Liver Failure is a clinical syndrome where the liver cannot perform enough of its normal functions to meet the body’s needs. It is commonly discussed in emergency medicine, inpatient hepatology, intensive care, and transplant evaluation. The term is used to summarize severe liver dysfunction, not a single disease. It can develop suddenly or evolve over time from chronic liver disease.

Splenomegaly means an enlarged spleen. It is a clinical finding and a descriptive term rather than a single disease. It is commonly used in physical exam notes, imaging reports, and problem lists. In gastroenterology and hepatology, it often appears in the evaluation of portal hypertension and chronic liver disease.

Variceal Bleeding is bleeding from enlarged veins (varices) in the gastrointestinal (GI) tract. It most often involves the esophagus or stomach in people with portal hypertension. Portal hypertension usually results from advanced liver disease such as cirrhosis. The term is commonly used in emergency care, endoscopy units, intensive care, and hepatology.

Hepatic Encephalopathy is a brain function disorder caused by severe liver dysfunction or blood bypassing the liver. It can range from subtle attention changes to confusion, sleepiness, and coma. It is most commonly discussed in cirrhosis and in patients with portosystemic shunts. In clinical practice, it is used as a diagnostic framework for altered mental status related to liver disease.

Ascites is the abnormal buildup of fluid inside the peritoneal cavity (the space within the abdomen). It is most commonly discussed in liver disease, especially cirrhosis, but it has many possible causes. Clinicians use the term Ascites in physical exams, imaging reports, and procedure notes. It can range from mild, incidental fluid to tense fluid that affects breathing and mobility.

Portal Hypertension means abnormally increased pressure in the portal venous system. It most often occurs in people with advanced chronic liver disease, but it can also have non-cirrhotic causes. It is commonly discussed in hepatology, gastroenterology, endoscopy, and GI surgery because it drives major complications like varices and ascites.

Nonalcoholic steatohepatitis (NASH) is a liver disease defined by fatty change (steatosis) plus liver cell injury and inflammation. It sits on the spectrum of fatty liver disease that is not primarily caused by heavy alcohol use. NASH is commonly used as a clinical and pathology term in hepatology, gastroenterology, primary care, and metabolic medicine. It matters because it can be associated with liver scarring (fibrosis) and, in some people, progression to cirrhosis.

NAFLD stands for nonalcoholic fatty liver disease. It describes excess fat in the liver that is not primarily explained by significant alcohol use. NAFLD is commonly used in hepatology and gastroenterology to classify metabolic-associated liver injury. It appears in clinic notes, imaging reports, and lab-based risk assessments for chronic liver disease.

Fatty Liver refers to excess fat accumulation within liver cells (hepatocytes). In clinical language, this is called hepatic steatosis. It is commonly discussed in primary care and gastroenterology when liver enzymes are abnormal or imaging shows “fatty infiltration.” It can occur without symptoms and may be discovered incidentally.

Liver Fibrosis is the buildup of scar-like tissue in the liver after repeated or long-lasting injury. It reflects a wound-healing response that becomes excessive and disorganized over time. Clinicians use the term to describe disease stage and risk of complications. It is commonly discussed in chronic liver diseases such as viral hepatitis, alcohol-associated liver disease, and metabolic dysfunction-associated steatotic liver disease.
