Chronic myeloproliferative disorders (conditions where the bone marrow makes too many blood cells) can cause high platelet counts. These include polycythemia vera, essential thrombocythemia (ET, also known as primary thrombocythemia), 2 and primary myelofibrosis.
What are high platelets a sign of?
Previous studies have suggested a link between thrombocytosis and various cancers, with recent guidelines from the National Institute for Health and Care Excellence advising high platelet counts could be a sign of cancer of the oesophageal, stomach, lung or uterus.
What are the causes of elevated platelet levels?
The most common cancers to cause elevated platelets include ovarian cancer, gastrointestinal cancer, lung cancer, and breast cancer. 4 What Doctors Look For When evaluating the cause of elevated platelets, doctors will be looking for signs or symptoms that may be present to help determine the cause. These symptoms may include: 3
What would cause increase in blood platelets?
Why do Platelets Increase
- The increase in the number of platelets is known medically as thrombocytosis. ...
- Infections such as those from viruses or bacteria are the most common cause of increased blood platelets.
- A poor diet, unbalanced or low in nutrients, can also be the cause of increased platelet levels and iron deficiency anaemia.
What does it mean to have large platelets?
Macrothrombocytopenia, as it is formally known, occurs when the normally small and highly fragmented platelets are bigger than usual. Many people who have large platelets also have a reduced platelet count. The platelet size can be genetic, as seen in people with Bernard-Soulier syndrome, gray platelet syndrome, and May-Hegglin anomaly.
What is elevated platelet count?
In general, a platelet count more than 450,000 cells per microliter is considered elevated; this is known as thrombocytosis. There are numerous causes of thrombocytosis and fortunately, the majority are benign and transient. Let's review some of the most common causes.
What cancers have elevated platelets?
This is more common in solid tumors like lung cancer, hepatocellular (liver) carcinoma, ovarian cancer, and colorectal cancer. Elevated platelet count can also be seen in chronic myelogenous leukemia (CML) .

If the spleen is removed surgically ( splenectomy) 4 or stops functioning properly (functional asplenia) as in sickle cell disease, thrombocytosis results . This thrombocytosis is usually mild to moderate and well tolerated.
What causes blood clots in et?
With these conditions, the excessive numbers of platelets cause the blood to be thick and flow more slowly which may result in blood clots. Treatment is aimed at reducing the platelet count to reduce this risk. 2 .
What causes thrombocytosis in the bone marrow?
Chronic myleoproliferative disorders (disorders where the bone marrow makes too many blood cells) can cause thrombocytosis. These include polycythemia vera, essential thrombocythemia (ET), 1 and primary myelofibrosis. In ET, for example, the bone marrow makes too many megakaryocytes, the cells that make platelets, resulting in thrombocytosis.
What are the most dangerous complications of thrombocytosis?
The most dangerous complication for most people with thrombocytosis is blood clots. Pregnant women also may have serious complications that include miscarriage, slowed fetal growth, or placental abruption. 10
What causes thrombocytosis?
Conditions with inflammation, like rheumatologic disorders, inflammatory bowel disease, and vasculitides, can have thrombocytosis. 5 The elevated platelet count occurs in response to cytokines (small proteins released from cells that signal other cells to do something). In particular, the cytokines interleukin-6 and thrombopoietin stimulate platelet production.
What are the symptoms of high platelet count?
Watch out for these common high platelet count symptoms. Frequently occurring symptoms include: Headache, the most common neurological symptom. Others include problems with speech, dizziness, fainting, loss of vision and seizures.
What is the definitive diagnosis of elevated platelet count?
The definitive diagnosis can be made after relevant laboratory procedures and measurements of platelet levels. Elevated platelet count causes symptoms that may also require the analysis to be carried further for the identification of associated factors like anemia and increase in leukocytes.
Why does thrombocytosis not last?
If the cause is due to previous surgery or injury that have resulted to a significant loss of blood, thrombocytosis will not last long. If the cause is due to chronic infection or inflammatory disease, platelet levels may remain elevated until the condition is brought into control.
What percentage of polycythemia patients have increased platelet count?
Increased platelet count has also been observed in approximately 66% of patients with polycythemia vera. About 5% of the patients have marked thrombocytosis (platelet count greater than 1000 x 10 9 / L).

People with BSS usually show signs of mucocutaneous hemorrhage in their first year of life. The main symptoms are:
What does it mean when platelets are above or below reference range?
Maybe two things?: Platelets that are a little bit above or below reference range size seldom mean anything if the platelet count itself is normal and there's nothing to suggest compensated autoimmunity. Hypersegmented neutrophils suggest B12 or Folic Acid deficiency from some cause as the first possible problem worth checking.
What are the causes of macrocytosis?
Folate and B12 def: Deficiency of folate and or B12 vitamins can cause macrocytosis and hyper-segmented neutrophils. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats.

Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex.
What does it mean when your platelets are high?
In secondary thrombocytosis, high platelets occurs as a symptom of another disease or condition, such as anemia, infection or cancer. In many cases, high platelets may not produce specific symptoms. In other cases, the elevation in platelet levels leads to the development of unwanted and unnecessary blood clotting throughout the body, ...
What causes high platelets in secondary thrombocytosis?
A wide range of diseases and conditions may cause high platelets including: Anemia (low red blood cell count) Blood loss. Cancer.
What other symptoms might occur with high platelets?
High platelets may accompany other symptoms, which vary depending on the underlying disease, disorder or condition. However, some people who have high platelets may not experience any other symptoms. In these individuals, high platelets may only be detected through routine blood tests.
What is high platelet count?
High platelets is a condition in which the blood contains more platelets than normal. Platelets are small blood cell fragments that assist in blood clotting. In a healthy person, there are usually 150,000 to 450,000 platelets per microliter of blood. A high platelet count can be identified through routine blood tests.
What is thrombocythemia?
Thrombocythemia is a condition in which high platelets occur as an independent condition without another known cause. In this condition, the bone marrow makes too many platelets. This condition may be inherited.
How to identify high platelets?
A high platelet count can be identified through routine blood tests. The occurrence of high platelets is divided into two medical categories: primary thrombocythemia and secondary thrombocytosis. In primary thrombocythemia, the cause of the high platelets is not known, and it occurs as an independent condition.

