People with autism do feel hunger and thirst, but they may have significant difficulty recognizing and interpreting these internal body signals due to a common challenge called interoception differences.
Some autistic people don't feel hungry or alternatively never feel full. This is all to do with Interoception, the senses inside us that monitor hunger, thirst and when we need to go to the toilet. They may need to be prompted to eat or be helped to control their portions.
Autistic individuals often experience and express love and connection in ways that can differ from neurotypical expectations. Communication for autistic people in relationships tends to be direct and literal; understanding nonverbal cues can sometimes be a challenge.
For example, a toddler learning a second language might have speech delays that look like a red flag. Or a child with sensory processing challenges might avoid certain sounds or textures, which can mimic autistic traits. However, these signs alone don't confirm autism.
Main signs of autism
Common signs of autism in adults include: finding it hard to understand what others are thinking or feeling. getting very anxious about social situations. finding it hard to make friends or preferring to be on your own.
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.
Seven key signs of autism spectrum disorder (ASD) often involve challenges with social communication (like avoiding eye contact, not responding to names), restricted/repetitive behaviors (like repetitive movements or strict routines), sensory sensitivities (unusual reactions to sounds, lights, textures), and difficulties with emotional understanding or verbal expression, though signs vary greatly and appear differently across ages. Key indicators include limited gestures, delayed speech, intense focus on specific objects, difficulty with pretend play, and strong distress when routines change.
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.
Conditions That Can Be Mistaken for Autism. These include: Speech delays, hearing problems, or other developmental delays: Developmental delays are when your child doesn't do things doctors expect kids their age to be able to do. These can include language, speech, or hearing problems.
"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.
Rather than using traditional flirting techniques like playful banter or subtle body language, autistic individuals might express interest by: Initiating in-depth conversations about shared interests. Being exceptionally reliable and consistent in their interactions.
Heightened sensitivities to touch, light, sound or other sensory inputs can easily create friction points in relationships. Sensory processing issues can lead to discomfort, distress and even overload during physically intimate moments.
What NOT to Say to Someone with Autism
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.
The three main symptom areas for Autism Spectrum Disorder (ASD) are persistent difficulties with social communication and interaction, restricted or repetitive patterns of behavior, interests, or activities, and often, different ways of learning, moving, or paying attention, all of which impact daily functioning. These core characteristics vary greatly but center on social connection challenges, rigid routines or repetitive actions, and sensory sensitivities.
Yelling at an autistic child can cause confusion, fear, and emotional distress that may last far longer than you'd expect. Because autistic kids often process language, tone, and emotions differently, loud voices can be overwhelming—sometimes even physically painful.
Here are five common false signs of autism that are often misunderstood.
Mental health problems
Many autistic people have problems like: feeling very worried a lot of the time (anxiety) feeling unhappy, irritable or hopeless (depression) feeling a need to keep doing certain actions (obsessive compulsive disorder, or OCD)
For the uninitiated, PANDAS is an acronym for pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections. These disorders involve the sudden onset of obsessive-compulsive disorder (OCD) or tics in children following a strep infection such as strep throat or scarlet fever.
Children with autism may exhibit rigidity, inflexibility and certain types of repetitive behavior such as: Insistence on following a specific routine. Having difficulty accepting changes in the schedule. A strong preoccupation with a particular interest.
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.
Floortime does not work on speech, motor or cognitive skills in isolation. It addresses these areas through its focus on emotional development. Overall, this method encourages children with autism to push themselves to their full potential. It develops “who they are,” rather than “what their diagnosis says.”

Genetics. Several genes seem to be involved in autism spectrum disorder. For some children, autism spectrum disorder can be related to a genetic condition, such as Rett syndrome or fragile X syndrome. For other children, genetic changes, also known as mutations, may raise the risk of autism spectrum disorder.
