Veins are not operating correctly. As a result, valves malfunction and blood might flow in four different ways. We refer to this blood flow backward as venous reflux. As a result, blood builds up in the legs, resulting in varicose veins. 

Widening, tortuous superficial veins in the legs subcutaneous tissues are known as varicose veins, and they are frequently very noticeable. These often have a size more than 3 mm. They are typically found inside and are five times larger. 

Women are more likely than men to have varicose veins. Patients who exhibit signs of noticeable dark blue blood vessels, particularly in the legs and feet, or who have a history of being in contact with risk factors. Assessment is necessary for diagnosis, and it is carried out via colour Doppler imaging and palpation. 

 

Risk factors in varicose veins can be classified as hormonal, lifestyle, acquired, and inherited.

Venous hypertension or thrombosis may be the cause of venous disease. Although there may be overlap with venous thrombosis because this can also result in venous hypertension, hypertension is the cause of what is known as chronic venous illness. Although pelvic venous diseases (PeVDs) and postthrombotic syndrome (PTS) are two underlying causes of chronic venous disease, the former is frequently the major cause. 

        Furthermore, there are conditions like lipedema and lymphedema that are frequently misdiagnosed.

The general population is afflicted with chronic venous disease (CVD), a disorder that significantly lowers quality of life. Some of the disease’s symptoms are less distinct, but varicose veins and venous ulcers are typically the most noticeable indicators.

 Pain is the symptom that drives CVD sufferers to seek medical attention the most often, among the other symptoms that include heaviness, edema, muscular cramps, and restless legs. Nonetheless, there is a significant disparity in the degree of pain and clinically discernible indicators.
