Mar 24, 2022 · Thrombocythemia and thrombocytosis are conditions that occur when your blood has a higher-than-normal platelet count. Platelets are tiny blood cells. They are made in your bone marrow along with other kinds of blood cells. When you are injured, platelets stick together to form a plug that seals your wound. This plug is called a blood clot.

Platelets are parts of the blood that help form blood clots. Thrombocytosis (throm-boe-sie-TOE-sis) is a disorder in which your body produces too many platelets. It's called reactive thrombocytosis or secondary thrombocytosis when the cause is an underlying condition, such as an infection. Less commonly, when the high platelet count has no apparent...
People with high platelet levels often don't have signs or symptoms. When symptoms occur, they're often related to blood clots. Examples include: 1. Headache. 2. Confusion or changes in speech. 3. Chest pain. 4. Shortness of breath and nausea. 5. Weakness. 6. Burning pain in the hands or feet. Less commonly, very high platelet levels may cause blee...
Bone marrow is a spongy tissue inside your bones. It contains stem cells that can become red blood cells, white blood cells or platelets. Platelets stick together, helping blood to form a clot that stops bleeding when you damage a blood vessel, such as when you cut yourself. Thrombocytosis occurs when your body produces too many platelets.
Essential thrombocythemia can lead to a variety of potentially life-threatening complications, such as: 1. Strokes.If a blood clot occurs in the arteries that supply the brain, it may cause a stroke. A mini stroke, also called a transient ischemic attack, is a temporary interruption of blood flow to part of the brain. 2. Heart attacks.Less commonly...

May 11, 2024 · Thrombocytopenia and thrombocytosis are two conditions that affect the platelet count in the blood, but they have distinct differences in terms of underlying causes, platelet count ranges, and associated symptoms. Thrombocytopenia is characterized by a low platelet count, usually below 150,000 platelets per microliter of blood.
Sep 12, 2022 · Symptoms include: Headache. Bruising easily. Feeling weak, lightheaded or dizzy. Bleeding from your nose, mouth and gums. Bleeding in your stomach or intestinal tract.

Apr 19, 2022 · Thrombocytopenia signs and symptoms may include: Easy or excessive bruising (purpura) Superficial bleeding into the skin that appears as a rash of pinpoint-sized reddish-purple spots (petechiae), usually on the lower legs. Prolonged bleeding from cuts. Bleeding from your gums or nose. Blood in urine or stools.
Platelet disorders include. An abnormal increase in platelets (thrombocythemia and reactive thrombocytosis) A decrease in platelets (thrombocytopenia) Platelet dysfunction. Any of these conditions, even those in which platelets are markedly increased, may cause defective formation of hemostatic plugs and bleeding.
