Causes of Esophageal Varices
Esophageal varices can develop due to several causes, primarily related to liver health. One common cause is cirrhosis, which refers to the scarring of the liver tissue. When cirrhosis occurs, it interrupts the normal circulation of blood, leading to the formation of esophageal varices. Another potential cause is the occurrence of a thrombosis or blood clot in the vessels responsible for supplying blood to the liver. This clotting can also contribute to the development of esophageal varices.
In addition to liver-related causes, a parasitic infection known as schistosomiasis can also lead to the formation of esophageal varices. Schistosomiasis causes damage to various organs in the body, including the liver. This damage, in turn, disrupts the normal blood flow and can result in the development of esophageal varices.
Complications of Ruptured Esophageal Varices
When excessive pressure accumulates in the esophageal vessels, there is a risk of rupture and bleeding. The severity of the bleeding can vary, but in severe cases, it can lead to significant blood loss and potentially send the person into shock. If left untreated, this condition can be fatal. Furthermore, those who have already experienced this complication are at a higher risk of experiencing future episodes.
