What Does Autism Do to Your Body?

Understanding Autism

Autism is a complex disorder that affects people differently. Some individuals with autism spectrum disorder (ASD) struggle with social interactions and communication, while others have repetitive behaviors and intense interests. The symptoms of autism can vary widely, and it can be difficult to diagnose.

Research shows that autism is caused by a combination of genetic and environmental factors, though the exact cause is still unknown. Studies have suggested that certain genes may increase the risk of developing autism, but no single gene has been identified as the cause. Environmental factors such as prenatal exposure to toxins or infections are also thought to play a role.

Abnormalities in brain development are believed to play a significant role in autism. Research has shown that individuals with autism have differences in the structure and function of certain areas of the brain. These differences can affect how individuals with autism process sensory information, interact with others, and communicate.

There is currently no cure for autism, but early intervention and therapy can help individuals with autism develop important skills and improve their quality of life. If you or someone you know is struggling with autism, there are many resources available to provide support and guidance.

Physical Effects of Autism

While autism is primarily a disorder of the brain, it can also have physical effects on the body. Here are some of the most common physical effects associated with autism:

Digestive Issues

Digestive issues are a common problem for many people with autism. These issues can include constipation, diarrhea, and bloating. One possible cause of these issues is a sensitivity to certain foods.

Another possible cause is a lack of diversity in the gut microbiome. This is the collection of microorganisms that live in the digestive tract and help with digestion. When the gut microbiome is not diverse enough, it can lead to digestive problems.

Sleep Issues

Sleep problems are a major concern for people with autism. Many individuals with autism struggle with falling asleep, staying asleep, or waking up early. These sleep disturbances can lead to fatigue and other health problems. It is important to address sleep issues in people with autism in order to improve their overall health and well-being.

Sensory Issues

Sensory issues are a common problem for many people with autism. Individuals with autism may be hypersensitive or hyposensitive to sensory stimuli, such as touch, sound, and light. This can lead to discomfort, pain, and other physical symptoms. It is important to understand and address sensory issues in people with autism in order to improve their quality of life.

Motor Coordination Issues

Motor coordination issues are a challenge for some people with autism. These issues can affect an individual's ability to perform certain physical activities. People with autism may struggle with coordination and balance, which can make it difficult to participate in sports or other physical activities. It is important to work with individuals with autism to develop strategies to improve their motor coordination.


Epilepsy is a neurological disorder that is more common in people with autism than in the general population. Epilepsy is characterized by seizures, which can be frightening and dangerous. It is important to work with individuals with autism who have epilepsy to develop a treatment plan that can help to manage their seizures and improve their quality of life.

Early Diagnosis and Intervention for Autism

Early diagnosis and intervention are crucial for individuals with autism. The earlier a child is diagnosed with autism, the earlier they can receive the support and therapy they need to improve their quality of life. Early intervention can help children with autism develop important skills such as communication, social interaction, and coping mechanisms.

Studies have shown that early intervention can lead to significant improvements in language development, cognitive abilities, and adaptive behavior. Children who receive early intervention are more likely to make progress in their development and have better long-term outcomes.

It is important for parents and caregivers to be aware of the signs of autism so that they can seek an evaluation if they suspect their child may have the disorder. Some signs of autism include delayed speech or language skills, difficulty making eye contact or engaging in social interactions, repetitive behaviors or routines, and sensory sensitivities.

If you suspect your child may have autism, it is important to talk to your pediatrician or a healthcare professional who specializes in developmental disorders. They can provide a referral for an evaluation and connect you with resources to help you navigate the process.

Impact on Family Dynamics and Relationships

Autism can have a significant impact on family dynamics and relationships. Caring for a child or family member with autism can be challenging and stressful, which can lead to tension and conflict within the family.

Parents of children with autism may experience higher levels of stress, anxiety, and depression than parents of typically developing children. They may also struggle to balance the needs of their child with autism with the needs of their other children or family members.

Siblings of children with autism may also experience unique challenges. They may feel neglected or overlooked by their parents, who are focused on caring for their sibling with autism. Siblings may also feel embarrassed or frustrated by their sibling's behavior in public settings.

Extended family members and friends may also struggle to understand and support families affected by autism. They may not know how to interact with a child with autism or how to provide meaningful support to the family.

It is important for families affected by autism to seek support and resources to help them navigate these challenges. Support groups, therapy, and respite care can all be helpful in reducing stress and improving family relationships.

It is also important for families to educate themselves about autism so that they can better understand their loved one's needs and behaviors. With support and understanding, families affected by autism can thrive together.

Challenges Faced by Adults with Autism

Autism can continue to pose challenges for individuals as they grow older, particularly in the workplace and community settings. Many adults with autism struggle with finding and maintaining employment due to communication difficulties, sensory sensitivities, and social skills deficits. These challenges can make it difficult for individuals with autism to navigate the expectations of employers and colleagues.

