Abnormal Bleeding or Bruising

When your body struggles to control bleeding or develops bruises without clear cause, it signals that something might be affecting your blood's ability to clot properly. Abnormal bleeding and bruising encompass a range of conditions where the normal process of blood clotting either happens too slowly, doesn't happen at all, or breaks down too quickly. These bleeding disorders can range from mild inconveniences to serious medical conditions requiring ongoing management.

Symptoms

Common signs and symptoms of Abnormal Bleeding or Bruising include:

Frequent nosebleeds that are hard to stop
Easy bruising from minor bumps or without injury
Heavy or prolonged menstrual periods
Bleeding gums during brushing or eating
Blood in urine or stool
Excessive bleeding after cuts or dental work
Large or painful bruises that appear suddenly
Bleeding into joints causing pain and swelling
Tiny red or purple spots on skin (petechiae)
Prolonged bleeding after surgery or injury
Bleeding under the skin in unusual patterns
Weakness or fatigue from blood loss

When to see a doctor

If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.

Causes & Risk Factors

Several factors can contribute to Abnormal Bleeding or Bruising.

The root of abnormal bleeding and bruising lies in problems with your body's complex clotting system, which involves blood cells called platelets and proteins called clotting factors working together like a well-orchestrated repair crew.

The root of abnormal bleeding and bruising lies in problems with your body's complex clotting system, which involves blood cells called platelets and proteins called clotting factors working together like a well-orchestrated repair crew. When you get a cut, platelets rush to the scene and stick together to form a plug, while clotting factors create a mesh of fibrin to strengthen the clot. If any part of this system malfunctions, bleeding can continue longer than it should or bruises can form more easily than normal.

Some bleeding disorders are inherited, passed down through families in genes that control how clotting factors are made.

Some bleeding disorders are inherited, passed down through families in genes that control how clotting factors are made. Hemophilia A and B are the most well-known inherited bleeding disorders, caused by missing or defective clotting factors VIII and IX respectively. Von Willebrand disease, the most common inherited bleeding disorder, affects a protein that helps platelets stick together and protects clotting factor VIII.

Acquired bleeding problems can develop later in life due to various factors including liver disease (since the liver makes most clotting factors), certain medications like blood thinners or aspirin, autoimmune conditions where the body attacks its own clotting system, vitamin K deficiency, kidney disease, or bone marrow disorders that affect platelet production.

Sometimes infections, cancer treatments, or other serious illnesses can temporarily disrupt normal clotting function.

Risk Factors

  • Family history of bleeding disorders
  • Taking blood-thinning medications like warfarin or aspirin
  • Liver disease or dysfunction
  • Kidney disease or kidney failure
  • Autoimmune disorders like lupus
  • Vitamin K deficiency or malnutrition
  • Cancer or cancer treatments like chemotherapy
  • Bone marrow disorders or blood cancers
  • Heavy alcohol use over time
  • Certain infections that affect clotting

Diagnosis

How healthcare professionals diagnose Abnormal Bleeding or Bruising:

  • 1

    Diagnosing bleeding disorders typically starts with a detailed conversation about your bleeding history, including questions about how long cuts take to stop bleeding, whether you bruise easily, family history of bleeding problems, and any medications you take.

    Diagnosing bleeding disorders typically starts with a detailed conversation about your bleeding history, including questions about how long cuts take to stop bleeding, whether you bruise easily, family history of bleeding problems, and any medications you take. Your doctor will also perform a physical examination looking for signs of abnormal bleeding or bruising patterns, enlarged organs, or other clues that might point to an underlying condition.

  • 2

    Blood tests form the cornerstone of diagnosis and usually begin with basic screening tests including a complete blood count to check platelet levels, prothrombin time (PT) and activated partial thromboplastin time (aPTT) to measure how long it takes your blood to clot, and sometimes a bleeding time test.

If these initial tests suggest a problem, more specific tests can identify exactly which part of the clotting system isn't working properly, such as factor assays to measure individual clotting factor levels or tests for von Willebrand factor.

    Additional testing might include liver function tests, kidney function tests, vitamin levels, or tests for autoimmune conditions depending on what the initial evaluation suggests.

    Additional testing might include liver function tests, kidney function tests, vitamin levels, or tests for autoimmune conditions depending on what the initial evaluation suggests. In some cases, doctors might recommend genetic testing, especially if there's a strong family history of bleeding disorders. Bone marrow biopsy is rarely needed but might be considered if there are concerns about blood cell production.

