Yes, autism is strongly linked to metabolic differences, affecting energy use, amino acid processing, folate metabolism, mitochondrial function, gut health, and increasing risks for obesity and related metabolic issues like type 2 diabetes, often due to variations in pathways like purine metabolism and glutathione metabolism, sometimes stemming from underlying genetic factors or co-occurring conditions.
This can be especially difficult for teens with autism, many of whom have less developed motor and coordination skills. It's also true that we all experience a slowing of metabolism as we get older. That means your teen with autism may be burning fewer calories – even at rest – than he did when he was younger.
Symptoms of High-Functioning Autism
Difficulty with Social Interaction: Individuals with high-functioning autism may struggle to understand social norms, make eye contact, initiate or maintain conversations, and interpret nonverbal cues such as facial expressions or body language.
Results. Autistic adults were more likely to be in non-healthy weight categories than their non-autistic counterparts, i.e., more likely to be underweight, overweight, or obese.
Autistic individuals often have a lower life expectancy due to co-occurring conditions like epilepsy, mental health challenges, limited access to quality healthcare, and higher risk of accidents. Social factors like isolation, poverty, and inadequate support also contribute to early mortality.
The longest living autistic person known is Donald Gray Triplett, famously known as “Case 1,” who was the first person ever diagnosed with autism. He lived until 89 years old, passing away in 2023.
Among the causes of death, 27.9% were due to injuries, with suffocation being the most common, followed by asphyxia and drowning. The increased risk of drowning among autistic individuals has been confirmed by two additional studies.
Around 90% of autism cases are attributed to genetic factors, meaning autism is highly heritable, with many different genes contributing, rather than a single cause, often interacting with environmental influences during early brain development, though specific environmental factors don't cause it but can increase risk. Twin studies show strong genetic links, with concordance rates between 60-90% in identical twins, and research points to complex interactions of many genes and prenatal/perinatal factors.
The "6-second rule" for autism is a communication strategy where a speaker pauses for about six seconds after asking a question or giving information, giving the autistic person extra time to process it without feeling rushed, which helps reduce anxiety and allows for a more thoughtful response, reducing frustration for both parties. Instead of repeating or rephrasing, which can be confusing, you wait, and if needed, repeat the exact same words after the pause.
Autism can influence weight in various ways, from selective eating habits to difficulties in establishing new routines. Studies show that autistic individuals are at a higher risk of both obesity and undernutrition due to food aversions, routine-driven eating patterns, and challenges with physical activity.
The different types of autism include autism spectrum disorder (ASD), autistic disorder (classic autism), Asperger's syndrome, pervasive developmental disorder not otherwise specified (PDD-NOS), childhood disintegrative disorder (CDD), and Rett syndrome.
Physical Symptoms:
Mojdeh Mostafavi, MD, describes gastrointestinal conditions commonly seen in individuals with autism, including gastroesophageal reflux disease (GERD), inflammatory bowel disease (IBD), Eosinophilic GI disease (EGID), avoidant/restrictive food intake disorder (ARFID), disorders of.
Chinning is a form of repetitive self-stimulatory behavior (stimming) that you may notice in children or adults with autism. It involves pressing, rubbing, or holding the chin against objects, surfaces, or even hands to gain sensory input or comfort.
Some studies have suggested that there may be a slightly higher prevalence of autism among individuals with RH-negative blood type compared to those with RH-positive blood type. However, it is important to note that these findings are not conclusive, and further research is needed to establish a definitive connection.
"Looping" in autism refers to getting "stuck" in repetitive mental cycles, replaying thoughts, questions, worries, or phrases endlessly, often triggered by stress, sensory overload, or uncertainty, and linked to challenges with executive function and attention. It's a non-clinical term for perseveration or rumination, where an autistic individual's brain struggles to shift focus from an internal loop, which can be mentally exhausting but sometimes also comforting.
There's no single "hardest" age for autism; challenges shift across developmental stages, with preschool (2-5) often tough due to noticeable differences in social/language skills, elementary (6-10) marked by growing academic/social demands, and adolescence (11-17) frequently being overwhelming due to complex social pressures, puberty, and identity formation, say Bluebell ABA Therapy and Blossom ABA Therapy. While early childhood (ages 3-6) sees initial progress for many, this often stalls around age six, a critical turning point where increased support is crucial, according to research, notes The Transmitter.
In general, people who have an active lifestyle are much more emotionally resilient and focused. There also seems to be some evidence that physical exercise helps people with depression and ADHD, which are commonly co-occurring conditions with autism.
Changes in the diagnostic criteria and increased screening at wellness visits seem to be the main contributors.
Additionally, inherited genetic variations contribute greatly. Research shows that both mothers and fathers can carry autism-related gene variants. Some of these are common variants that increase the risk of autism, while others are rare mutations causing more severe effects.
We reviewed 36 studies examining maternal diet and autism spectrum disorder (ASD) and found that prenatal vitamin/multivitamin use and adequate intake of folic acid and vitamin D were each associated with lower likelihood of having a child with ASD.
Savant syndrome is a rare, but extraordinary, condition in which persons with serious mental disabilities, including autistic disorder, have some 'island of genius' which stands in marked, incongruous contrast to overall handicap.
The longest living autistic person known is Donald Gray Triplett, the first person ever diagnosed with autism. He lived to be 89 years old and passed away in 2023.