In addition to the challenges in the workplace, adults with autism may also face difficulties in their communities. They may struggle with social interactions or feel isolated from others who do not understand their condition. This can lead to feelings of loneliness and depression.

It is important for employers and community members to be educated about autism and its effects on individuals. Educating others can help reduce stigma around the disorder and create more supportive environments for people with autism.

There are also resources available that can help individuals with autism navigate these challenges. Vocational training programs, job coaches, and support groups can all provide valuable assistance to adults with autism as they work towards greater independence and success in their careers and communities.

Types of Therapy for Autism

There are various types of therapy available for people with autism. Here are some examples:

Applied Behavior Analysis (ABA)

Applied Behavior Analysis (ABA) is a type of therapy that focuses on teaching positive behaviors and reducing negative behaviors. ABA therapy is often used to teach social skills, communication, and self-care skills. It can be tailored to meet the specific needs of each individual with autism.

Speech Therapy

Speech therapy can help individuals with autism improve their communication skills. This type of therapy can focus on developing language skills, improving articulation, and enhancing social communication.

Occupational Therapy

Occupational therapy can help individuals with autism develop important life skills such as dressing themselves, brushing their teeth, and preparing meals. Occupational therapists work to improve fine motor skills, coordination, and sensory processing.

Sensory Integration Therapy

Sensory integration therapy can help individuals with autism better process sensory information. This type of therapy involves activities that stimulate the senses in a structured and repetitive way. The goal is to help individuals with autism become more comfortable with sensory experiences.

It is important for families affected by autism to work with healthcare professionals to determine which types of therapy may be most beneficial for their loved one. With the right support and resources, individuals with autism can lead fulfilling lives and reach their full potential.

Supporting Individuals with Autism in Daily Life

Individuals with autism often require support to navigate their daily lives. Here are some strategies that can help support individuals with autism:

Establishing Routines

Establishing routines can be helpful for individuals with autism as it provides structure and predictability. Routines can include daily schedules for meals, activities, and bedtime. It is important to communicate these routines clearly and consistently.

Using Visual Aids

Visual aids such as picture schedules or social stories can also be helpful for individuals with autism. These tools provide visual cues that can aid in communication and understanding.

Providing Sensory Support

Individuals with autism may have sensory sensitivities that can make certain environments overwhelming or uncomfortable. Providing sensory support such as noise-cancelling headphones or a weighted blanket can help individuals with autism regulate their sensory experiences.

Encouraging Communication

Encouraging communication is important for individuals with autism who may struggle to express themselves verbally. This could involve using alternative forms of communication such as sign language or assistive technology.

Emphasizing Strengths

It is important to recognize and emphasize the strengths of individuals with autism. This could include interests or talents that the individual has, which could be incorporated into daily activities or hobbies.

By implementing these strategies, we can better support individuals with autism in their daily lives and help them reach their full potential.

Strategies for managing sensory overload in people with autism

Sensory overload is a common problem for individuals with autism. Here are some strategies that can help manage sensory overload:

Identify Triggers

Identifying triggers can be helpful in preventing sensory overload. Common triggers include loud noises, bright lights, and certain textures or smells. By identifying these triggers, individuals with autism can take steps to avoid them or prepare themselves when they cannot be avoided.

Create a Safe Space

Creating a safe space at home or in the classroom can also be helpful for managing sensory overload. This could be a quiet room or corner where the individual can go to relax and decompress. The safe space should be free of any triggers and have calming elements such as soft lighting and comfortable seating.

Use Sensory Tools

Sensory tools such as fidget toys, weighted blankets, and noise-cancelling headphones can also be helpful in managing sensory overload. These tools provide individuals with autism with an outlet for their sensory experiences and can help regulate their emotions.

Practice Deep Breathing Techniques

Deep breathing techniques such as diaphragmatic breathing or box breathing can help individuals with autism manage their stress levels and reduce anxiety. Encouraging deep breathing during times of stress or sensory overload can help calm the nervous system.

By implementing these strategies, we can better support individuals with autism in managing their sensory experiences and improving their quality of life.


Can autism cause immune system problems?

Recent studies suggest that there may be a link between autism and immune system dysfunction. Some people with autism have been found to have abnormal levels of certain immune cells, which can lead to inflammation and other health problems.

Does autism affect the cardiovascular system?

While research on the link between autism and cardiovascular health is still limited, some studies have suggested that people with autism may be at higher risk for certain cardiovascular conditions, such as hypertension and heart disease.

Can physical therapy help with motor coordination issues in people with autism?

Physical therapy can be an effective way to improve motor coordination in people with autism. Through exercises and activities designed to improve balance, strength, and coordination, physical therapy can help individuals with autism learn to perform physical tasks more easily and confidently.
