Have you ever picked up your Full Blood Count report and looked at the things it says? You must have seen that there is a value called "Platelets" among the things there. Sometimes the doctor says, "Your platelet count is a little high." At that time, it is normal to feel a little scared and worried. "What is this? Is it serious?" You think. So today, let's talk very simply and friendly about this increase in blood platelets, which is a condition called Thrombocytosis in medical terms.
First, let's see, what are platelets?
In simple terms, platelets are a type of small cell in our blood. Think of them as a little 'helper group' that comes to stop the bleeding when you get a cut or a scrape somewhere on your body. They quickly come to the site of the injury, stick together, and form a clot, like a plaster, to seal the wound. This is how the bleeding stops. So you can see that platelets are an indispensable and very important part of our body.
But, like anything, problems can arise when these platelets become too high. Thrombocytosis is when the number of platelets in the blood increases above the normal level. When platelets increase in this way, our blood can sometimes become sticky. This can lead to unwanted blood clots forming in places where there is no injury, that is, inside blood vessels. If these blood clots are not treated, they can even lead to serious conditions like a heart attack or stroke.
There are two main types of thrombocytosis:
Depending on the cause of the high platelet count in your blood, this condition can be divided into two main types. It is important to understand these two, because treatment methods will depend on this type.
| Type of thrombocytosis | Simply put... |
|---|---|
| Reactive Thrombocytosis (Secondary) | This is the most common type. What happens here is that the number of platelets increases as a 'response' to another condition or event in your body. It's like everyone panicking when a burglar breaks into your house. The problem here is not where the platelets are made, but somewhere else. This condition is usually temporary . |
| Essential Thrombocytosis (Primary) | This is a bit rare. The problem here is in the bone marrow, the 'factory' where blood cells are produced. Due to some defect in the bone marrow, they produce too many abnormal platelets. This is the 'primary' or underlying cause. |
However, if your blood test shows that your platelet count is high, it means that something is going on inside your body that needs to be investigated by a doctor. Depending on the cause of the finding, you may need long-term treatment, short-term treatment, or no treatment at all.
What are the symptoms of high platelet count?
In fact, many people do not experience any symptoms of high platelet count. It is discovered incidentally when a blood test is done for another reason.
If you have Reactive Thrombocytosis, you may experience symptoms of the underlying condition (for example, fever from an infection).
However, if the increase in platelets causes blood clots to form or (very rarely) internal bleeding, some symptoms may occur. This condition is most commonly seen in Essential Thrombocytosis.
- Fatigue
- Frequent nosebleeds
- Bleeding (bruising) even after a small injury
- Easy bleeding from the gums or other areas inside the mouth
- Dizziness , blurred vision, and headache
- Pain, swelling, and redness in the hands and feet (a symptom of a condition called erythromelalgia)
- Abdominal pain, especially in the upper right side of the abdomen (may be a sign of a condition such as Budd-Chiari syndrome)
The important thing is that not all of these symptoms are specific to Thrombocytosis. So if you have something like this, it's best to not panic and see your doctor and talk about it.
Why do platelets increase like this? What are the reasons?
The reasons also vary depending on the two types we discussed earlier.
Causes of Essential Thrombocytosis (ET)
This is caused by genetic mutations. But this is not something that is born with, but something that develops over time. Simply put, there is a change in the genes that tell our body to make platelets. As a result, the bone marrow starts making too many platelets without control.
Causes of Reactive Thrombocytosis
This is simply the body's response to another problem. Here are some common causes of high platelets:
- Bleeding: When there is a lot of blood loss due to an accident or surgery.
- Cancer conditions: Due to some types of cancer.
- Infections: Bacterial or viral infections.
- Inflammatory conditions: Diseases that cause inflammation in the body, such as arthritis.
- Iron-deficiency anemia.
- Some medications.
- Surgical removal of the spleen: One of the functions of the spleen is to remove old platelets. Removing it can increase platelet counts.
What complications can occur due to this condition?
People with Essential Thrombocytosis (ET) are at higher risk of complications. Complications are very rare in Reactive Thrombocytosis.
The biggest risk is the formation of blood clots . If these blood clots become stuck in a blood vessel leading to the brain, they can cause a stroke , and if they become stuck in a blood vessel leading to the heart, they can cause a heart attack . These blood clots can also form in other places, such as the lungs and legs.
Very rarely, ET can develop into other blood cancers, such as leukemia, or cause scarring of the bone marrow (myelofibrosis). It can also increase the risk of certain complications during pregnancy.
But don't worry. If you have ET, your doctor will be monitoring your health closely and will provide you with the necessary treatment to prevent complications like these.
How do doctors find this out exactly?
Thrombocytosis is primarily diagnosed through blood tests. Typically, a platelet count of more than 450,000 per microliter of blood is considered high. Your doctor may want to retest your blood after a few weeks to see if your platelet count is still high. If the count has returned to normal, it is usually nothing to worry about.
If the platelet count continues to be high, the next step is to determine whether it is Reactive or Essential. This will require several more tests.
- Other blood tests: These check things like iron levels and inflammatory markers, and look for abnormal platelet shapes under a microscope.
- Genetic tests: This test can detect genetic mutations such as JAK2 , CALR1 , or MPL1, which are commonly seen in Essential Thrombocytosis.
- Bone marrow biopsy: This involves taking a very small sample of bone marrow from a site such as the hip bone under anesthesia and testing it in a laboratory. This can definitively confirm the ET condition.
How is it treated?
Treatment options depend on the type of thrombocytosis you have and your symptoms.
For Reactive Thrombocytosis:
This is when platelets increase in response to another disease. Therefore, the treatment is aimed at the underlying cause . For example, if the platelet count is increased due to an infection, when antibiotics are given for that infection, the platelet count will return to normal as the infection heals.
For Essential Thrombocytosis (ET):
ET is not a curable disease. However, it can be managed well to reduce the risk of blood clots. There are several treatment options:
- Watchful waiting: If you have no symptoms and your risk of developing blood clots is low, your doctor may monitor your condition by doing regular blood tests without prescribing any medication.
- Low-dose aspirin: You may be prescribed a daily aspirin pill to help prevent blood clots. But remember, never start taking aspirin on your own without consulting a doctor.
- Medications that lower platelet levels: Medications such as Hydroxyurea, Anagrelide, and Interferon alfa control platelet production.
- Platelet removal procedure: If there is an immediate risk of developing a life-threatening blood clot, your blood may be passed through a machine to filter out excess platelets.
When should you see a doctor?
If you have been diagnosed with thrombocytosis, it is important to have regular blood tests as directed by your doctor. Also, ask your doctor what symptoms you should report immediately if they occur.
In particular, if you develop symptoms of a stroke or heart attack (e.g. sudden chest pain, difficulty speaking, weakness on one side of the body, facial drooping), go to a hospital's Emergency Department (ETU) immediately.
Remember, don't panic when you see a high platelet count on your blood report. It's just a snapshot of your body's condition at that moment. Most of the time, it's a sign of a temporary, easily treatable condition. Rarely, it's a sign of a long-term condition. However, there are good treatments available today to manage it.
