Excessive blood clotting can result from numerous risk factors. Blood clots could migrate to the blood vessels in the heart, brain, lungs, kidneys and limbs, leaving you at risk of a stroke or heart attack. Moreover, a blood clot may lead to limited or even blocked blood flow, causing damage to your body’s organs. While some risk factors are acquired, others are genetic. Additionally, some health issues like diabetes and deep vein thrombosis may result in excessive blood clotting.
