What do you know about venous disease? Reminder: These 5 common venous lesions should not be underestimated!

As we all know, there are a large number of blood vessels distributed in various organs and tissues of the human body. The value of their existence is to transport blood containing oxygen and nutrients, and then reabsorb and utilize the blood.

　　Because of this, the division of labor between blood vessels is clear, and it can be divided into three major parts, namely arterial blood vessels, venous blood vessels and capillaries.

　　Normally, there are more venous blood vessels in the human body than arterial blood vessels, but in the past, the focus of everyone's attention was on the arteries. Because many fatal diseases are related to arterial damage, such as stroke, coronary heart disease, myocardial infarction and other cardiovascular and cerebrovascular diseases, all are based on arterial disease . Therefore, everyone pays special attention to the arteries, while ignoring the venous blood vessels.

　　As everyone knows, venous blood vessels may also be damaged and sick. The following types of diseases are common venous lesions:

　　1. Varicose veins

　　The so-called varicose veins refer to the fact that the vein wall is too weak and the blood pools , which leads to the tortuous and dilated veins of the patient . Usually, varicose veins may appear in the veins in many parts of the body, such as the well-known hemorrhoids, which are actually a type of varicose veins.

　　In addition, gastric varicose veins, lower extremity varicose veins, abdominal varicose veins, etc. are all venous diseases. But relatively speaking, varicose veins of the lower extremities are the most common type. However, it should be emphasized here that varicose veins are often secondary manifestations of other diseases;

2, venous dysfunction

　　This condition often occurs on the venous blood vessels of the lower extremities of the patient, which may have U shield Acura symptoms, such as fatigue and weakness of the legs, pain, edema, etc. , especially when the patient sits for a long time or stands for a long time. . Leg swelling caused by long-term cycling, sedentary, etc. is actually a precursor to venous dysfunction;

3. Venous congestion

　　This situation refers to the obstruction of the venous return of organs and local tissues, resulting in blood pooling in small veins and capillaries , and then congestion occurs. This is also a venous secondary disease, which is mostly related to venous compression, venous cavity obstruction, heart failure, pulmonary heart disease and other diseases;

4. Thrombophlebitis

　　It includes two major parts of superficial thrombosis and deep thrombosis, which is a disease based on thrombosis. After thrombosis, the vein will produce an inflammatory response to the thrombosis.

　　The most typical clinical symptoms of the disease are redness, swelling, pain along the veins , and obvious tenderness. When palpating the affected area, a distinct cord-like vein can be palpated;

5. Deep vein thrombosis of lower extremities

　　This is one of the common diseases that appear on the veins, which refers to the coagulation of venous blood in the veins of the lower extremities, which can cause many problems such as lower extremity edema, varicose veins, pigmentation, and stasis ulcers .

　　The causes of lower extremity venous thrombosis are related to multiple factors such as prolonged bed rest, prolonged sedentary, varicose veins, venous wall damage, and blood in a hypercoagulable state .

　　All in all, there are many types of diseases that appear on the veins, and the causes of the disease are very complex and the symptoms of the disease are different.

　　If edema, varicose veins, or pain has suddenly appeared in a certain place recently, you should be vigilant and seek medical attention in time for relevant examinations, so as to avoid the occurrence of lesions without knowing it and miss the best time for diagnosis and treatment.
