Disseminated Intravascular Coagulation (DIC)
What is Disseminated Intravascular Coagulation (DIC)?
Disseminated Intravascular Coagulation, known as DIC, is a serious blood disorder where clotting happens too fast throughout the body. In DIC, your body uses up clotting factors and platelets faster than it can replace them. This leads to both dangerous blood clots in small vessels and severe bleeding because clotting resources are depleted.
DIC is not a disease on its own. It always happens as a complication of another serious medical condition. The disorder disrupts your body's normal balance between clot formation and clot breakdown. Small blood clots form in vessels throughout your body, blocking blood flow to organs. At the same time, bleeding can occur because the proteins and cells needed for clotting are used up.
DIC can develop quickly over hours or slowly over weeks or months. The acute form is a medical emergency that requires immediate hospital care. The chronic form develops more gradually and may be less severe. Both forms require treatment of the underlying condition causing DIC.
Symptoms
DIC symptoms vary depending on whether the condition is acute or chronic. Common signs include:
- Unexplained bleeding from the gums, nose, or injection sites
- Easy bruising or purple spots on the skin
- Blood in urine or stool
- Heavy menstrual bleeding
- Confusion or changes in mental status
- Fever
- Low blood pressure
- Shortness of breath
- Rapid heart rate
- Nausea and vomiting
Some people with chronic DIC may have mild symptoms or no obvious signs early on. Blood tests often detect the condition before symptoms become severe.

Causes and risk factors
DIC always occurs as a complication of another serious medical condition. Infections are the most common trigger, especially sepsis, which is a severe bloodstream infection. Cancer, particularly certain leukemias, can cause DIC. Severe trauma, major surgery, or burns can activate widespread clotting. Pregnancy complications like placental abruption or amniotic fluid embolism may trigger DIC. Severe allergic reactions, snake bites, and organ destruction from diseases like pancreatitis are other causes.
The underlying condition releases substances into the bloodstream that activate clotting throughout the body. This overwhelming activation exhausts your supply of clotting factors and platelets. Your risk increases if you have sepsis, cancer, are pregnant, or experience major trauma. Age and immune system health also play a role in how your body responds to these triggers.
How it's diagnosed
DIC is diagnosed through a combination of symptoms, medical history, and blood tests. Your doctor will look for signs of both clotting and bleeding. Blood tests measure clotting factors, platelets, and proteins involved in clot formation and breakdown. Low platelet count, low fibrinogen, prolonged PT and PTT times, and low antithrombin III levels suggest DIC. Testing protein C activity and prothrombin levels helps confirm the diagnosis.
Rite Aid offers testing for key biomarkers that help detect and monitor DIC. Our panel includes fibrinogen, PT/INR, partial thromboplastin time, platelet count, antithrombin III, protein C activity, and prothrombin levels. You can get tested at over 2,000 Quest Diagnostics locations nationwide. Early detection through blood testing allows for faster treatment of the underlying cause.
Treatment options
Treatment for DIC focuses on addressing the underlying condition causing the disorder. Common approaches include:
- Treating the root cause such as infection with antibiotics or removing cancerous tissue
- Blood transfusions to replace platelets and clotting factors
- Fresh frozen plasma to restore clotting proteins
- Platelet transfusions for severe bleeding
- Cryoprecipitate to replace fibrinogen
- Anticoagulant medications in some cases to prevent further clotting
- Supportive care in intensive care settings for acute DIC
- Monitoring blood tests regularly to track improvement
DIC is always a medical emergency that requires hospital care. There are no lifestyle changes that can treat active DIC. Prevention focuses on early treatment of infections, managing chronic conditions, and seeking immediate care for serious injuries or pregnancy complications.

Frequently asked questions
DIC is always caused by another serious medical condition, not by lifestyle factors. Sepsis is the most common trigger, accounting for about 30 to 50 percent of cases. Other causes include severe infections, certain cancers, major trauma, pregnancy complications, and organ damage. The underlying condition activates clotting throughout the body, leading to DIC.
Yes, DIC can be detected through specific blood tests that measure clotting function. Tests include platelet count, fibrinogen levels, PT/INR, PTT, antithrombin III, and protein C activity. Low platelets, low fibrinogen, prolonged clotting times, and decreased clotting proteins suggest DIC. Multiple test results together help confirm the diagnosis.
DIC is serious but not always fatal with prompt treatment. Survival depends on the underlying cause, how quickly treatment begins, and overall health. Acute DIC requires emergency care and has higher mortality rates. Chronic DIC may be managed more successfully. Early detection and treating the root cause improve outcomes significantly.
DIC can develop over hours in acute cases or over weeks to months in chronic cases. Acute DIC often follows sudden events like severe infections, major trauma, or pregnancy complications. Chronic DIC develops gradually, often in people with cancer or chronic inflammatory conditions. The speed depends on the underlying trigger and individual health factors.
Acute DIC develops rapidly and is a medical emergency with severe bleeding and clotting. It requires immediate intensive care treatment and has higher mortality. Chronic DIC develops slowly with milder symptoms that may not be obvious. Chronic cases often occur with cancer and may be managed with ongoing treatment of the underlying disease.
Lifestyle changes cannot directly prevent DIC because it results from other serious medical conditions. However, maintaining good health may reduce risks of triggers like infections. Seek immediate care for signs of severe infection, manage chronic diseases properly, and get regular medical checkups. Prevention focuses on early treatment of underlying conditions that could lead to DIC.
Platelets are blood cells that help form clots. In DIC, widespread clotting uses up platelets rapidly, causing counts to drop. A low platelet count, often below 100,000 per microliter, suggests DIC when combined with other abnormal clotting tests. This depletion of platelets leads to the bleeding problems seen in DIC.
Yes, pregnancy complications can trigger DIC. Conditions like placental abruption, amniotic fluid embolism, severe preeclampsia, and retained fetal tissue increase risk. DIC in pregnancy is a medical emergency requiring immediate delivery and intensive care. Proper prenatal care and quick treatment of pregnancy complications reduce this risk.
Testing frequency depends on your underlying condition and risk level. People with active cancer, chronic infections, or inflammatory conditions may need monthly or quarterly monitoring. Those recovering from acute illness may need weekly tests initially. Your doctor will create a testing schedule based on your specific situation and how your condition responds to treatment.
