A blood clot forms when blood cells coagulate into a gel-like mass. This usually happens following an injury. Its function is to stop bleeding and seal the injured tissues. However, a clot may also get into the bloodstream such that it moves together with normal blood cells. This kind of blood clot poses serious danger including a heart attack and stroke.
Most blood clots form in veins, although they may also form in arteries and in different organs of the body. When a blood clot forms in a vein, deep within the muscles, it is known as deep vein thrombosis. A blood clot in a vein near the skin surface is called peripheral venous disorder, while a blood clot in the lungs is called pulmonary embolism. A blood clot in an artery leading to the heart is called coronary thrombosis. Following are 10 blood clot symptoms.
Blood Clot Symptom #1: Dizziness or Fainting
A sudden dizziness or fainting may be a symptom of a blood clot. This may occur when a clot reaches the lungs or even the head or brain. Dizziness or fainting is the result of the brain getting inadequate amounts of blood or oxygen. It is worth to note that blood clots form within the body all the time and most of them dissolve without symptoms.
However, when a large clot forms, it may not dissolve fast enough. In such a case, the clot may end up in a small blood vessel that it can’t pass through. In such a case, the clot may lodge there and interfere with the flow of blood. If this happens in the lungs, the flow of blood to the brain may be affected. This may cause the brain to get less blood and in effect, less oxygen, and lead to dizziness or fainting.
