Do you have low platelets in your blood? Let's talk about this (Thrombocytopenia)!

How are you? Today we are going to talk about a disease that may sound a little serious, but if properly understood, it can be controlled to a large extent. That is the reduction of platelets in the blood, a condition called (Thrombocytopenia) in medical terms. You may have heard this word from a doctor, or you may have seen it in a blood report. Don't worry, we will talk about this simply, in a way that you can understand.

First, let's see what these blood platelets are and why are they so important to us?

Think of it this way: platelets are the tiny soldier-like structures that run through our blood vessels. To be precise, they are a type of very small, colorless cell. Like the other cells in our blood, platelets are produced in the soft tissue inside our bones called the bone marrow.

Now you ask, so why do we need these little soldiers? Here's the important thing: When we get hurt somewhere and start bleeding, like when we're going to war, these platelets are the first to rush there and join together to form a blood clot (`(clot)`) to stop the bleeding. It's like when you put some cement in a hole in a wall. So, without platelets, even a small wound might not be able to stop the bleeding. Do you understand how important that is?

So, what is this low platelet count, or thrombocytopenia?

Simply put, thrombocytopenia is when your blood has fewer than the normal number of platelets. Normally, a healthy person has between 1.5 and 4.5 million platelets per microliter of blood. When this number drops below this, we call it thrombocytopenia.

But here's the thing: a slight drop in platelets isn't always a big deal. It depends on how low it is, why it dropped, and how quickly it dropped. That's why it's important to seek the advice of a doctor.

Why do we have low platelet counts? What are the causes?

There can be a variety of reasons for low blood platelets. Let's divide them into three main categories.

1. If the production of blood platelets by the bone marrow decreases:

We talked earlier about how platelets are made in the bone marrow. So, if there is a problem with this bone marrow and the production of platelets decreases, the number of platelets in the blood decreases. There are several possible reasons for this:

• Some viral infections: For example, infections such as dengue fever, hepatitis C, and HIV can cause bone marrow failure.
• Certain medications: Medications used to treat cancer (Chemotherapy), some antibiotics, and diuretics can also affect the bone marrow.
• Excessive alcohol consumption: This can also damage the bone marrow.
• Vitamin deficiencies: If the body lacks enough vitamin B12 (`(Vitamin B12)`) or folate (`(Folate)`), the production of blood platelets may decrease.
• Blood cancers: Blood cancers such as leukemia can cause the bone marrow to stop producing normal cells.
• Aplastic Anemia: This is when the bone marrow does not produce any blood cells properly.
• Myelodysplastic Syndromes: This is also a condition in which the bone marrow does not function properly.
• Rare genetic conditions: Sometimes, low platelet production can be caused by genetic causes that are present at birth.

2. If the platelets produced are destroyed quickly or if they are used excessively in the body:

Sometimes, even if the bone marrow produces enough platelets, if they are destroyed quickly inside the body, or if they are used up too much due to a major bleed, platelet counts can decrease.

• ITP (Immune Thrombocytopenic Purpura): This is when our immune system mistakenly attacks and destroys our own blood platelets. This can occur in young children after a viral fever, but it can also occur in adults.
• This can also happen in other autoimmune diseases, such as lupus and rheumatoid arthritis.
• Certain medications: Some medications can cause the immune system to destroy blood platelets, even as an allergic reaction.
• Severe infections (sepsis): In severe infections, conditions such as DIC (Disseminated Intravascular Coagulation) can occur, causing rapid depletion of blood platelets.
• TTP (Thrombotic Thrombocytopenic Purpura) (`(Thrombotic Thrombocytopenic Purpura)`) and HUS (Hemolytic Uremic Syndrome) (`(Hemolytic Uremic Syndrome)`): These are rare but dangerous conditions. In this condition, small blood clots form inside the blood vessels and the platelets are used up.

3. If the spleen becomes enlarged and platelets accumulate there:

The spleen is an organ located on the upper left side of our abdomen. It filters blood and removes old blood cells. If the spleen becomes enlarged due to certain diseases (e.g., liver disease - cirrhosis, certain infections, blood cancer), it can accumulate more platelets than normal, causing a decrease in the number of platelets in the blood.

What symptoms can occur when blood platelets are low?

The symptoms of low platelets can vary from person to person. It also depends on how low your platelets are and how quickly they drop. Sometimes people with a low platelet count may not have any symptoms at all. However, here are some of the most common symptoms:

• Bruises: Bruises are large, blue or purple spots on the skin. Even a small bump anywhere can cause a large bruise.
• Small red dots on the skin: Sometimes small red or purple dots (`(petechiae)`) appear all over the body, like small ants. These do not disappear when you look at them.
• It takes a long time for the bleeding to stop after an injury.
• Bleeding gums, frequent nosebleeds.
• Bleeding in the urine or stool (the urine may be red, the stool may be black or bloody).
• For women, the menstrual period is heavier and lasts for more days than usual.
• Feeling tired, fatigue.
• Sometimes, if it is related to a liver problem, the eyes may turn yellow (jaundice).

