Do you have a blood clot in your body? Let's learn about hematoma in simple terms!

Have you ever hit something hard and it turned blue, swollen, and painful to the touch? Or have you ever noticed that sometimes, even without an injury, the skin suddenly changes color and a blood clot appears? That's what we're going to talk about today, which is called a hematoma . There's nothing to be afraid of, let's talk about it simply.

What is this hematoma?

Simply put, a hematoma is a collection of blood inside your body that has no way to escape. Think of it like a broken water pipe collecting water in one place, but this is happening inside your body. When this blood collects, the surrounding tissue starts to push out. Small hematomas are very common and can develop anywhere on the body. Most of the time, they are not serious and will heal on their own.

However, some hematomas can be quite large, or if they form near a vital organ, they can put a lot of pressure on the surrounding tissues. That's when this becomes a situation that requires some concern. But there's nothing to worry about for small, less important hematomas.

Are there types of hematoma?

Yes, there are several types of hematomas depending on where they form. Let's see what the main types are:

• Breast hematomas
• Cephalohematomas in newborn babies
• Types of hematomas that occur inside the head, that is, inside the skull. For example , subdural hematomas and epidural hematomas are very dangerous.
• Conditions such as bleeding inside the body, specifically hemoperitoneum .
• Hematomas that occur in the muscles, such as rectus sheath hematomas, which occur near the abdominal muscles.
• Subchorionic hematomas can occur during pregnancy.
• A subungual hematoma is a bruise that forms under the nail. Sometimes, a nail on your hand or foot will become hard and blue, just like that.

What are the symptoms of a hematoma?

The larger a hematoma, the more likely it is to show symptoms. Similarly, symptoms can occur if it is confined to a small space or if it forms near important tissue.

Common symptoms

Here are some of the common symptoms:

• Pain: Since hematomas often develop after an accident, pain is the main symptom. It feels like a sharp pain in the affected area.
• Bruises/Skin discoloration: You may have noticed that a hematoma near the skin changes the color of the skin. Sometimes it can look like small red dots (called Petechiae ), or larger purple spots (called Purpura ), or even the big blue bruises we know.
• Swelling: The buildup of blood can push out surrounding tissue, such as skin or muscle, and cause it to swell. We sometimes call this edema , but when we say swelling, you get the idea.
• Nerve-related symptoms: Sometimes this hematoma can press on a nerve. This can cause numbness in the limbs (called paresthesia ), loss of sensation in certain areas, or nerve-related pain.

Dangerous symptoms - beware of these!

Some hematomas are a bit dangerous, especially those that form inside the head. Because the space for blood to collect inside our skull is very limited. When such blood collects, it can push on the brain and cause brain damage. Therefore, you need to be very careful about these symptoms.

Warning signs of intracranial hematoma

• A sudden, severe headache.
• Feeling like one side of the body or one side of the face is going numb, feeling weak.
• Nausea and vomiting.
• Difficulty speaking (Aphasia) or difficulty swallowing (Dysphagia).
• Loss of balance, inability to walk properly, and inability to coordinate muscle activity (ataxia).
• Having seizures.
• Losing consciousness, going into a coma.

Warning signs of a large hematoma in the chest or abdomen

Similarly, if a large amount of blood accumulates inside the chest or abdomen and forms a hematoma, it can also cause dangerous symptoms. These include:

• Breathing difficulties, changes in breathing patterns. For example, breathing may become faster ( tachypnea ) or slower ( bradypnea ).
• Chest or abdominal pain.
• Sudden paleness of the skin (pallor), feeling cold, and sweating.
• Severe pain, especially pain that feels much worse than a possible accident or one that cannot be explained.

What are the causes of hematoma?

The main cause of hematoma is accidents . When you hit something hard (blunt force trauma), blood starts to flow inside the body, and the blood has nowhere to go, so a hematoma forms. Think of it like if you fall somewhere, or if you hit something.

But sometimes, even if you get something stuck in your body (penetrating injuries), a hematoma can form. This is because the body quickly seals the wound to stop the bleeding (a process called hemostasis ). However, if the wound continues to bleed after it has closed, a hematoma can form.

