16 Apr Is My Autistic Child Going To Be Sicker Than Other Children?
When families first receive an autism diagnosis, one of the quiet worries that often follows is this: Is my child going to be sicker than other children?
From my professional experience, working with hundreds of young autistic children, the answer is not as straightforward as many expect—but it is often more reassuring than feared. Autism itself does not make a child inherently “more sickly” than their neurotypical peers.
In fact, I have often observed the opposite. Neurotypical children, by nature, tend to be more socially interactive—sharing toys, food, close contact, and play—which naturally increases their exposure to everyday illnesses like colds and flu.
Many autistic children, due to differences in social communication and interaction, may actually have fewer of these exposures. In some ways, this can act as a quiet protective factor during common seasonal illnesses.
That said, certain health patterns do appear more frequently in children on the autism spectrum, and parents need to be aware of them without becoming overwhelmed. One of the more widely recognized co-occurring conditions is epilepsy.
Research suggests that a notable percentage of autistic individuals—often estimated between 20% and 30%—may experience seizures at some point in their lives. These can present at different stages, but many families begin to notice signs during later childhood or adolescence. While this may sound alarming, many children are successfully managed with the right medical support, and early awareness enables quicker intervention and peace of mind.
Sleep challenges or disorders, however, is often the area that most families feel the impact of immediately and consistently. It is estimated that up to 70–80% of children with autism experience some form of sleep disturbance.
This is not just about a child who “doesn’t sleep well”—it can look like difficulty falling asleep, frequent nighttime waking, or very early rising. Over time, this affects not only the child’s behavior, concentration, and emotional regulation but also the entire family’s well-being.
A tired child may struggle more with transitions, communication, and daily demands, and parents often find themselves equally exhausted. Understanding that sleep challenges are part of the profile for many autistic children helps shift the mindset from frustration to problem-solving and support.
Another area that frequently comes up in both classrooms and homes is gastrointestinal health. Many children with autism experience ongoing “tummy troubles”—ranging from constipation to very loose stools, discomfort, or difficulty with toileting routines. These challenges can affect behavior, appetite, and overall comfort in ways that are not always immediately obvious. Closely linked to this is feeding.
In my experience, feeding difficulties are one of the most common and most misunderstood aspects of autism. Many children are not simply “fussy eaters”—they are navigating a complex sensory world where taste, texture, smell, colour, and even predictability matter deeply.
A crisp or a fast-food chip is often accepted because it is consistent—same taste, same crunch, every time. But a blueberry? It can be sweet or sour, soft or firm, large or small. That inconsistency can feel overwhelming. Over time, this can lead to very restricted diets, nutritional gaps, or behaviours such as food stuffing, gagging, or even pica—where a child eats non-food items like paper, soil, or small objects. Pica is not uncommon and should always be addressed with professional guidance, as it can pose health risks.
When we step back and look at the bigger picture, we begin to see how these elements connect. Feeding challenges may affect nutrition, which in turn can affect a child’s immune system and overall resilience.
Gastrointestinal discomfort can impact sleep, and poor sleep can affect behavior and emotional regulation. Yet even with all of this, it is important to come back to the central message: autistic children are not inherently “sicker” children. They have a different set of needs that require understanding, observation, and thoughtful support.
Where there are concerns around nutrition or supplementation, it is always advisable to work closely with a healthcare professional to ensure that any interventions are safe and appropriate for your child.
For parents at the beginning of this journey, the most important takeaway is this: you are not alone, and these challenges are both recognized and manageable. With the right support, awareness, and a gentle understanding of your child’s unique sensory and developmental profile, you will find your rhythm. And within that rhythm, your child can grow, thrive, and feel well in their own way.
