Overview
DIC uses up clotting factors, so both clots and bleeding happen.
It's caused by severe illness like sepsis, major trauma, or pregnancy complications.
Symptoms
Common signs:
- Bleeding from many places
- Easy bruising
- Very sick
- Bruising easily or bleeding for a long time
Less common
- Purple spots
- Bleeding from IV sites
When to get medical care
Causes
Severe illness.
Does it spread or run in families?
- It isn't contagious. You can't catch it from someone else.
Who is more likely to get it
- People with sepsis: The most common cause
- People with severe injuries, cancer, or pregnancy problems: Higher risk
Possible complications
- Sudden kidney problem (acute kidney injury): From tiny clots
- Stroke: From clots or bleeding in the brain
Diagnosis
This is diagnosed in the emergency room or hospital.
The exam
A physical exam.
Tests
Tests, if needed:
- Clotting tests:
Treatment
Emergency care is needed. While waiting for help:
Self-care
- Emergency care
Which doctor treats this
- Emergency doctors treat it first, in the ER.
- They may send you to a hematologist (blood doctor).
Back to school, work, or sports
- Recovery time varies. Ask your care team when you can drive, lift, work, and exercise.
Children, pregnancy, and older adults
- Pregnancy: Can follow placental abruption.
Pregnancy and breastfeeding
- If you're pregnant or planning to be, tell your prenatal provider about this condition.
- This condition needs closer checkups during pregnancy. Plan ahead with your doctor.
- Don't start or stop any medicine on your own. Some are safe in pregnancy and some need to be changed.
- Ask before taking any pain reliever. The FDA advises avoiding ibuprofen and naproxen after 20 weeks unless your doctor says to.
- Breastfeeding: Most medicines are fine, but ask. The NIH LactMed database lists what's known about each one.
For caregivers
- Go to visits when you can and take notes.
- Keep a list of medicines, allergies, and doctors in one place.
- Learn the warning signs that need fast care.
- Learn CPR. Many hospitals and the Red Cross offer classes.
- Take breaks and ask for help. Caregivers need care too.
Outlook
Treating the cause is key.

Bring a list of your symptoms and medicines.
What to bring
- A list of your medicines and supplements
- Notes on when symptoms started and what makes them better or worse
Questions to ask
- What follow-up care do I need?
- How can I prevent this from happening again?
Research studies
Research studies test new ways to find and treat health problems. Some are looking for volunteers. Talk with your doctor before joining one.
