Constipation, characterized by infrequent bowel movements and difficulty passing stools, is a prevalent gastrointestinal issue affecting a wide range of individuals. It’s typically defined by a decrease in the normal frequency of bowel movements, often accompanied by stools that are hard, dry, and difficult to pass. While constipation can affect anyone, certain populations are more susceptible.
Who is at Risk for Constipation?
- Older Adults: Age-related factors such as reduced physical activity, slower metabolism, and decreased muscle strength in the digestive tract contribute to constipation in the elderly.
- Women (Especially During and After Pregnancy): Hormonal fluctuations, particularly during pregnancy and postpartum, can disrupt bowel regularity. Furthermore, the growing fetus can exert pressure on the intestines, slowing down stool passage.
- Individuals with Neurological Conditions: Certain neurological diseases can impair bowel function and increase the risk of constipation.
Note on Terminology: It’s important to acknowledge that the nursing diagnosis “Constipation” has been updated to “Chronic Functional Constipation” by the NANDA International Diagnosis Development Committee (DDC). While the official terminology is evolving, this article will continue to use the term “Constipation” for broader recognition and understanding, until the updated label gains widespread adoption in clinical practice and education.
Causes of Constipation (Etiology)
Constipation can arise from a multitude of factors, often stemming from lifestyle, dietary habits, medications, or underlying health conditions. Understanding these causes is crucial for effective nursing assessment and intervention.
Dietary Factors:
- Low Fiber Intake: Insufficient dietary fiber reduces stool bulk, making it harder to pass. Fiber, found in fruits, vegetables, and whole grains, adds bulk to the stool and aids in smooth bowel movements.
- High Consumption of Dairy Products: Excessive intake of milk and cheese can contribute to constipation in some individuals, potentially due to their low fiber content and effects on gut motility.
- Processed Foods: Diets rich in highly processed foods are often low in fiber and can lead to constipation. These foods are typically devoid of the natural fiber found in whole, unprocessed foods.
- Dehydration: Inadequate fluid intake can lead to dry, hard stools, exacerbating constipation. Water is essential for maintaining stool consistency and facilitating bowel movements.
Activity and Lifestyle:
- Sedentary Lifestyle: Lack of physical activity slows down metabolism and bowel motility, increasing the risk of constipation. Regular exercise promotes healthy bowel function.
- Changes in Routine: Disruptions to daily routines, such as travel or changes in work schedules, can affect bowel habits and lead to constipation.
- Limited Mobility: Conditions causing bed rest or poor mobility significantly reduce physical activity and contribute to constipation.
- Ignoring the Urge to Defecate: Habitually suppressing the urge to have a bowel movement can lead to constipation over time. The longer stool sits in the colon, the drier and harder it becomes.
Psychological and Social Factors:
- Stress: Stress and anxiety can impact bowel function and contribute to constipation in some individuals. The gut-brain connection plays a significant role in digestive health.
- Oral/Dental Health Problems: Dental issues that make chewing difficult can lead to a preference for softer, low-fiber foods, increasing constipation risk.
Physiological and Medical Factors:
- Pregnancy and Postpartum: Hormonal changes and physical pressure from the fetus during pregnancy, as well as postpartum recovery, can lead to constipation.
- Chronic Pain: Chronic pain conditions may lead to reduced physical activity and medication use, both of which can contribute to constipation.
Medications:
- Pain Medications:
- Narcotics (Opioids): Opioid analgesics are notorious for causing constipation by slowing down bowel motility.
- Nonsteroidal Anti-inflammatory Drugs (NSAIDs): While less constipating than opioids, NSAIDs can still contribute to constipation in some individuals.
- Antidepressants: Certain antidepressants can have anticholinergic effects, which can slow down bowel movements and lead to constipation.
- Antacids (Calcium or Aluminum-Based): Antacids containing calcium or aluminum can be constipating.
- Iron Supplements: Iron supplements are a common cause of constipation.
- Allergy Medications (Antihistamines): Some antihistamines have anticholinergic effects that can contribute to constipation.
- Certain Blood Pressure Medications: Certain antihypertensive medications can have constipation as a side effect.
- Psychiatric Medications: Some psychiatric medications can also contribute to constipation.
- Antiemetics: Medications used to prevent vomiting may sometimes cause constipation.
- Anticonvulsants: Certain anticonvulsant medications can have constipation as a side effect.
Underlying Medical Conditions:
- Various medical conditions and diseases can contribute to constipation, requiring thorough medical evaluation to identify and address the root cause.
