Blood Clot Symptoms And Warning Signs

Blood Clot Symptoms and Warning Signs

A lot of people associate blood clots with injuries and car accidents. However, did you know that blood clots can also form in the body without any external injury? Blood clotting is a natural process that helps to stop bleeding. But sometimes, blood clots can form inside the veins, leading to serious health complications. As you read on, let’s cover in detail the symptoms and warning signs of blood clots. We will also provide tips for preventing blood clots from forming in the first place.

What are Blood Clots?

Blood clots are masses of blood that have coagulated, or thickened and solidified. They can occur anywhere in the body, but most commonly occur in the legs and arms. Blood clots are dangerous because they can break off and travel through the bloodstream to the lungs, heart, or brain, where they can cause a blockage. This can lead to a heart attack, stroke, or respiratory failure. Blood clots can also cause pain and swelling in the affected area.

How is a Blood Clot Formed?

A blood clot (thrombus) is formed when blood cells and proteins thicken and stick together. This can happen for a variety of reasons, including:

  • an injury to the blood vessel wall
  • exposure to certain chemicals
  • an abnormal increase in the clotting cells themselves

When a clot forms, it can block the flow of blood through the vessel, which can lead to serious health complications.

What is Thrombosis?

Thrombosis is the medical term used to describe the formation or development of a blood clot within a blood vessel.

Types of Blood Clot

The two main types of blood clots are classified as arterial and venous.

Arterial Blood Clot

A serious condition that can lead to potentially life-threatening complications. It occurs when a blood vessel becomes blocked by a clot, which can restrict or completely block the flow of blood. This can cause serious problems such as tissue death, organ damage, and even death.

Warning signs and symptoms of an arterial blood clot

The most common symptom of an arterial blood clot is pain. This pain is usually severe and comes on suddenly. Other symptoms may include:

  • Tingling or numbness in the affected area
  • Weakness or paralysis in the affected area
  • A change in skin colour in the affected area (pale, blue, or red)
  • A change in skin temperature in the affected area (cool to the touch)

Venous Blood Clot

Venous blood clots form in the veins. They can occur anywhere in the body, but most commonly occur in the legs. Venous blood clots can be dangerous because they can block blood flow and cause tissue damage. If a venous blood clot breaks loose, it can travel to other parts of the body and cause serious health problems.

Venous blood clots are most commonly caused by prolonged immobility, such as after surgery or during a long plane flight.

Warning Signs and Symptoms

Most people with deep vein thrombosis (DVT) experience pain, swelling, warmth and redness in the affected leg. You may also have:

  • Tenderness or cramping in the calf muscle
  • Swelling of the entire leg
  • Skin that feels warm to the touch
  • Red or discoloured skin on the leg
  • Increased skin sensitivity
  • A feeling of heaviness or tightness in the leg
  • Burning or throbbing sensation
  • Difficulty moving the leg
  • Weakness or numbness in the leg

Stroke can be a fatal consequence of untreated blood clots.

What Causes Blood Clots?

Many different factors can increase the risk of a person and contribute to the formation of blood clots. Some of the more common causes include:

  • Age – Being over the age of 60.
  • Inactivity – When you are not active, your blood flow slows down and your blood becomes more likely to clot.
  • Injury – If you have an injury, your body will work to form a blood clot to help protect the area.
  • Surgery – The healing process can sometimes cause blood clots to form.
  • Hormones – Can play a role in blood clotting. For example, estrogen can make your blood more likely to clot.
  • Birth control – Birth control pills and other contraceptives can also increase your risk of blood clots.
  • Pregnancy
  • Obesity
  • Smoking

How Do You Check for Blood Clots at Home?

There are a few ways that you can check for blood clots at home. One way is to check your pulse. You can do this by taking your own pulse or feeling for a pulse in your neck or wrist. Another way to check for blood clots is to look for signs of swelling, redness, or pain in the affected area. You should also feel for any lumps or bumps under your skin. If you notice any of these signs, it is important to contact your doctor right away.

Can Blood Clots Go Away?

Yes, blood clots can go away on their own. The body is constantly forming and dissolving blood clots, and most of them never cause any problems. However, if a person experiences symptoms that persist, medical advice and/or treatment should be sought early on.

Complications That Can Happen from a Blood Clot

Untreated blood clots can lead to serious complications, and even death, such as:

Pulmonary Embolism

A clot that forms in the veins of your leg or arm and then travels to your lungs. This can cause shortness of breath and chest pains.

Deep Vein Thrombosis

A DVT is a blood clot that develops in your arm or leg veins. This can cause pain and swelling.


A clot that forms in the arteries of your brain. This can cause paralysis and difficulty speaking.

Heart Attack

A clot that forms in the arteries of your heart. Heart attacks can cause chest pain and shortness of breath.

Main Types of Treatment in Southport QLD

Medical treatments that can be used to dissolve or break up blood clots are as follows:


Blood thinners or anticoagulants are medications that prevent new blood clots from forming and can also help to dissolve existing blood clots. Commonly used anticoagulants include heparin and warfarin.

Thrombolytic Medications

These drugs are injected into a vein and work to break up blood clots. Some examples of thrombolytic medications include alteplase and reteplase.


In some cases, surgery may be needed to remove a blood clot. This is typically only necessary if the blood clot is large or if it is causing serious complications.

Your doctor will determine the best treatment option for you based on the type and location of your blood clot, as well as your overall health.

How to Prevent Blood Clots?

There are a few things you can do to help prevent blood clots:

  • Wear loose, comfortable clothing.
  • Elevate your legs when you are sitting or lying down.
  • Get up and move around every few hours.
  • Avoid crossing your legs while sitting.
  • Don’t smoke.
  • Drink plenty of fluids.
  • Eat a healthy diet.

If you or a person you know is at increased risk for blood clots, the doctor may also prescribe medication to help prevent them.


While blood clots can happen anywhere in the body, it’s important to be aware of the risk factors and symptoms associated with them. If you experience any of these symptoms, don’t hesitate to seek medical help. There are different treatments available for blood clots, but prevention is still the best option. There are several ways you can reduce your risk of developing blood clots, including staying active, avoiding smoking and drinking alcohol, and taking medications as prescribed by your doctor.

Furthermore, being prepared in emergency cases brought about by blood clot complications can be a matter of life or death for a person. Get a first aid certification at Cnr Ferry Rd and, Cotlew St E, Southport 4215 or check out CPR First Aid’s other locations near you.
