We must have heard in daily life that “So-and-so had a clot in his brain” or “He was taking blood thinners because he had a clot in his blood”… So what is a clot and why are we doctors afraid of a clot?
The clot is actually the end product of a series of processes we call coagulation, which is vital for normal body functions. This product, which is called “thrombus” in the medical literature, provides the end of bleeding by blocking the hole formed in the vein in case of injury. If this coagulation does not occur in a healthy way, people can experience serious bleeding with small blows and die. So why is this substance, which is essential for life, life-threatening? If a clot forms in a place where it should not be and cuts off the blood flow there, it can disrupt the nutrition of the organ. Depending on the location, this picture can end in stroke or heart attack and death.
Deep Vein Clot (DVT) and Pulmonary Embolism
There are deep veins inside your body, away from your skin. DVT happens mainly in your leg or hip (lower extremity thrombosis), but can also develop in the arm or shoulder (upper extremity thrombosis). Small clots sometimes dissolve on their own. Large clots that don’t move or go away can block blood flow in the vein. They are dangerous if they leave because they can go to the lungs. In this way, it can block the blood flow and cannot clean the blood as it should because the lung tissue dies. It can also damage other organs. Because your lungs can’t provide them with enough oxygen. Pulmonary embolism can be fatal if the clot is very large or has more than one.
Your heart’s arteries can narrow with a buildup of fat and calcium called plaque. If the surface of the plaque is damaged, a clot forming on the plaque can cut off blood flow to the heart. If not treated quickly, some of your heart muscle may die. A heart attack often causes stabbing pain in your chest. the elderly, diabetics and sometimes women; may have other symptoms such as shortness of breath, back pain, or fatigue.
When a clot blocks blood flow in one of your brain’s arteries, that part of your brain begins to die. Symptoms of a stroke may include loss of strength in your face and arms and difficulty speaking, loss of consciousness, and unsteadiness. If you think you’ve had a stroke, you should act fast. It can cause permanent problems with speaking or using one side of your body. The sooner it is treated, the more likely your brain will recover.
Formation of Clot in the Retinal Vein
It is one of the most common causes of vision loss in older people. A clot blocking blood flow in the central vein or smaller side veins in your retina blocks the normal flow of blood. The blood leaks out of the vein and causes edema. This can lead to serious vision problems such as glaucoma or retinal detachment.
