What are the causes and symptoms of stroke

A blood clot is important, because it prevents the body from losing a large amount of blood in the eve that it is cut or injured, but the occurrence of a blood clot inside the blood vessels, and its failure to dissolve it may lead to placing the patient in a dangerous and life-threatening medical condition, and accordingly the clot can be defined On the other hand, they form clumps of blood, and the state of the blood changes from a liquid state to a semi-solid state, so that it becomes like a jelly, as the formation of an immobile blood clot in the blood vessels does not cause any harm to the patient unless the clot moves from its place, except that it They may move and travel through the blood vessels to the heart or lungs, causing a blockage of blood vessels, which prevents blood flow through them, and this is what constitutes a medical emergency.

Symptoms of thrombosis:

 A clot may occur in any part of the body, and in fact the symptoms of a clot and the extent to which it threatens the life of the injured differ depending on the area in which it was formed, and the extent of its severity, and these symptoms can be explained:

Arms and legs:

 A blood clot may occur inside the deep veins in the hands or legs, and this condition is known as deep vein thrombosis as a whole that may occur inside the small blood vessels close to the skin, and with regard to the symptoms caused by the occurrence of thrombosis in the hands and legs, which is suffering from pain, swelling, and cramps, The feeling of warmth on the area when touched, in addition to the pain. Skin discoloration to red or blue.

the heart:

It contains symptoms of a blood clot occurring in the heart, which are pain in the chest and left arm, sweating, and difficulty breathing.

 The lungs:

The most common symptoms of a blood clot forming in the lungs include shortness or difficulty breathing, chest pain, and coughing. As for other symptoms, which may appear in some patients, they are: Sweating, discoloration of the skin, swollen legs, tachycardia and dizziness.

 the brain:

The formation of a clot in the brain causes the patient to suffer from problems with vision, speech, epilepsy, and general weakness. Abdomen: Symptoms of a stroke in the abdomen: severe pain in the abdomen, vomiting, nausea, diarrhea, and the appearance of blood in the stool.

Causes of thrombosis:

 There are many factors that lead to the occurrence of a blood clot, including the following: atherosclerosis:

As atherosclerosis is defined as the formation of fatty deposits known as plaque, inside the lining of the arteries, and this usually occurs due to the high level of cholesterol in the blood, and in fact a clot occurs when this plaque ruptures inside the coronary arteries, which causes permanent damage to the heart muscle or a stroke Heart attack.

 Atrial fibrillation:

Where atrial fibrillation causes an increase in the speed of the heartbeat or skips after the beats, which leads to an obstruction of blood flow, causing blood to collect inside the heart and form a blood clot, and in fact this blood clot may travel and move towards the brain causing a stroke, and it should be noted that the defibrillation Atrial is the most common type of arrhythmia.

 The American Heart Association indicated that 80% of diabetics are at risk of dying from stroke, due to the changes that diabetes causes in the blood that make the patient more susceptible to stroke.

 Inactivity for a long period of time:

As sitting or lying down for a long period of time due to traveling by plane or relaxing on the bed, leads to blood pooling in the legs, causing deep vein thrombosis, and in the event that this blood clot moves and moves to the lungs, the patient may develop a more serious condition, known as a pulmonary embolism, and to avoid Deep vein thrombosis It is recommended to move, walk, and move the legs.


Whereas, surgical procedures that require cutting or repairing arteries or veins increase the risk of blood clots. This is due to the body’s attempt to stop the bleeding that occurs through the formation of a blood clot, and in fact the risk of a blood clot forming increases during or after the operation, due to the patient’s lack of movement for a long period of time during the procedure and after its completion. That is, during the recovery phase of the operation, and it is worth noting that surgeries that require stopping the work of the heart, such as: coronary artery bypass graft increase the risk of blood clot formation.

 Cancer and its treatment:

Where cancer patients suffer from long periods of immobility, such as: the period of undergoing chemotherapy, and periods of rest after it, and in fact cancer disease and the chemotherapy used in its treatment increases the ability of blood to clot, so cancer patients should be aware of symptoms that form a blood clot.

 Genetic factors:

As there are some hereditary blood clotting disorders that increase the likelihood of a blood clot forming in their carriers compared to others, but these diseases are rare, and there is a mention of some genetic imbalances, which often cause a blood clot inside the veins, which leads to infection Deep vein thrombosis, pulmonary embolism, and blood clots in both the kidneys and intestine.
