Gastrointestinal tract: disorders of motility

To Prepare

· Review Chapter 35 in the Huether and McCance text. Identify the normal pathophysiology of gastric acid stimulation and production.

· Review Chapter 37 in the Huether and McCance text. Consider the pathophysiology of gastroesophageal reflux disease (GERD), peptic ulcer disease (PUD), and gastritis. Think about how these disorders are similar and different.

· Select a patient factor different from the one you selected in this week’s Discussion: genetics, gender, ethnicity, age, or behavior. Consider how the factor you selected might impact the pathophysiology of GERD, PUD, and gastritis. Reflect on how you would diagnose and prescribe treatment of these disorders for a patient based on this factor.

· Review the “Mind Maps—Dementia, Endocarditis, and Gastro-oesophageal Reflux Disease (GERD)” media in the Week 2 Learning Resources. Use the examples in the media as a guide to construct a mind map for gastritis.

To Complete

Write a 2- to 3-page paper that addresses the following:

• –  Describe the normal pathophysiology of gastric acid stimulation and production. Explain the changes that occur to gastric acid stimulation and production with GERD, PUD, and gastritis disorders.
• – Explain how the factor you selected might impact the pathophysiology of GERD, PUD, and gastritis. Describe how you would diagnose and prescribe treatment of these disorders for a patient based on the factor you selected.
• – Construct a mind map for gastritis. Include the epidemiology, pathophysiology, and clinical presentation, as well as the diagnosis and treatment you explained in your paper.

· This paper should have at least 4 current references (Year 2013 and up)

· At least 2 references should be from the class Learning Resources below

This chapter presents information relating to disorders of the gastrointestinal tract and accessory organs of digestion. It also covers the pathogenesis, clinical manifestations, evaluation, and treatment of gastroesophageal reflux disease, gastritis, peptic ulcer disease, inflammatory bowel disease, and irritable bowel syndrome.

• Chapter 37, “Alterations of      Digestive Function in Children”

This chapter presents information relating to disorders of the gastrointestinal tract and liver that affect children. It focuses on congenital impairment, inflammatory disorders, metabolic disorders, as well as the impairment of digestion, absorption, and nutrition.

This chapter provides a foundation for exploring gastrointestinal disorders by reviewing the structure and function of the GI tract. It also describes mechanisms of regulation of GI tract disorders such as acid-peptic disease, inflammatory bowel disease, and irritable bowel syndrome.
