decrease - peppermint,coffee,high fat
Common medications-gerd
Proton pump inhibitors
. Histamine-r2eceptoarntagonists . Antacids
. Prokinetiacgents
. Fundoplica
What is Fundoplication
, a procedure in which the fundus of the stomach is wrapped around the lower esophagus to limit reflux
Esophagitis
Inflammation, ulceration, erosions, scarring
Acute from reflux, ingestion of a corrosive agent, infection, intubation, radiation, eosinophilic infiltration
Chronic from prolonged contact with gastric acid or other irritant (e.g., NSAIDs)
Barrett’s esophagus results in 5% to 15%
Etiology of hiatal hernia
An outpouching of a portion of the stomach into the chest through the esophageal hiatus of the diaphragm
Epigastric discomfort after large, energy-dense meals
MNT hiatal hernia
Medical nutrition therapy: weight reduction, decreasing meal size
May require surgery
Difference between gastric and duodenal ulcers
Gastric ulcers: in stomach; normal or low acid secretion
Duodenal ulcers: in duodenum; high acid secretion
Gastric ulcer formation involves widespread gastritis, inflammation of oxyntic cells, and atrophy of acid- and pepsin-producing cells
Duodenal ulcers are associated with high acid and low bicarbonate secretion
Medications – ulcers n stuff
H2 receptor blockers, antacids
dumping syndrome Describe and– symptoms
Complex physiologic response to the rapid emptying of hypertonic contents into the duodenum and jejunum
Dumping syndrome occurs as a result of total or subtotal gastrectomy
Symptoms: abdominal fullness, nausea, flushing, rapid heartbeat, faintness, sweating, flatulence, abdominal cramps, diarrhea, alimentary hypoglycemia
Often causes weight loss
dumping syndrome mnt
Small meals spread throughout the day are likely to result in improved net absorption and less dramatic fluid shifts.
High-protein, moderate-fat foods are recommended, with sufficient calories for weight maintenance or gain as needed. Complex carbohydrates are included as tolerated.
Intake of fibrous foods slows upper GI transit and increases viscosity. However, to avoid obstruction, caution should be used with large particles and fiber supplements, especially with esophageal or gastric outlet narrowing or dysmotility.
Lying down and avoiding activity an hour after eating may help slow gastric emptying.
Taking large amounts of liquids with meals is thought to hasten GI transit, but adequate amounts of liquid should be consumed throughout the day, small amounts at a time.
Only very small quantities of hypertonic, concentrated sweets should be ingested. These include soft drinks, juices, pies, cakes, cookies, and frozen desserts (unless made with sugar substitutes).
Lactose, especially in milk or ice cream, may be poorly tolerated because of rapid transit and thus may need to be avoided. Cheeses and yogurt are likely to be better tolerated.
Hypoglycemia and gastrectomy
one causes the other
types of diarrhea
Osmotic
Osmotic diarrheas occur when osmotically active solutes are present in the intestinal tract and are poorly absorbed.
Secretory
Secretory diarrhea the result of active intestinal secretion of electrolytes and water by the intestinal epithelium
Medication induced be caused by several medications, but especiallyantibiotics. Antibiotics can reduce the usual “salvage” by colonic bacteria of the small amounts of foods that escape digestion and absorption.
Malabsorptive
Malabsorptive diarrheais often complicated by steatorrhea (lipid malabsorption) and maldigestion of other macronutri- ents or micronutrients.
mnt for diarrhea
Identify and treat underlying problem
Replace fluid and electrolytes; oral glucose electrolyte solutions with potassium, soups and broths, vegetable juices, and other isotonic liquids
Introduce starchy CHOs, low-fat meats, and small amounts of vegetables and fruits followed by lipids
Avoid sugar alcohols, lactose, fructose
Prebiotics and probiotics
Steateorrhea
How is it diagnosed
Diagnosis is usually basedon a ratio offecal fat to ingested fat or a coeffrcient of absorption. A diet containing 75 to 100 g of fat is usually fed for 72hours,the amount of fat actually consumed is recorded, and the fecalfat content is analyzed.The upper limit of nor- mal fecal fat is usually in the range of 7%.
