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.

Disorders of the Stomach—cont’d 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 © 2004, 2002 Elsevier Inc. All rights reserved.

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 © 2004, 2002 Elsevier Inc. All rights reserved.

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 © 2004, 2002 Elsevier Inc. All rights reserved.
