    Study Notes

    Constipation and Diarrhea

    • Lack of fiber, dehydration, and physical inactivity are primary causes of constipation.
    • A lifestyle characteristic that can contribute to constipation is a low-fiber diet.
    • The recommended daily dietary fiber intake for women aged 51 or older is at least 22 grams.
    • Exercise contributes to proper bowel function by stimulating the muscles in the intestines and improving the movement of food through the digestive system.
    • The stomach is responsible for secreting acid and enzymes to continue the process of digestion of food to a liquid/paste texture.
    • The duodenum, the first part of the small intestine, is responsible for the continuous process of breaking down food.
    • The liver produces and secretes bile, which is important for lipid metabolism.
    • The colon, also known as the large intestine, connects the cecum to the rectum and is responsible for removing water from undigested material.
    • A common symptom of opioid-induced constipation is infrequent bowel movements or hard, dry stools.
    • Diarrheal disease is the second leading cause of death in children under 5 worldwide.
    • The prevalence rate of diarrheal disease in older adults (ages 65 years and older) is 7.3%.
    • Approximately 1.6 million deaths are caused annually by diarrheal disease.
    • The pelvic floor is the anatomical region associated with constipation.
    • The process of defecation is a complex process involving the coordinated effort of the muscles, nerves, and organs in the digestive system.
    • Symptoms of constipation include infrequent bowel movements, hard, dry stools, and straining during bowel movements.
    • Older adults, pregnant women, and individuals with a low-fiber diet are at a higher risk of experiencing constipation.
    • Straining during bowel movements is a symptom of constipation.
    • Viral infections, such as norovirus, are a cause of acute diarrhea.
    • Rotavirus is the most common cause of severe gastroenteritis in infants and young children worldwide.
    • Salmonella is a common pathogen causing bacterial gastroenteritis.
    • Salmonella is responsible for the majority of cases of bacterial gastroenteritis.
    • Hemolytic uremic syndrome (HUS) is not a potential complication of food-borne gastroenteritis.
    • Vibrio is not commonly associated with traveler's diarrhea.
    • One mechanism that can induce food-induced diarrhea is an increased permeability of the intestinal epithelium.
    • Children under 5 years old are at greater risk for complications from diarrheal illness.
    • Signs and symptoms of dehydration associated with diarrheal disease include dry mouth, dark urine, and decreased urine output.
    • The cholera toxin directly stimulates GI secretomotor neurons to increase intestinal secretion.
    • The major complication of diarrheal illness is dehydration.
    • Viruses play a role in the pathophysiology of diarrhea by causing inflammation and damaging the intestinal epithelium.
    • The mechanisms associated with stool clearance include the contraction of intestinal muscles and the relaxation of the internal anal sphincter.
    • The colon, also known as the large intestine, is responsible for removing water from undigested material.

    Gastroenteritis

    • Norovirus is the most common cause of gastroenteritis in the United States.
    • The prevalence rate of diarrheal disease in children under 5 years in the United States is 1.3%.
    • The leading cause of death in children under 5 worldwide is pneumonia.
    • The liver produces and secretes bile, which is important for lipid metabolism.
    • The jejunum, the middle part of the small intestine, is responsible for the absorption of nutrients into the bloodstream.
    • The pancreas is responsible for the endocrine function of releasing hormones directly into the bloodstream.
    • The rectum is responsible for storing stool until it is emptied into the rectum.
    • A potential symptom of severe dehydration is decreased urine output.
    • Children under 5 years old are at the greatest risk for complications from diarrheal illness.
    • Bacterial enterotoxins play a role in secretory diarrhea by stimulating the secretion of ions and water into the intestine.
    • A potential cause of secretory diarrhea is a bacterial infection.
    • E. coli is the most common cause of traveler's diarrhea.
    • Hemolytic uremic syndrome (HUS) is not a potential complication of food-borne gastroenteritis.
    • Salmonella is responsible for the majority of cases of bacterial gastroenteritis.
