Panic Attacks

Panic is a full-body alarm firing without a clear threat. We look at autonomic balance, breathing chemistry, blood sugar, thyroid, and inner-ear signals.

What you may be noticing

Out of nowhere, your heart races, your chest tightens, your hands tingle, and a wave of dread rolls in. You may feel you are dying or losing control. It peaks within minutes, then leaves you shaky and wary of the next one. You begin avoiding places where it happened.

Chest pain, fainting, or shortness of breath should always be evaluated medically first, especially the first time. Panic attacks are frightening but are not usually dangerous, and a medical evaluation confirms that. Medications are never changed on your own or without your prescriber.

Why it is rarely one thing

A panic attack is a real surge of the sympathetic nervous system, a fight-or-flight response arriving without an obvious external trigger. The question is what keeps that alarm so easy to set off.

Often the trigger is internal. A blood sugar drop releases adrenaline. Rapid, shallow breathing lowers carbon dioxide, which narrows blood vessels and produces tingling and lightheadedness. An overactive thyroid speeds the heart. Inner-ear signals that disagree with vision can create a sense of falling or unreality. Caffeine, alcohol rebound, poor sleep, and low vagal tone all lower the threshold. Your body is not working against you. It is communicating, and the nervous system is reading danger in the signals it receives.

Patterns we look for

• Autonomic balance and vagal tone, measured with heart rate variability.
• Breathing chemistry and carbon dioxide tolerance.
• Blood sugar instability and reactive hypoglycemia, sometimes tracked with a continuous glucose monitor.
• Thyroid function, including hyperthyroid patterns.
• Cortisol rhythm across the day rather than a single value.
• Vestibular findings and visual-vestibular mismatch.
• Iron, B12, magnesium, and vitamin D status.
• Heart rhythm, coordinated with your physician when palpitations are prominent.
• Gut-brain signaling and histamine patterns.
• Frontal lobe regulation of the limbic system.

How I evaluate it

The comprehensive functional neurological exam assesses autonomic responses from lying to standing, eye movements, vestibular reflexes, and balance, which often reveal why the body feels unsafe. Biofeedback and neurofeedback scanning can add a picture of autonomic and brainwave patterns.

Functional labs may include a comprehensive thyroid panel, fasting glucose and insulin, ferritin, B12, magnesium, vitamin D, a diurnal cortisol and hormone map, and inflammatory markers. I coordinate with your physician for heart rhythm testing when needed.

How we address it

Calm comes first. Regulation precedes endurance.

1. Rule out medical causes and coordinate with your prescriber.
2. Remove amplifiers: caffeine excess, blood sugar crashes, and alcohol rebound.
3. Retrain breathing toward slower, lower patterns that raise carbon dioxide tolerance.
4. Strengthen vagal tone and autonomic flexibility with brief practices such as humming and extended exhales, repeated through the day.
5. Rebalance physiology: thyroid, iron, minerals, and stable meals.
6. Use brain-based rehabilitation to settle vestibular mismatch and strengthen frontal regulation, working gently below your symptom threshold so the brain gathers evidence of safety.
7. Support therapy approaches that reduce avoidance and fear of sensations.

Understanding the mechanism is itself calming. Once you know that tingling hands reflect breathing chemistry, or that a wave of dread can follow a blood sugar drop, the sensations lose much of their power. Balance restores certainty, certainty creates safety, and safety creates self-trust.

When the body sends clearer signals, the mind can stand down too.
