Gastrointestinal
Tract Disorders
Disorders of the Esophagus
1. Gastroesophageal reflux disease
(GERD)
—Backward flow of the stomach and/or
duodenal contents into the esophagus
—Burning sensation after meals; heartburn
—Possible discomfort during and after eating,
change in eating habits, especially in the
evening

Disorders of the Esophagus—cont’d
2. Hiatal hernia
—An outpouching of a portion of the stomach
into the chest through the esophageal hiatus
of the diaphragm
—Heartburn after heavy meals or with
reclining after meals
—May worsen GERD symptoms

Disorders of the Esophagus—cont’d
3. Cancer of the oral cavity, pharynx, and
esophagus
—Existing nutritional problems and eating
difficulties caused by the tumor mass,
obstruction, oral infection and ulceration, or
alcoholism
—Chewing, swallowing, salivation, and taste
acuity are often affected.
—Weight loss is common.

Disorders of the Stomach
1. Indigestion/dysphagia
—Epigastric discomfort following meals
—Abdominal pain, bloating, nausea,
regurgitation, and belching
—Eat slowly, chew thoroughly, and do not
eat or drink excessively.

2. Gastritis
—Helicobacter pylori
—Infection and inflammation
—Acute gastritis: rapid onset of inflammation
and symptoms
—Chronic gastritis: occurs over period of
time
—Symptoms: nausea, vomiting, malaise,
anorexia, hemorrhage, and epigastric pain

Disorders of the Stomach—cont’d
3. Peptic ulcer disease
—Primary causes: H. pylori infection,
gastritis, use of NSAIDs, corticosteroids,
and so-called stress ulcers
—Involves gastric and duodenal regions
—Gastric ulcers: in stomach; normal or low
acid secretion
—Duodenal ulcers: in duodenum; high acid
secretion

Characteristics and Comparisons
Between Gastric and Duodenal Ulcers

Gastric ulcer formation involves inflammatory
involvement of acid-producing cells but usually
occurs with low acid secretion.

Duodenal ulcers are associated with high acid
and low bicarbonate secretion.

Increased mortality and hemorrhage are
associated with gastric ulcers.

Dumping Syndrome

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 and is associated with
mild to severe symptoms including abdominal
distention, systemic systems (bloating,
flatulence, pain, diarrhea), and reactive
hypoglycemia.

Drugs Commonly Used to Treat
Gastrointestinal Disorders

Antacids: lower acidity

Cimetidine (Tagamet), ranitidine (Zantac):
block acid secretion by blocking histamine
H2 receptors

Prostaglandins

Sucralfate: coats and protects surface

Colloidal bismuth: coats and protects surface

Carbenoxolone: strengthens mucosal barrier

Tinidazole: antibiotic

Dysphagia

Oral phase problems
Pocketing food
Drinking from cup or straw
Drooling

Pharyngeal phase
Gagging
Choking
Nasal regurgitation

Esophageal phase
Obstruction

Diagnosis of Swallowing Difficulties
1. Barium swallow
2. Cookie swallow
—Record your observations during meals
—Treatment
—Adapt consistency of food: thickened
liquids puddings, custards, pureed;
chopped or diced foods

liquid at meals

Atrophic gastritis:

Peptic Ulcer Disease
Treatment with Diet

Reduce decaffeinated and regular coffee,
cocoa, and tea intake

No alcohol or pepper

Avoid low-pH juices if they cause problems

Avoid irritating foods

Avoid food right before bedtime

Eat at least 3 small meals per day, 6 better

Disorders of the Stomach—
Nutritional Care

Lifestyle changes are an important
component of the nutrition care plan.

Patients with dyspepsia should avoid
high-fat foods, sugar, caffeine, spices,
and alcohol.

Diabetic Gastroparesis
(Gastroparesis Diabeticorum)

Delayed stomach emptying of solids

Etiology—autonomic neuropathy

Nausea, vomiting, bloating, pain

Insulin action and absorption of food not
synchronized

Prescribe small frequent meals (may need
liquid diet)

Adjust insulin
