Imagine this: You stand up to get a glass of water, and suddenly your heart races like you’re running a marathon due to various sensory triggers . Your vision blurs, your head spins, and all you can think about is how to get back to the couch before you faint.
Now imagine layering that physical struggle on top of the sensory overload, social masking, and emotional exhaustion of autism. That’s what life feels like for many autistic people who also live with Postural Orthostatic Tachycardia Syndrome (POTS).
Many people with both conditions experience overlapping symptoms, such as fatigue, sensory processing sensory overload, and dizziness, which can make it difficult to distinguish where one condition ends and the other begins.
It’s a reality that isn’t talked about enough—and yet it impacts daily life, relationships, mental health and self-trust in profound ways.
In this blog post, we’ll explore the hidden link between POTS and autism, what it feels like to live with both, and how you can create a life of greater clarity, connection, and care when your body and brain feel out of sync.
Key Takeaways
- POTS and autism often overlap, leaving people feeling misunderstood and dismissed by the medical system.
- Living with both can amplify fatigue, sensory overwhelm, and relationship challenges, especially those experienced by autistic adults with POTS.
- Healing requires compassion, pacing, and building environments where both your nervous system and cardiovascular system feel safe.
What Is Postural Orthostatic Tachycardia Syndrome (POTS)?
Postural Orthostatic Tachycardia Syndrome (POTS) is a condition that affects the autonomic nervous system—the part of your body that’s supposed to manage things automatically, like heart rate, blood pressure, and blood volume. Symptoms are often triggered by moving to a standing position. POTS is diagnosed using tests that evaluate heart rate and blood pressure when moving from lying down to standing.
In POTS, when you stand up, your heart rate skyrockets. Symptoms may include:
- Dizziness or fainting
- Rapid heartbeat
- Heart palpitations
- Brain fog
- Fatigue
- Nausea
- Feeling shaky or weak
Dizziness and lightheadedness are hallmark symptoms of POTS, which can be particularly distressing for autistic individuals during sensory overwhelm.
Normally, when you move to a standing position, your blood vessels constrict to help maintain blood flow to the brain. In POTS, this process is disrupted, so blood vessels do not constrict properly, leading to symptoms like orthostatic intolerance. A tilt table test helps diagnose autonomic disorders by monitoring heart rate and blood pressure changes when the body is tilted to an upright position.
Doctors often miss it or dismiss it, especially in women and neurodivergent adults with autonomic disorders . Many people go years being told it’s “just anxiety” before finally receiving a diagnosis.
Understanding Autonomic Dysfunction and Its Impact
Autonomic dysfunction happens when your autonomic nervous system—your body’s amazing automatic control center—doesn’t work quite as it should! This incredible system is responsible for regulating those essential functions like your heart rate, blood pressure, and digestion, all without you having to think about it. For you as someone with autism spectrum disorder, autonomic dysfunction can really show up as postural orthostatic tachycardia syndrome (POTS), where standing up triggers a rapid increase in your heart rate and creates a cascade of physical symptoms that can feel overwhelming.
When your autonomic nervous system is out of balance, I know that daily life can feel like a constant battle – and that’s completely understandable! Simple activities that others might take for granted, like getting out of bed or walking across a room, may lead you to experience dizziness, palpitations, and that overwhelming fatigue that just feels so heavy. These physical symptoms often pile right on top of the sensory overload that’s already common in your autism experience, making it even harder for you to cope with everyday demands – and you’re absolutely not alone in this! Using energy management strategies like “Spoon Theory” can help individuals with both autism and POTS to visualize and conserve their energy. Understanding how autonomic dysfunction works is really key to developing treatment strategies that address both your nervous system and your unique needs as an autistic individual. With the right support that truly gets you, it’s absolutely possible to reduce the impact of these symptoms and help you reclaim that sense of stability in your daily life!
The Overlap Between POTS and Autism Spectrum Disorder
Here’s what’s fascinating: research suggests a significant overlap between autism and autonomic nervous system dysfunction such as dysautonomia (autonomic conditions like POTS). Recent studies have found a significant correlation between POTS and autism, highlighting the importance of recognizing this comorbidity. A study showed that about one-third of autistic adults assessed were diagnosed with POTS, emphasizing the need for awareness and tailored care.
Both involve differences in the nervous system. For autistic individuals, that often looks like sensory sensitivity and emotional regulation challenges. For people with POTS, it looks like difficulty regulating blood flow and heart rate. Together, the systems amplify each other.
