Failure to Thrive: Symptoms, Diagnosis & Treatment
A clear guide to failure to thrive in infants and children, covering warning signs, diagnosis and a plan to support healthy growth.
Treatment usually begins with
Growth Assessment
Nutritional Review
Nutrition Plan
Growth Monitoring
Most cases improve with a structured nutrition and feeding plan tailored to the child.
You may need this evaluated if...
A growth evaluation is recommended when these signs appear:
- Weight gain is slower than expected for age
- Height or weight has dropped across growth chart percentiles
- Feeding difficulties are present
- Your child seems less active or alert than expected
Most children catch up well in growth once the underlying cause is identified and addressed.
What is Failure to Thrive?
Failure to thrive describes a child not gaining weight or growing as expected for their age, often linked to feeding difficulties, an underlying condition or nutritional gaps.
Growth Chart Guided
Tracked using standard growth charts over time.
Several Possible Causes
Feeding difficulties, nutrition or an underlying condition can all contribute.
Assessed Holistically
Diet, feeding pattern and general health are all reviewed.
Responds to a Plan
Most children show good catch-up growth with the right support.
Common Symptoms
- Slower than expected weight gain
- Smaller than average height or weight for age
- Delayed developmental milestones
- Low energy
- Reduced interest in feeding
What Increases the Risk
A combination of medical, developmental and environmental factors can increase the likelihood of this condition.
How It Is Diagnosed
A structured assessment confirms the diagnosis and helps guide the right treatment plan.
1. Growth chart review
Comparing weight and height trends to standard charts.
2. Feeding & nutrition history
Understanding diet and feeding patterns.
3. Further tests, if needed
Blood tests help identify an underlying medical cause.
Treatment Approaches
Medical Care
- Personalised Nutrition Plan
- Feeding Support & Guidance
- Addressing Any Underlying Condition
- Regular Growth Monitoring
Surgical Care
Surgery is not a routine treatment for failure to thrive, unless a specific structural feeding problem is identified.
Treatment decisions are based on the child's symptoms, growth, timing and overall health, not a single test.
Know When to Act
Recognising these signs early and acting promptly is important for the best outcome.
Book an Assessment
Schedule a consultation for a routine evaluation or ongoing symptoms.
- You want a routine growth check for your child
- You want guidance on feeding and nutrition
- You want a follow-up on an existing growth plan
Seek Urgent Care
Call for emergency care immediately if you notice any of the following.
- Weight loss is significant or rapid
- Your child appears unusually lethargic or unresponsive
- Feeding has stopped almost entirely
