Autonomic / Vasovagal Episode
Last night I experienced one of the most frightening physical episodes I’ve ever had.
It began with sudden dizziness and a strong sensation that I might pass out. Almost immediately afterward, my body broke into intense cold sweats not mild clamminess, but full-on dripping sweat. Severe nausea followed, along with a powerful, uncontrollable urge to use the bathroom.
What made it so terrifying was the overlap: vomiting and bowel urgency happening together, repeatedly. I was too dizzy to stand comfortably and too nauseous to sit still. My body felt completely hijacked no position was tolerable.
This cycle went on for roughly an hour. Eventually, the symptoms eased just enough for me to make it back to bed, though vomiting returned briefly afterward. At that point, exhaustion took over and I slept for a few hours.
When I woke, I still felt weak and dizzy but was stable enough to check my vitals:
- Blood sugar: 145 (elevated but not dangerous, and not low)
- Blood pressure: elevated systolic, normal diastolic
- Heart rate: normal and steady
Based on symptom pattern and recovery, the most likely explanation is an autonomic (vasovagal) episode a sudden misfire of the autonomic nervous system. This system controls involuntary functions like blood pressure, digestion, sweating, and heart rate.
The episode likely involved:
- A rapid drop in blood pressure → dizziness and nausea
- Followed by an adrenaline surge → sweating, shakiness, weakness
- Intense vagus nerve activation → vomiting and bowel urgency
Importantly, my heart rhythm remained normal, and symptoms fully resolved with rest, hydration, and time.
Today was spent recovering: limited meds initially, slow hydration, bland food, and rest. Even after improvement, there was a lingering “off” feeling consistent with nervous system recovery after a strong autonomic event.
This was frightening, disorienting, and exhausting but not a heart attack, stroke, or infection. Follow-up with my doctor is necessary, but for now, the body appears to be stabilizing.
A reminder that the body can create extreme sensations without structural damage and that listening, stopping, and resting matters.
