Bleeding Disorders: What You Need to Know About Hemophilia
What is Hemophilia and Why You Should Care?
Hemophilia is a rare but serious bleeding disorder that affects the blood’s ability to clot. This rare genetic bleeding disorder affects thousands of people worldwide, mostly males. While it may not be as well-known as other chronic conditions, hemophilia can significantly impair a person’s quality of life without proper management. Characterized by the body’s inability to form proper blood clots, this disorder can result in spontaneous bleeding, excessive bleeding from minor injuries, and internal hemorrhaging.
According to the Centers for Disease Control and Prevention (CDC), approximately 20,000 people in the United States are living with hemophilia, while more than 400,000 individuals worldwide are affected. Despite its rarity, understanding hemophilia is crucial—not only for those diagnosed but also for healthcare providers, caregivers, and the general public.

What Is Hemophilia?
Hemophilia is a genetic disorder in which the blood lacks enough clotting factor proteins to form clots normally. When someone with hemophilia gets a cut or internal injury, their blood doesn’t clot as quickly or efficiently, leading to prolonged bleeding or deep internal hemorrhaging.

“People with hemophilia have a deficiency or absence of clotting factors, which are proteins needed for blood to clot normally,” explains the World Federation of Hemophilia (WFH).
Blood clotting involves a cascade of 13 clotting factors. Hemophilia primarily affects Factor VIII (8) or Factor IX (9). When these are deficient or missing, the clotting process is disrupted.
Types of Hemophilia
There are two main types of hemophilia, categorized by which clotting factor is missing:
1. Hemophilia A
- Cause: Deficiency in Factor VIII
- Prevalence: Most common type (about 80–85% of cases)
- Also Known As: Classic Hemophilia
2. Hemophilia B
- Cause: Deficiency in Factor IX
- Prevalence: Less common (about 15% of cases)
- Also Known As: Christmas Disease
Other Rare Types
- Hemophilia C: Caused by a deficiency in Factor XI; more common among people of Ashkenazi Jewish descent.
- Acquired Hemophilia: A rare autoimmune disorder where the body develops antibodies against clotting factors, typically in adults.

