Hypofibrinogenemia
What is Hypofibrinogenemia?
Hypofibrinogenemia is a rare bleeding disorder caused by lower than normal levels of fibrinogen in your blood. Fibrinogen is a protein made by your liver that helps your blood clot properly. When you do not have enough fibrinogen, your blood cannot form strong clots to stop bleeding.
This condition can be inherited from your parents or acquired later in life. The inherited form is genetic and passed down through families. The acquired form develops due to other health problems like liver disease, disseminated intravascular coagulation, or certain cancers. Both types increase your risk of abnormal bleeding.
People with hypofibrinogenemia may experience mild to severe bleeding problems. Some people have only minor symptoms while others face serious bleeding episodes. Early detection through blood testing helps you understand your risk and manage the condition before complications develop.
Symptoms
- Easy bruising that appears without injury
- Frequent nosebleeds that are hard to stop
- Heavy or prolonged menstrual bleeding
- Bleeding gums when brushing teeth
- Prolonged bleeding from minor cuts or injuries
- Blood in urine or stool
- Joint pain or swelling from internal bleeding
- Excessive bleeding after surgery or dental work
Some people with mild hypofibrinogenemia have no obvious symptoms until they experience surgery or injury. Regular blood testing can detect low fibrinogen levels before bleeding complications occur.

Causes and risk factors
Inherited hypofibrinogenemia is caused by genetic mutations that affect how your body makes fibrinogen. You inherit these mutations from one or both parents. If you inherit the mutation from one parent, you typically have lower fibrinogen levels but milder symptoms. Inheriting mutations from both parents causes more severe disease with very low fibrinogen.
Acquired hypofibrinogenemia develops when other health conditions reduce your fibrinogen levels. Liver disease prevents your liver from making enough fibrinogen. Disseminated intravascular coagulation uses up fibrinogen too quickly throughout your body. Some cancers and severe infections also lower fibrinogen levels. Certain medications and nutritional deficiencies can contribute to low fibrinogen as well.
How it's diagnosed
Doctors diagnose hypofibrinogenemia through specialized blood tests that measure fibrinogen levels in your blood. The Clauss fibrinogen test measures how well your fibrinogen functions in forming clots. Fibrinogen activity tests check how active your fibrinogen is during the clotting process. Fibrinogen antigen tests measure the total amount of fibrinogen protein in your blood.
Rite Aid offers fibrinogen testing as an add-on to our flagship blood panel. Testing at Quest Diagnostics locations makes it easy to check your fibrinogen levels regularly. Your doctor may also order genetic testing to determine if you have the inherited form. Early diagnosis helps you take steps to prevent bleeding complications and manage your condition.
Treatment options
- Fibrinogen replacement therapy through infusions during bleeding episodes or before surgery
- Cryoprecipitate transfusions to quickly raise fibrinogen levels
- Fresh frozen plasma for emergency treatment of severe bleeding
- Avoiding blood-thinning medications like aspirin and ibuprofen
- Gentle dental care to prevent gum bleeding
- Using electric razors instead of blades to prevent cuts
- Treating underlying conditions like liver disease that cause acquired forms
- Wearing medical alert jewelry to inform emergency responders
- Avoiding contact sports and high-risk activities that could cause injury
- Working with a hematologist who specializes in bleeding disorders

Frequently asked questions
Inherited hypofibrinogenemia is caused by genetic mutations you are born with that affect fibrinogen production. Acquired hypofibrinogenemia develops later in life due to other health conditions like liver disease, disseminated intravascular coagulation, or certain cancers. The inherited form runs in families, while the acquired form is triggered by other medical problems.
The severity depends on how low your fibrinogen levels are. Mild cases may cause easy bruising and occasional nosebleeds. Severe cases can lead to dangerous bleeding episodes, including internal bleeding, heavy bleeding after surgery, or life-threatening hemorrhage. Regular monitoring and proper treatment help most people manage the condition safely.
Inherited hypofibrinogenemia cannot be cured because it is caused by permanent genetic mutations. However, symptoms can be managed with fibrinogen replacement therapy and lifestyle changes. Acquired hypofibrinogenemia may improve if the underlying cause, such as liver disease, is treated successfully. Regular blood testing helps track your fibrinogen levels over time.
Normal fibrinogen levels typically range from 200 to 400 milligrams per deciliter. Hypofibrinogenemia is diagnosed when levels fall below 150 milligrams per deciliter. Levels below 100 significantly increase bleeding risk, while levels below 50 are considered severe and require immediate medical attention.
Testing frequency depends on the severity of your condition and whether it is inherited or acquired. People with inherited hypofibrinogenemia may need testing every 3 to 6 months. Those with acquired forms should test more frequently while treating the underlying cause. Your hematologist will create a testing schedule based on your specific situation.
Apply firm pressure to any bleeding wounds for at least 10 to 15 minutes. Seek immediate medical attention if bleeding does not stop, is severe, or occurs internally. Let emergency responders know you have a bleeding disorder. Your doctor may prescribe fibrinogen replacement therapy to keep at home for emergencies.
Pregnancy is possible but requires careful medical management. Low fibrinogen levels increase the risk of miscarriage, heavy bleeding during delivery, and postpartum hemorrhage. Work closely with a high-risk obstetrician and hematologist throughout pregnancy. Fibrinogen replacement therapy before and after delivery can reduce bleeding complications.
No specific diet directly raises fibrinogen levels. However, maintaining good liver health through a balanced diet supports fibrinogen production. Limit alcohol intake to protect your liver. Ensure adequate vitamin K intake to support overall blood clotting. Talk to your doctor about nutrition that supports your specific health needs.
Fibrinogen activity tests measure how well your fibrinogen functions in forming clots. Fibrinogen antigen tests measure the total amount of fibrinogen protein in your blood. Sometimes you have normal amounts of fibrinogen but it does not work properly. Testing both helps doctors understand exactly what type of fibrinogen problem you have.
While hypofibrinogenemia primarily causes bleeding problems, some rare cases can lead to abnormal clotting. This paradox happens when your body tries to compensate for low fibrinogen levels. Disseminated intravascular coagulation, which can cause hypofibrinogenemia, involves both excessive clotting and bleeding throughout the body. Your hematologist will monitor for both complications.
