Constipation Nursing Care Plan and Diagnosis

In a nursing care plan, constipation is addressed by identifying why the patient's bowel movements have become infrequent, hard or difficult to pass, setting measurable goals for bowel elimination and choosing interventions such as increasing fiber and fluids, getting the patient moving, building a toileting routine and giving laxatives as prescribed. The plan rests on a thorough bowel assessment, including stool form on the Bristol Stool Form Scale, and on finding the cause, which in hospital is often opioids, immobility and low intake.

This guide explains which constipation nursing diagnosis label to use under NANDA-I 2024–2026, how to assess bowel function, which bowel elimination interventions have guideline support, the red flags that need escalation, and a complete care plan example.

What Counts as Constipation

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) describes constipation as having fewer than three bowel movements a week, stools that are hard, dry or lumpy, stools that are difficult or painful to pass, or a feeling that not all stool has passed. NIDDK estimates that about 16 in 100 U.S. adults have symptoms, rising to about 1 in 3 adults aged 60 and older. It also notes that constipation is a symptom, not a disease, so your plan should look for the cause.

For chronic functional constipation, clinicians use the Rome IV criteria (Mearin and colleagues, 2016). The patient must have at least two of the following: straining, lumpy or hard stools, a sense of incomplete emptying, a sense of blockage, or the need for manual maneuvers in more than a quarter of bowel movements, or fewer than three spontaneous bowel movements a week. Symptoms must be present for the last three months, starting at least six months before diagnosis, and the patient should not meet the criteria for irritable bowel syndrome. Most constipation you see on a hospital unit is acute rather than chronic, but knowing the criteria helps you describe what you find.

Constipation Nursing Diagnosis: Which NANDA-I Label to Use

For years the standard label was Constipation, with Risk for constipation for patients who had not yet developed it. In the NANDA-I 2024–2026 edition, the gastrointestinal function class (Domain 3, Elimination and exchange) lists Impaired intestinal elimination and Risk for impaired intestinal elimination as the general labels, alongside Chronic functional constipation, Risk for chronic functional constipation and Impaired gastrointestinal motility. The older Constipation label does not appear as a separate diagnosis in that edition.

Many nursing programs, textbooks and electronic health records still use Constipation, so check which edition your instructor expects. Whichever label you use, the logic is the same:

• Problem-focused: the patient already has constipation. Write it with the related factors and the evidence. For example: "Impaired intestinal elimination related to opioid use and reduced mobility, as evidenced by no bowel movement for four days, hard lumpy stool (Bristol type 1) and straining."
• Risk: the patient does not have it yet but is likely to. For example: "Risk for impaired intestinal elimination related to new opioid therapy, bed rest and poor oral intake after surgery."
• Chronic functional constipation: long-standing symptoms that meet criteria like Rome IV, usually in outpatient or long-term care settings.

If you are still learning how to structure these statements, our guide to nursing diagnosis examples and PES statements covers the format, and our list of common nursing diagnoses shows where elimination diagnoses fit among the 13 NANDA-I domains.

Nursing Assessment for Constipation

A good care plan starts with a bowel history and a focused abdominal exam. Ask about and record:

• The patient's usual bowel pattern and the date of the last bowel movement
• Stool form using the Bristol Stool Form Scale, plus straining, pain or a sense of incomplete emptying
• Fluid and fiber intake, appetite and any nausea
• Mobility and whether the patient can reach the toilet independently
• Medications, including opioids, iron, calcium channel blockers, anticholinergics, some antidepressants and aluminum or calcium antacids, all of which NIDDK lists as possible causes
• Laxative use at home, since long-term users may need a planned approach

On examination, inspect the abdomen for distension, listen for bowel sounds, percuss for dullness over stool-filled bowel and palpate gently for tenderness or masses. Record intake and output. A digital rectal exam to check for impaction is performed only within your scope and facility policy, usually on a provider's order. If you are building the assessment into a larger exam, see our head-to-toe assessment guide.

Using the Bristol Stool Form Scale

The Bristol Stool Form Scale describes stool in seven types. Lewis and Heaton showed in a 1997 study of 66 volunteers that stool form tracked whole-gut transit time better than bowel movement frequency did, and that it changed in the expected direction when transit was sped up with senna or slowed with loperamide. That makes it a practical way to monitor whether your interventions are working.

Types 1 and 2 are the hard or lumpy stools that the Rome IV criteria count toward constipation and suggest slow transit. Types 6 and 7 are loose. Types 3 to 5 sit between them. Documenting the type at each bowel movement is more useful than writing "small BM," because it shows whether stool is softening over time.

Causes and Risk Factors in Hospitalized Patients

NIDDK groups causes into diet and lifestyle, medications, changes in routine and underlying conditions. In hospital, several usually stack up at once:

• Opioids and other constipating drugs, especially after surgery
• Immobility from bed rest, pain, weakness or attached equipment
• Low intake of food, fiber and fluid, including periods of fasting before procedures
• Loss of routine and privacy, such as using a bedpan in a shared room or delaying when the urge comes
• Underlying conditions such as hypothyroidism, diabetes, Parkinson's disease, spinal cord injury or dehydration
• Age, since older adults are more likely to have several of these factors together

Bowel Elimination Interventions with Rationales

Fiber, Fluids and Food

NIDDK advises that adults get 22 to 34 grams of fiber a day, depending on age and sex, and that fiber be added a little at a time so the body can adjust. It also recommends drinking plenty of liquids so the fiber can work. The Dietary Guidelines for Americans, 2025–2030 give serving goals of 2 to 4 servings of whole grains, 3 servings of vegetables and 2 servings of fruit a day for a 2,000-calorie pattern, and name water (still or sparkling) and unsweetened drinks as the preferred beverages.