Myelodysplasia (group of conditions in which the blood cells are abnormal in development or function) Myelofibrosis (disorder that results in scar tissue in the bone marrow) Polycythemia vera (rare bone marrow disorder causing excessive production of blood cells) Reaction to certain medications, including steroids.
Why are my platelets elevated?
Though these may seem like significant numbers, it is important to remember that the majority of elevated platelet counts are caused by a reactive process, such as infection or inflammation. Once the cause of the reactive process resolves, platelet counts generally return to normal levels.
Why are there so many platelets in the blood?
In primary thrombocytosis —also referred to as essential thrombocythemia—the high number of platelets being made is due to an abnormality in how the bone marrow is making them. A mutation may exist in the JAK2 gene, which causes an enzyme to work too much at making platelets. A mutation in the CALR gene can also cause too many platelets ...
What causes platelets to rise in the bone marrow?
A mutation in the CALR gene can also cause too many platelets to be made in the bone marrow. 2. Secondary thrombocytosis can also be called reactive thrombocytosis, as the platelets rise in response to something outside of the bone marrow, such as an infection, inflammation, or bleeding. 3.
What is the normal number of platelets in blood?
Platelets are made in the bone marrow, which is inside the bones of the body. The normal number of platelets is about 150,000 to 450,000 in a blood sample. Having a platelet level greater than 450,000 is called ...
What is the normal platelet count?
The normal number of platelets is about 150,000 to 450,000 in a blood sample. Having a platelet level greater than 450,000 is called thrombocytosis. 1. Learn more about when to worry about high platelet count. SCIEPRO / Getty Images.
What is the term for a disease that causes too many platelets to be made?
The myeloproliferative disorder that causes too many platelets to be made is called essential thrombocythemia, introduced above.
Why is my platelet count high?

What are the symptoms of a giant platelet disorder?
Abnormality of the abdomen, nosebleeds, heavy menstrual bleeding, purpura, too few platelets circulating in the blood, and prolonged bleeding time have also been listed as symptoms of various giant platelet disorders.
What is the color of platelets?
One normal platelet can be seen in the upper left side of the image (purple) and is significantly smaller in size than the red blood cells (stained pink). Giant platelet disorders, also known as macrothrombocytopenia, are rare disorders featuring abnormally large platelets, thrombocytopenia and a tendency to bleeding.
What is the color of platelets in a microscope?
Giant platelet disorder. Two giant platelets (stained purple) are visible in this image from a light microscope (40×) from a peripheral blood smear surrounded by red blood cells. One normal platelet can be seen in the upper left side of the image (purple) and is significantly smaller in size than the red blood cells (stained pink).
Is giant platelet disorder genetic?
Genetics. Many of the further classifications of giant platelet disorder occur as a result of being genetically passed down through families as an autosomal recessive disorder, such as in Bernard-Soulier syndrome and gray platelet syndrome.
Can giant platelets stick to blood vessels?
Giant platelets cannot stick adequately to an injured blood vessel walls, resulting in abnormal bleeding when injured. Giant platelet disorder occurs for inherited diseases like Bernard–Soulier syndrome, gray platelet syndrome and May–Hegglin anomaly.
Is there a treatment for giant platelet disorder?
Treatment. There has been no general recommendation for treatment of patients with giant platelet disorders , as there are many different specific classifications to further categorize this disorder which each need differing treatments. Platelet transfusion is the main treatment for people presenting with bleeding symptoms.
What are the conditions that can be indicated by giant platelets?
Other conditions that can be indicated by giant platelets include gray platelet syndrome and May-Hegglin anomaly. Gray platelet syndrome causes giant platelets which are characterized by a gray color.
What do giant platelets indicate?
Giant platelets can indicate Bernard-Soulier syndrome. Bernard-Soulier syndrome is a very rare blood clotting disorder. It is hereditary, and is characterized by unusually large platelets and low platelet count. Although rare, Bernard-Soulier syndrome is the most likely cause of giant platelet disorder. Sometimes, the terms “giant platelet syndrome” and “Bernard-Soulier syndrome” are actually used interchangeably.
What is the cause of Bernard-Soulier syndrome?
The giant platelets cause comes from a genetic abnormality. The gene responsible for the syndrome has been mapped to the short (p) arm of chromosome 17.
Why are platelets important?
These chemicals facilitate the elaborate and complex process of blood clotting. It is important for platelets to be able to stick to injured blood vessel walls. However, giant platelets are too big to stick properly. This means that clotting cannot happen properly.
Why do people with giant platelet disorders need blood transfusions?
In some cases, people with giant platelet disorders may need blood transfusions to treat injury-related hemorrhages or during surgeries.
What are the cells that help blood clot when cut?
They are characterized by abnormally large platelets, a low platelet count and abnormally increased bleeding or bruising. Platelets, also called thrombocytes, are tiny cell fragments. These circulate in the blood and help it to clot when flesh is cut or injured.
Can you take antiplatelet medication for giant platelet disorder?
People with giant platelet disorders should avoid anti-platelet medications. If they have a severe case of the disorder, they may need to moderate and alter their activities. For instance, patients may need to avoid contact sports.
