Varices are enlarged, twisted, and often painful veins that can occur in various parts of the body. While "varices" is a broad medical term encompassing a range of vein abnormalities, it is commonly associated with varicose veins, a specific type of vein disorder. In this blog, we will explore what varices are, their causes, symptoms, and treatment options, and clarify the relationship between varices and varicose veins.
Varices refer to abnormally dilated and tortuous veins that can develop in different areas of the body. They are most commonly seen in the legs, where they are known as varicose veins, but can also occur in the esophagus (esophageal varices), stomach (gastric varices), rectum (rectal varices), and other parts of the body. Varices are often the result of increased pressure within the affected veins, which can lead to their enlargement and distortion.
Varicose veins are a type of varices caused by vein disease that specifically affect the veins in the legs. They appear as bulging, twisted, and discolored veins that are often visible just beneath the skin. While varicose veins are a form of varices, not all varices are varicose veins. Varices is a broader term that encompasses various types of abnormal vein conditions, including but not limited to varicose veins.
While the causes of esophageal and other varices and varicose veins differ significantly, both conditions are linked to increased pressure within the venous system—whether due to portal hypertension in the case of esophageal varices or valve failure in the veins of the legs for varicose veins. The management and treatment of these conditions also vary, with esophageal varices often requiring more urgent and complex medical interventions due to the risk of life-threatening bleeding, while varicose veins can frequently be managed with minimally invasive outpatient procedures.
The causes of varices, such as esophageal varices and varicose veins, are multifaceted and largely depend on the underlying conditions that lead to increased pressure in the venous system or damage to the veins themselves. Here, we delve into the primary causes of these conditions, highlighting the differences and similarities in their origins.
According to the Mayo Clinic, esophageal varices are enlarged veins in the esophagus. This tube connects the throat and stomach and is often a consequence of severe liver disease such as cirrhosis of the liver. Cirrhosis, in turn, can result from a variety of liver diseases, including hepatitis infection, alcoholic liver disease, fatty liver disease, and a bile duct disorder known as primary biliary cholangitis. The progression of these liver diseases leads to the formation of scar tissue (cirrhosis), which obstructs blood flow through the liver. This obstruction causes blood to back up, increasing pressure within the portal vein system—a condition known as portal hypertension.
As a result, blood seeks alternative pathways through smaller veins, such as those in the esophagus, leading to the formation of esophageal varices. These veins are not designed to carry such high volumes of blood and can become dilated and burst, posing a risk of severe bleeding.
Varicose veins, on the other hand, are primarily caused by weakened or damaged valves in the veins, usually in the legs, resulting from chronic venous insufficiency. These valves are meant to keep blood flowing toward the heart, but when they fail, blood can flow backward and pool in the veins. This pooling causes the veins to become enlarged, twisted, and sometimes painful.
Several factors can contribute to the development of varicose veins, including:
Age: Aging causes wear and tear on the valves in the veins, increasing the risk of varicose veins.
Genetics: Several studies have shown that vein disease runs in families. Per the National Library of Medicine (NIH), children have a 90 percent risk if both parents have the condition and a 25-62 percent risk with one affected parent. Individuals run a 20 percent risk if neither parent has problem veins.
Being female: Women are more likely to develop varicose veins, possibly due to hormonal changes that relax vein walls during menstruation, pregnancy, and menopause. Hormone treatments, such as birth control pills, might also increase the risk.
Pregnancy: The increase in blood volume during pregnancy supports the growing fetus but can also enlarge the veins in the legs.
Obesity: Being overweight puts additional pressure on the veins, increasing the chances of developing problem veins.
Prolonged standing or sitting: This can impede blood flow, contributing to the development of varicose veins.
Understanding the causes of varices, whether esophageal or varicose, is crucial for effective prevention, diagnosis, and treatment. While the underlying mechanisms differ, the impact on individuals' health can be significant, underscoring the importance of medical attention and care for those affected by these conditions.
The symptoms of varices can vary depending on their location. In the case of varicose veins, individuals may experience pain, aching, heaviness, swelling, and visible bulging veins in the legs. Esophageal varices, on the other hand, may present with symptoms such as vomiting blood, black or tarry stools, and abdominal pain. It is essential to seek medical attention if any concerning symptoms related to varices are experienced.
Here are the common symptoms associated with each type:
