  2. 2.Acute Variceal Hemorrhage

    Acute variceal hemorrhage is a condition that can occur secondary to (as a result of) liver disease. Blood vessels bringing blood from the digestive tract back to the heart which course through the esophagus (a muscular tube that carries food from the mouth to the stomach) become dilated. In acute variceal hemorrhage, these vessels burst, resulting in internal bleeding.

    Full recovery from hemorrhage is expected within 6 weeks.

    Uncommon
    Top Symptoms:
    being severely ill, abdominal pain (stomach ache), vomiting, constipation, lightheadedness
