Constipation is common in people living with disability and can significantly affect comfort, dignity, appetite and quality of life. Good bowel management starts with the basics: adequate fluid, varied fibre, movement where possible and a consistent toileting routine. However, constipation is not always a nutrition problem — medications, reduced mobility and the disability itself can all contribute.
Why is constipation common in disability?
There is often more than one reason. Permanent disabilities such as cerebral palsy can affect muscle tone, abdominal strength, mobility and positioning, making bowel movements more difficult. Medications can also slow the bowel, so it is important to consider whether constipation started or worsened after a medication change. Reduced mobility is another common contributor, as someone who spends much of their day sitting or lying down may not get the natural movement that helps stimulate digestion and bowel activity. This is why constipation should be approached as a whole-person issue, not simply “they need more fibre”.
What should we check first?
Start with the basics: fluid, fibre and movement.
1. Fluid
For many adults, around 2 litres of fluid per day is a useful general target, although individual needs vary. In practice, we often see plenty of fluids being offered, but very little actually being consumed. A water bottle beside someone’s chair is not helpful if they cannot open it, reach it or remember to drink it. Offer fluids regularly throughout the day and with meals.
2. Fibre
Aim for variety rather than relying on one high-fibre food. Easy options include fruit and vegetables, wholegrain or wholemeal bread, oats, canned beans, chickpeas, lentils, nuts and seeds where appropriate, and potatoes or sweet potatoes. Small changes can make a big difference — try a four-bean mix instead of one type of bean, or add half a cup of brown lentils to mince dishes such as spaghetti bolognese or chilli. Remember, increasing fibre without enough fluid can make constipation worse, so increase fibre gradually and increase fluids alongside it.
3. Movement
Movement stimulates the gut. For someone who is independently mobile, a gentle walk after meals can support digestion and may reduce bloating. For someone with significant physical disability, movement may look different. Supported standing, transfers or other appropriate physical activity may still be beneficial.
Can two kiwifruit a day help?
Yes. Kiwifruit provides fibre and contains actinidin, an enzyme that assists protein digestion and may support bowel regularity. Two kiwifruit per day can be a simple strategy to try, with the skin providing additional fibre where safe and appropriate. For someone with dysphagia or a modified-texture diet, don’t simply add whole kiwifruit or other high-fibre foods without checking their swallowing recommendations.
What if constipation continues?
If constipation persists despite adequate fluid, fibre and appropriate movement, don’t just keep adding more fibre. A dietitian can work with the person’s GP to investigate contributing factors such as medications, mobility, swallowing and texture requirements, food intake and toileting routines. A simple bowel diary tracking frequency, stool consistency, straining and symptoms can also provide valuable information.
The bottom line
Good bowel health supports independence, comfort and dignity. Start with the foundations: fluid, varied fibre, appropriate movement and routine. If constipation continues, involve the person’s GP and dietitian to develop a bowel management plan that is safe, practical and realistic for everyday life.
How to get started
If bowel management is an ongoing issue for someone you support, our dietitians can help build a plan that works in their everyday routine. If you are weighing up a referral, these are the signs an NDIS participant should see a dietitian.
Dietetic support is generally funded through the NDIS under Capacity Building — Improved Daily Living or Improved Health and Wellbeing, and in some cases under Core supports. We support self-managed, plan-managed and NDIA-managed participants, our pricing follows the NDIS Price Guide so there is no gap fee, and no doctor’s referral is needed. You can see our fees and how funding works in full.
We offer home visits across Greater Melbourne and parts of regional Victoria, clinic appointments in Dandenong, and telehealth anywhere in Australia. There is no waitlist — we respond to referrals within one business day.
