Platelet Disorders Symptoms
Chest pain or signs of stroke, including changes in your vision or speech or trouble walking, are medical emergencies. Call 9-1-1 right away.
If your platelet count is close to the healthy range, you may not have any symptoms. People often visit their healthcare providers when they start to get bruises for no reason or have heavy bleeding or bleeding that does not stop after a small injury.
Symptoms of a high platelet count
Symptoms of a high platelet count are mostly caused by a blood clot. Your symptoms may include:
- Chest pain and heart palpitations, difficulty breathing
- Dizziness, changes in your vision, weakness, numbness, slurred speech
- Extreme tiredness
- Headaches
- Pain and swelling of leg(s)
- Spleen or liver that is larger than normal
Bleeding can happen when you have a high platelet count and your platelets do not work normally. It can also happen when blood clots use up all your platelets. You may have nosebleeds, bleeding from your gums, and blood in your urine or stool. Blood in your stool may make your stool appear black.
Symptoms of a low platelet count
Symptoms of a low platelet count or platelets that do not work properly include:
- Bleeding from your gums, nosebleeds, or bleeding for a long time after a small injury
- Blood in your stool, urine, or vomit, or black stool or vomit that looks like coffee grounds
- Bruising easily
- Extreme tiredness
- Heavy menstrual periods
- Petechiae, which are small, flat red spots under the skin caused by blood leaking from blood vessels
- Purpura, which is bleeding under the skin that can cause red, purple, or brownish-yellow spots
- Weakness and confusion due to excessive blood loss and anemia
