Medical Nutrition Therapy - A. GI Disorders (p. 1-5) Flashcards
An eroded mucosal lesion. The cause of many ____ is the H. pylori bacteria.** Diet: As tolerated (whatever does not aggravate the patients condition). May wish to omit gastric irritants (black pepper, caffeine, alcohol)
Ulcer
Gastric surgery connecting the remaining stomach to the duodenum.
Billroth 1
Gastric surgery connecting the remaining stomach to the jejunum. Jejunum further along SI than duodenum, making this a more serious procedure.
Billroth 2
Protrusion of a portion of the stomach above the diaphragm into the chest. Main symptom is heart burn.
Hiatal hernia
Hiatal hernia diet therapy: _____, _____ feedings. Avoid late night snacks and gastric irritants.
Hiatal hernie diet therapy: *SMALL, BLAND feedings.
Dumping syndrome follows a ____________. Types include Billroth 1 and Billroth 2.
**Dumping syndrome follows a GASTRECTOMY.
In dumping syndrome, the holding capacity of the stomach is _______, so the food is literally dumped into the ______.
Decreased, intestine
When rapidly hydrolyzed (simple) CHO enter the jejunum, _________ is drawn from the blood into the SI to achieve osmotic balance. This causes a rapid _______ in the vascular fluid compartment, or rapid drop in _______ ______, and signs of cardiac insufficiency.
When rapidly hydrolyzed (simple) CHO enter the jejunum, WATER is drawn from the blood into the SI to achieve osmotic balance. This causes a rapid DROP in the vascular fluid compartment, or rapid drop in BLOOD PRESSURE, and signs of cardiac insufficiency.
~__ hours later, this CHO is rapidly digested and absorbed, causing a sharp ______ in blood sugar, _______ of insulin, followed by a sharp _____, or REACTIVE HYPOGLYCEMIA.
~2 hours later, this CHO is rapidly digested and absorbed, causing a sharp RISE in blood sugar, OVERPRODUCTION of insulin, followed by a sharp DROP in blood sugar, or REACTIVE HYPOGLYCEMIA.
Following Billroth 2, where the ________ is being bypassed, secretion of SECRETIN and CCK is ______, also _______ pancreatic secretion. This adversely effects absorption of _______, whose absorption is most rapid in the _____, and ______, whose absorption requires acidity. Iron, B12 (lack of intrinsic factor), and Folate (lack of B12 and iron) may arise.
Following Billroth 2, where the DUODENUM is being bypassed, secretion of SECRETIN and CCK is DECREASED, also DECREASING pancreatic secretion. This adversely effects absorption of CALCIUM, whose absorption is most rapid in the DUODENUM, and IRON, whose absorption requires acidity. Iron, B12 (lack of intrinsic factor), and Folate (lack of B12 and iron) may arise.
*______ Diet: -Small, frequent meals -Limit fluids during meals (drink before and after) -Restrict simple sugars (CHO) -Protein at each meal -Moderate fat (lactose may be poorly tolerated due to rapid transport)
DUMPING DIET* -Small, frequent meals -Limit fluids during meals (drink before and after) -Restrict simple sugars (CHO) -Protein at each meal -Moderate fat (lactose may be poorly tolerated due to rapid transport)
Delayed gastric emptying. Due to surgery, diabetes, obstructions.
Gastroparesis
_________ can ________ gastric emptying. This may lead to long-term, detrimental effects on GASTRIC NERVES and motility.
Hyperglycemia can slow gastric emptying.
__________, medications that control acid reflux, INCREASE stomach contractility, also INCREASING gastric emptying time.
Prokinetics
A _____ is a disease of the small intestine.
Sprue
There are 2 types of sprue: ________ and ______.
Tropical sprue and Non-tropical sprue
A chronic GI disease characterized by intestinal lesions related to bacterial, viral or parasitic infection. Symptoms include deficiencies in vitamin B12 and folate (due to decreased HCl and IF). Associated with diarrhea and malnutrition.
Tropical Sprue
Gluten-induced enteropathy (CELIAC DISEASE)
Non-tropical sprue
Diet therapy in Gastroparesis: Small, frequent meals, _______ foods (liquid better tolerated), AVOID high fiber.
Gastroparesis: Small, frequent meals Pureed foods Avoid High Fiber
Diet therapy for Tropical Sprue: Antibiotics High Cal High ______ Supplementation of deficient nutrients: _____ and ____
Tropical Sprue: Hi Cal Hi Pro B12, Folate supps
______ refers to STORAGE PROTEINS. (Prolamins: protein found in grains. Ex. gliadin in wheat)
Gluten refers to STORAGE PROTEINS.
In ____ disease, there is damage to the VILLI –> MALABSORPTION (leads to loss of fat soluble vitamins, diarrhea, steatorrhea, iron-deficiency, ANEMIA)
Celiac disease
Diet therapy for ______: Gliadin-free, Gluten-restricted diet (NO wheat, rye, oats, barley)
Celiac disease
Diet therapy for _____ includes high fluid, high fiber diet and exercise.
Constipation
The presence of small mucosal sacs that protrude through the wall of the intestine due to structural weakness.
Diverticulosis (sacs=diverticula)
Diet therapy for Diverticulosis: *_____ fiber diet
Diet therapy for Diverticulosis: *HIGH fiber diet (provides rapid transit)
Once diverticula become inflamed as a result of food and residue accumulation and bacteria.
Diverticulitis
Diet therapy for Diverticulitis: *Begin with clear liquids. Advance as tolerated to ______ fiber, low-residue and advance back to ____ fiber gradually.
Diet therapy for Diverticulitis: *Begin with clear liquids. Advance as tolerated to LOW fiber, low-residue and advance back to HIGH fiber gradually.
_____ provides indigestible bulk and promotes intestinal function. Nondigestible CHO and lignin.
Fiber
Oat bran and SOLUBLE FIBERS decrease serum ______ by binding bile acids and converting cholesterol–>bile, lowering the serum level.
Cholesterol
Pectins and gums are examples of ____ fibers.
Soluble
