Varices
Varices are veins along the gastrointestinal tract that become swollen. These swollen parts tend to happen after trauma or when scar tissue restricts blood flow to the area. A major risk factor is alcohol-induced liver disease. This is because the heavy consumption of alcohol can make the body more susceptible to scar tissue and damage in the gastrointestinal. This damage would lead to varices, which might bleed.
Some studies have shown that around half of cirrhosis cases have varices. Bleeding and damaged varices might cause other symptoms, such as lightheadedness, weakness, confusion, fainting, bloody or black stool, vomit, and coughing. Make sure to seek medical attention as soon as you notice these signs. [6]
