Problems with veins

Problems with veins can be caused by blood flow issues. This can be due to blood clotting within the vein rather than flowing normally. It's important for blood to flow continuously in veins to prevent it clotting.

Blood clotting in the deep veins in your limbs or body is called a deep vein thrombosis (DVT). When a DVT develops, it puts pressure on the surrounding tissue and vein. Sometimes the clot can move and travel in your blood stream to your lungs, causing a pulmonary embolism (PE).

When a superficial vein clots, the vein becomes inflamed causing pain and redness. This is called a thrombophlebitis (throm-bo-fle-by-tis).

Problems with veins can also be caused by faults in the one-way valves within the veins, causing the blood to flow in the wrong direction. This is called venous insufficiency.
