Thrombosis formation is a complex biological process that centers on the abnormal aggregation and clotting of blood components. When our blood vessels suffer damage, platelets quickly accumulate at the site of injury, forming a primary thrombus to prevent blood from spilling out. Subsequently, the coagulation process is initiated, and the clotting factors are activated and converted into specific enzymes, which in turn convert the hemolysogen in the plasma into fibrin. These fibrin proteins form a network structure with the help of platelets, which makes the blood clot stronger.
In addition, red blood cells and other blood cells are captured by this fibrous web, eventually forming a stable blood clot. However, there are also potential dangers to this process. If a blood clot breaks away from where it formed and travels with the bloodstream to other parts of the body, it can lead to serious health problems such as pulmonary embolism or cerebral embolism, which can be life-threatening by blocking important blood vessels and affecting blood flow.
Causes of blood clots
Changes in blood characteristics: High cholesterol and blood sugar levels directly affect the viscosity of the blood, making it easier for lipid plaques and blood clots to form. Especially in diabetic patients, hyperglycemia not only damages the lining of blood vessels, but also increases the number of platelets, further increasing the risk of blood clots.
Cardiovascular health: People with cardiovascular disease are more likely to develop blood clots. Arteriosclerosis causes narrowing of blood vessels, obstruction of blood flow, and susceptibility to thrombosis. Hypertension is also a key factor, affecting hemodynamics and increasing the deposition of blood components, thereby promoting thrombosis.
Genetic background: Some people are more predisposed to blood clots due to genetic reasons, such as hereditary coagulation disorders such as factor V Leiden mutations or prothrombin mutations.
Lifestyle and external environment: Prolonged sitting or inactivity can reduce blood circulation and promote platelet aggregation to form blood clots. In addition, surgery, trauma or use of certain medications, as well as extreme temperatures, can increase the risk of blood clots.
To prevent blood clots, we should maintain appropriate exercise, avoid sitting for long periods of time, limit alcohol consumption, and maintain a comfortable living environment. Early recognition of the signs of blood clots is essential to reduce the risk of the resulting medical emergency.
Let's take a look at the small symptoms that are the precursors of blood clots
Unilateral salivation during sleep: It is normal for most people to occasionally drool while sleeping. However, especially in older age groups, if you find yourself drooling all the time on the same side, this can be a warning sign. This may be due to impaired muscle coordination due to blockage of blood vessels in the brain, resulting in involuntary salivation to one side during sleep. When this happens, it is advisable to seek medical attention in a timely manner.
Frequent dizziness: While occasional dizziness may be caused by everyday factors such as low blood sugar or rapid movement, recurrent dizziness may be an early warning of cerebral thrombosis. Especially in the morning, after taking a shower, or after a long working day, if severe dizziness occurs, it can be caused by obstructed blood circulation. In this case, it is recommended to go to the hospital for a professional examination as soon as possible.
Numbness in the limbs: Occasional numbness in the limbs occurs when you sit for too long or stay in the same position for a long time. However, if you still feel numbness in your hands and feet, especially in your legs, after a change in posture, this may also be a sign of a circulation problem. Blood clots can cause poor blood flow, which can cause numbness in the limbs.
Unilateral salivation, frequent dizziness, and numbness in the limbs during sleep can all be early signs of cerebral thrombosis. If these symptoms appear, it is advisable to consult a medical professional in a timely manner and undergo the necessary examinations.