MNT MCT oil – calories/rationale for using it,
The MCTs are available in some enteral formulas and also as MCT oil (8.3kcallkg).The oil is best used when it is incorporated into foods rather than administered by the spoonful.MCTs can be used to make salad dressings,sandwich spreads,or confections; and they can be substituted for fats in most recipes.Normally divided doses of less than 15 g of oil per feeding are better tolerated and absorbed than larger quantities. When steatorrhea is present, vitamin deficiencies may occur, especially of fat-soluble vitamins; calcium, zinc, and magnesium losses are increased as a result of the formation of insoluble soaps.
Constipation
High fiber/water – know recommended amounts
individuals it is a large departure from their normal intake. Reaching the recommended levels of fiber may be sufficient to achieve normal laxation in many individuals, but a high-fiber therapeutic diet may need to exceed25 to 38 g. However, amounts greater than 50 g/day are not likely to be necessary and may increase abdominal distention and excessive flatulence in some persons. Appendix 41 provides a list of the fiber content of foods
Consumption of at least eight 8-oz glasses(2 L) of fluids daily is recommended to facilitate t}le effectiveness of a high-fiber intake.
Celiac Disease
MNT
Omit sources of gluten: wheat, rye, barley
Label reading is critical
Oats are questionable
Cross-contamination must be considered
Gluten Free Grains
Use uncontaminated corn, potato, rice, soybean, tapioca, arrowroot, amaranth, quinoa, millet, and buckwheat
Lactose Intolerance and MNT
Lactose content of dairy products
Many adults with intolerance to moderate amounts of milk can ultimately adapt to and tolerate 12 g or more of lactose in milk (equivalent to 240 ml of full lactose milk)
Inflammatory Bowel Disease
Know the difference between Crohn’s disease and Ulcerative Colitis,
and common signs for both
Crohn’s disease or ulcerative colitis
Both cause diarrhea, fever, weight loss, anemia, food intolerances, malnutrition, growth failure, and extraintestinal manifestations (arthritic, dermatologic, and hepatic); associated with malignancy
Crohn’s disease: may involve any part of the GIT; most in distal ileum and colon; segments of inflamed bowel; transmural
Ulcerative colitis: is a mucosal disease of the large intestine, including the rectum
mnt for ibd
Fears and misconceptions; individualize
Nutrition support with parenteral or enteral nutrition to bring clinical remission
“Complete bowel rest” using PN not necessarily required
Enteral nutrition may temper inflammatory process and be steroid sparing and is preferred over PN
Children benefit from enteral nutrition to maintain growth and reduce steroid dependence
Vitamins, folate, vitamin B6, and vitamin B12 may require supplementation
Irritable Bowel Syndrome
MNT,
Common syndrome involving abdominal discomfort and altered intestinal motility, bloating, feelings of incomplete evacuation, mucus in stool, straining or increased urgency, GI distress with psychosocial distress
Ensure adequate nutrient intake, tailor diet for specific pattern of IBS, management of symptoms, adequate fiber, prebiotics
Pathophysiology of ibs
he normal enteric nervous system is sensitive to the presence, chemical composition, and volume of foods and also responds to a variety of inputs from the central nervous system(seeChapter1).Increasedawarenesasndsensitivity of the GI tract to internal and externalstimuli and altered modlity appearto be primary featuresof IBS
Diverticulitis/Diverticulosis
MNT for both conditions including for acute flare of diverticulitis and long term diet after inflammation is over
Herniations of the colon, chronic diverticulosis, acute diverticulitis
Diverticulosis: high-fiber diet, increase gradually, supplements if necessary, adequate fluid intake
Diverticulitis: low-residue or elemental diet, possibly low-fat diet
Seeds, nuts, or skins unresolved