Causes of Hemophilia
Hemophilia is most commonly an inherited X-linked recessive disorder, meaning the defective gene responsible for producing clotting factors is located on the X chromosome.
- Males (XY) are more likely to develop hemophilia because they have only one X chromosome.
- Females (XX) are typically carriers; they usually don’t show symptoms but can pass the gene to their children.
According to Mayo Clinic, “About two-thirds of people with hemophilia have a family history. One-third have no known family history and have the disorder due to a spontaneous gene mutation.”
Symptoms of Hemophilia
The signs and severity of hemophilia vary depending on the type and amount of clotting factor present.
Common Symptoms:
- Prolonged bleeding after injury or surgery
- Frequent nosebleeds
- Excessive bruising
- Blood in urine or stool
- Swelling and pain in joints (especially elbows, knees, and ankles)
- Intracranial bleeding (in severe cases)
In Infants and Children:
- Unexplained irritability
- Large bruises from minor bumps
- Bleeding after vaccinations or circumcision
- Prolonged bleeding from gums during teething
“Joint bleeding is one of the most serious complications of hemophilia, potentially leading to arthritis or permanent joint damage if not treated promptly,” notes the National Hemophilia Foundation (NHF).
Diagnosis of Hemophilia
Hemophilia is typically diagnosed via blood tests that measure clotting factor levels. Diagnosis can occur at different stages of life, including:
- At birth (especially if there’s a family history)
- During infancy or early childhood when symptoms first appear
- Prenatal testing in at-risk pregnancies through amniocentesis or chorionic villus sampling (CVS)
Diagnostic Tests Include:
- Activated Partial Thromboplastin Time (aPTT)
- Prothrombin Time (PT)
- Clotting factor assays (to determine specific factor deficiency)
- Genetic testing (for identifying mutations and for family planning)
Early diagnosis is crucial for managing the condition and avoiding complications.
Complications Associated with Hemophilia
Without proper treatment and monitoring, hemophilia can lead to serious health issues:
- Joint damage and arthritis due to repeated internal bleeding
- Intracranial hemorrhage, which can be fatal if untreated
- Inhibitors: The immune system may develop antibodies that attack replacement clotting factors
- Infections from plasma-derived factor concentrates (rare today due to screening)
- Delayed wound healing and post-surgical complications
According to the CDC, “The development of inhibitors is the most serious treatment-related complication of hemophilia.”
Treatment of Hemophilia
There is no universal cure for hemophilia yet, but effective treatments can control bleeding episodes and improve quality of life.
1. Replacement Therapy
The cornerstone of hemophilia treatment involves replacing the missing clotting factor with:
- Plasma-derived concentrates
- Recombinant factor concentrates (synthetic and safer)
Depending on the severity, treatment can be:
- On-demand: Administered during or after a bleeding episode
- Prophylactic (preventive): Regular infusions to prevent bleeding, especially in severe hemophilia
2. Non-factor Replacement Therapies
- Emicizumab (Hemlibra): A newer preventive treatment for Hemophilia A. It’s a monoclonal antibody that mimics Factor VIII’s function.
- Administered subcutaneously, it requires fewer infusions.
“Emicizumab has shown significant reduction in bleeding episodes in clinical trials,” notes the U.S. Food and Drug Administration (FDA).
3. Gene Therapy (Emerging Treatment)
Gene therapy aims to introduce a functional copy of the faulty gene into liver cells, enabling the production of clotting factors.
- Roctavian (valoctocogene roxaparvovec) became the first gene therapy approved in the EU for hemophilia A.
- Ongoing trials show promising results for long-term relief.
4. Desmopressin (DDAVP)
Used for mild Hemophilia A, this synthetic hormone increases the level of Factor VIII in the blood.
Living with Hemophilia: Lifestyle Tips and Precautions
1. Safe Physical Activity
Low-impact sports like swimming and cycling are recommended. Avoid contact sports that may cause joint or head injuries.
2. Joint Protection
Use protective gear and practice good posture. Physical therapy can help strengthen muscles and protect joints.
3. Avoid Certain Medications
Avoid blood-thinning drugs like aspirin or NSAIDs unless prescribed. Use acetaminophen (Tylenol) for pain.
4. Dental and Surgical Planning
Always inform dentists and surgeons about hemophilia in advance to plan for appropriate care.
5. Medical Alert Identification
Wearing a medical ID bracelet or necklace helps emergency personnel provide timely and accurate treatment.
6. Support and Education
Join hemophilia support groups through organizations like the NHF to share experiences, receive updates on research, and access community resources.
Prevention Strategies and Carrier Testing
Although hemophilia itself can’t be prevented in inherited cases, steps can be taken to reduce risks, these include:
- Genetic counseling for carriers and prospective parents
- Prenatal testing to identify hemophilia in fetuses
- Vaccination against hepatitis A and B to protect the liver
- Regular monitoring and early intervention to prevent joint damage
- Prompt treatment of minor injuries to avoid complications
“Early diagnosis, tailored treatment, and education can prevent 70% of complications from hemophilia,” according to the World Health Organization (WHO).
Frequently Asked Questions (FAQs)
Q1: Can females have hemophilia?
While this is rare, females can develop hemophilia if they inherit defective X chromosomes from both parents or have one faulty gene and lower-than-normal clotting factor levels.
Q2: Is hemophilia curable?
Currently, hemophilia is not curable, but gene therapy offers hope for long-term relief. Existing treatments allow most people to lead normal, active lives.
Q3: Can someone with hemophilia undergo surgery?
Yes, but it requires careful planning and replacement therapy to prevent excessive bleeding during and after surgery.
