Comparison of Bowel Elimination Disorders
Diarrhea
Pathophysiology: Diarrhea is characterized by frequent loose or liquid stools, which occur due to excessive fluid and electrolyte secretion or decreased absorption in the intestine. Infection, inflammation, malabsorption, and certain medications can cause diarrhea (Ignatavicius et al., 2020).
Etiology: Diarrhea can be caused by viral or bacterial infections, such as rotavirus or E. coli, inflammatory bowel disease, lactose intolerance, celiac disease, certain medications, and radiation therapy (Ignatavicius et al., 2020).
Clinical Manifestations: Diarrhea can cause dehydration, electrolyte imbalance, and malnutrition. Common symptoms include frequent watery stools, abdominal cramping, bloating, nausea, and fever (Ignatavicius et al., 2020).
Interventions:
- Monitor fluid and electrolyte balance by measuring intake and output, serum electrolytes, and weight.
- Reassess stool frequency, consistency, and color, and monitor for signs of dehydration, such as dry mucous membranes, poor skin turgor, and decreased urine output.
- Teach the patient to maintain adequate hydration by drinking clear liquids, such as water, broth, and electrolyte solutions, and avoid caffeine, alcohol, and sugary drinks.
- Administer antidiarrheal medications, such as loperamide or diphenoxylate/atropine, as prescribed to decrease intestinal motility and relieve symptoms (Ignatavicius et al., 2020).
Bowel Obstruction
Pathophysiology: Bowel obstruction occurs when the passage of intestinal contents is partially or completely blocked by a physical barrier, such as a tumor, adhesion, or hernia. This can cause intestinal distention, inflammation, and ischemia, leading to fluid and electrolyte imbalances and bacterial overgrowth (Ignatavicius et al., 2020).
Etiology: Bowel obstruction can be caused by mechanical factors, such as tumors, adhesions, hernias, or impacted feces, or functional factors, such as intestinal paralysis or neuropathy (Ignatavicius et al., 2020).
Clinical Manifestations: Bowel obstruction can cause abdominal pain, cramping, bloating, vomiting, and constipation or diarrhea, depending on the location and severity of the obstruction. Signs of intestinal obstruction include high-pitched bowel sounds, abdominal distention, and visible peristaltic waves (Ignatavicius et al., 2020).
Interventions:
- Monitor vital signs, including blood pressure, pulse, respiratory rate, and temperature, to detect signs of dehydration, sepsis, or shock.
- Reassess abdominal distention, bowel sounds, and passage of gas and stool, and monitor for signs of strangulation, such as fever, abdominal tenderness, or bloody stool.
- Teach the patient to maintain bowel rest, avoid oral intake, and receive parenteral nutrition and fluids as prescribed. Prepare the patient for possible surgery or endoscopic procedures to relieve the obstruction (Ignatavicius et al., 2020).
Hemorrhoids
Pathophysiology: Hemorrhoids are swollen and inflamed veins in the rectum or anus, which can be internal or external. Increased pressure in the rectal area, such as during constipation, pregnancy, or prolonged sitting,