Important: If you experience symptoms such as a headache, feeling faint, or difficulty speaking, you should go to a hospital immediately, as this could be a sign of bleeding inside the brain!

If we have symptoms like these, what should we do? Should we see a doctor?

Yes, absolutely! If you have any unusual bleeding, blood spots on your skin, or extreme fatigue, don't ignore it and see a doctor. Don't panic, but don't delay either. The doctor will ask you questions, examine you, and refer you for tests if necessary.

How does the doctor diagnose this? What kind of tests do they do?

When you see a doctor, they will first ask about your symptoms, the medications you are taking, and whether anyone in your family has had similar problems. Then they will examine you and check for bleeding, skin discoloration, and an enlarged spleen.

In addition, it is possible to perform tests such as:

• Full Blood Count (FBC) : This is the main test that determines the exact number of platelets in the blood. It also provides information about red blood cells and white blood cells.
• Peripheral Blood Smear : This involves taking a sample of blood and looking at the shape and size of the platelets under a microscope. Sometimes, they also look to see if the platelets are stuck together or if there are any abnormal cells.
• Other blood tests: There are other tests that can help find the cause. For example, tests to check liver function (liver function tests), kidney function tests, tests to check for viral infections, and tests to check for autoimmune markers.
• Bone Marrow Aspiration and Biopsy : Sometimes, if blood tests alone don't reveal the cause, this test is done to see if the bone marrow is producing platelets properly. This involves taking a small amount of bone marrow from a small area, such as the hip, under anesthesia.

What are the treatments for low blood platelets?

This is a problem that many people have. The treatment for low platelets depends entirely on what caused it and how serious the condition is. There is no one-size-fits-all solution.

• For those with mildly low platelet counts: If the platelet count is not very low and there are no signs of bleeding, sometimes no treatment is needed, just observation with regular blood tests.
• Treating the underlying cause:
• If a medication has caused your platelet count to drop, your doctor will either tell you to stop taking the medication or switch you to another medication. Do you think it's best to not stop taking the medication?
• If it is due to an infection, that infection is treated.
• If it's an autoimmune disease, it's treated.
• Treatments specifically for low blood platelets:
• Corticosteroids : For example, medications like prednisolone. These are given to stop the immune system from destroying blood platelets (in conditions like ITP).
• Intravenous Immunoglobulin (IVIG): This is a saline-like medication given into a vein. It is used to quickly increase platelet counts in severe cases where the immune system is destroying blood platelets.
• Other immune system-controlling medications (immunosuppressants): These are given if steroids don't work or if the side effects are too severe.
• Thrombopoietin receptor agonists (TPO-RAs): These medications stimulate the bone marrow to produce more platelets.
• Platelet Transfusion: If you are bleeding heavily or if your platelet count is very low and dangerously low (e.g. before surgery), you may be given platelets externally. However, this is only a temporary solution.
• Splenectomy: If the spleen is found to be responsible for platelet destruction, and other treatments are not effective (especially in long-term ITP), surgery to remove the spleen may be performed. However, removing the spleen does increase the risk of infection.
• Plasma exchange (or Plasmapheresis): This treatment is used in special conditions like TTP.

What should we be concerned about while living with this condition?

People with low blood platelets need to be a little careful in their daily lives.

• Avoid activities that could cause falls and injuries. For example, contact sports are not suitable.
• Be very careful when using sharp tools or cutting vegetables.
• Use a soft toothbrush when brushing your teeth. Be careful not to injure your gums.
• Do not use blood thinners such as aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) (such as ibuprofen) without your doctor's advice. These can increase bleeding. Tell every doctor and dentist you see that you have low platelets.
• Be aware of any signs of bleeding (skin spots, nosebleeds, bleeding gums). Tell your doctor if you notice any new symptoms.
• Eat a balanced diet. Unless your platelet count is low due to a vitamin deficiency, diet alone won't cure it. However, it's important to get the nutrition your body needs.
• Limit or completely stop drinking alcohol .

Can this be serious? What are the complications?

Yes, this can be a serious condition if the platelet count drops significantly or suddenly.

The main risk is severe bleeding. This can be visible (from a wound, nose) or internal (e.g., in the brain, stomach, intestines). Internal bleeding can be life-threatening.

That's why it's so important to take the treatment exactly as the doctor says and to be careful.

Summary and final words

Okay, so I hope you now have a better understanding of what we talked about today (Thrombocytopenia) or low blood platelets. Remember, this means that the platelets in the blood are lower than normal. There can be many causes, and the symptoms are different for each person.

The most important thing is, if you have these symptoms, instead of making decisions on your own, or looking up medication online, find a good doctor, find the exact cause, and get the right treatment for it.

Don't worry, most of the time, with proper treatment and management, you can control this condition and live a good life. Be open and honest with your doctor about everything, and ask any questions you may have. This will help you understand this better and help you cope better.
