	'''Fibrinogen deficiency''' is a rare [[blood disorder]] characterized by the absence or low levels of [[fibrinogen]], a protein essential for blood clot formation. This condition can lead to excessive bleeding or, in some cases, thrombosis. Fibrinogen deficiency can be inherited or acquired, with varying degrees of severity.

This condition can lead to excessive bleeding or, in some cases, thrombosis. Fibrinogen deficiency can be inherited or acquired, with varying degrees of severity.

	==Types==		==Types==
	Fibrinogen deficiency can be classified into three main types:		Fibrinogen deficiency can be classified into three main types:

	===Afibrinogenemia===		===Afibrinogenemia===
	Afibrinogenemia is a severe form of fibrinogen deficiency where there is a complete absence of fibrinogen in the blood. It is usually inherited in an [[autosomal recessive]] manner. Individuals with afibrinogenemia often experience spontaneous bleeding episodes, which can be life-threatening.

	===Hypofibrinogenemia===		===Hypofibrinogenemia===
	Hypofibrinogenemia is characterized by lower than normal levels of fibrinogen. The symptoms are generally milder compared to afibrinogenemia, but patients may still experience bleeding problems, especially during surgery or after trauma.		Hypofibrinogenemia is characterized by lower than normal levels of fibrinogen. The symptoms are generally milder compared to afibrinogenemia, but patients may still experience bleeding problems, especially during surgery or after trauma.

	===Dysfibrinogenemia===		===Dysfibrinogenemia===
	Dysfibrinogenemia occurs when fibrinogen is present but dysfunctional. This can lead to either bleeding or thrombotic complications, depending on the nature of the fibrinogen abnormality.		Dysfibrinogenemia occurs when fibrinogen is present but dysfunctional. This can lead to either bleeding or thrombotic complications, depending on the nature of the fibrinogen abnormality.

	==Causes==		==Causes==
	Fibrinogen deficiency is primarily caused by genetic mutations affecting the [[fibrinogen]] genes (FGA, FGB, and FGG). These mutations can lead to reduced production or abnormal function of fibrinogen. Acquired fibrinogen deficiency can result from liver disease, [[disseminated intravascular coagulation]] (DIC), or certain medications.

Line 28:		Line 38:
	* Heavy menstrual bleeding		* Heavy menstrual bleeding
	* Joint bleeding		* Joint bleeding

	==Diagnosis==		==Diagnosis==
	Diagnosis of fibrinogen deficiency involves blood tests to measure fibrinogen levels and assess clotting function. Genetic testing may be performed to identify specific mutations in the fibrinogen genes. Additional tests, such as liver function tests, may be conducted to rule out acquired causes.

	The prognosis for individuals with fibrinogen deficiency varies. With appropriate management, many patients can lead normal lives. However, severe cases, particularly afibrinogenemia, may require lifelong treatment and careful monitoring to prevent bleeding complications.
