• #1 Hemophilia – Symptoms and causes – Mayo Clinic

  https://www.mayoclinic.org/diseases-conditions/hemophilia/symptoms-causes/syc-20373327

  Hemophilia is a rare disorder in which the blood doesn’t clot in the typical way because it doesn’t have enough blood-clotting proteins (clotting factors). If you have hemophilia, you might bleed for a longer time after an injury than you would if your blood clotted properly. […] If you have a severe form of the condition, the main concern is bleeding inside your body, especially in your knees, ankles and elbows. Internal bleeding can damage your organs and tissues and be life-threatening. […] Signs and symptoms of hemophilia vary, depending on your level of clotting factors. If your clotting-factor level is mildly reduced, you might bleed only after surgery or trauma. If your deficiency is severe, you can bleed easily for seemingly no reason. […] Signs and symptoms of spontaneous bleeding include: Unexplained and excessive bleeding from cuts or injuries, or after surgery or dental work; Many large or deep bruises; Unusual bleeding after vaccinations; Pain, swelling or tightness in your joints; Blood in your urine or stool; Nosebleeds without a known cause; In infants, unexplained irritability.

  https://www.cdc.gov/hemophilia/about/index.html

  Hemophilia is usually an inherited bleeding disorder in which blood does not clot properly. This can lead to spontaneous bleeding (bleeding that occurs for no known reason) as well as bleeding following injuries or surgery. […] The severity of hemophilia that a person has is determined by the amount of factor in the blood. The lower the amount of the factor, the more likely it is that bleeding will occur, which can lead to serious health problems. […] Hemophilia can result in bleeding within joints that can lead to chronic joint disease and pain; […] bleeding in the head and sometimes in the brain, which can cause long term problems, such as seizures and paralysis; and […] death, which can occur if the bleeding cannot be stopped or if it occurs in a vital organ such as the brain. […] Common signs of hemophilia include bleeding into the joints. This can cause swelling and pain or tightness in the joints; it often affects the knees, elbows, and ankles. […] Bleeding into the skin (which is bruising) or muscle and soft tissue causing a build-up of blood in the area (called a hematoma). […] Blood in the urine or stool. […] Frequent and hard-to-stop nosebleeds.

  https://www.bleeding.org/bleeding-disorders-a-z/types/hemophilia-b

  People with hemophilia B bleed longer than other people. Bleeds can occur internally, into joints and muscles, or externally, from minor cuts, dental procedures or trauma. How frequently a person bleeds and how serious the bleeds are depends on how much FIX is in the plasma, the straw-colored fluid portion of blood. […] Normal plasma levels of FIX range from 50% to 150%. Levels below 50%, or half of what is needed to form a clot, determine a persons symptoms. […] Mild hemophilia B. 6% up to 49% of FIX in the blood. People with mild hemophilia B typically experience bleeding only after serious injury, trauma or surgery. In many cases, mild hemophilia is not diagnosed until an injury, surgery or tooth extraction results in prolonged bleeding. The first episode may not occur until adulthood. Women with mild hemophilia often experience menorrhagia, heavy menstrual periods, and can hemorrhage after childbirth.

  Classic hemophilia (Hemophilia A and B) primarily affects males and is hereditary, transmitted from one generation to another. […] Individuals with hemophilia have excessive bleeding after injuries or spontaneous bleeding episodes because of the lack of a specific coagulation factor in their blood. […] The most well-known bleeding disorder is Hemophilia A, caused by a lack of the coagulation factor VIII (approximately 80 percent of hemophilia cases). […] Hemophilia B (also known as Christmas disease) is caused by the lack of the coagulation factor IX (20 percent of hemophilia cases). […] Both factor VIII and IX deficiencies occur in mild, moderate and severe forms depending on the level of the missing coagulation factor. […] Mild — 6 percent to 49 percent —– excessive bleeding after surgery, dental work, or trauma Moderate — 2 percent to 5 percent —– excessive bleeding after surgery, dental work, trauma, and rarely spontaneous bleeding Severe — Less than 1 percent —– bleeding spontaneously, joint injury, intracranial and internal bleeding.

