When your body can’t properly adjust your blood pressure, it’s often due to baroreflex failure, a condition where the baroreceptors in your arteries stop sending correct signals to your brain about blood pressure changes. Also known as baroreceptor dysfunction, it leaves you vulnerable to sudden spikes or crashes in blood pressure—sometimes without warning.
This isn’t just about feeling dizzy when you stand up. baroreflex failure disrupts the autonomic nervous system, the part of your body that handles breathing, heart rate, and digestion without you thinking about it. When it fails, your heart doesn’t speed up when you stand, and your blood vessels don’t tighten to keep pressure stable. That’s why people with this condition often experience orthostatic hypotension—a dangerous drop in blood pressure upon standing—and sudden, extreme highs when stressed or active. It’s not anxiety. It’s not dehydration. It’s your body’s internal thermostat breaking.
Baroreflex failure usually happens after damage to the nerves or brainstem—often from surgery, trauma, or rare neurological diseases. Some people develop it after neck surgery or radiation therapy. Others have it without a clear cause. Symptoms include pounding headaches, blurred vision, chest pain, palpitations, and fainting. Many patients are misdiagnosed for years because doctors don’t connect the dots between random episodes of high and low blood pressure. If you’ve been told you have "unexplained hypertension" or "vague dizziness," and nothing seems to help, baroreflex failure might be the missing piece.
There’s no single test to confirm it. Diagnosis relies on monitoring blood pressure and heart rate over time, especially during posture changes or stress tests. Treatment isn’t one-size-fits-all. Some people need beta-blockers to calm dangerous spikes. Others require fludrocortisone to hold onto salt and water. Lifestyle tweaks matter too—increasing salt and fluid intake, wearing compression stockings, avoiding sudden movements. It’s not glamorous, but it works.
The posts below cover real cases, medication comparisons, and practical strategies from people who’ve lived with this. You’ll find guides on how to track your symptoms, which drugs help most, and what to ask your doctor when standard treatments fail. This isn’t theory. It’s what actually helps when your body won’t cooperate.