Due to accidents

Some specific conditions that can cause an accident-related hematoma include:

• Bone fractures , especially when the bone is completely broken.
• Conditions such as a broken nose, facial fractures, or injuries to the cartilage in the ear, such as 'cauliflower ear'.
• Head injuries and traumatic brain injuries , especially intracranial bleeds .
• Injuries to internal organs , especially when there is significant bleeding.
• Things that happen during medical treatment. For example, a blown vein when an IV line is placed in the arm, or internal bleeding after surgery.
• Muscle contusions.
• Various ruptures and tears of tissue inside the body.
• Injuries caused by stretching, such as sprained joints.

Due to other medical conditions

There are also medical conditions that can cause a hematoma to form, with no risk of internal bleeding. These are:

• Tearing of a blood vessel, such as the aorta (e.g., aortic dissection).
• Clotting disorders - for example, hemophilia.
• Blood cancer - such as leukemia or lymphoma.
• Damage to blood vessels due to tumors that develop inside the body (these can be benign or malignant).
• Hemorrhagic strokes.
• Damage to internal organs due to things like kidney stones.
• Diseases that cause ulcers in the digestive system.
• Bleeding in the brain due to diseases such as high blood pressure (hypertension). (Although we say "high blood pressure", this is the medical name).
• A ruptured aneurysm is a balloon-like bulge in a blood vessel (aneurysm).
• Infectious diseases that cause bleeding inside the body, for example, some viral hemorrhagic fevers.

Can hematoma cause complications?

Most of the time, a hematoma does not cause major complications, but if there is a lot of bleeding, problems can arise. Some of the complications that can occur are:

• Hypovolemic shock: This is a shock condition caused by excessive blood loss from the body.
• Ischemia: When a hematoma compresses a blood vessel, blood flow through it is cut off, resulting in a loss of blood to that area.
• Nerve compression symptoms.

Other complications may occur depending on your health history and other factors. Your doctor can best advise you on your specific risk of complications.

How do you know exactly what a hematoma is?

A doctor can diagnose a hematoma by physically examining you and doing some imaging tests.

A physical examination is very important, especially if you have been in an accident. During this time, your doctor will look at your skin for any changes, listen with a stethoscope, and palpate. Palpation is helpful because a hematoma feels different to the touch than healthy tissue. Your doctor will also ask you about your symptoms, such as when and how they started.

Hematomas are easier to detect with imaging scans because they can look inside the body. Magnetic Resonance Imaging (MRI) scans are the best at showing hematomas, especially those that are deep inside the body. However, an MRI scan takes longer than other scans. That's why doctors also use these types of scans:

• Computed Tomography (CT) scan: This can check for hematoma inside the head that is causing pressure on brain tissue.
• Angiography: This test helps to find areas of bleeding within the body and associated hematomas.
• Ultrasound scan: This can be used to check for hematomas that are close to the skin or in specific areas, such as around the uterus.

Depending on your symptoms and health history, your doctor may recommend further tests. He or she will tell you more about how these tests can help.

How is a hematoma treated?

Small hematomas usually don't require major treatment and can be treated with simple things you can do at home. For a minor bruise or sprain, use the RICE method .

Simple things you can do at home (RICE method)

RICE is a combination of four letters. It means:

• R - Rest: Rest the injured area and it will start to heal faster.
• I - Ice: Apply an ice pack. But do not put the ice directly on the skin, wrap it in a thin piece of cloth, otherwise the skin may freeze and become injured (frostbite) .
• C - Compression: Wrap the injured area tightly, like with an elastic bandage.
• E - Elevate: Keep the injured area above your heart.

Situations requiring medical attention

If the hematoma is more serious, the first thing to do is to control any dangerous effects or complications. For example, if there is a lot of blood loss , a blood transfusion is needed, or if the heart has stopped , cardiopulmonary resuscitation (CPR) is performed to maintain blood circulation.

Once you are out of immediate danger, treatment focuses on addressing the cause of the hematoma. Some examples include:

• Surgery: Repair damaged blood vessels and tissues.
• Hematoma removal methods: For example, a procedure called centesis uses a needle to remove accumulated blood from the body.
• Fixing broken bones and placing them in a position where they cannot move.
• Removing accumulated blood: This will reduce the pressure on the surrounding areas, and it will be easier for the body to heal.
• Medications: Help control blood pressure, blood clotting problems, and other related problems.

