Converge 2026: Connecting the Autonomic dots

Understanding Your Body’s Interconnected Sensitive Systems

• Author's Disclaimer

  The following series translations reframe the clinical data from the Australian POTS Foundation Converge 2026 conference through a neuroaffirming, trauma-informed lens. As a psychologist, I do not provide medical advice or prescribe treatments; instead, my goal is to help you bridge the gap between complex physiological findings, somatic regulation practices, and systemic well-being.

If you live with Postural Orthostatic Tachycardia Syndrome (POTS), hypermobile Ehlers-Danlos Syndrome (hEDS), or Mast Cell Activation Syndrome (MCAS), your daily experience with digestion can feel incredibly unpredictable. It is common to feel like your body is constantly throwing random curveballs at you. One of the most validating takeaways from the general medicine sessions at the Converge 2026 conference is that these symptoms are not in your head, nor are they a series of separate, disconnected faults. Instead, they represent a highly sensitive, deeply interconnected triad of systems that talk to each other constantly.

When we translate the science into a supportive framework, we see three distinct themes:

• The Structural Picture (hEDS/HSD): Collagen is the foundational scaffolding of our entire digestive tract. When your body naturally produces a softer, more flexible type of collagen, the physical walls of the gut have less structural stiffness. This natural tissue laxity makes it physically harder for the body to move food along smoothly, which can show up as intense bloating, feeling full quickly, or changes in how your gut moves.

• The Communication Link (POTS): The gut has its own intricate network of nerves, often called the "second brain," which balances blood flow and digestion. In a highly responsive autonomic nervous system, blood can pool in the abdomen, meaning your body has to work much harder to keep everything balanced, especially after eating.

• The Protective Immune Response (MCAS): Mast cells are our body's brilliant front-line defenders. However, when they are hyper-reactive, they release chemical signals like histamine that create localised irritation, heighten your body’s internal sensitivity to pain, and alter how food is tolerated.

The Somatic Connection

From a somatic regulation perspective, we view the gut as a sensitive mirror of your nervous system's overall equilibrium. Because standard structural testing (like standard endoscopies or routine scans) often looks for obvious physical damage, your results might come back completely normal, even when you are experiencing profound discomfort. This does not mean your symptoms are not real; it simply means the tests are looking at the structure rather than the function.

When your gut is working beautifully with a highly sensitive nervous system, practicing gentle, non-judgmental tracking can help you learn your body's personal language. Rather than fighting the symptom, we can use somatic tools - like calming down a post-meal adrenaline rush with slow, extended exhales - to signal safety to both the brain and the belly.

Where to Find More Information:

To explore this interconnected triad further, look into the following resources:

• The clinical reviews detailing these structural and immune overlaps can be explored in the peer-reviewed findings of the landmark AGA Expert Review (2025) and the global Rome IV DGBI Study.

• For excellent patient-centered education on connective tissue health and dysautonomia, explore the comprehensive toolkits hosted by The Ehlers-Danlos Society and Dysautonomia International.
