Beware of deep vein thrombosis (DVT)
What is it?
It occurs when a blood clot forms in one or more of the deep veins in your body, especially legs.
Why?
Long hours of sleeping in one position, or sleeping while sitting, with no movements at all.
Biggest risk
When part of the clot breaks off and travels to the lung or brain, resulting in significant damage that causes sudden death.
Signs
1. Swelling and pain in calf or ankle of the effected leg
2. Cramping in calf or thigh of that leg
3. Red, discoloured, warm skin around the affected area
4. Veins near skin's surface may become larger than usual, and may feel hard and painful to touch.
What to do?
1. Visit your doctor immediately.
2. Early diagnosis may prevent more serious complications.
3. Seek emergency medical help if there are signs of pulmonary embolism.