Signs and Symptoms of Constipation (Defining Characteristics)
Recognizing the signs and symptoms of constipation is crucial for accurate nursing assessment. These can be categorized into subjective reports from the patient and objective findings assessed by the nurse.
Subjective Data (Patient Reports):
- Infrequent Bowel Movements: Reporting fewer than three bowel movements per week is a primary indicator of constipation.
- Hard or Dry Stools: Patients may describe their stools as hard, dry, and difficult to pass.
- Lumpy Stools: Stools that are lumpy and resemble pebbles or nuts are indicative of constipation.
- Straining During Bowel Movements: Significant straining, pain, or difficulty when attempting to pass stool.
- Abdominal Discomfort: Stomach pain, aches, cramps, or general abdominal discomfort.
- Bloating and Nausea: A sensation of bloating, fullness, or nausea may accompany constipation.
- Incomplete Evacuation: The feeling that the bowels are not fully emptied after a bowel movement.
Objective Data (Nurse Assessment):
- Medical History Review: Assess the patient’s medical history for pre-existing constipation, activity levels, and medications known to cause constipation.
- Abdominal Pain Assessment: Utilize an age-appropriate pain scale to assess abdominal pain, noting:
- Location: Where is the pain located in the abdomen?
- Severity: How intense is the pain?
- Duration: How long has the pain been present?
- Description: What does the pain feel like (e.g., sharp, cramping, dull)?
- Aggravating/Relieving Factors: What makes the pain worse or better?
- Comprehensive Abdominal Assessment: Perform a systematic abdominal assessment in the following order:
- Inspection: Observe the abdomen for distension, visible peristalsis, or scars.
- Auscultation: Listen for bowel sounds in all four quadrants. Note the frequency and character of bowel sounds (hypoactive, hyperactive, absent).
- Percussion: Percuss the abdomen to assess for tympany (air-filled) or dullness (fluid or solid).
- Palpation: Gently palpate the abdomen to assess for tenderness, masses, or organomegaly.
- Stool Characteristics Assessment: Evaluate stool characteristics based on patient report and, when possible, direct observation:
- Color: Note the color of the stool (e.g., brown, black, red, clay-colored).
- Consistency: Assess stool consistency (hard, soft, liquid). Utilize the Bristol Stool Chart for standardized assessment.
- Amount: Estimate the amount of stool passed.
Expected Outcomes for Constipation Management
Setting realistic and measurable expected outcomes is essential for guiding nursing care and evaluating its effectiveness. For patients with constipation, common expected outcomes include:
- Soft, Formed Stool: Patient will report passing soft, formed stools during bowel movements, indicating improved stool consistency and ease of passage.
- Regular Bowel Movements: Patient will establish a bowel movement frequency within the range of three times per week to three times per day, reflecting improved bowel regularity.
- Pain-Free Bowel Movements: Patient will verbalize being free of pain and straining during bowel movements, demonstrating improved comfort and ease of defecation.
- Knowledge of Prevention: Patient will be able to identify actions to prevent constipation in the future, indicating effective patient education and self-management skills.
- Lifestyle Modifications: Patient will be able to enumerate behavior or lifestyle changes to prevent constipation, showing an understanding of necessary long-term changes for bowel health.
Nursing Assessment for Constipation
A thorough nursing assessment is the cornerstone of effective care for constipation. It involves gathering both subjective and objective data to understand the patient’s bowel habits, contributing factors, and overall health status.

13. Assist with Imaging Studies: Prepare and assist the patient with imaging tests as ordered to rule out underlying causes of constipation.
Nursing Interventions for Constipation
Nursing interventions are crucial for alleviating constipation and promoting regular bowel function. These interventions encompass a range of strategies, from manual techniques to lifestyle modifications and medication management.
1. Manual Disimpaction: For fecal impaction, manual disimpaction may be necessary. This involves the gentle digital removal of stool from the rectum. Transrectal enemas may also be used.
2. Administer Laxatives or Stool Softeners as Prescribed: Medications can be helpful in the short term to initiate bowel movements. Types of laxatives and stool softeners include:
- Bulk-forming agents (Fiber, Psyllium): Increase stool bulk and promote natural peristalsis.
- Emollient Stool Softeners (Docusate): Soften stool by increasing water and fat content.
- Rapidly Acting Lubricants (Mineral Oil): Lubricate the stool and intestinal walls for easier passage.
