# Cirrhosis
---
**Cirrhosis** is a condition of irreversible, scarring damage to the [[liver]]. The liver is a vital organ that performs many functions, so damage to it impedes its function and ultimately leads to death.
- *repeated* damage to the cells of the liver
- causes inflammation and cell death
- the cells are replaced with scar tissue, or fibrosis
- the liver is unable to function

With such scarring in the liver, it has lost a large capacity to move blood through it, which backs up the flow of blood in the [[hepatic portal system|hepatic portal vein]]. This then causes congestion in the organs that drain into the portal vein, which can in turn affect their functions:
- [[stomach]]
- [[pancreas]]
- we might see trouble with [[insulin]] production
- [[spleen]]
- we might see splenomegaly
- [[intestines]]
- water and nutrient absorption troubles
## Risk Factors
- [[alcohol use disorder]]
- see: [[hepatitis#Non-Viral Hepatitis|alcohol-related hepatitis]]
- viral [[hepatitis]]
- injection drug use
- [[hepatotoxic substances]] or recreational drugs
- fatty liver
## Signs & Symptoms
There are a wide range of signs and symptoms of cirrhosis, since this touches so many systems and has such a widespread effect.
- The liver is able to clear ammonia
- [[hepatic encephalopathy]], altered mental status, asterixis
- The liver is unable to clear bilirubin
- [[jaundice]], icterus (yellow sclera)
- The liver is unable to make [[albumin]]
- blood osmotic pressure goes down, fluid escapes into the tissues, [[ascites]]
- The liver does not trigger platelet production
- bleeding, prolonged INR
- bruising, petechia
- Blood backs up in the portal system
- [[esophageal varices]], caput medusae
## Diagnostic Tests
- liver enzymes (AST, ALT) *elevated*
- bilirubin elevated
- albumin lowered
- PT/INR prolonged
- ammonia elevated
- RBC/HGB/HCT/PLT lowered
## Treatment
Cirrhosis is incurable, so treatment consists of symptom management. The only possible "cure" for cirrhosis is a [[organ transplant|liver transplant]].
