Speaking of thrombus, many people, especially middle-aged and elderly friends, may change color when they hear "thrombosis". Indeed, the harm of thrombus cannot be ignored. In mild cases, it may cause ischemic symptoms in organs, in severe cases, it may cause limb necrosis, and in severe cases, it may threaten the patient's life.

What is a blood clot?

Thrombus refers to the flowing blood, a blood clot formed in the lumen of a blood vessel. In layman's terms, a thrombus is a "blood clot". Under normal conditions, the thrombus in the body will naturally decompose, but with age, sedentary and life stress and other reasons, the body's rate of decomposing thrombus will slow down. Once it cannot be broken down smoothly, it will accumulate on the blood vessel wall and is likely to move with the blood flow.

If the road is blocked, the traffic will be paralyzed; if the blood vessel is blocked, the body may "break down" instantly, leading to sudden death. Thrombosis can happen at any age and at any time. More than 90% of the thrombus has no symptoms and sensations, and even the routine examination in the hospital cannot find it, but it may occur suddenly without knowing it. Just like a ninja killer, it is silent when approaching, and deadly when it appears.

According to statistics, the death caused by thrombotic diseases has accounted for 51% of the total deaths in the world, far exceeding the deaths caused by tumors, infectious diseases, and respiratory diseases.

These 5 body signals are "early warning" reminders

Signal 1: Abnormal blood pressure
When the blood pressure suddenly and continuously rises to 200/120mmHg, it is a precursor to cerebrovascular blockage; when the blood pressure suddenly drops below 80/50mmHg, it is a precursor to the formation of cerebral thrombosis.

Signal 2: Vertigo
When thrombus occurs in the blood vessels of the brain, the blood supply to the brain will be affected by the thrombus and dizziness will occur, which often occurs after getting up in the morning. Vertigo is the most common symptom of cardiovascular and cerebrovascular diseases. If accompanied by high blood pressure and repeated vertigo more than 5 times within 1-2 days, the possibility of cerebral hemorrhage or cerebral infarction increases.

Signal 3: Fatigue in hands and feet
80% of patients with ischemic cerebral thrombosis will yawn continuously 5-10 days before the onset. In addition, if the gait is suddenly abnormal and numbness occurs, this may be one of the precursors of hemiplegia. If you suddenly feel weak in your hands and feet, unable to move one leg, unsteady gait or fall when walking, numbness in one upper and lower extremity, or even numbness in your tongue and lips, it is recommended to see a doctor in time.

Signal 4: Sudden severe headache
The main manifestations are sudden headache, convulsions, coma, drowsiness, etc., or headache aggravated by coughing, all of which are precursors of cerebrovascular blockage.

Signal 5: Chest tightness and chest pain
Sudden dyspnea after lying in bed or sitting for a long time, which is obviously aggravated after activities. About 30% to 40% of patients with acute myocardial infarction will have aura symptoms such as palpitation, chest pain, and fatigue within 3-7 days before the onset. It is recommended to see a doctor in time.