Always check for fluid restrictions before encouraging fluids. Patients with heart failure or advanced kidney disease may have a daily limit, and fiber works best when fluid intake is adequate. A dietitian referral helps when intake is poor or restrictions are complex.

Mobility, Routine and Positioning

• Encourage activity as tolerated, from walking in the hallway to bed exercises. NIDDK notes that regular physical activity may help relieve symptoms.
• Use the gastrocolic reflex. NIDDK suggests trying to have a bowel movement 15 to 45 minutes after breakfast, when eating stimulates colon activity. Offer the toilet or commode at that time.
• Respond to the urge. Answer call lights promptly so patients do not have to delay.
• Position for success. A bedside commode or toilet is easier than a bedpan. Resting the feet on a footstool can make emptying easier, as NIDDK's treatment guidance suggests.
• Provide privacy and enough time.

Medications

Laxatives are given on a provider's order or according to an approved protocol. The 2023 AGA-ACG guideline on chronic idiopathic constipation made strong recommendations for polyethylene glycol and sodium picosulfate, and conditional recommendations for fiber, senna, magnesium oxide and lactulose, with prescription options for patients who do not respond. In practice, your role is to give what is ordered, monitor the effect using stool type and frequency, watch for cramping, diarrhea and electrolyte problems, and report when the regimen is not working. When a patient starts regular opioids, ask the prescriber whether a preventive bowel regimen should be ordered rather than waiting for constipation to develop. Magnesium-based laxatives need caution in kidney impairment, so flag that history to the prescriber.

Red Flags That Need Escalation

Constipation is common, but it can also signal something serious. NIDDK advises urgent medical review when constipation comes with rectal bleeding or blood in the stool, constant abdominal pain, inability to pass gas, vomiting, fever, lower back pain or unintentional weight loss. On a hospital unit, also report promptly:

• A distended, firm or tender abdomen with absent or high-pitched bowel sounds, which may point to obstruction or ileus
• Liquid stool leaking around hard stool, which can be overflow from fecal impaction rather than diarrhea
• New confusion, agitation or urinary retention in an older adult who has not had a bowel movement
• No bowel movement despite the ordered regimen, especially on opioids

When you call the provider, a structured report such as SBAR keeps the key findings clear: last bowel movement, stool type, abdominal findings, vital signs and what has been given.

Nursing Care Plan Constipation Example

For example, take a hypothetical 72-year-old man on day three after a total hip replacement. He takes oxycodone every four to six hours for pain, has not had a bowel movement for four days (his usual pattern is daily), reports a full, uncomfortable abdomen and passed a small type 1 stool with straining this morning. Bowel sounds are present but hypoactive, his abdomen is mildly distended and soft, and he is drinking about 1 liter a day. He has no fluid restriction.

Compare this with our acute pain nursing care plan. Postoperative patients often need both, and the two plans should not work against each other: good pain control helps mobility, while the opioids that provide it slow the bowel.

Tips for Writing a Strong Constipation Care Plan

• Name the cause. "Related to opioid use and immobility" leads to specific interventions. "Related to constipation" does not.
• Use measurable evidence. Days since the last bowel movement, Bristol type and abdominal findings are better than "patient is constipated."
• Make outcomes time-bound. Give a time frame such as 24 or 48 hours and a target stool type.
• Check restrictions before you write "increase fluids." State the target amount and confirm it fits the patient's orders.
• Include red flags and when you will escalate, not just comfort measures.
• Evaluate with the same measures you used in the assessment, so your instructor can see whether the goal was met.

Getting Help with Your Care Plan

Elimination care plans are common in fundamentals and medical-surgical courses, and instructors often look for a clear link between the cause, the interventions and the evaluation.

Frequently Asked Questions

What Is the Nursing Diagnosis for Constipation?

Many programs still use the NANDA-I label Constipation. In the 2024–2026 edition, the general labels are Impaired intestinal elimination and Risk for impaired intestinal elimination, with Chronic functional constipation for long-standing cases. Ask which edition your instructor follows.

What Are the Main Nursing Interventions for Constipation?

Assess bowel pattern and stool type, increase fiber gradually, encourage fluids unless restricted, promote mobility, offer the toilet after meals with privacy, give ordered laxatives and monitor their effect, and teach the patient how to prevent a recurrence.

How Much Fiber Should Adults Eat for Constipation?

NIDDK recommends 22 to 34 grams of fiber a day for adults, depending on age and sex. Increase it slowly and drink enough fluid so the fiber can soften the stool.

What Bristol Stool Type Means Constipation?

Types 1 and 2, separate hard lumps or a lumpy sausage shape, are the hard stools associated with constipation and slow transit. Types 6 and 7 are loose.

When Should a Nurse Escalate Constipation?

Report promptly if the patient has vomiting, severe or constant abdominal pain, a distended firm abdomen, cannot pass gas, has blood in the stool, fever or liquid stool leaking around hard stool, or if the ordered regimen has not worked.

Should Every Patient on Opioids Have a Constipation Care Plan?

Opioids commonly cause constipation, so many patients on regular opioids benefit from a risk diagnosis and a preventive bowel regimen discussed with the prescriber. Base the decision on your assessment and your facility's protocols.
