Flashcards in GI disease Deck (17):
1

primary lactase nonpersistance

--genetically programmed loss of lactase activity and is permanent

2

secondary lactose intolerance

-due to transient lactase nonpersistence that can occur with factors such as surger, trauma, and some medications

3

dietary strategies to manage lactose intolerance

-complete avoidance of lactose
-consuming smal amounts of lactose at a time as part of a mixed meal
-consuming foods that contain beta galactosidase activityor adding beta galactosidase to lactose containing food

4

cause of celiacs disease

-immune mediated response to dietary gluten (a protein found in wheat, barley, and rye)
-even small amounts of gluten can result in mucosal damage and malabsorption

5

treatments of celiacs

-complete avoidance of gluten because only a small amount can be very harmful

6

dietary compliance of celiacs patients reduces the risk for

-osteoporosis
-lactose intolerance
-some cancers
-pregnancy comlications
-stunting in children

7

oral rehydrations solution

-combination of glucose, sodium, and glucose
-saves lives by relying on the sodium-glucose cotransporter in the small intestine

8

pancreatitis
-hat is it?
-characterized by

-pancreatic inflammation
-characterized by abdominal pain and increased blood levels of amylase and lipase

9

causes of acute pancreatitis

-alcohol and gall stones

10

management of acute pancreatitis

-fluid and bowel rest
-future advancement to small, frequent, low-fat meals
-severe cases may require nutrition support to prevent malnutrition

11

what might worsen the severity of pancreatitis

-not using the GI tract

12

what is chronic pancreatitis
-what does it result in

-permanent impairment of the pancreas
-results in decreased secretion of pancreatic enzymes

13

what are common symptoms of chronic pancreatitis

-fat and fat soluble vitamin malabsorption and weight loss

14

dietary management of chronic pancreatitis

-replacement of pancreatic enzymes with meals and snacks

15

-inadequate fluid and fiber intake
-physical inactivity
-medications
-divereticular disease

16

what are diverticula
-caused by

-colonic outpouchings thought to be caused by low fiber diets and resultant increase in colonic pressure

17

prevention of diverticulus
-what is this

-infection and inflammation of diverticula
-prevented by high fiber diets
