Understanding Bleeding Disorders

Bleeding disorders are a group of conditions that affect the body’s ability to form blood clots. Clotting is a complex process that involves proteins in the blood called clotting factors. When one or more of these factors are missing or not working properly, it can take longer for bleeding to stop.

Bleeding disorders can be inherited (passed down through families) or acquired later in life. They affect people of all ages, genders, and backgrounds.

Common Bleeding Disorders

Hemophilia A

Hemophilia A is caused by a deficiency or absence of clotting factor VIII. It is the most common type of hemophilia.

People with hemophilia A may experience:

Frequent or prolonged bleeding
Joint bleeds (especially knees, ankles, and elbows)
Easy bruising
Bleeding after surgery or injury

Hemophilia B

Hemophilia B is caused by low levels of clotting factor IX. It is less common than hemophilia A but presents with similar symptoms.

People with hemophilia B may experience:

Joint and muscle bleeds
Prolonged bleeding after injuries
Spontaneous bleeding episodes in more severe cases

Von Willebrand Disease (VWD)

Von Willebrand disease is the most common bleeding disorder and affects the blood’s ability to clot properly due to a problem with von Willebrand factor.

Common symptoms include:

Frequent nosebleeds
Easy bruising
Heavy or prolonged menstrual bleeding
Bleeding after dental work or surgery

VWD affects both men and women, though symptoms may be more noticeable in women.

Rare Bleeding Disorders

Rare bleeding disorders occur when other clotting factors (such as factors I, II, V, VII, X, XI, or XIII) are deficient.

Because they are less common, diagnosis may take longer. Symptoms can vary widely but may include:

Frequent nosebleeds
Bleeding into joints or muscles
Excessive bleeding after injury or surgery

Why Diagnosis Matters

Many people with bleeding disorders go undiagnosed or are diagnosed later in life. Proper diagnosis is important to:

Prevent complications
Manage bleeding episodes effectively
Plan safely for surgeries, dental work, or pregnancy

If you suspect a bleeding disorder, it’s important to speak with a hematologist—a doctor who specializes in blood disorders.

Living Well with a Bleeding Disorder

With the right care and treatment plan, people with bleeding disorders can live full, active lives. Treatment options may include:

Factor replacement therapy
Medications that help the body clot
Preventive (prophylactic) treatment plans

Support, education, and connection to a knowledgeable care team are key.
