Chapter 3 – Digestive Disorders, Awareness of Celiac Disease is Growing
Learning Objectives:
• Describe the gastrointestinal disorders addressed in lecture: their causes, their effects on
nutritional health, and any nutritional or other interventions that are commonly used as
treatments.
• Discuss (briefly) potential use of probiotics in digestive disorders
Heartburn and gastroesophageal reflux disease (GERD)—is painful, persistent heartburn
Causes
HCl in esophagus
Hiatal hernia – diaphragm helps separated esophagus and stomach
--stomach is outside the diaphragm
Causes = Smoking, alcohol use, overweight, pregnancy, large high fat meals, lying down within
1-2 hours after a meal, certain foods
How to treat?
Eat small meals, don’t lay down right away after eating, elevate head of bed, stop smoking, lose
weight, antacids
Antacids – neutralize HCl, inhibit pepsin production
Ulcers (peptic ulcers)—not everyone
Erosion of an area of the stomach or part of duodenum due to exposure to (eroded by) HCl
and pepsin
Burning pain~1-3 hours after a meal
Can lead to loss of blood and subsequent anemia
Causes –
H. pylori—bacterium Helicobacter pylori
Chronic non-steroidal anti-inflammatory medications

Antibiotics
Antacids—decrease the acidic of the environment
Food allergies and intolerances
Causes –
Allergy –An allergic reaction to a food caused by a reaction of the immune system
--results when the immune system mistakenly targets a harmless food protein—an allergen—as a
threat and attacks it
--food allergies are IgE (immune cell) mediated
--body produces abnormally large amounts of an antibody called
Common allergenic foods – eggs, seafood, wheat, milk, soy, nuts, sesame seeds
“exotic foods”
-increased reported allergy reactions
-kiwi, mango, papaya, seeds (sesame, poppy, mustard)
Symptoms
• mouth - swelling of the lips
• digestive tract - stomach cramps, vomiting, diarrhea
• skin - hives, rashes or eczema
• airways - wheezing or breathing problems
• Anaphylaxis - difficulty breathing, swelling of the mouth and throat, a drop in blood
pressure, and loss of consciousness
Treatment –
avoid offending foods
if exposed to food
• Antihistamines
• Epinephrine (Epipen)
• Reverse symptoms of anaphylaxis
Intolerance – gastrointestinal discomfort (gas, pain, diarrhea, or constipation) caused by foods
(example - lactose intolerance)
Common intolerances - wheat, milk, and soy
Lactose intolerance – inadequate lactase production
• Lactose reaches the large intestine
• Lactose causes bloating, gas, diarrhea
Approximately 75% of the world’s population is affected by lactose intolerance.