- Prokinetics (Tegaserod): Stimulate bowel motility (use limited due to potential side effects and availability).
- Stimulant Laxatives (Senna, Bisacodyl): Stimulate bowel contractions to promote defecation (should be used cautiously and not for long-term management).
3. Apply Lubricant or Anesthetic Ointment: For painful defecation, lubricant or anesthetic ointment can be applied to the perianal area to facilitate stool passage and reduce discomfort.
4. Emphasize Lifestyle Changes: Patient education is paramount, focusing on long-term constipation prevention through lifestyle modifications rather than sole reliance on medications. Key lifestyle changes include:
- Dietary Modifications: Increasing fiber intake and ensuring adequate hydration.
- Regular Physical Activity: Incorporating exercise into daily routine.
- Establishing Regular Bowel Habits: Responding to the urge to defecate and establishing a consistent toileting schedule.
5. Encourage a High-Fiber Diet: Promote a diet rich in fiber from whole foods and fiber supplements:
- Whole Foods: Fruits, vegetables, and whole grains are excellent sources of fiber.
- Fiber Supplements: Wheat bran and psyllium supplements can increase fiber intake.
- Fiber-Rich Foods Examples:
- Fruits: Raspberries, strawberries, blueberries, pears, apples, bananas.
- Vegetables: Peas, broccoli, Brussels sprouts, potatoes, sweet corn, cauliflower, carrots.
- Grains: Barley, quinoa, bran, oatmeal, brown rice, whole wheat bread.
- Legumes and Nuts: Split peas, lentils, baked beans, black beans, chia seeds.
- Limit Low-Fiber, High-Fat Foods: Reduce intake of ice cream, cheese, meats, processed meals, and fast food, which are low in fiber and can contribute to constipation.
6. Promote Increased Fluid Intake: Encourage adequate daily fluid intake, prioritizing:
- Water: The most essential fluid for hydration and stool softening.
- High-Fiber Fruits: Fruits with high water content and fiber.
- Vegetable Juices: Provide hydration and some fiber.
- Fruit and Vegetable Smoothies: Combine fluids and fiber.
- Popsicles: Contribute to fluid intake, especially for patients with difficulty drinking.
- Warm Liquids: Tea, hot water, or decaffeinated coffee can stimulate bowel movements for some individuals.
7. Avoid Caffeine and Alcohol: Advise limiting or avoiding caffeine and alcohol, as they can dehydrate the body and irritate the gastrointestinal tract.
8. Advise Physical Activity: Encourage daily exercise and physical activity to improve bowel motility and overall health.
9. Encourage Elimination Diary: Suggest keeping an elimination diary to track bowel movements, stool characteristics, and medication use, which can aid in long-term management.
10. Establish Regular Bowel Movements: Encourage patients to respond to the urge to defecate and establish a predictable toileting schedule. For patients with colostomies, promote regular irrigation.
11. Promote Bowel Management Program: Create a consistent bowel management program, ensuring privacy and preferred toileting methods (toilet, commode, bedpan).
12. Promote Pain Relief During Defecation: Recommend a sitz bath before bowel movements to relax the anal sphincter and reduce pain.
13. Apply Gentle Abdominal Massage: Perform gentle abdominal massage following the direction of the colon to stimulate bowel movements.
14. Teach Abdominal Massage Techniques: Instruct patients on how to perform abdominal massage at home for self-management.
15. Refer to Healthcare Provider for Medical Therapies: Advise patients to consult their healthcare provider before using additional medical therapies (laxatives, enemas, suppositories) to prevent misuse and ensure appropriate treatment.
16. Assist with Surgical Interventions: In rare cases of severe, intractable constipation, surgery may be necessary. Surgical options include:
- Anal Procedures: Procedures to address structural issues in the anal canal.
- Antegrade Enemas: Surgical placement of a tube to administer enemas directly into the colon.
- Colorectal Resection: Surgical removal of a portion of the colon.
- Intestinal Diversion: Creating an ostomy to divert stool.
17. Sacral Nerve Stimulation: Sacral nerve stimulation may be considered for some individuals with chronic functional constipation, but further research is ongoing.
18. Provide Emotional Support: Offer ongoing emotional support and assistance to patients dealing with the challenges of chronic bowel control issues.
Nursing Care Plans for Constipation
Nursing care plans provide a structured framework for organizing and delivering patient care. Here are examples of nursing care plans for constipation, focusing on different related factors.
Care Plan #1: Opioid-Induced Constipation
Diagnostic Statement: Constipation related to opioid analgesics as evidenced by lack of bowel movement post-surgery.
