The Dangers of blood clots

Understanding Blood Clots: When They're Good, and When They're Not

Imagine this: you have an open wound.

Within minutes, your blood cells clump together, forming a clot. This natural process seals the wound and prevents further blood loss. It’s an essential part of the body’s healing process—a good thing.

Now, picture a clot forming deep within a vein in your leg.

In this case, the leg starts to swell, and you may experience pain. Worse, the clot can break free, travel to your lungs, and block blood flow—a life-threatening situation. This is not a good thing.

What Causes Blood Clots?

When blood flow in a vein is disrupted, it can lead to the formation of a blood clot, known as deep vein thrombosis (DVT). Various factors contribute to DVT, ranging from inflammation and infection to trauma or surgery. Certain conditions can increase your risk, such as:

Sitting for extended periods (e.g., during long flights or road trips)

Recent surgery

Vein injuries

Extended bed rest

Being overweight

Age (60+)

Use of oral contraceptives or hormone replacement therapy

Pregnancy

Heart failure

Smoking

Cancer

Inflammatory bowel disease (IBD)

Family history of DVT

Inherited genetic factors

Recognizing the Symptoms of Deep Vein Thrombosis

DVT can develop without noticeable symptoms, but common signs often include pain in the calf, swelling, discolored skin, and a sensation of warmth in the affected area.

Recent Concerns: Blood Clots in the News

Blood clots have become a topic of heightened concern recently, especially in connection with COVID-19 vaccines. The European Medicines Agency (EMA) has acknowledged a potential link between rare blood clots and low platelet counts in individuals who received the Janssen COVID-19 vaccine. This is similar to concerns raised with the AstraZeneca vaccine.

This complex issue requires more research and time to fully understand, but ongoing data collection will help clarify these possible side effects.