  Hemophilia is an inherited bleeding disorder. People with hemophilia bleed easily because they dont have enough of one of the clotting factors in their blood. Clotting factors are needed for blood to clot. Blood clots to prevent excessive bleeding. […] The severity of hemophilia depends on the amount of clotting factors in the blood. Those affected with hemophilia who have blood clotting factor levels greater than 5% most often have bleeding only with serious injury, major surgeries, or tooth extractions. These people may not even be diagnosed until bleeding complications from a surgery occur. […] Severe hemophilia is when the factor VIII or IX levels are less than 1%. Bleeding can occur even with minimal activities of daily life. Bleeding may also occur from no known injury. Bleeding most often occurs in the joints, muscles, and in the head.

  The most common symptom of this disorder is heavy, uncontrollable bleeding. Bleeding can be external (cuts, nosebleeds) or internal (bruises, joint bleeds). […] Symptoms may include: Bruising. Bruises can occur from even small accidents. This can result in a large buildup of blood under the skin causing swelling (hematoma). […] Easy bleeding. A tendency to bleed from the nose, mouth, and gums with minor injury. Bleeding while brushing and flossing teeth or having dental work is often a sign of hemophilia. […] Bleeding into a joint (hemarthrosis). This can cause pain, immobility, and deformity if not treated. This is the most common site of complications due to hemophilia bleeding. […] Bleeding into the muscles. Bleeding into the muscles can cause swelling, pain, and redness. […] Bleeding in the brain. This can happen from injury or on its own. Bleeding from injury, or spontaneously in the brain, is the most serious bleeding complication and can be life-threatening.

  People who have factor VIII levels between 1% and 5% have moderate hemophilia A and moderate symptoms. Moderate hemophilia A symptoms typically surface when children are toddlers. They may have the following symptoms: Bruising: They bruise very easily. Unusual bleeding: If they have surgery, have an injury that causes bleeding or have a tooth pulled, they’ll bleed more than normal and for a longer time than expected. Spontaneous bleeding: Rarely, they’ll begin to bleed for no apparent reason. […] People who have less than 1% of factor VIII in their blood have severe hemophilia A and severe symptoms. Many times, hemophilia A symptoms appear as children are being born or, in the case of male babies, when they’re being circumcised. Other times, children develop symptoms a few months after they’re born. Common symptoms include: Bleeding: Babies and toddlers may bleed from their mouths after minor injuries, like bumping their mouths on a toy. Swollen lumps on their heads: Babies and toddlers who bump their heads often develop goose eggs large round lumps on their heads. Fussiness, irritability or refusing to crawl or walk: These symptoms may happen if babies and toddlers have internal bleeding into a muscle or joint. They may have areas on their bodies that look bruised and swollen, feel warm to your touch or cause pain when you gently touch the area. Hematomas: A hematoma is a mass of congealed blood that gathers under babies or toddlers skin. Babies and toddlers may develop hematomas after receiving an injection.

The joint feels a little puffy to the touch. […] As the hours pass, the joint becomes hot to the touch. Fully flexing or extending the joint becomes painful. Weight bearing becomes difficult. By this time, the joint is visibly swollen. […] As the bleeding continues and the swelling increases, all movement in the joint is lost. The joint becomes fixed in a slightly flexed position in an attempt to relieve the interior pressure in the joint. The pain at this point can be excruciating.

  https://hemophilianewstoday.com/symptoms-hemophilia/

  Bleeding in the brain, also called intracranial bleeding or intracranial hemorrhage, is a leading cause of death in hemophilia. Up to about 20% of brain bleeds in hemophilia patients may be fatal, though the risk of lethal bleeds has decreased in recent years as new treatments have become available. […] Brain bleeding is more common in people with severe hemophilia than in those with milder forms of the disease. Another major risk factor for brain bleeding in hemophilia is age, with this type of bleeding being more commonly seen in children younger than 2, and in adults older than 60. […] Recurrent joint bleeds can lead to a condition marked by permanent and irreversible joint damage. Called hemophilic arthropathy, this condition is characterized by pain and reduced mobility in the affected joint(s). […] Chronic pain, especially ongoing pain affecting joints where bleeds have occurred, is common in hemophilia. In fact, as many as two-thirds of patients with severe hemophilia report experiencing daily joint pain.

• #42 Haemophilia – Wikipedia

  https://en.wikipedia.org/wiki/Haemophilia

  Internal bleeding is common in people with severe haemophilia and some individuals with moderate haemophilia. […] The most characteristic type of internal bleed is a joint bleed where blood enters into the joint spaces. […] If not treated promptly, joint bleeds can lead to permanent joint damage and disfigurement. […] Children with mild to moderate haemophilia may not have any signs or symptoms at birth, especially if they do not undergo circumcision. […] Their first symptoms are often frequent and large bruises and haematomas from frequent bumps and falls as they learn to walk. […] Swelling and bruising from bleeding in the joints, soft tissue, and muscles may also occur. […] Children with mild haemophilia may not have noticeable symptoms for many years. […] Often, the first sign in very mild haemophiliacs is heavy bleeding from a dental procedure, an accident, or surgery.

  https://hemophilianewstoday.com/symptoms-hemophilia/

  A hallmark sign of hemophilia, especially in more severe cases, is bleeding into the joints, also known as hemarthrosis. This most commonly affects the knees, elbows, ankles, shoulders, wrist, and/or hips. Joint bleeds are more common in older individuals and people who are more physically active. These bleeds may cause joints to swell and become stiffer, impairing patients’ mobility and causing pain. […] Individuals with hemophilia also may experience bleeding in internal organs, such as the liver, spleen, and kidneys. This can result in symptoms like abdominal pain, swelling in the abdomen, abnormal rigidity or tenderness in the abdomen, blood in the stool, which may appear reddish or cause stool to be unusually dark and sticky, blood in urine, known as hematuria, and vomiting blood, called hematemesis.

  The most serious type of bleeding in hemophilia is generally considered to be bleeding in the brain. […] Recurrent bleeding in the joints can lead to a condition called hemophilic arthropathy, which is marked by permanent and irreversible joint damage, joint pain, and limited mobility. […] Bleeds in large muscles can cause serious blood loss, while bleeding into confined muscles like those in the forearms and calves can cause a painful condition called compartment syndrome due to increased pressure in and around muscles. Muscle bleeds also can put pressure on nerves, leading to symptoms like numbness and tingling. […] People with hemophilia are at higher risk of having low bone mineral density, which can set the stage for conditions like osteoporosis to develop. In osteoporosis, bones become weaker and more prone to break, or fracture.

  The most common symptom of this disorder is heavy, uncontrollable bleeding. Bleeding can be external (cuts, nosebleeds) or internal (bruises, joint bleeds). […] Symptoms may include: Bruising. Bruises can occur from even small accidents. This can result in a large buildup of blood under the skin causing swelling (hematoma). […] Easy bleeding. A tendency to bleed from the nose, mouth, and gums with minor injury. Bleeding while brushing and flossing teeth or having dental work is often a sign of hemophilia. […] Bleeding into a joint (hemarthrosis). This can cause pain, immobility, and deformity if not treated. This is the most common site of complications due to hemophilia bleeding. […] Bleeding into the muscles. Bleeding into the muscles can cause swelling, pain, and redness. […] Bleeding in the brain. This can happen from injury or on its own. Bleeding from injury, or spontaneously in the brain, is the most serious bleeding complication and can be life-threatening.

  People with bleeding disorders can have minor cuts that dont clot, or the bleeding stops and begins again. […] They can also have spontaneous nosebleeds that can be recurrent and heavy. […] The most frequent sites for internal bleeds are the joints, usually the knee, ankle, elbow, and hip joints. […] At first, the joint may be described as tingly or bubbly. […] As blood begins to pool, the joint may feel tight, maybe warm or hot to the touch, and can become painful, especially when bending. […] Repetitive joint bleeds can cause irreversible damage to the joint. […] Once you have had one bleed in a joint, you are more likely to develop future bleeds in the same joint. […] Muscle bleeds can be extremely painful, and numbness and pale skin may be noted over the injured muscle. […] If left untreated, this can lead to nerve damage.

  Bleeding in a muscle can cause pain, swelling, warmth, and a bruise over the area. […] Babies and toddlers who have bleeding in a muscle or joint might be fussy or refuse to crawl or walk. […] Bleeding in the digestive system can cause black or bloody poop or blood in throw-up (vomit). […] Bleeding in the brain can cause a headache, vomiting, sleepiness, or seizures. […] Hemophilia can be mild, moderate, or severe, based on the amount of the clotting factor in the blood. The lower the level of the clotting factor, the more likely the person is to have bleeding. […] Few babies are diagnosed with hemophilia in the first 6 months of life. That’s because they’re unlikely to have an injury that would lead to bleeding. Bleeding may happen after a circumcision, which can lead to the diagnosis. […] As kids get older and more active, a doctor might suspect hemophilia if a child bruises easily and bleeds too much when injured.

