Which of the following are potential complications of liver failure?

In cases of liver failure, a variety of complications can arise due to the liver's crucial roles in metabolism, detoxification, and synthesis of proteins. The correct answer highlights hypoglycemia and esophageal varices as significant issues associated with liver failure.

Hypoglycemia occurs because the liver is responsible for gluconeogenesis, the process of producing glucose from non-carbohydrate sources. When liver function is compromised, the organ may struggle to maintain normal blood glucose levels, leading to hypoglycemia. This is particularly critical in patients with advanced liver disease, where metabolic regulation is impaired.

Esophageal varices are another severe complication arising from portal hypertension, which is often a consequence of liver cirrhosis or advanced liver disease. As the liver becomes scarred and its blood flow is obstructed, pressure builds up in the portal vein system, causing veins in the esophagus to distend. These veins are vulnerable to rupture, which can lead to life-threatening gastrointestinal bleeding.

The other options present complications that are less specifically associated with liver failure or have different pathological mechanisms. For example, while hypertension can be a consequence of liver issues, ascites is typically caused by portal hypertension rather than hypertension itself. Kidney failure can occur due to various reasons but is not
