Esophageal varices are enlarged veins found in the esophagus, the tube connecting the mouth to the stomach. Typically, they are observed in individuals suffering from liver disease. Although many people with esophageal varices may not experience any symptoms, there are potential complications that can arise, some of which may be life-threatening. As a result, individuals diagnosed with esophageal varices often require medication or surgical interventions to manage the condition.
Formation of Esophageal Varices
Esophageal varices develop as a result of liver disease, which can lead to restricted blood flow to the liver. This restriction occurs due to the formation of blood clots in the blood vessels or blockages caused by scarring in the liver. To compensate for the blockages and maintain normal blood flow, the body employs a mechanism to divert blood through smaller vessels that are ill-equipped to handle the increased blood volume. As a consequence, these vessels enlarge and can potentially rupture, giving rise to esophageal varices.
Recognizing Common Symptoms of Esophageal Varices
Esophageal varices typically do not present any noticeable symptoms unless a rupture occurs. However, once a rupture happens, there are usually clear indications that the varices in the esophagus are bleeding. One common sign is the presence of blood in vomit or black, tar-like stools. In severe cases, the individual may experience a general feeling of illness or even lose consciousness. It’s important to note that even in the absence of symptoms, a medical professional might suspect the presence of esophageal varices if the patient has a known or suspected liver disease.