  Examples of having a bleeding tendency or symptoms in females may include: Bruising easily […] Heavy and/or long periods. This is called heavy menstrual bleeding or sometimes abnormal uterine bleeding or menorrhagia. It can lead to low iron levels or anaemia […] Bleeding or oozing for a long time after dental surgery or extractions, other surgery and medical procedures, injuries or accidents […] Heavy bleeding for extended time after childbirth (particularly with delayed or late postpartum haemorrhage) […] Females with very low clotting factor levels may also have internal bleeding into joints, muscles, organs and soft tissues. […] Heavy menstrual bleeding can lead to anaemia (low red blood cell count/low blood iron levels), with symptoms of fatigue, paleness, lack of energy and shortness of breath. […] Although these can be symptoms related to haemophilia, they can also be symptoms of a gynaecological disorder, so it is important to consult a gynaecologist.

  In cases of severe hemophilia, patients often present with internal bleeding, potentially impacting multiple organs. Joints can become painful, swollen, inflamed, and warm and have a restricted range of motion due to bleeding. The most commonly affected joints are the knees, elbows, ankles, shoulders, wrists, and hips. Spontaneous joint bleed incidence typically increases with age, reaching up to 60% by 65 years of age. Repetitive joint bleeds often lead to hemophilic arthropathies. […] The hallmark clinical presentation of both hemophilia A and B is joint (hemarthroses) and muscle bleeding, which typically presents in severe disease. Around 50% of patients with severe hemophilia will have a muscle bleed or hematoma by age 6 to 8 months and can present with compartment syndrome. The most dreadful life-threatening bleeding complications are intracranial bleeding, which is the leading cause of death in patients with hemophilia, iliopsoas muscle bleeds due to significant volume loss, and risk for hypovolemic shock, retropharyngeal bleeding, and airway compromise.

• #71 About Hemophilia | Hemophilia | CDC

  https://www.cdc.gov/hemophilia/about/index.html

  Hemophilia is usually an inherited bleeding disorder in which blood does not clot properly. This can lead to spontaneous bleeding (bleeding that occurs for no known reason) as well as bleeding following injuries or surgery. […] The severity of hemophilia that a person has is determined by the amount of factor in the blood. The lower the amount of the factor, the more likely it is that bleeding will occur, which can lead to serious health problems. […] Hemophilia can result in bleeding within joints that can lead to chronic joint disease and pain; […] bleeding in the head and sometimes in the brain, which can cause long term problems, such as seizures and paralysis; and […] death, which can occur if the bleeding cannot be stopped or if it occurs in a vital organ such as the brain. […] Common signs of hemophilia include bleeding into the joints. This can cause swelling and pain or tightness in the joints; it often affects the knees, elbows, and ankles. […] Bleeding into the skin (which is bruising) or muscle and soft tissue causing a build-up of blood in the area (called a hematoma). […] Blood in the urine or stool. […] Frequent and hard-to-stop nosebleeds.

  https://hemophilianewstoday.com/what-is-hemophilia/

  The most serious type of bleeding in hemophilia is generally considered to be bleeding in the brain. […] Recurrent bleeding in the joints can lead to a condition called hemophilic arthropathy, which is marked by permanent and irreversible joint damage, joint pain, and limited mobility. […] Bleeds in large muscles can cause serious blood loss, while bleeding into confined muscles like those in the forearms and calves can cause a painful condition called compartment syndrome due to increased pressure in and around muscles. Muscle bleeds also can put pressure on nerves, leading to symptoms like numbness and tingling. […] People with hemophilia are at higher risk of having low bone mineral density, which can set the stage for conditions like osteoporosis to develop. In osteoporosis, bones become weaker and more prone to break, or fracture.

  A hallmark sign of hemophilia, especially in more severe cases, is bleeding into the joints, also known as hemarthrosis. This most commonly affects the knees, elbows, ankles, shoulders, wrist, and/or hips. Joint bleeds are more common in older individuals and people who are more physically active. These bleeds may cause joints to swell and become stiffer, impairing patients’ mobility and causing pain. […] Individuals with hemophilia also may experience bleeding in internal organs, such as the liver, spleen, and kidneys. This can result in symptoms like abdominal pain, swelling in the abdomen, abnormal rigidity or tenderness in the abdomen, blood in the stool, which may appear reddish or cause stool to be unusually dark and sticky, blood in urine, known as hematuria, and vomiting blood, called hematemesis.

