching may occur.
• If the cause is a skin allergy , you will experience symptoms such as redness, itching, and eczema .

That means, the symptoms are not caused by an increase in the number of eosinophils, but by the disease that caused the increase.

How do doctors diagnose and treat this?

Most of the time, this is discovered by chance. The doctor notices an elevated eosinophil count during a routine blood test for another condition, a complete blood count (CBC) .

After that, your doctor may do some more tests to find the cause. This will depend on your symptoms and medical history.

• Allergy test
• Stool tests (to check for worm eggs)
• Chest X-ray examination

When it comes to treatment, the most important thing here is that the treatment is not for the eosinophil count, but for the disease that caused the increase in the count.

• If the cause is an allergy, medication will be given to control the allergy.
• If the cause is worms, deworming medication is given.
• If the cause is a reaction to a medication, that medication will be discontinued and another medication will be prescribed.
• If the cause is a condition like `(Eosinophilic esophagitis)`, medications like `(Steroids)` may be prescribed.

Therefore, if your blood report shows a high level of ``(Eosinophil)'', only your doctor can provide the best solution.
