Nutrition in Patients with
Gastrointestinal Disorder
• The major organs of digestion are those
within the gastrointestinal tract (GIT),
which begins with the mouth and ends
with the anus.
• The accessory organs or digestion include
the liver, gallbladder and pancreas.
• The digestive system is responsible for
digestion (mechanical and chemical) of
food, absorption of nutrients and
elimination of waste materials.
• Digestive system
– Organs and their functions
• Mouth: beginning of digestion
• Teeth: bite, crush, and grind food
• Salivary glands: secrete saliva
• Esophagus: moves food from mouth to
stomach
• Stomach: churn and mix contents with
gastric juices
• Small intestine: most digestion occurs here
• Large intestine: forms and expels feces
• Rectum: expels feces
• Accessory organs of digestion
– Organs and their functions
• Liver: produces bile; stores it in the
gallbladder
• Pancreas: produces pancreatic juice
• Regulation of food intake
– Hypothalamus
• One center stimulates eating and
another signals to stop eating
Laboratory and Diagnostic Examinations

Upper GI series
Gastric analysis
Esophagogastroduodenoscopy (EGD)
Barium swallow
Bernstein test
Stool for occult blood
Sigmoidoscopy
Barium enema
Colonoscopy
Stool culture and sensitivity; stool for ova
and parasites
• Flat plate of the abdomen
• Digestive disorders can be due to
structural malfunction, infection,
inflammation or disease.
• The physician who specializes in treating
GI disorders is called gastroenterologist.
• The enterostomal therapist (ET) is a nurse
who assists people with learning to care
for surgically adapted openings , called
ostomies, into the stomach (gastrostomy),
intestine (ileostomy) or colon (colostomy)
DIAGNOSTIC TESTS:
PLAIN ABDOMEN: Done at random, no dietary
preparation required
BARIUM STUDIES (UPPER AND LOWER
GI SERIES)
• The patient must understand the appropriate
dietary and bowel preparations and should know
what the procedure entails.
• A substance called GOLYTELY is used. It
contains electrolytes that cause complete bowel
evacuation. The patient is instructed to eat a
light supper (some physicians require clear
liquids) in the evening and then to be on NPO,
except for the bowel prep after supper.
DIAGNOSTIC TESTS:
CHOLECYSTOGRAM
• Patient is instructed to eat a fat-free
supper the night before the X-RAY study.
Takes a radio opaque dye PO.
• Eat nothing for the next 12 hours after
taking the dye which allows time for the
dye to concentrate in the gallbladder.
• The patient may have water until bedtime
then NPO thereafter.
OTHER DIAGNOSTIC PROCEDURES:
• Gastroscopy, ERCP, colonoscopy
COMMON MEDICAL AND SURGICAL
TREATMENTS
GASTROINTESTINAL INTUBATION
• Insertion of a tube through the nostrils,
mouth or abdominal wall. (NGT,
Gastrostomy, jejunostomy.
• Used for enteral nutrition either short or
long duration
ENTERAL NUTRITION:
• Enteral nutrition also known as tube
feedings assists the patient to obtain
nutritional intake when he or she is unable
to obtain adequate calories, appropriate
nutrients, solid foods or liquids by mouth.
Patient must have a normally functioning
GI tract.

PARENTERAL NUTRITION
Parenteral nutrition involves direct IV
administration of fluids and nutrients into
the circulatory system.
This is sometimes referred to as TPN –
Total Parenteral Nutrition when the nutrient
is exclusively given via IV.
Parenteral nutrition may be given as TPN
or as supplemental.
This nutrition provides large quantities of
fluids, and nutrients which include
proteins, fats, water, electrolytes, vitamins
and minerals.
GASTRIC SURGERIES
TOTAL OR SUBTOTAL GASTRECTOMY:
• Surgical procedure to remove part of or
the entire stomach
• Postoperative complications include the
development of anemia, such as
pernicious anemia or iron deficiency
anemia.
• Electrolyte disturbance may also result
from NG suction, malabsorption, diarrhea
and vitamin deficiencies.
DUMPING SYNDROME, occurs after
gastrectomy and usually develops after
overeating or eating foods that are not
recommended.
There is rapid gastric emptying.
Symptoms include borborygmi, palpitation,
diaphoresis, faintness, excessive
weakness, and diarrhea and/or vomiting.
Foods most likely to cause dumping are
those foods high in carbohydrates and salt.
Food containing MSG, monosodium
glutamate is particularly irritating.
DUMPING SYNDROME,
Diet
- Eat 6 small meals/day
- High protein and fat, low in carbohydrates
- Eat slowly and avoid fluids during meals
- Vitamin B12 for pernicious anemia
- Recline for about an hour after meals
Gastroesophageal reflux disease (GERD)
– Etiology/pathophysiology
• Backward flow of stomach acid into the
esophagus
– Clinical manifestations/assessment

constrictive clothing, HOB up at least 6-8
inches for sleep