Complications

  • The complications of abnormal bleeding and bruising range from minor inconveniences to life-threatening emergencies, largely depending on the severity of the underlying disorder and how well it's managed.
  • Chronic blood loss, even if it seems minor, can lead to iron deficiency anemia, causing fatigue, weakness, and reduced quality of life that gradually worsens over time.
  • More serious bleeding episodes can occur in critical areas like the brain (intracranial hemorrhage), which represents a medical emergency requiring immediate intervention to prevent permanent neurological damage or death.
  • Joint bleeding, particularly common in hemophilia, can cause long-term joint damage, chronic pain, and reduced mobility if not properly treated.
  • Repeated bleeding into the same joint can lead to arthritis-like changes that significantly impact daily activities and quality of life.
  • Muscle bleeding can also cause complications, potentially leading to compartment syndrome where pressure builds up within muscle compartments, threatening blood supply to surrounding tissues.
  • Without proper management and access to treatment, people with severe bleeding disorders may develop chronic disabilities that affect their ability to work, exercise, or participate in normal activities.

Prevention

  • While inherited bleeding disorders cannot be prevented, many acquired bleeding problems can be avoided or minimized through careful attention to medications, diet, and overall health.
  • People taking blood-thinning medications should work closely with their healthcare providers to maintain the right balance between preventing clots and avoiding excessive bleeding, which often involves regular monitoring and dose adjustments.
  • Avoiding unnecessary medications that interfere with clotting, such as aspirin or NSAIDs, unless specifically recommended by a doctor can help reduce bleeding risk.
  • Maintaining good overall health supports proper clotting function in several ways.
  • Eating a balanced diet ensures adequate vitamin K intake, which is essential for making several clotting factors, while limiting alcohol consumption protects liver function since the liver produces most clotting proteins.
  • Regular medical care helps detect and treat conditions like liver disease, kidney disease, or autoimmune disorders before they significantly impact clotting function.
  • For people with known bleeding disorders, prevention strategies focus on avoiding injuries and preparing for situations where bleeding might occur.
  • This includes using protective gear during sports or physical activities, maintaining good dental hygiene to prevent gum disease and bleeding, and having a clear action plan for managing bleeding episodes.
  • Genetic counseling can help families understand inheritance patterns and make informed decisions about family planning.

Treatment approaches vary dramatically depending on the specific type and severity of the bleeding disorder, ranging from simple lifestyle modifications to regular infusions of clotting factors.

Treatment approaches vary dramatically depending on the specific type and severity of the bleeding disorder, ranging from simple lifestyle modifications to regular infusions of clotting factors. For inherited bleeding disorders like hemophilia, treatment often involves replacing the missing clotting factors through intravenous infusions, either on a regular schedule to prevent bleeding episodes (prophylaxis) or on-demand when bleeding occurs. Modern factor concentrates are highly purified and safe, and some newer products last longer in the bloodstream, reducing the frequency of infusions needed.

Lifestyle

For von Willebrand disease and some other bleeding disorders, medications like desmopressin (DDAVP) can temporarily boost the body's own clotting factor levels without requiring infusions.

For von Willebrand disease and some other bleeding disorders, medications like desmopressin (DDAVP) can temporarily boost the body's own clotting factor levels without requiring infusions. This medication can be given as an injection, nasal spray, or intravenously depending on the situation. Antifibrinolytic medications like tranexamic acid help prevent clots from breaking down too quickly and are particularly useful for controlling bleeding from mucous membranes like the mouth or during dental procedures.

MedicationTopical

When bleeding disorders are acquired due to other medical conditions or medications, treatment focuses on addressing the underlying cause while managing bleeding symptoms.

When bleeding disorders are acquired due to other medical conditions or medications, treatment focuses on addressing the underlying cause while managing bleeding symptoms. This might involve adjusting blood-thinning medications, treating liver or kidney disease, correcting vitamin deficiencies, or managing autoimmune conditions. For people with low platelet counts, treatments might include medications to boost platelet production, immunosuppressive drugs if the immune system is destroying platelets, or in severe cases, platelet transfusions.

Medication

Platelet function disorders, where platelets don't work properly even though there are enough of them, often require avoiding medications that interfere with platelet function like aspirin and NSAIDs.

Platelet function disorders, where platelets don't work properly even though there are enough of them, often require avoiding medications that interfere with platelet function like aspirin and NSAIDs. For severe bleeding episodes regardless of the underlying cause, treatments might include fresh frozen plasma, cryoprecipitate, or specific blood products that provide the missing clotting components. Emergency care focuses on controlling immediate bleeding while identifying and treating the underlying problem.