Expected Outcomes:
- Patient will pass soft, formed stools every 1 to 3 days without straining.
- Patient will implement measures to relieve opioid-induced constipation.
Assessment:
- Review Medication History: Determine if the patient is taking opioid analgesics and the dosage. Opioid-induced constipation is common in patients taking opioids for pain relief.
- Assess Normal Defecation Pattern: Establish the patient’s usual bowel habits to identify deviations. Utilize Rome IV Criteria for functional constipation if needed:
- Hard stools at least 25% of the time.
- Straining at least 25% of the time.
- Feeling of incomplete evacuation at least 25% of the time.
- Manual maneuvers to facilitate defecation.
Interventions:
- Administer Laxatives as Indicated: Prophylactic laxatives (excluding bulk-forming agents initially) are typically prescribed for patients on opioids.
- Encourage Early Mobility: Promote early ambulation post-surgery to stimulate bowel function and reduce postoperative complications.
- Educate Patient and Family: Explain that constipation is a common side effect of opioids and can be managed with laxatives (stimulant, stool softener, osmotic) and physical activity.
- Discourage Long-Term Laxative Use: Advise against prolonged use of stimulant laxatives to prevent dependence.
Care Plan #2: Immobility-Related Constipation
Diagnostic Statement: Constipation related to immobility as evidenced by bloating and abdominal discomfort.
Expected Outcomes:
- Patient will pass Bristol Stool Chart Type 3 or 4 stools (indicating improved consistency).
- Patient will report relief from constipation discomfort (bloating, abdominal pain, distension, anorexia, nausea, vomiting).
- Patient will demonstrate methods to alleviate constipation discomfort.
Assessment:
- Assess Usual Bowel Pattern: Gather detailed information about the patient’s typical bowel habits, including frequency, consistency, laxative use, diet, exercise, and fluid intake.
- Assess Mobility Level: Evaluate the patient’s current mobility status to tailor appropriate interventions.
Interventions:
- Advise High-Fiber Diet (18-25g daily): Recommend fiber-rich foods like prune juice, leafy greens, whole grains to increase stool bulk and stimulate peristalsis.
- Advise Adequate Fluid Intake (1.5-2L daily): Unless contraindicated, encourage 6-8 glasses of water daily to soften stool and promote lubrication.
- Encourage Physical Activity: Promote mobility within the patient’s limitations. For immobile patients, encourage in-bed exercises like turning, position changes, knee-to-chest raises, and gentle stretching.
- Demonstrate Abdominal Massage: Teach gentle abdominal massage in the direction of colon flow, potentially using aromatherapy oils, to increase intra-abdominal pressure and stimulate bowel sensation.
- Perform Enemas or Disimpaction: Consider enemas if other interventions are ineffective to cleanse and stimulate bowel emptying.
Care Plan #3: Diet-Related Constipation
Diagnostic Statement: Constipation related to poor diet habits as evidenced by straining to have bowel movements and less than three stools a week.
Expected Outcomes:
- Patient will maintain passage of soft, formed stool without straining.
- Patient will identify measures to prevent or treat constipation.
Assessment:
- Review Dietary Regimen: Assess daily diet for fiber deficiency and high intake of processed foods.
- Note Oral/Dental Health: Identify dental issues that may limit fiber intake due to difficulty chewing.
- Determine Fluid Intake: Assess fluid intake to identify potential dehydration.
Interventions:
- Discuss Laxative and Enema Use: Educate that these are not long-term solutions and lifestyle changes are crucial.
- Identify Bowel Activity Stimulants: Discuss factors that stimulate bowel movements (caffeine, walking, laxatives) and factors that precipitate constipation (opioids, immobility, surgery).
- Promote Lifestyle Changes:
- High-Fiber Diet: Encourage a diet rich in fruits, vegetables, and whole grains, or fiber supplements if needed.
- Limit Low-Fiber, High-Fat Foods: Reduce intake of processed foods, fast food, meats, cheese, and ice cream.
- Adequate Fluid Intake: Promote water, fruit/vegetable juices, and smoothies.
- Warm Liquids: Suggest warm drinks like decaffeinated coffee, tea, or hot water.
- Daily Exercise: Encourage physical activity within individual limits.
- Regular Toileting Schedule: Advise against ignoring the urge to defecate and establish a routine.
- Encourage Sitz Baths: Recommend sitz baths to relax the sphincter and provide soothing relief.