  People who have factor VIII levels between 1% and 5% have moderate hemophilia A and moderate symptoms. Moderate hemophilia A symptoms typically surface when children are toddlers. They may have the following symptoms: Bruising: They bruise very easily. Unusual bleeding: If they have surgery, have an injury that causes bleeding or have a tooth pulled, they’ll bleed more than normal and for a longer time than expected. Spontaneous bleeding: Rarely, they’ll begin to bleed for no apparent reason. […] People who have less than 1% of factor VIII in their blood have severe hemophilia A and severe symptoms. Many times, hemophilia A symptoms appear as children are being born or, in the case of male babies, when they’re being circumcised. Other times, children develop symptoms a few months after they’re born. Common symptoms include: Bleeding: Babies and toddlers may bleed from their mouths after minor injuries, like bumping their mouths on a toy. Swollen lumps on their heads: Babies and toddlers who bump their heads often develop goose eggs large round lumps on their heads. Fussiness, irritability or refusing to crawl or walk: These symptoms may happen if babies and toddlers have internal bleeding into a muscle or joint. They may have areas on their bodies that look bruised and swollen, feel warm to your touch or cause pain when you gently touch the area. Hematomas: A hematoma is a mass of congealed blood that gathers under babies or toddlers skin. Babies and toddlers may develop hematomas after receiving an injection. Breathing difficulties: Sometimes, bleeding may cause your child’s tongue to swell so much that it blocks their airway.

[…] Bleeding in the digestive system can cause black or bloody poop or blood in throw-up (vomit). […] Bleeding in the brain can cause a headache, vomiting, sleepiness, or seizures. […] Hemophilia can be mild, moderate, or severe, based on the amount of the clotting factor in the blood. The lower the level of the clotting factor, the more likely the person is to have bleeding. […] Few babies are diagnosed with hemophilia in the first 6 months of life. That’s because they’re unlikely to have an injury that would lead to bleeding. Bleeding may happen after a circumcision, which can lead to the diagnosis. […] As kids get older and more active, a doctor might suspect hemophilia if a child bruises easily and bleeds too much when injured.

  Severe hemophilia often manifests in the first months of life, whereas mild or moderate hemophilia will present later in childhood or adolescence, often incidentally or following trauma. […] Characteristic hemophilia bleeding symptoms can manifest as spontaneous intracranial bleeding in neonates, excessive postoperative bleeding after circumcision, atraumatic painful hemarthrosis, inexplicable bruising when the infant begins crawling or walking, and inordinate musculocutaneous hemorrhage, either spontaneously or after intramuscular vaccination. […] Hemarthrosis manifests as the most common hemorrhagic symptom in adolescents and adults. Recurrent hemarthrosis eventually causes erosion of joint cartilage and results in the painful Charcot joints of hemophilic arthropathy. Intracranial hemorrhage represents the most immediate life-threatening manifestation of hemophilia A with the potential for chronic neurological disability and long-term neurological sequelae.

  The most common symptom of this disorder is heavy, uncontrollable bleeding. Bleeding can be external (cuts, nosebleeds) or internal (bruises, joint bleeds). […] The severity of hemophilia depends on the amount of clotting factors in the blood. Those affected with hemophilia who have blood clotting factor levels greater than 5% most often have bleeding only with serious injury, major surgeries, or tooth extractions. These people may not even be diagnosed until bleeding complications from a surgery occur. […] Severe hemophilia is when the factor VIII or IX levels are less than 1%. Bleeding can occur even with minimal activities of daily life. Bleeding may also occur from no known injury. Bleeding most often occurs in the joints, muscles, and in the head. […] Symptoms may include: Bruising. Bruises can occur from even small accidents. This can result in a large buildup of blood under the skin causing swelling (hematoma).

Up to about 20% of brain bleeds in hemophilia patients may be fatal, though the risk of lethal bleeds has decreased in recent years as new treatments have become available. […] Brain bleeding is more common in people with severe hemophilia than in those with milder forms of the disease. Another major risk factor for brain bleeding in hemophilia is age, with this type of bleeding being more commonly seen in children younger than 2, and in adults older than 60. […] Recurrent joint bleeds can lead to a condition marked by permanent and irreversible joint damage. Called hemophilic arthropathy, this condition is characterized by pain and reduced mobility in the affected joint(s). […] Chronic pain, especially ongoing pain affecting joints where bleeds have occurred, is common in hemophilia. In fact, as many as two-thirds of patients with severe hemophilia report experiencing daily joint pain.