Many autistic adults describe POTS symptoms being misunderstood as autistic “meltdowns,” anxiety attacks, or laziness. The reality is: it’s your body asking for regulation, not your willpower failing. There is a strong association between autonomic conditions and autism in the research literature, which may help explain these overlapping symptoms. Over 80% of individuals with autism spectrum disorder referred to specialist clinics have a diagnosed autonomic condition, further underscoring this connection. Common POTS symptoms like anxiety-like sensations and gastrointestinal problems can be misinterpreted in autistic individuals, leading to misdiagnosis or delays in treatment.
Comorbid Conditions and Their Effects
For many of you living with autism, dealing with POTS is just one piece of a much larger, more complex picture that you’re navigating every single day! Conditions that often show up together—like chronic fatigue syndrome, irritable bowel syndrome, and autoimmune disorders—are so much more common when you’re on the autism spectrum than in the general population. These overlapping challenges can really intensify what you’re already experiencing with your physical and mental health, often leading to deeper fatigue, ongoing digestive struggles, and those heightened sensory sensitivities that can feel overwhelming!
When you’re managing chronic fatigue syndrome or irritable bowel syndrome alongside POTS, those symptoms like brain fog, sensory processing differences, and autonomic nervous system challenges can become even more intense and real for you! This can make it so much harder to keep up with your daily routines, maintain steady energy levels, and participate fully in the life you want to live. Recognizing these conditions that show up together is absolutely essential for getting the comprehensive, caring support you deserve—addressing not just your nervous system, but also your digestive health, immune system, and mental well-being too! By taking this whole-person approach that really sees you, including your sensory sensitivities you and your care team can create gentle, steady support for both your physical and emotional health in ways that truly honor your unique experience.
A Day in the Life: Living with POTS and Autism
Let’s meet Sam (a composite story).
Sam is a 29-year-old autistic man with POTS. Every morning, he plans his day around his energy levels, navigating executive functioning challenges that make organizing and prioritizing tasks more difficult. Standing too long in the shower can make him dizzy. Driving to work is exhausting because bright lights and traffic noises—overwhelming sensory inputs—flood his sensory system while his body already struggles with circulation.
At the office, he masks his autistic traits to appear “professional.” But POTS adds another layer—he can’t explain why he needs to sit down during standing meetings, or why he sometimes has to put his head between his knees.
By the time he gets home, Sam’s heart and brain feel fried. His partner wants to talk about the day, but he can barely form sentences. Not because he doesn’t care—because his body is running survival protocols.
Sam once said: “It feels like my brain is buffering and my body is lagging, all at once.”
Why POTS and the Autonomic Nervous System Hit Autistic People Harder
Autistic nervous systems already live closer to the edge of overwhelm. Add in dysautonomia, and the body is constantly in a push-pull between regulation and collapse. Executive functioning challenges, such as difficulties with planning and organizing, can make coping with both conditions even more difficult.
- Sensory overload + racing heart: Bright lights or loud sounds hit harder when your body is already in fight-or-flight from POTS.
- Masking + fatigue: Pretending to be fine uses up energy reserves you don’t have, and masking can further worsen fatigue.
- Relationships + invisibility: Partners may misinterpret symptoms as disinterest, rather than survival.
Support strategies are essential to help manage the combined challenges of POTS and autism, as there is no one-size-fits-all solution but several approaches can be effective.
The Burnout Spiral
Many autistic adults with POTS experience a unique form of autistic burnout:
- Physical crashes from standing too long or pushing past limits.
- Cognitive shutdowns from brain fog.
- Emotional withdrawal because explaining feels impossible.
- Chronic pain as a persistent symptom or consequence of burnout.
There is an increased incidence of both autistic burnout and chronic pain in autistic adults with POTS.
The burnout isn’t laziness—it’s your body forcing a shutdown to protect you.
What Helps: Building Safety with POTS and Autism
1. Honor Your Body’s Signals
If you feel dizzy or notice other physical sensations, sit or lie down without apology. Your body isn’t betraying you—it’s communicating clearly.
2. Use External Supports
Compression socks, electrolyte drinks, and mobility aids aren’t signs of weakness. They’re support strategies for managing symptoms and tools of self-respect. Compression garments, like compression socks, can reduce the severity of POTS symptoms by promoting blood circulation, offering a practical way to manage daily challenges.
3. Create Pacing Rituals
Build in “reset breaks” where you lay down, breathe deeply, or reduce sensory input to help prevent actions that could worsen fatigue. Think of them as mini-reboots for your nervous system. Using a pacing system can also help autistic individuals manage energy expenditure and reduce fatigue associated with POTS, creating a more sustainable approach to daily activities. Weighted items can provide calming benefits for autistic individuals experiencing POTS flare-ups.
