Causes

Normal blood clotting involves as many as 20 different plasma proteins. These are known as blood clotting or coagulation factors. These factors interact with other chemicals to form a substance called fibrin that stops bleeding.

Problems can occur when certain coagulation factors are low or missing. Bleeding problems can range from mild to severe.

Some bleeding disorders are present at birth and are passed through families (inherited). Others develop from:

  • Illnesses such as vitamin K deficiency or severe liver disease
  • Treatments such as the use of drugs to stop blood clots (anticoagulants) or the long-term use of antibiotics

Bleeding disorders can also result from a problem with the number or function of the blood cells that promote blood clotting (platelets). These disorders can also be either inherited or develop later (acquired). The side effects of certain drugs often lead to the acquired forms.

Symptoms

  • ·   Bleeding into joints
  • ·   Excessive bruising
  • ·   Heavy bleeding
  • ·   Heavy menstrual bleeding
  • ·   Nosebleeds
  • ·   Excess bleeding with surgical procedures

The type of problems that occur depend on the specific bleeding disorder, and how severe it is.

Exams and Tests

Treatment

Treatment depends on the type of disorder. It may include:

  • Factor replacement
  • Fresh frozen plasma transfusion
  • Platelet transfusion
  • Other therapies

Outlook (Prognosis)

The outcome also depends on the disorder. Most primary bleeding disorders can be managed. When the disorders is due to diseases, such as DIC, the outcome will depend on how well the underlying disease can be treated.

Possible Complications

  • Bleeding in the brain
  • Severe bleeding (usually from the gastrointestinal tract or injuries)

Other complications can occur, depending on the disorder.

When to Contact a Medical Professional

Call your health care provider if you notice any unusual or severe bleeding.

Prevention

Prevention depends on the specific disorder.
