Elderly Constipation & Faecal Impaction: When a Quiet Problem Becomes a Hospital Visit
It's the topic nobody wants to discuss with their parent — or hear about. But constipation is one of the most common, most under-recognised, and most consequential health problems in older Australians. 50–65% of people over 65 experience chronic constipation, and untreated, it leads to faecal impaction — a hard plug of stool that the bowel cannot pass.
Faecal impaction in elderly people causes delirium, urinary retention, sepsis, bowel perforation, and emergency hospital admission. Yet it's entirely preventable. This guide covers what causes it (medications top the list), the warning signs that families miss, when to call the GP, and how daily wellness check-in calls can monitor bowel patterns without making the conversation awkward.
Constipation in Older Australians
Of over-65s have chronic constipation
Hospital presentations annually
Cause: medications (especially opioids)
Trigger of acute delirium
What Causes Constipation in Elderly People
Medications (the biggest cause)
Opioids (oxycodone, codeine, tramadol), iron supplements, anticholinergics (oxybutynin, amitriptyline), calcium channel blockers, antacids, certain antidepressants. Polypharmacy compounds the effect.
Inadequate fluid intake
Reduced thirst sensation in elderly. Many drink <1L/day. Hard stool can't form without water.
Low fibre diet
Living alone, often eating processed foods, white toast, tea-and-toast pattern. Fruit and vegetables drop off.
Reduced mobility
Walking stimulates bowel motility. Sitting all day allows bowel motions to slow.
Hypothyroidism, diabetes, Parkinson's
All slow gut motility. Common in elderly.
Ignoring the urge
Mobility issues mean it's hard to get to the toilet quickly. Repeatedly delaying eventually deadens the urge.
Warning Signs Families Often Miss
Direct Symptoms
- • No bowel motion in 3+ days
- • Hard, lumpy, painful stools
- • Straining
- • Sensation of incomplete emptying
- • Bloating, abdominal discomfort
- • Reduced appetite
Confusing “Atypical” Symptoms
- • Sudden confusion (delirium)
- • Liquid stool leaking (overflow diarrhoea around impaction — commonly mistaken for diarrhoea)
- • Urinary retention (impaction presses on bladder)
- • Reduced mobility — “just feels off”
- • Falls without explanation
- • Mild low-grade fever
- • Restless agitation
The Delirium Connection
In elderly people, faecal impaction is one of the top 5 reversible causes of acute delirium. A confused parent who hasn't opened bowels in a week often turns out to have impaction — and clears completely once the impaction is removed. Always ask about bowels in any unexplained confusion.
Treatment: Stepwise Approach
| Step | Approach |
|---|---|
| 1. Lifestyle | 2L water/day, fibre (oats, prunes, kiwi fruit), walking 30 min/day |
| 2. Bulk-forming laxatives | Psyllium husk, methylcellulose — safe long-term |
| 3. Osmotic laxatives | Movicol, Lactulose — safe daily, work in 1–3 days |
| 4. Stimulants | Senna, bisacodyl — short-term use only |
| 5. Suppositories or enemas | For acute episodes when pills don't work |
| 6. Manual disimpaction | By district nurse if impaction confirmed |
| 7. Hospital | If signs of obstruction, perforation, or sepsis |
When to Call the GP — or 000
GP Same Day
- • No bowel motion in 5+ days
- • Sudden confusion + constipation
- • Liquid leakage suggesting overflow
- • Persistent abdominal pain
- • Vomiting + constipation
- • New blood in stool
000 / Emergency Department
- • Severe abdominal pain & rigid abdomen
- • Vomiting + no flatus
- • Fever + abdominal pain (perforation/sepsis)
- • Loss of consciousness or severe confusion
- • Distended belly + breathlessness
How Daily Calls Help
A daily call is one of the few comfortable ways to track bowel patterns without an awkward conversation every day. The caller can ask “how's your tummy been today?” or “everything moving OK?” and family alerts trigger if patterns suggest constipation.
- • Sudden mood/cognitive change (delirium red flag)
- • Bloating or abdominal discomfort mentioned
- • Reduced appetite reported
- • Reduced fluid intake confirmed
- • Pattern of no bowel motion mentioned across days
- • New report of nausea or vomiting
