Gastrointestinal (GI) disorders are common secondary conditions of developmental disabilities. The four most prevalent disorders, which are described in detail in this document, are gastroesophageal reflux disease, gastritis, chronic constipation, and chronic diarrhea.
Many treatments are available to relieve symptoms of gastrointestinal disorders. It is important to note, however, that many of these treatments fail to cure the underlying problem. Because the patient may not experience pain or discomfort, it is possible for internal damage to continue without the physician’s knowledge, which can lead to serious conditions if not addressed.
The recommendations presented in this document are in addition to the normal medical care provided to an individual without gastrointestinal disorders. All recommendations can be addressed through clinical examination by the primary care provider, unless otherwise noted.
Gastroesophageal reflux disease (GERD) is a chronic, progressive disorder involving the backward flow of gastroduodenal contents into the esophagus. GERD is the most common serious condition of the gastrointestinal (GI) tract. It is caused by (1) a defective lower esophageal sphincter; (2) a gastric emptying disorder; or (3) failed esophageal peristalsis.
GERD affects 15-20% of the developmentally disabled population.

Gastritis is an inflammatory reaction in the stomach, typically involving the mucosa. Symptoms include epigastric distress (often aggravated by eating), anorexia, nausea with or without vomiting, and hiccups.
DGR is diagnosed by isotopic gastric emptying studies. H. pylori infection may be diagnosed by endoscopic biopsy with CLO test and histopathological exam.
Almost all treatment is outpatient, except for severe hemorrhagic gastritis caused by stress ulceration. Most cases clear spontaneously when the cause has been identified and treated, although H. pylori infection may require a repeated course of treatment.
Duodeno-gastric reflux (DGR) :
Chronic constipation is a condition in which the stool accumulates, hardens, blocks up, and/or is difficult to expel, which may lead to three or more days between bowel movements. Chronic constipation is a symptom of an underlying problem and an issue for many people with developmental disabilities.

Chronic diarrhea is characterized by the frequent passage of unformed, watery stools for more than three to four weeks.
Inflammatory diarrhea: inflammatory bowel disease, radiation enterocolitis, eosinophilic gastroenteritis, HIV/AIDS
Osmotic diarrhea: pancreatic insufficiency, bacterial overgrowth, celiac disease, lactase deficiency, Whipple’s disease, abetalipoproteinemia, short bowel syndrome, medications (colchicine, neomycin, para-aminosalicylic acid)
Factitious: laxative abuse
Secretory diarrhea: carcinoid syndrome, Zollinger-Ellison syndrome, vasoactive intestinal peptide-secreting pancreatic adenomas, medullary carcinoma of thyroid, villous adenoma of rectum, microscopic colitis, choleraic diarrhea
Altered intestinal motility: irritable bowel syndrome, fecal impaction, neurologic diseases, diabetes
Idiopathic diarrhea: unknown cause
Phase I: Lifestyle and Diet Modifications
Phase II: Medication (if lifestyle and diet modifications not effective)
