You must have been a little shocked when you saw that your blood test showed a high number of granulocytes, a type of white blood cell. Your doctor may have told you about it. Is this really something to be afraid of? Let's talk about this simply, in a way that you can understand.
What is Granulocytosis?
Simply put, the white blood cells in our bodies are like the body's security guards. A special group of white blood cells called granulocytes are found in our blood and sometimes in our tissues.
There are several main types of granulocytes:
- Neutrophils
- Eosinophils
- Basophils
- There is also a type of cell called mast cells in tissues.
All of these work together to fight germs and allergens that enter our bodies, and to control inflammation. Imagine, when a germ enters our bodies, these granulocytes are the first to go and fight it.
So, when the number of granulocytes in the blood is higher than normal, it is called granulocytosis . This usually means that there is something wrong with the body, especially an infection.
Not only that, sometimes the number of granulocytes can increase due to autoimmune diseases (for example, rheumatoid arthritis, which is a disease in which our body's immune system attacks our own cells) or bone marrow conditions (for example, blood cancer conditions such as chronic myeloid leukemia (CML)).
But don't be too alarmed when you hear that your granulocytes are high. There can be many reasons for this, not all of which are serious. Your doctor will tell you more about this.
What is the difference between Granulocytosis and Leukocytosis?
These two words can seem a bit confusing. Leukocytosis refers to an increase in the total number of white blood cells in our blood. This includes not only granulocytes, but also other types of white blood cells called monocytes and lymphocytes.
But granulocytosis is only an increase in a type of cell called granulocyte (that's the neutrophils, eosinophils, and basophils we talked about earlier). Do you understand?
What is the difference between Granulocytosis and Agranulocytosis?
This is the other side. Granulocytosis is an increase in granulocytes. Agranulocytosis is when our bone marrow does not produce enough of a special type of granulocyte called neutrophils. This means that these cells decrease. This is also a condition that needs to be taken care of.
What are the symptoms of this condition?
The symptoms of granulocytosis vary greatly depending on the cause. The way each person feels can also vary. Sometimes, it can be found accidentally during a blood test for another condition, without any symptoms.
Imagine you have a bacterial infection . You may experience symptoms like these:
- Headache
- Fever
- Tiredness, feeling of weakness
- Nausea, vomiting
Or, if you have a condition like rheumatoid arthritis , where these granulocytes are increased, you may experience things like:
- Joint pain (arthritis)
- Joint stiffness and swelling in the morning, as if it is difficult to stretch the limbs
Sometimes, it can also be caused by a blood cancer condition, such as Chronic Myeloid Leukemia (CML) . In that case, you may experience symptoms like:
- Constant fatigue
- Night sweats
- Feeling full even after eating a little (feeling like you are full quickly)
- Swelling or discomfort in the upper left side of the abdomen (may be due to an enlarged spleen)
These are some of the main symptoms that you may see. However, just having these symptoms does not mean that you have granulocytosis. That is why it is important to see a doctor to get an accurate diagnosis.
What are the causes of Granulocytosis?
There are many reasons that can affect this condition. Some of them are short-term problems that get better in a few days. Some of them can be long-term (chronic) illnesses.
The main reasons seen are:
- Infections: Various infections caused by bacteria, viruses, and parasites. For example, pneumonia, dengue fever, or even a severe cold can cause this.
- Autoimmune diseases: As we have discussed before, diseases such as Rheumatoid Arthritis and Lupus are caused by a malfunction in our body's own immune system.
- Myeloproliferative neoplasms: These are rare types of blood cancers. Examples include conditions such as chronic myeloid leukemia (CML), polycythemia vera, and essential thrombocythemia.
Other reasons:
- Sepsis: A severe infection that spreads throughout the body. This is a condition that requires emergency treatment.
- Heart attack.
- Kidney failure.
- Metastatic cancer: Cancer that has started in one place in the body and spread to other places.
- Inflammatory bowel disease: Inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis).
- Severe burns.
- Smoking: Smokers can also have an increased number of these cells.
- Severe emotional or physical stress: Such as after major surgery or after a major trauma.
- Some medications: For example, medications like corticosteroids and lithium can also cause it.
How is this condition of granulocytosis diagnosed?
