What Is Hemorrhage?

A hemorrhage (also spelled “haemorrhage”) refers to bleeding—either inside the body or out—when a blood vessel is damaged and blood escapes into surrounding tissues or outside the body. Depending on the location, volume and speed of blood loss, hemorrhages range from minor to life-threatening events.

Understanding hemorrhages can help you recognize warning signs and act quickly when they occur. Below, we explain what a hemorrhage is, common causes, the main types, and which situations are medical emergencies.

Definition and Causes

A hemorrhage happens when:

• A blood vessel (artery, vein or capillary) is injured.
• Blood leaks out faster than the body can clot it.
• The lost blood either pools inside the body or flows out as visible bleeding.

Common causes include:

• Trauma: cuts, falls, car accidents or sports injuries.
• Medical conditions: high blood pressure, aneurysms or clotting disorders.
• Surgical procedures: postoperative bleeding.
• Medications: blood thinners (anticoagulants) or anti-platelet drugs.
• Underlying diseases: liver disease, hemophilia or cancer.

Knowing the cause helps guide treatment and prevention.

Classification of Hemorrhage

Hemorrhages are often categorized by:

1. Location

   • External: visible bleeding from a wound
   • Internal: blood loss inside the body (not immediately visible)

2. Speed and Volume

   • Acute: rapid loss of a large volume of blood
   • Chronic: slow, ongoing blood loss over days or weeks

3. Source

   • Arterial: bright red, spurting with each heartbeat
   • Venous: darker red, steady flow
   • Capillary: slow oozing

4. Clinical Impact

   • Minor: small cuts or bruises
   • Major: causes low blood pressure, shock or organ damage

Types of Hemorrhages

Below are common types of hemorrhages, grouped by general area:

1. Head and Brain

• Subarachnoid Hemorrhage
  Bleeding into the space between the brain and the tissues covering it. Often caused by a ruptured aneurysm.
• Epidural Hematoma
  Blood collects between the skull and the outermost brain membrane. Frequently from head trauma.
• Subdural Hematoma
  Blood gathers between the brain’s surface and the middle layer of membranes. May be acute or chronic.
• Intracerebral Hemorrhage
  Bleeding directly into the brain tissue, often linked to high blood pressure or stroke.

2. Gastrointestinal (GI)

• Upper GI Hemorrhage
  Bleeding from the esophagus, stomach or first part of the small intestine (e.g., ulcers, varices).
• Lower GI Hemorrhage
  Bleeding from the large intestine, rectum or anus (e.g., diverticulosis, inflammatory bowel disease).

3. Obstetric/Gynecologic

• Postpartum Hemorrhage
  Excessive bleeding after childbirth, a leading cause of maternal morbidity worldwide.
• Ectopic Pregnancy Rupture
  Bleeding when a fertilized egg implants outside the uterus (often in a fallopian tube).

4. Trauma and Soft Tissue

• Major Trauma
  Gunshot wounds, stab wounds or crush injuries can cause massive external or internal bleeding.
• Muscle/Tendon Injuries
  Deep bruises or torn muscles can lead to large hematomas.

5. Other

• Nosebleeds (Epistaxis)
  Common and often minor, but can become serious if heavy or recurrent.
• Dental Bleeding
  Post-extraction bleeding can sometimes require medical attention.

Emergency Hemorrhages

Certain types of bleeding demand immediate medical attention. Recognizing these can save lives.

• Intracranial Hemorrhage
• Sudden severe headache (“worst headache of life”)
• Loss of consciousness, confusion, weakness on one side
• Massive GI Bleeding
• Vomiting bright red blood or coffee-ground material
• Black, tarry stools or bright red rectal bleeding
• Postpartum Hemorrhage
• Heavy vaginal bleeding after delivery
• Signs of shock: rapid pulse, low blood pressure, dizziness
• Ectopic Pregnancy Rupture
• Sharp abdominal pain, vaginal bleeding, shoulder pain (referred)
• Major Trauma with External Bleeding
• Spurting bright red blood (arterial bleed)
• Soaking through bandages/towels quickly
• Signs of Shock
• Pale, clammy skin; rapid heartbeat; confusion; fainting

If you observe any of these signs, call emergency services (e.g., 911) immediately.

Warning Signs and Symptoms

Hemorrhage symptoms vary by location but may include:

• Visible bleeding (external wounds, nosebleeds)
• Unusual bruising or swelling
• Severe headache or neck stiffness
• Abdominal pain or distension
• Vomiting blood or passing black stools
• Rapid heart rate, low blood pressure
• Weakness, dizziness or fainting
• Confusion or altered mental status

Early warning signs may be subtle—if you’re unsure, it’s better to get evaluated.

What to Do If You Suspect a Hemorrhage

1. Stay Calm
   Panic can worsen symptoms.
2. Apply Direct Pressure (external bleeding)
   Use a clean cloth or bandage to press firmly on the wound.
3. Lay the Person Down
   Elevate legs slightly unless there’s head, neck or back injury.
4. Monitor Vital Signs
   Watch pulse, breathing and level of consciousness.
5. Call for Help
   Dial emergency services if bleeding is heavy, rapid or internal.

Prevention and When to Seek Medical Advice

• Manage chronic conditions (e.g., high blood pressure, liver disease).
• Use blood-thinning medications only as prescribed; report unusual bleeding.
• Wear protective gear during high-risk activities.
• Keep first-aid supplies on hand.

Always speak to a doctor about any bleeding that:

• Lasts longer than 10 minutes despite pressure
• Occurs after minor trauma without an obvious cause
• Is accompanied by weakness, dizziness or confusion
• Follows surgery, childbirth or a medical procedure

Conclusion

Hemorrhages range from minor nuisances (small cuts, bruises) to life-threatening emergencies (intracranial bleeding, massive GI loss, postpartum hemorrhage). Recognizing the type and severity of bleeding can help you respond quickly and effectively.

If you ever face serious or unexplained bleeding, don’t wait—seek immediate medical attention. And remember, for non-emergency guidance you can always try a free, online symptom check, using the doctor approved Ubie Symptom Checker.
