Blood clots are a serious health problem that many people don’t fully understand. Learning the warning signs, risk factors, and ways to prevent them can be truly lifesaving.
What Is a Blood Clot?
When you first get a cut, your body forms a blood clot to stop the bleeding. This is a normal and helpful process. However, blood clots can sometimes form inside blood vessels when they are not needed. These clots can be dangerous.
The two main types of blood clots are:
Deep Vein Thrombosis (DVT)
A deep vein thrombosis happens when a blood clot forms in a deep vein, usually in the leg or arm. Less often, it can happen in other parts of the body, such as the abdomen or brain.
Pulmonary Embolism (PE)
A pulmonary embolism is a medical emergency. It happens when a blood clot breaks loose and travels through the bloodstream to the lungs. The clot can block blood flow and make it hard for the body to get enough oxygen. This condition can be life-threatening and requires immediate medical attention.
Spotting the Warning Signs
Recognizing the symptoms of a blood clot can help you get the treatment you need quickly.
Symptoms of DVT
A blood clot in the leg or arm may cause:
- Swelling in the affected arm or leg
- Pain or tenderness, especially when standing or walking
- Skin that feels warm to the touch
- Red or discolored skin
- Veins that appear larger or more noticeable than usual
Symptoms of PE
A pulmonary embolism may cause:
- Sudden shortness of breath
- A fast or irregular heartbeat
- Chest pain, especially when taking a deep breath or coughing
- Coughing, sometimes with blood
- Feeling dizzy, lightheaded, or faint
- Anxiety or a feeling that something is wrong
If you have any symptoms of a pulmonary embolism, get medical help right away.
Who Is at Risk?
Anyone can develop a blood clot, but some things can increase the risk.
Risk factors include:
- Sitting or lying down for long periods of time, such as travel by air or in the car for 2 or more hours
- Recent surgery, especially joint replacement surgery
- Recovering after a surgical procedure (especially if immobile)
- Certain health conditions, including cancer, heart disease, lung disease, or broken bones
- Taking birth control pills or hormone replacement therapy
- Pregnancy and during the first six weeks after giving birth
- Getting older, especially after age 40
- A family history of blood clots or inherited clotting disorders
- Being overweight or having obesity
How Can You Help Prevent Blood Clots?
There are several steps you can take to lower your risk:
- Keep moving. If you sit for long periods, stand up and walk around every hour or two. If you cannot get up, move and stretch your legs and feet.
- Drink plenty of water. Staying hydrated helps keep blood flowing normally.
- Maintain a healthy weight. Excess weight can increase your risk.
- Exercise regularly. Physical activity improves circulation and helps prevent blood clots.
- Talk with your healthcare provider. If you are at higher risk, your provider may recommend compression stockings or medications such as blood thinners.
Don't Ignore the Warning Signs
If you think you may have a blood clot, it’s important to get help. Always contact your healthcare provider if you have symptoms of a deep vein thrombosis. If you have symptoms of a pulmonary embolism, you must seek emergency medical care immediately since it is life-threatening.
The good news is that finding and treating blood clots early can prevent serious complications. Knowing the warning signs and understanding your risks can help protect your health.
