1. Don't double up on doses. Ask your doctor what you should do if you accidentally miss a dose of your blood thinner.
2. Be more careful when you exercise or are doing activities. "Even a trivial cut is going to bleed a lot on these medications," says Molly Cooke, MD, of the University of California, San Francisco.
3. Wear gloves when you use sharp objects like scissors, knives, and gardening tools.
4. Switch to an electric razor.
5. Wear shoes as often as possible -- always when you mow the...
The life cycle of a normal blood clot depends on a series of chemical interactions.
1. Platelets form a plug. Tiny bits in your blood called platelets get "turned on" by triggers released when a blood vessel is damaged. They stick to the walls in the area and each other, changing shape to form a plug that fills in the broken part to stop blood from leaking out.
When activated, platelets also release chemicals to attract more platelets and other cells, and to set off the next step.
2. The clot grows. Proteins in your blood called clotting factors signal each other to cause a rapid chain reaction. It ends with a dissolved substance in your blood turning into long strands of fibrin. These get tangled up with the platelets in the plug to create a net that traps even more platelets and cells. The clot becomes much tougher and more durable.
3. Reactions stop its growth. Other proteins offset extra clotting factor proteins so the clot doesn't spread farther than it needs to.
4. Your body slowly breaks it down. As the damaged tissue heals, you don't need the clot any more. The tough fibrin strands dissolve, and your blood takes back the platelets and cells of the clot.
What Causes Blood Clots?
The process begins whenever flowing blood comes into contact with specific substances in your skin or in blood vessel walls. When they touch, it usually means the skin or blood vessel wall is broken.
Waxy cholesterol plaques that form in arteries have these things inside, too. If the plaque breaks open, they'll start the clotting process. Most heart attacks and strokes happen when a plaque in your heart or brain suddenly bursts.
Blood clots can also form when your blood doesn't flow properly. If it pools in your blood vessels or heart, the platelets are more likely to stick together. Atrial fibrillation and deep vein thrombosis (DVT) are two conditions where slowly moving blood can cause clotting problems.
