Which of the following signs indicates the presence of esophageal varices?

The presence of esophageal varices is typically associated with portal hypertension, which can lead to a range of symptoms and signs. One significant indicator of this condition is low blood pressure, particularly in the context of suboptimal blood volume and potential blood loss from ruptured varices. When esophageal varices bleed, this can cause significant blood loss into the gastrointestinal tract, leading to hypovolemia. As a result, the body may not be able to maintain adequate blood pressure, particularly in the setting of acute hemorrhage.

While high fever, constipation, and excessive thirst are not directly linked to esophageal varices, they might arise from other conditions or complications but do not serve as indicators of varices themselves. For example, a high fever may suggest infection or an inflammatory process, and constipation is generally unrelated to variceal disease. Excessive thirst typically correlates with dehydration or metabolic issues, further distancing these symptoms from the direct identification of esophageal varices.