4. Talk Openly in Relationships
Partners, especially those in close relationships, often feel shut out. Sharing that your fatigue or withdrawal is about POTS, not rejection, creates connection instead of confusion.
5. Seek Practitioners Who Get It
Not every doctor understands autism or POTS. Keep advocating until you find one who treats your lived experience with respect and has experience recognizing and managing a diagnosed autonomic condition.
Nutrition and POTS
Managing your POTS journey often starts with what’s on your plate, and I want you to know that nutrition really can play such a meaningful role in supporting your symptoms and overall well-being! Many people with POTS experience gastrointestinal challenges, so it’s really important to choose foods that feel gentle on your digestive system and can help improve circulation, are easy for your body to absorb. Increasing your salt intake, always under the caring guidance of your medical team, can genuinely help improve your circulation and maintain that vital blood volume your body needs to manage POTS symptoms! Staying well-hydrated is equally important for you, because dehydration can quickly make your symptoms feel so much more challenging when you’re standing or moving around. Drinking plenty of fluids throughout the day can help improve POTS symptoms for autistic individuals, making hydration a key part of symptom management. Making drinking water more enticing can help individuals with POTS increase their fluid intake.
I’ve found that avoiding foods and drinks that trigger your unique symptoms—things like caffeine, alcohol, or highly processed foods—can make such a noticeable difference in how you feel! Since your body is beautifully unique, working with a healthcare professional who really gets you to develop a personalized nutrition plan can be so empowering for managing your POTS and any other conditions you’re navigating. With the right dietary strategies that honor your individual needs, it’s absolutely possible to support your body in amazing ways and improve your daily functioning in meaningful, sustainable ways!
Medical Treatment for POTS
Finding the right approach to treating POTS is never about forcing you into a standard mold – it’s all about discovering what truly works for your unique body and needs! Your treatment journey will likely combine gentle lifestyle shifts with medications that are carefully chosen just for you. Medications like beta blockers, fludrocortisone, or midodrine might be part of your support plan to help your heart rate and blood pressure feel more steady and manageable, but what matters most is finding the approach that honors your individual medical story and family background. A tilt table test is often used to confirm your POTS diagnosis and help guide the treatment choices that will serve you best.
I want you to know that POTS can show up differently for each person – and this is especially true for those of you with autism spectrum disorder, which brings its own amazing strengths and considerations! It’s so important that you work with a healthcare provider who truly gets both autonomic disorders and the beautiful complexity of neurodiversity. Together, you can explore treatment strategies that genuinely address your specific symptoms, support your quality of life, and help you navigate those rapid changes in heart rate and blood pressure that come with POTS. With the right support and understanding, you absolutely can find a treatment plan that feels right and works beautifully for you.

Frequently Asked Questions
What is the link between POTS and autism?
Research suggests shared nervous system differences. Both autism and POTS involve autonomic nervous system dysfunction, and the National Institute for Health and Care Excellence (NICE) recognizes the overlap between these conditions. Autistic individuals have a significantly higher prevalence of POTS and related conditions compared to non autistic individuals. Hypermobility syndromes, such as Ehlers Danlos Syndrome and hypermobile Ehlers Danlos Syndrome, are also more common in this population. Family history can be an important risk factor. Many autistic adults also have dysautonomia, but it is often underdiagnosed.
How do I know if I might have POTS?
Common signs include dizziness, rapid heartbeat, and fatigue when standing. The most common form of POTS involves symptoms triggered by the standing position. Joint hypermobility and gastrointestinal problems are also common in people with POTS, and digestive issues or gut issues may be present. Mast cell activation syndrome and immune dysregulation can contribute to symptoms. Traumatic brain injury can be a risk factor for developing POTS. Certain groups, such as those with a family history or comorbid conditions, are at higher risk. If you notice these patterns, a cardiologist or neurologist can evaluate with a tilt-table test.
Is POTS just anxiety?
No. While symptoms may mimic anxiety, POTS is a physical condition involving blood flow, heart rate regulation, and measurable blood pressure changes. It is a diagnosed autonomic condition, identified through clinical assessment and formal testing, not just a manifestation of anxiety.
How can couples navigate POTS and autism?
By naming the invisible load, pacing together, and building rituals of connection that don’t depend on constant energy or activity while considering sensory processing differences . Couples can also benefit from support strategies tailored to their unique needs, helping them manage the challenges of POTS and autism more effectively.
