What Are the Signs & Symptoms of Thrombocytopenia?
A child with a platelet count that is only a little low may not have any symptoms. But if the count drops low enough, a child might have one or more of these problems:
- easy bruising
- bleeding gums
- bleeding from minor wounds or nosebleeds that's hard to stop
- small red or purple spots on the skin called petechiae (peh-TEE-kee-eye)
- purple spots that look like bruises called purpura (PURR-pyur-ah)
- blood in vomit, urine (pee), or stool (poop)
The most serious type of bleeding that can happen is bleeding in the brain. Bleeding in or around the brain can't be seen, but it can cause headaches or changes in thinking or behavior.
What Causes Thrombocytopenia?
Many things can cause thrombocytopenia. Some are very serious and need medical treatment. Others are not serious and may clear up on their own with time.
Causes of thrombocytopenia include:
How Is Thrombocytopenia Diagnosed?
A doctor may suspect thrombocytopenia if a child has:
- easy bleeding
- red spots on the skin
The doctor will examine the child, ask questions, and order a blood test called a complete blood count (CBC).
If thrombocytopenia is diagnosed, more tests are done to figure out what's causing it. The tests needed depend on the child's medical history , the exam results, and what the blood test shows.
Sometimes, doctors order a biopsy to get a sample of bone marrow for testing and to check under a microscope.
How Is Thrombocytopenia Treated?
The treatment for thrombocytopenia depends on:
- what's causing it
- how low the platelet count is
- whether or not there is bleeding
Sometimes no treatment is needed and the thrombocytopenia clears up on its own. But some types need medical treatment to raise the platelet count to a safer level and to treat the underlying cause.
Thrombocytopenia is usually treated by a hematologist , a doctor who specializes in diagnosing and treating blood disorders.
What Else Should I Know?
Most of the time, thrombocytopenia either goes away on its own or can be treated successfully. But children with a low platelet count should take care to avoid injuries, especially to the head, because of the risk of bleeding.
If your child has thrombocytopenia, the doctor will tell you which activities are safe and which to avoid. Your child also shouldn't take medicines that contain ibuprofen (such as Motrin or Advil) or aspirin because these can increase the risk of bleeding.
