When your autonomic nervous system, the part of your nervous system that controls involuntary functions like heart rate, digestion, and blood pressure. Also known as dysautonomia, it works behind the scenes to keep you running—until it doesn’t. Autonomic dysfunction isn’t just feeling tired or dizzy. It’s your body’s internal control panel going haywire. You might stand up and feel like the room is spinning, your heart races for no reason, or you get nauseous just from walking to the fridge. These aren’t "in your head"—they’re physical, measurable, and real.
This condition shows up in many forms. POTS, a type of autonomic dysfunction where standing causes a rapid heart rate increase is one of the most common. Others include orthostatic intolerance, the inability to stay upright without symptoms like lightheadedness or fainting, or neurogenic bowel and bladder issues. People with long COVID, Ehlers-Danlos syndrome, or diabetes often develop it. But it can also happen without a clear cause. The link between stress, inflammation, and nerve damage is growing stronger in research—and many patients report symptoms worsening after infections or trauma.
What’s frustrating isn’t just the symptoms—it’s how often doctors miss it. Blood pressure drops? "It’s anxiety." Heart races? "You’re just stressed." But if you’ve tried everything and nothing helps, it might be your autonomic system. The good news? Management is possible. It’s not about a magic pill, but small, consistent changes: increasing salt and water intake, wearing compression socks, pacing your activity, and sometimes using medications like midodrine or fludrocortisone. Some people find relief with physical therapy designed for autonomic issues. Others benefit from adjusting their diet or timing their meds around daily rhythms.
The posts below aren’t theory—they’re real experiences and practical guides from people who’ve been there. You’ll find comparisons of medications used to manage symptoms, tips on dealing with daily triggers like heat or standing too long, and stories from others who learned how to live with this invisible condition. Whether you’re newly diagnosed or have been fighting this for years, there’s something here that speaks to your reality.
