Many autistic people notice that they do not only have one difference. Autism often comes alongside other forms of neurodivergence and certain physical conditions. If that is your experience, you are not imagining a pattern. These links are real and increasingly well documented.
Autism and ADHD frequently occur together, so often that many people identify with both. Dyslexia, dyspraxia, dyscalculia, and other differences also commonly overlap. Brains that develop differently in one way often differ in several ways at once, which is why one label rarely captures a whole person.
Autistic people report higher rates of certain physical conditions, including hypermobility and Ehlers Danlos syndromes, chronic pain, fatigue, and digestive issues. Researchers are still mapping exactly why, but connective tissue, the nervous system, and how the body regulates itself all appear to be involved. The mind and body are not separate systems.
Many autistic people also experience interoception differently, meaning the internal signals of hunger, thirst, pain, or needing to rest can be hard to read. This can make health issues easier to miss and harder to describe, which is one reason autistic people are sometimes not taken seriously in medical settings.
Knowing that these conditions cluster together helps autistic people make sense of their experience and seek the right support without feeling like a puzzle no one can solve. If you are autistic and living with chronic pain or fatigue, it is worth finding professionals who understand these connections and will listen to you.
One theory is that the same underlying differences in nervous system development that shape autistic sensory processing and cognition also affect connective tissue and the body’s regulatory systems more broadly. Another is that chronic stress from masking and navigating an unaccommodating world takes a physical toll over years, contributing to fatigue and pain. Both are likely part of the picture, and research is still catching up with what autistic people have been reporting for a long time.
Autistic people with undiagnosed EDS, chronic pain or additional neurodivergence are often told their symptoms are “just anxiety” or dismissed altogether, especially when clinicians aren’t looking for the pattern. Getting the full picture, rather than treating each condition in isolation, leads to much better care and to explanations that finally make sense of years of unexplained struggle.
Should I get assessed for other conditions if I’m autistic?
If you notice patterns like joint hypermobility, chronic fatigue, digestive issues, or traits of ADHD or another neurodivergence, it’s worth raising with a GP or specialist. This isn’t a diagnosis, just a starting point for a conversation.
Does having multiple conditions mean autism was misdiagnosed?
No. Co-occurring conditions are common and don’t change or invalidate an autism diagnosis. They simply mean the full picture needs more than one label to describe it.
Managing autism alongside conditions like ADHD, EDS or chronic pain often means support plans need to address more than one thing at once. A sensory accommodation that helps with autism might also ease pain from hypermobility. A routine that supports autistic regulation might also help manage ADHD-related overwhelm. Looking at the whole picture, rather than treating each diagnosis in isolation, usually leads to more effective support.
