The liver is an internal organ; it lies on the right side of the abdomen, behind the lower ribs, and below the diaphragm.

Liver failure means that your liver doesn’t function well as before. It suggests severe damage (loss of 80-90% of liver cell function). Liver failure happens suddenly in weeks or even days without pre-existing liver disease. It often occurs after an overdose of drugs or poisoning.
You are at risk for acute liver failure if you:
- Take so much acetaminophen

- Jaundice: a yellowish color of skin and eyes
- Fetor hepaticus: musty breath odor due to failure of hepatic detoxification of mercaptans
- Ascites: accumulation of fluids in the abdomen
- Hepatic encephalopathy: mental deterioration due to brain affection by ammonia
Possible complications of acute liver failure are:
- Brain swelling
- Mental Disturbances

- If acetaminophen toxicity, your doctor will give you an antidote to treat the drug toxicity.
- If viral hepatitis, your doctor will treat you according to the type of hepatitis. For example, steroids have a role in the treatment of autoimmune hepatitis.

- Excess alcohol intake can damage your liver.
- Viral infections as hepatitis and herpes simplex virus
- Impaired liver blood supply, which occurs in patients with cardiac, respiratory, or renal failure
- Neoplastic infiltration, acute Budd-Chiari syndrome, heatstroke, mushroom ingestion, and metabolic diseases as Wilson’s disease
- Acute fatty liver in pregnancy
- Unknown causes
