Knowing when to involve a dietitian can make a significant difference to an NDIS participant’s health, independence and quality of life. You don’t need to wait until someone has a major nutrition problem — unexplained changes in weight, ongoing gut symptoms, low energy, restrictive eating or difficulty managing meals are all reasons to consider dietetic support.

What are the signs someone may benefit from seeing a dietitian?

1. There has been an unexplained change in weight

Unintentional weight loss or weight gain should not be ignored, regardless of the person’s starting weight or body size. Ongoing weight loss can increase the risk of malnutrition, nutrient deficiencies, reduced muscle strength and poorer recovery from illness. Unexpected weight gain can also affect mobility, comfort and independence. A dietitian can assess what is driving the change and develop an appropriate plan.

2. They have a chronic health condition

Conditions such as type 2 diabetes, heart disease, high blood pressure or autoimmune conditions can all benefit from nutrition support. A dietitian can translate general medical advice into practical meals, snacks and routines that work within the participant’s abilities, preferences and support environment.

3. You suspect a food allergy, intolerance or reaction

If someone consistently experiences symptoms after eating particular foods, it is worth investigating rather than unnecessarily removing foods. A dietitian can help identify patterns, support appropriate medical investigation and ensure that any dietary changes don’t unnecessarily restrict the person’s nutrition.

4. They have started a new medication

Some medications can affect appetite, weight, blood glucose, bowel function or food intake. If you notice a significant change after starting or changing medication, involve the participant’s GP and dietitian. Nutrition strategies can often be adjusted alongside the medication rather than waiting for the problem to become significant.

5. They have had significant surgery

The body requires extra energy, protein and nutrients to heal and recover after surgery. Recovery can be even more complex for people living with disability, particularly when mobility, swallowing, appetite or independence with meals is already affected. A dietitian can help ensure nutrition supports recovery and reduces the risk of malnutrition.

6. They have ongoing digestive or bowel problems

Ongoing stomach pain, cramping, constipation, diarrhoea, bloating or bowel urgency should be investigated. These symptoms can affect appetite, food intake, mood and quality of life. A dietitian can work alongside the GP to identify dietary contributors and develop practical strategies.

7. You notice restrictive or disordered eating

This may look like avoiding entire food groups, extreme food rules, fear around certain foods, significant restriction or distress around eating. These behaviours should be taken seriously. A dietitian can help identify nutrition risks and, where appropriate, work alongside the participant’s GP and mental health team.

8. They have ongoing low energy or fatigue

If someone is consistently tired, has low energy or struggles to participate in their usual activities, nutrition may be one piece of the puzzle. Inadequate energy intake, low protein, iron or other nutrient deficiencies can contribute to fatigue. A dietitian can assess whether the person’s current intake is meeting their needs and work alongside their healthcare team to investigate other causes.

9. Mealtimes are stressful

If meals regularly cause stress, anxiety, arguments, food refusal or frustration for the participant or their support team, you don’t have to simply accept it as “fussy eating”. Persistent refusal of food groups, very limited food variety or difficulty managing meals can increase the risk of inadequate nutrition. A dietitian can help make meals more manageable, enjoyable and nutritionally adequate.

10. Blood tests show low nutrient levels

If blood tests show low levels of nutrients such as iron, B12, folate or vitamin D, a dietitian can help identify whether dietary intake may be contributing and develop strategies to improve nutrition. Supplementation may sometimes be required, but the underlying cause should also be considered with the person’s GP or treating team.

When should you involve a dietitian?

Don’t wait until nutrition problems become severe.

For NDIS participants, nutrition can directly influence energy, strength, mobility, recovery, bowel function, independence and participation in everyday life. If you notice one or more of these signs, a dietitian can help identify what is happening and develop practical strategies that fit the person’s abilities, preferences, routines and support environment. Early nutrition support can help prevent a small problem from becoming a much bigger one.

How to get started

If any of these signs apply to a participant you support, we’re happy to talk it through before you refer.

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, and more on how we work with support coordinators.

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.