The doctor will first ask you about your medical history, what problems you are experiencing, what medications you are taking, etc. Then he will examine you. If he has any doubts about this, he will ask you to do a complete blood count (CBC) . This is a common blood test, for which a small sample of your blood is taken.
What is the correct amount and severity of granulocytosis?
Normally, a healthy person should have between 1,500 and 8,500 granulocytes per microliter of blood. Anything above this number is called granulocytosis.
To elaborate further, here are the normal amounts of each type of granulocyte in the blood:
- Neutrophils: 1,800-7,800 cells per microliter of blood.
- Eosinophils: 0-450 cells per microliter of blood.
- Basophils: 0-200 cells per microliter of blood.
The numbers on these lab reports can be hard to understand sometimes, right? So if you have any questions about what's on your report, definitely talk to your doctor and explain. He or she will explain what those numbers mean to you.
How is this treated?
The treatment for granulocytosis depends on the underlying cause . Simply put, treating the cause often returns the number of these cells to normal.
Let's look at some examples:
- If it is due to infections: Antibiotics can be given for bacterial infections. For viral infections, there is often no specific medicine, just rest and fluids.
- If it is due to autoimmune conditions: Immunosuppressants (e.g. corticosteroids) may be given.
- If it is due to cancer (e.g. CML): Depending on the type and stage of the cancer, you may need to undergo treatment such as chemotherapy, radiation therapy, targeted therapy (these are newer drugs that only affect cancer cells), or possibly a bone marrow transplant.
Regardless of the reason for your high granulocyte count, your doctor will determine the most appropriate treatment for you. The most important thing is to treat the underlying condition properly. Then the granulocyte count should also decrease.
Is there a way to prevent this situation?
Granulocytosis is often caused by another disease or condition. So, since we cannot prevent all of these diseases, it is difficult to say that this condition can be completely prevented. For example, some causes can be minimized by things like staying clean to protect against infections, eating a balanced diet, and avoiding smoking.
If you experience this condition, don't panic. Your doctor will investigate the cause and recommend the best treatment.
If I have granulocytosis, what should I expect?
If your complete blood count (CBC) shows granulocytosis, your doctor will next look for conditions that could be causing it. He or she may also order further tests.
Then, if you need treatment, you can talk about it. Sometimes, depending on the cause, long-term treatment may be needed to control the condition and bring the granulocyte level back to normal. But there are some cases, for example, if this is caused by a minor infection, when the infection gets better, the condition will get better on its own, without any special treatment, and the granulocyte level will decrease.
Your doctor will explain to you exactly what to expect, based on your diagnosis, so don't be afraid to ask any questions you may have.
How long does granulocytosis last?
This also depends on the underlying cause. Granulocytosis usually goes away once the underlying cause is treated, or the medication that caused it is stopped (this can happen as a side effect of some medications). This can take a few days or weeks, depending on your condition. In some long-term conditions, granulocytes may remain elevated until the condition is controlled.
When should I see a doctor?
If you feel something strange or uncomfortable in your body, or if you experience symptoms that you didn't have before, such as fever, body aches, extreme fatigue, or joint pain, it's best to see a doctor at any time. Because the symptoms of granulocytosis can be similar to those of many other diseases, it's important to see a doctor to find out exactly what's wrong.
If you are already being treated for a condition related to granulocytosis, and you feel your symptoms getting worse or if you develop new symptoms, talk to your doctor right away. He or she can help you manage your symptoms.
What questions should I ask my doctor?
Having a good understanding of your blood test results and your condition will help you make informed decisions about your health. If you have granulocytosis, you can ask your doctor these questions:
- How high is my granulocyte count? What does it mean?
- What conditions do you suspect? What tests are needed to confirm them?
- What are the treatments for this? What can you expect from the treatment?
- Do I need to make any changes to my lifestyle?
- How long will this condition last? Can it occur again?
Finally, things to remember
Granulocytes are very important soldiers in our immune system. These cells help protect our body from various infections.
However, an excessive number of granulocytes in the blood can indicate an underlying health problem. If you have granulocytosis, your doctor will investigate the cause. Once the cause is found, he or she will develop a treatment plan that is right for you.
The most important thing is to not panic, to follow your doctor's instructions, and to get the tests and treatment you need. If your diagnosis is something serious like cancer, there are many resources and groups you can turn to for more information and support. Ask your doctor about that too. You are not alone, and there are many people, including doctors, who can help you on this journey.
