fatty liver disease

vr.tr.fatty-liver-disease · XCT.STA

Let an agent explain fatty liver disease in general terms, relay types, new nomenclature, risk factors, assessment and management from hepatology sources, route emergencies including acute fatty liver of pregnancy, point people to clinicians and alcohol support, describe the named forms, and distinguish fatty liver disease from viral hepatitis, cirrhosis as an end stage, gallbladder disease and foie gras production, without diagnosing individuals.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain fatty liver disease in general terms, relay types, new nomenclature, risk factors, assessment and management from hepatology sources, route emergencies including acute fatty liver of pregnancy, point people to clinicians and alcohol support, describe the named forms, and distinguish fatty liver disease from viral hepatitis, cirrhosis as an end stage, gallbladder disease and foie gras production, without diagnosing individuals.

A condition in which excess fat accumulates in liver cells, including metabolic dysfunction-associated steatotic liver disease, MASLD, the name adopted in 2023 by international liver societies to replace non-alcoholic fatty liver disease, linked to obesity, type 2 diabetes and metabolic risk factors, its inflammatory form metabolic dysfunction-associated steatohepatitis, formerly non-alcoholic steatohepatitis or NASH, alcoholic fatty liver from heavy drinking, focal fatty liver seen on imaging, and acute fatty liver of pregnancy, a rare obstetric emergency in the third trimester; steatohepatitis can progress to fibrosis, cirrhosis and liver cancer. Management centres on weight loss, exercise, reducing alcohol and treating risk factors, and jaundice, confusion, vomiting blood or severe abdominal pain, including in late pregnancy, needs emergency care.

What it is for: Not applicable; a group of liver conditions.

It can be explain types and nomenclature; relay risk factors and management in general terms; describe named forms; route emergencies.

Distinguishing features

Fat accumulation

Often silent

Metabolic and alcohol causes

Risk of progression

What it looks like

Usually no visible signs early; seen on ultrasound as a bright liver.

Physical character

MASLD nomenclature adopted: 2023 year - multi-society Delphi consensus

steatosis threshold: fat in at least 5 percent of hepatocytes note

first US-approved MASH drug: resmetirom, 2024 note - check current options

How it is recognised

Excess fat in the liver

Acute fatty liver of pregnancy, alcoholic fatty liver, metabolic dysfunction-associated steatotic liver disease, steatohepatitis, focal fatty liver, non-alcoholic steatohepatitis

Viral hepatitis is infectious; cirrhosis is scarring; gallbladder disease affects bile storage; foie gras is fattened animal liver

  • How should the MASLD renaming be reflected across aliases?
  • How should treatment approvals be kept current?
