Haemorrhage

Symptoms You might develop signs and symptoms of an intracranial hematoma right after a head injury, or they may take weeks or longer to appear. You might seem fine after a head injury. This period is called the lucid interval. Over time, pressure on your brain increases, producing some or all of the following signs and symptoms: • Headache that gets worse • Vomiting • Drowsiness and progressive loss of consciousness • Dizziness • Confusion • Unequal pupil size • Slurred speech • Loss of movement (paralysis) on the opposite side of the body from the head injury As more blood fills your brain or the narrow space between your brain and skull, other signs and symptoms may appear, such as: • Lethargy • Seizures • Unconsciousness When to see a doctor An intracranial hematoma can be life-threatening, requiring emergency treatment. Seek immediate medical attention after a blow to the head if you: • Lose consciousness • Have a persistent headache • Experience vomiting, weakness, blurred vision, unsteadiness If you don't notice signs and symptoms right after you've been hit in the head, watch for physical, mental and emotional changes. For example, if someone seems fine after a head injury and can talk but later becomes unconscious, seek immediate medical care. And even if you feel fine, ask someone to watch out for you. Memory loss after a blow to your head can make you forget about the blow. Someone you tell might be more likely to recognize the warning signs and get you medical ...

Internal bleeding, or hemorrhaging, is bleeding that occurs when blood vessels become damaged inside the body. Depending on the severity and location, it can lead to weakness and dizziness, low blood pressure, organ failure, and death. Internal bleeding in the brain can result in a stroke. Very minor hemorrhages, such as small, ruptured blood vessels near the surface of the skin, are common and usually only produce tiny red specks on the skin or minor bruising. But large, uncontrolled hemorrhages are life-threatening and are one of the leading causes of death worldwide. Hemorrhaging is not a condition in itself, meaning it always has an underlying cause. The most common reason for a hemorrhage is a traumatic injury. Share on Pinterest Internal bleeding may cause a bruise to appear at the affected site. One of the reasons internal bleeding is so dangerous is because the bleeding itself is not visible. It is hard to ignore a bleeding cut or wound on the outside of the body. But it can be easy to overlook bleeding deep inside the body until it begins to cause life-threatening symptoms. As blood is crucial to the functioning of nearly every organ and type of body tissue, blood loss causes a wide range of symptoms that can seem unrelated. Symptoms of moderate to severe internal bleeding include: • light-headedness or dizziness • a • • general weakness • unexplained exhaustion • muscle and joint pain, aching, and weakness • lower • confusion, memory loss, or disorientation • num...

A hemorrhage usually results from either a severe blow to the body or from medication being taken for something else. Though many hemorrhages aren't particularly serious, those that occur in the brain (cerebral hemorrhages) can be life-threatening. In older people, hemorrhages are often caused by blood-thinning medication taken to prevent heart attacks. A bruise (or hematoma) is a hemorrhage close enough to the surface of the skin to be visible. Hemorrhage is also a verb, which isn't always used to talk about actual blood; thus, we may hear that a business is hemorrhaging money, or that the U.S. has been hemorrhaging industrial jobs for decades. Be careful when writing hemorrhage; it's not an easy word to spell.

Hemorrhages range from slight bleeding from a shaving nick, a bruise due to bleeding beneath the skin (bruises appear bluish because the skin affects the way the blood looks), to hemorrhages caused by events like trauma, stroke, or aneurysm (a bulge in an artery). Commonly, the term applies to sudden and severe blood loss. • Arterial hemorrhage: This is usually severe and a medical emergency. Blood can spurt out in a pulsing rhythm as the heart beats to pump out blood. Arteries deliver oxygenated blood from the heart to the body. The oxygen attached to iron-containing hemoglobin in red blood cells gives arterial blood a bright red color. • Venous hemorrhage: This can also be severe and life-threatening. Bleeding is steady rather than pumping. Veins carry blood back toward the heart. The blood is a darker red because it has less oxygen attached to its hemoglobin. • Capillary hemorrhage: This is often less serious. Capillaries are small, thin blood vessels that deliver nutrients through the body, like tributaries from a river. Blood trickles out of capillaries until the body's clotting agents close over the wound or cut. • Class 1: Up to 15% blood loss, heart rate may increase slightly • Class 2: 15–30% blood loss, causing rapid heartbeat and breathing • Class 3: 30–40% blood loss, causing an increased heart rate, decreased blood pressure, changes in mental state, difficulty returning blood to the capillaries, and decreased urine output • Class 4: More than 40% blood loss, w...

Broken blood vessel in the eye A broken blood vessel in the eye may look alarming, but it's usually harmless. A subconjunctival hemorrhage (sub-kun-JUNK-tih-vul HEM-uh-ruj) occurs when a tiny blood vessel breaks just underneath the clear surface of your eye (conjunctiva). In many ways, it's just like having a bruise on your skin. The conjunctiva can't absorb blood very quickly, so the blood gets trapped. You may not even realize you have a subconjunctival hemorrhage until you look in the mirror and notice that the white part of your eye is bright red. A subconjunctival hemorrhage often occurs without any obvious harm to your eye. Even a strong sneeze or cough can cause a blood vessel to break in the eye. You don't need to treat it. A subconjunctival hemorrhage may look alarming, but it's usually a harmless condition that disappears within two weeks or so. Symptoms The most obvious sign of a subconjunctival hemorrhage is a bright red patch on the white (sclera) of your eye. Despite its bloody appearance, a subconjunctival hemorrhage looks worse than it is and should cause no change in your vision, discharge or pain. Your only discomfort may be a scratchy feeling on the surface of the eye. When to see a doctor If you have recurrent subconjunctival hemorrhages or other bleeding, talk to your doctor. Causes The cause of a subconjunctival hemorrhage isn't always known. The following actions may cause a small blood vessel to rupture in your eye: • Violent coughing • Powerful sne...

Hemorrhage is bleeding from a damaged blood vessel. Many things can cause hemorrhage inside and outside the body. Types of hemorrhage range from minor, such as a bruise, to major, such as bleeding in the brain. If you can’t stop external bleeding or suspect internal bleeding, seek immediate medical attention. Possible Causes What are the most common causes of hemorrhage? There are many possible causes of hemorrhage, including: • Alcohol, drug or tobacco use that is heavy or long-term (bleeding in the brain). • • • Complications from medical procedures, such as surgery or childbirth. • Damage to an internal organ. • Hereditary (inherited) disorders, such as • Injuries, such as cuts or puncture wounds, • Violence, such as a gunshot or knife wound, or physical abuse. • Viruses that attack the blood vessels, such as Depending on the location or cause, a hemorrhage might be called: • • Hemothorax, blood collecting between the chest wall and lungs. • • • Petechiae, tiny spots on the skin that may be purple, red or brown. • Postpartum hemorrhage, more bleeding than normal after childbirth. • • • How might bleeding make me feel?
