The Stellate Ganglion Block And My Insulin Resistance

How It Actually Worked In My Body

I did not get the stellate ganglion block because I thought it would help my metabolism. I got it because my nervous system has been running on emergency power since childhood. Trauma does not just live in memory; it lives in the autonomic nervous system. When the sympathetic system never stands down, the body stays primed for threat. Mine did — for decades.

Living in that state is not psychological. It is chemical. Chronic sympathetic activation releases norepinephrine and cortisol, which raise glucose, increase hepatic glucose output, and blunt insulin sensitivity.^{1, 2} Over time, the pancreas and liver compensate, and the result is a form of insulin resistance born from survival, not indulgence.

My insulin resistance is not about willpower. It is about physiology.

So I got the stellate ganglion block (SGB) to quiet the alarm, not to lose weight. I wanted my brain to stop scanning the horizon for the next hit. I wanted to know what baseline might feel like for someone not living in a war.

The surprising part is that my metabolism responded. Within days, my appetite leveled. Cravings calmed. My blood sugar felt steadier. My stomach unclenched. My sleep deepened. The constant sympathetic clamp let go. When that happened, my insulin sensitivity improved — not forever, but long enough to prove a point: the nervous system

The literature supports what my body told me. Sympathetic activation increases hepatic glucose production and induces insulin resistance.^{1, 3} Glucocorticoids elevate fasting glucose by driving gluconeogenesis and antagonizing insulin.² PTSD — especially in women — is consistently associated with higher rates of type 2 diabetes and metabolic syndrome.^{4, 5}

None of that is fringe. It is endocrinology.

SGB interrupts that sympathetic loop by blocking the cervical sympathetic chain — a primary node in the fight-or-flight circuit.⁶ When that circuit gets space, the body recalibrates. Cortisol drops. The liver stops dumping sugar like it’s prepping for famine. Insulin finally gets a window.

It did not cure my insulin resistance. Nothing that simple exists. But it temporarily lowered the metabolic cost of being alive with CPTSD. For the first time in a long time, my body was not fighting me.

My metabolism is not stubborn. It is tired. It has been running a survival protocol since childhood, since pregnancy, since NICU trauma, since grief. Of course that touches insulin. Of course that touches glucose. Of course that touches appetite and weight.

When the alarm finally fell silent — even for weeks — my body remembered a different way to live.

Common Questions Women Ask About SGB, Trauma & Metabolism

Women who arrive here are often searching for answers about the intersection of trauma, nervous system dysfunction, and insulin resistance. Common searches include:

“stellate ganglion block insulin resistance”
“stellate ganglion block metabolism”
“stellate ganglion block CPTSD”
“does trauma cause insulin resistance”
“nervous system and blood sugar”
“sympathetic nervous system weight gain”
“cortisol insulin resistance women”
“PTSD type 2 diabetes women”
“stress hyperglycemia mechanism”
“SGB Mounjaro”

This post is for the women whose labs read like “metabolic syndrome” and whose lives read like “war.”
