1

two sources of blood to the liver

-oxygenated blood via the hepatic artery
-nutrient rich blood via the portal vein from the GI tract

2

what macronutrients are the liver involved in metabolizing

-all of them

3

steatosis

-alcoholic and nonalcoholic fatty liver

4

steatohepatitis

-fatty liver with inflammation

5

cirrhosis

-permanent destruction of normal liver tissue

6

NAFLD

-hepatic manifestation of metabolic syndrome and has been linked to obesity and diabetes

7

complications of cirrhosis

-portal hypertension which leads to development of varices (large dilated veins which commonly occur in the esophagus, stomach, or rectum) and ascites (accumulation of fluid in the peritoneal space)

8

end stage liver disease can lead to

-the development of hepatic encephalopathy or decreased mental status that can run the gamut from confusion to coma

9

patients with end stage liver disease typically end up with

-malnutrition (higher rates with liver failure due to alcoholism)
-

10

the major causes of malnutrtion due to liver disease are

-poor dietary intake
-maldigestion
-malabsorption
-abnormalities in metabolism and storage

11

the goals of nutritional support of people with end stage liver disease

-prevent or correct malnutrtion or supply adequate calories withou precipetating hepatic encephalopathy

12

nutritional support in end stage liver failure typically involves...

-sodium or fluid restriction to manage presence of ascites or edema
-small and frequent meals are prescribed to address early satiety commonly caused by ascites as well as to minimize the risk of hypoglycemia
-vitamins and minerals due to decreased intake and malabsorption

13

what is controversial in the management of hepatic encephalopathy?

-protein restriction
-may be restricted in an attempt to lower plasma ammonium levels
-however long term protein restriction is not advised since the patient will most likely be protein depleted
-BCAA supps may be considered

14

what is a common treatment for end stage liver disease

-transplant
