Recognizing Blood Clot Warning Signs: A Guide to Staying Safe

Blood clots are a serious health concern that can happen to anyone but knowing what to look for can make a huge difference in outcomes. While clotting is a normal bodily function to stop bleeding after an injury, clots that form inside your veins without a good reason can be dangerous. At INTEGRIS Health, we want you to feel empowered to spot the early warning signs of blood clots so you can act fast.

We speak to Michael Megaly, M.D., MS, an interventional cardiologist at the INTEGRIS Health Heart Hospital, to learn more. 

Understanding blood clots

The basics: Blood clots can be life-threatening if not treated promptly. Recognizing the signs early and knowing when to seek care can save lives. Here’s what you need to know.

• Blood clots can form in veins (deep vein thrombosis) or travel to the lungs (pulmonary embolism).
• Symptoms often include swelling, redness and pain in the affected area.
• Risk factors include prolonged immobility, commonly a long drive or a long flight, surgery and certain medical conditions.
• Understanding the risks and symptoms is the first step in prevention.

Early warning signs of a blood clot

The signs: Spotting the early signs of a blood clot can prevent serious complications. Pay attention to these symptoms and act quickly.

• Swelling in one leg or arm, often accompanied by pain or tenderness.
• Red or discolored skin, especially in the affected area.
• Sudden shortness of breath or chest pain could indicate a pulmonary embolism, which happens when a clot travels from the leg veins into the lung arteries causing blockages.

Swelling in one leg or arm is one of the most common indicators that something is wrong with your circulation.

• This swelling often appears suddenly and doesn’t go away with rest or elevation.
• You might notice that one leg looks significantly larger than the other.
• Pain or tenderness usually accompanies the swelling, often starting in the calf and feeling like a cramp or “charley horse.”

Red or discolored skin can appear over the area where the clot has formed, often feeling warm to the touch.

• The skin might look reddish or even bluish, depending on the severity of the blockage.
• The affected area will likely feel warmer than the surrounding skin.
• You might also see veins that look larger or more prominent than usual near the skin’s surface.

Sudden shortness of breath or chest pain could indicate pulmonary embolism, which means the clot has traveled to the lungs.

• This can happen without any warning signs in the legs first.
• You might feel a sharp pain in your chest that gets worse when you take a deep breath or cough.
• Other signs can include a rapid heart rate or coughing up blood.

When to seek emergency care

When to get help: Some blood clot symptoms require immediate medical intervention. Delaying care can lead to life-threatening complications.

• Sudden, severe chest pain or difficulty breathing.
• Fainting, dizziness or rapid heartbeat.
• Swelling and pain that worsens quickly.

Tips to help prevent blood clots

Tips: While some risk factors for blood clots are unavoidable, there are steps you can take to reduce your risk.

• Stay active and avoid sitting for long periods.
• Wear compression stockings if recommended by your doctor.
• Stay hydrated and maintain a healthy weight.
• Incorporating small changes into your daily routine can make a big difference.

Stay active and avoid sitting for long periods because movement helps pump blood back to your heart, preventing it from pooling and clotting.

• If you’re on a long flight or road trip, take breaks to walk around every hour or two.
• Even flexing your ankles or tightening your calf muscles while sitting can help keep blood flowing.
• Regular exercise improves overall circulation and lowers your risk.

Wear compression stockings if recommended by your doctor to help improve blood flow in your legs.

• These special socks gently squeeze your legs to prevent blood from settling.
• They are especially helpful after surgery or during long travel.
• Talk to your doctor about the right fit and pressure level for you.

Stay hydrated and maintain a healthy weight to keep your blood from becoming too thick and sluggish.

• Drinking plenty of water helps prevent dehydration, which can thicken your blood.
• Excess weight puts extra pressure on the veins in your pelvis and legs.
• Avoiding smoking is also critical, as smoking affects blood circulation and clotting.

Small changes can have a huge impact on your vascular health over time.

• If you work a desk job, try a standing desk or set a timer to stand up and stretch.
• Make movement a non-negotiable part of your day.
• Listen to your body. If something feels off, get it checked.

Understanding your risk factors

Key points: Certain conditions and lifestyle factors can increase your risk of developing blood clots. Knowing your risk can help you take preventive measures.

• Prolonged immobility, such as during long flights or hospital stays.
• Recent surgery or injury, especially involving the legs.
• Medical conditions like cancer, pregnancy or clotting disorders.