Depending on your condition, your doctor may suggest other treatments. He or she will explain the different options to you, as well as any potential complications or side effects.

What can you expect if you have a hematoma?

If you have a hematoma, your experience will depend on a number of factors. It can be influenced by its size, the cause of the hematoma, and your medical history. Your doctor will be the best person to tell you what to expect and what to do for your specific situation. They will also tell you what your condition will look like and what you can do to improve it.

Can the formation of a hematoma be prevented?

Hematomas often form unexpectedly, making them difficult to prevent. However, there are a few things you can do to reduce your risk of developing them:

• Preventing accidents or reducing their severity: This can be done by using safety gear. For example, wearing a helmet, wearing seat belts in vehicles. Even small things can make a big difference.
• Managing chronic conditions: This can help you delay or even prevent serious conditions like stroke and brain hemorrhage. It can also reduce the risk of hematoma formation due to blood clotting/bleeding disorders.
• Be careful when exercising and training: Since hematomas can also occur due to damage to muscles and soft tissues, avoiding such damage will reduce the chances of hematomas forming.

Hematomas can also develop due to certain other long-term medical conditions. If you have one, talk to your doctor about ways to prevent hematomas.

How do I take care of myself if I have a hematoma?

The most important thing you can do to take care of yourself is to avoid worsening the injury that caused the hematoma and making it worse. Giving it time to heal is often enough. If you have any questions or concerns about how to help a hematoma heal, you should talk to a doctor. He or she can give you accurate and helpful information specific to your situation.

When should I see a doctor?

If you have these things, you should talk to or see a doctor about a hematoma.

When to usually seek medical advice

• If there is a bruise that does not heal after two weeks.
• If you have frequent bruises without finding a cause, or if you have bruises that keep coming back.
• If a bruise is accompanied by other symptoms, it could be a sign of a larger underlying problem (for example: muscle weakness, numbness, loss of sensation, skin discoloration due to poor blood circulation).

Situations where you need to go to the hospital immediately!

If you have any of these symptoms, please seek emergency medical attention immediately. These may be signs of a dangerous condition related to a hematoma:

• Difficulty breathing.
• Loss of consciousness.
• Chest pain.
• A sudden, unbearable, severe headache.
• Numbness or weakness on one side of the body.
• Difficulty maintaining balance.
• Changes in vision.
• Difficulty speaking clearly.
• Nausea and vomiting for no reason.

What questions should I ask my doctor?

Here are some questions you can ask your doctor:

• "Why did I get this hematoma?"
• "How serious is this?"
• "Can I treat this at home? Or is there anything I can do to take care of it?"
• "Does this require professional treatment? What are my treatment options?"
• "How long will it take for my hematoma to heal?"

How serious can a hematoma be?

A hematoma can range from minor to serious. The main factors that determine how serious a hematoma is are:

• What is the reason for that?
• How big is it?
• Where is it?
• Whether it could harm something around it, or is it already harming it.
• Whether this is being affected by your current or previous health condition and could make it more serious.

Think about it, a hematoma could be a small bruise from hitting your foot on a table, or it could be a purple blood clot under your nail from someone stepping on your foot. But if a hematoma is large, has spread inside your body, or is accompanied by certain symptoms, it's not a good idea to ignore it.

If you have any questions or concerns, talk to your doctor. Early diagnosis and treatment can save lives in the case of a severe hematoma. Similarly, treating minor bruises and allowing them to heal properly can help them fade as the body heals.

Finally, remember (Take-Home Message)

So, a hematoma is a collection of blood inside the body. Most of the time, these appear as small bruises and heal on their own. However, you should be very careful about large hematomas, those that occur inside the head, or those that come with dangerous symptoms such as difficulty breathing, severe headache, and loss of consciousness.

For a minor bruise, you can use the RICE method (rest, ice, compression, elevation). However, if the bruise does not improve after two weeks, if you have frequent, unexplained bruises, or if you have any of the previously mentioned dangerous symptoms, you should definitely see a doctor.

Remember, how you feel about your body is very important. If in doubt, it is never too late to seek medical advice. Stay healthy!
