GASTROINTESTINAL
SYSTEM
Gastroenterology is the branch of medicine that focuses on
the diagnosis and treatment of diseases of the
gastrointestinal (GI) tract, including the esophagus,
stomach, intestines, liver, gallbladder, and pancreas.
Organs Involved:
•Esophagus
•Stomach
•Small intestine
•Large intestine (colon)
•Rectum and anus
•Liver
•Gallbladder
•Pancreas
Functions of the Gastric
Function Description
Ingestion Taking in food through the mouth
Digestion Breaking down food into smaller molecules (mechanical +
chemical)
Absorption Nutrients from digested food are absorbed into the blood (mostly
in the small intestine)
Secretion Digestive enzymes, acids (like HCl), bile, and mucus are secreted
to aid digestion
Motility (Peristalsis) Coordinated muscular contractions move food through the GI
tract
Excretion (Defecation) Removal of undigested food and waste products via the rectum
as feces
Immune Function The GI tract contains gut-associated lymphoid tissue (GALT) to
protect against pathogens
Specific Organ Functions:
Organ Function
Mouth Chewing (mechanical digestion), salivary enzyme action (amylase)
Esophagus Moves food to stomach via peristalsis
Stomach Stores food, secretes acid (HCl), digests protein (pepsin), churns food
Liver Produces bile to digest fat, detoxifies substances
Gallbladder Stores and releases bile
Pancreas Secretes digestive enzymes and bicarbonate into small intestine
Small Intestine Major site of digestion and absorption of nutrients
Large Intestine (Colon) Absorbs water and electrolytes, forms stool
Rectum and Anus Stores and expels feces
Digestive Enzymes
• Mouth – Begins Digestion
Action: Chewing (mechanical digestion)
Enzyme: Salivary amylase
Acts On: Carbohydrates (starch)
Function: Breaks starch → maltose
• Step 2: Esophagus – Food Transport
Action: Peristalsis moves food to stomach
No enzymes
No digestion
Stomach – Protein Digestion Begins
Action: Churns food into chyme (mechanical)
Enzymes:
Pepsin (activated by HCl) → starts protein digestion
Gastric lipase → begins fat digestion (minor)
Acts On: Proteins and fats
Small Intestine – Main Site of Digestion & Absorption
➤ In Duodenum:
• Pancreas enzymes enter:
• Pancreatic amylase → carbs
• Trypsin, chymotrypsin → proteins
• Pancreatic lipase → fats
• Liver/Gallbladder:
• Release bile → emulsifies fats (helps lipase work)
➤ In Jejunum/Ileum:
• Intestinal enzymes:
• Maltase → maltose → glucose
• Sucrase → sucrose → glucose + fructose
• Lactase → lactose → glucose + galactose
• Peptidase → peptides → amino acids
• Large Intestine – Absorbs Water
No enzymes
Absorbs water, electrolytes
Forms stool
• Rectum/Anus – Elimination
Stores and expels feces
No digestion
Risk Factors for GI Disorders
Risk Factor Impact on GI System
Food/Drug Allergies Can trigger GI inflammation, nausea, vomiting, or diarrhea
Cardiac, Respiratory, Endocrine Disorders May slow GI motility → constipation or delayed emptying
Chronic Alcohol Use Damages mucosa → gastritis, pancreatitis, liver disease
Chronic Stress Affects GI motility → ulcers, IBS, indigestion
Chronic Laxative Use Leads to dependency and decreased natural bowel function
Chronic NSAID/Aspirin Use Causes mucosal erosion → ulcers, gastritis, bleeding
Diabetes Mellitus Increases risk of oral candidiasis, gastroparesis, constipation
Family History of GI Disorders Increases risk of IBD, colorectal cancer, GERD
Long-Term GI Disorders (e.g., UC) Raises risk of colorectal cancer
Neurological Disorders Affects chewing, swallowing, or peristalsis
Previous Abdominal Surgery/Trauma Can cause adhesions → bowel obstruction or altered motility
Tobacco Use Increases acid, delays healing, promotes GI malignancies
DISORDERS
Gastro esophageal Reflux Disease (GERD)
Gastro esophageal reflux is the backward flow of gastric content into
the esophagus
Signs and symptoms
Heartburn after meals, while bending over, or recumbent
May have regurgitation of sour materials in mouth, pain with
swallowing
Dyspepsia or indigestion
Atypical chest pain
Sore throat with hoarseness
17
Diagnosis
a. Barium swallow (evaluation of esophagus, stomach, small
intestine)
b. Upper endoscopy: direct visualization; biopsies may be
done
a.24-hour ambulatory pH monitoring
Medical management
Antacids for mild to moderate symptoms, e.g. Maalox, Mylanta,
Gaviscon
b. H2-receptor blockers: decrease acid production. e.g.
cimetidine, ranitidine, famotidine, nizatidine
c. Proton-pump inhibitors: reduce gastric secretions, promote
healing of esophageal erosion and relieve symptoms, e.g.
omeprazole (prilosec); lansoprazole
b.Promotility agent: enhances esophageal clearance and gastric
emptying
e.g metachlopromide
18
Nursing management
a. Elimination of acid foods (tomatoes, spicy, citrus foods, coffee)
b. Avoiding food which relax esophageal sphincter or delay gastric
emptying (fatty foods, chocolate, alcohol)
c. Maintain ideal body weight
d. Eat small meals and stay upright 2 hours post eating; no eating 3
hours prior to going to bed
e. Elevate head of bed on 6 – 8 blocks to decrease reflux

