Thrombosis is a condition where a blood clot forms inside a blood vessel and can block blood flow. It can be serious, especially if the clot travels to the lungs or brain.
There are two main types:
- Deep vein thrombosis (DVT) – usually in the legs
- Arterial thrombosis – in arteries, can lead to heart attack or stroke
⚠️ Symptoms of thrombosis
Deep vein thrombosis (leg clot)
- Swelling in one leg (rarely both)
- Pain or tenderness (often in calf or thigh)
- Warmth in the affected area
- Red or darkened skin
- Leg feels heavy or tight
If clot travels to lungs (emergency)
- Sudden shortness of breath
- Chest pain (worse when breathing)
- Rapid heartbeat
- Coughing (sometimes with blood)
🚨 Why it’s dangerous
A clot can block blood flow or move to vital organs, causing:
- Pulmonary embolism (lung blockage)
- Stroke
- Heart complications
🛡️ How to help prevent it
You can reduce risk by:
- Moving regularly (avoid long sitting/bed rest)
- Walking or stretching during long travel
- Staying hydrated
- Maintaining a healthy weight
- Avoiding smoking
- Wearing compression stockings if advised
- Managing conditions like diabetes or high blood pressure
🧠 When to seek medical help
Get urgent care if you notice:
- sudden leg swelling or pain
- chest pain or breathing difficulty
- symptoms after surgery, long travel, or immobilization
Bottom line
Thrombosis is serious but often preventable. Early recognition of symptoms and maintaining good circulation habits greatly reduce risk.