  During a bleed, the affected limb or body part may feel painful, warm, tight, and swollen. Over time, bleeds may gradually cause damage to joints that contribute to chronic pain. Some people with bleeding disorders also report frequent headaches. […] Bleeding can gradually damage joints to the point where movement is difficult and the joint becomes deformed. Approximately 57 percent of those surveyed by MyHemophiliaTeam said that difficulty walking and other mobility issues impeded their day-to-day routines. Joint damage can become severe enough that some people with bleeding disorders need surgery to repair or replace a joint. […] The results of the MyHemophiliaTeam survey revealed that 65 percent of those with hemophilia report depression severe enough to affect their daily life. Many people with bleeding disorders also report experiencing fatigue and anxiety. Depression, anxiety, and fatigue are common symptoms for many people with chronic illnesses.

  People with hemophilia B bleed longer than other people. Bleeds can occur internally, into joints and muscles, or externally, from minor cuts, dental procedures or trauma. How frequently a person bleeds and how serious the bleeds are depends on how much FIX is in the plasma, the straw-colored fluid portion of blood. […] Normal plasma levels of FIX range from 50% to 150%. Levels below 50%, or half of what is needed to form a clot, determine a persons symptoms. […] Mild hemophilia B. 6% up to 49% of FIX in the blood. People with mild hemophilia B typically experience bleeding only after serious injury, trauma or surgery. In many cases, mild hemophilia is not diagnosed until an injury, surgery or tooth extraction results in prolonged bleeding. The first episode may not occur until adulthood. Women with mild hemophilia often experience menorrhagia, heavy menstrual periods, and can hemorrhage after childbirth.

  Examples of having a bleeding tendency or symptoms in females may include: Bruising easily […] Heavy and/or long periods. This is called heavy menstrual bleeding or sometimes abnormal uterine bleeding or menorrhagia. It can lead to low iron levels or anaemia […] Bleeding or oozing for a long time after dental surgery or extractions, other surgery and medical procedures, injuries or accidents […] Heavy bleeding for extended time after childbirth (particularly with delayed or late postpartum haemorrhage) […] Females with very low clotting factor levels may also have internal bleeding into joints, muscles, organs and soft tissues. […] Heavy menstrual bleeding can lead to anaemia (low red blood cell count/low blood iron levels), with symptoms of fatigue, paleness, lack of energy and shortness of breath. […] Although these can be symptoms related to haemophilia, they can also be symptoms of a gynaecological disorder, so it is important to consult a gynaecologist.

  Factor levels of 1% to 5% of normal are indicative of moderate hemophilia. These patients may have abnormal bleeding after minor trauma but should not experience spontaneous bleeding. However, after repeated bleeding into the same joint, spontaneous bleeding may occur in that joint, even if the individual has moderate hemophilia. […] Persons with 6% to 49% of factor activity are considered to have mild hemophilia and are expected to have relatively few problems with bleeding, except during surgery or after severe trauma. Carrier women can have lower than normal plasma levels of factor VIII or IX and thus can experience symptoms of mild hemophilia. […] Joint damage (hemophilia arthropathy) is the most common complication of bleeding in hemophilia. Prophylaxis has been shown to reduce joint bleeding and prevent joint damage. Early treatment of each joint bleed reduces the risk of chronic joint disease, functional impairment, and disability. […] The frequency of joint disease has been further reduced as increasing numbers of individuals with severe hemophilia have participated in prophylactic programs. Unfortunately, most of these patients still develop at least one chronic joint in their lifetimes.

  https://www.cdc.gov/hemophilia/about/index.html

  Hemophilia is usually an inherited bleeding disorder in which blood does not clot properly. This can lead to spontaneous bleeding (bleeding that occurs for no known reason) as well as bleeding following injuries or surgery. […] The severity of hemophilia that a person has is determined by the amount of factor in the blood. The lower the amount of the factor, the more likely it is that bleeding will occur, which can lead to serious health problems. […] Hemophilia can result in bleeding within joints that can lead to chronic joint disease and pain; […] bleeding in the head and sometimes in the brain, which can cause long term problems, such as seizures and paralysis; and […] death, which can occur if the bleeding cannot be stopped or if it occurs in a vital organ such as the brain. […] Common signs of hemophilia include bleeding into the joints. This can cause swelling and pain or tightness in the joints; it often affects the knees, elbows, and ankles. […] Bleeding into the skin (which is bruising) or muscle and soft tissue causing a build-up of blood in the area (called a hematoma). […] Blood in the urine or stool.