f. No smoking
a.Avoiding bending and wear loose fitting clothing
b.Drink adequate fluids at meals to increase food passage
c.Decrease the intake of highly seasoned foods
19
Gastritis
• Inflammation of the stomach lining (gastric mucosa) caused by
irritants or infection.
Category Examples
Medications NSAIDs, corticosteroids (↑ acid, ↓
mucus)
Infection H. pylori (most common chronic
cause)
Lifestyle Alcohol, caffeine, smoking, stress
Autoimmune Chronic gastritis (↑ risk of cancer)
CAUSES
Signs & Symptoms:
Epigastric pain or burning (esp. after eating)
Nausea/Vomiting
Bloating
Loss of appetite
Hematemesis (vomiting blood – red or coffee-ground)

Nursing Interventions:
Action Why/
NPO during acute symptoms Rest GI tract
Monitor for GI bleeding Look for hematemesis, melena, ↓ Hgb
Avoid irritants No alcohol, caffeine, spicy foods, smoking
Administer meds as ordered PPIs (omeprazole), H2 blockers (ranitidine), antacids
If H. pylori positive Start triple therapy: PPI + 2 antibiotics
Medications
Class Examples NCLEX Note

    Gastroenterology is thebranch of medicine that focuses on the diagnosis and treatment of diseases of the gastrointestinal (GI) tract, including the esophagus, stomach, intestines, liver, gallbladder, and pancreas.
  • 5.
    Organs Involved: •Esophagus •Stomach •Small intestine •Largeintestine (colon) •Rectum and anus •Liver •Gallbladder •Pancreas
  • 6.
  • 7.
    Function Description Ingestion Takingin food through the mouth Digestion Breaking down food into smaller molecules (mechanical + chemical) Absorption Nutrients from digested food are absorbed into the blood (mostly in the small intestine) Secretion Digestive enzymes, acids (like HCl), bile, and mucus are secreted to aid digestion Motility (Peristalsis) Coordinated muscular contractions move food through the GI tract Excretion (Defecation) Removal of undigested food and waste products via the rectum as feces Immune Function The GI tract contains gut-associated lymphoid tissue (GALT) to protect against pathogens
  • 8.
  • 9.
    Organ Function Mouth Chewing(mechanical digestion), salivary enzyme action (amylase) Esophagus Moves food to stomach via peristalsis Stomach Stores food, secretes acid (HCl), digests protein (pepsin), churns food Liver Produces bile to digest fat, detoxifies substances Gallbladder Stores and releases bile Pancreas Secretes digestive enzymes and bicarbonate into small intestine Small Intestine Major site of digestion and absorption of nutrients Large Intestine (Colon) Absorbs water and electrolytes, forms stool Rectum and Anus Stores and expels feces
  • 10.
    Digestive Enzymes • Mouth– Begins Digestion Action: Chewing (mechanical digestion) Enzyme: Salivary amylase Acts On: Carbohydrates (starch) Function: Breaks starch → maltose • Step 2: Esophagus – Food Transport Action: Peristalsis moves food to stomach No enzymes No digestion
  • 11.
    Stomach – ProteinDigestion Begins Action: Churns food into chyme (mechanical) Enzymes: Pepsin (activated by HCl) → starts protein digestion Gastric lipase → begins fat digestion (minor) Acts On: Proteins and fats
  • 12.
    Small Intestine –Main Site of Digestion & Absorption ➤ In Duodenum: • Pancreas enzymes enter: • Pancreatic amylase → carbs • Trypsin, chymotrypsin → proteins • Pancreatic lipase → fats • Liver/Gallbladder: • Release bile → emulsifies fats (helps lipase work) ➤ In Jejunum/Ileum: • Intestinal enzymes: • Maltase → maltose → glucose • Sucrase → sucrose → glucose + fructose • Lactase → lactose → glucose + galactose • Peptidase → peptides → amino acids
  • 13.
    • Large Intestine– Absorbs Water No enzymes Absorbs water, electrolytes Forms stool • Rectum/Anus – Elimination Stores and expels feces No digestion
