Dopamine and Depression: The Metabolic Link You Need to KnowDopamine and Depression: The Metabolic Link You Need to Know
The Biology of Trauma™ With Dr. Aimie
Dr. Aimie and neuroscientist Dr. Kyle Bills talk about how dopamine, blood sugar and trauma-related biology shape addiction, anxiety and migraine. They discuss research on nerve stimulation, glucose phenotypes and the need for stable anchors in recovery and mental health.

Dopamine, Blood Sugar and Why Sobriety Can Feel So Hard
Episode Overview
- Dopamine is a learning signal tied to novelty and salience, not simply a “feel-good” chemical, and it is deeply involved in addiction and trauma patterns.
- Peripheral nerve stimulation at specific frequencies can trigger dopamine release and alter how alcohol and opiates change the brain, potentially easing withdrawal anxiety.
- Significant glucose dysregulation and hypoglycaemia can drive anxiety, migraines and severe mood issues, so continuous monitoring can reveal patterns missed by single lab tests.
- Chronic stress and trauma can exhaust metabolic and dopaminergic systems, lowering resilience and making everyday demands feel overwhelming.
- Recovery is more stable when self-worth is anchored to unchangeable foundations rather than fragile externals like jobs, other people’s opinions or performance.
“Dopamine is almost a little bit morally agnostic… dopamine isn’t good or bad per se. It depends.”
How do people cope with the challenges of staying sober? This conversation between medical doctor and trauma specialist Dr. Aimie and neuroscientist Dr. Kyle Bills offers a fresh angle: look at dopamine and blood sugar, not just willpower. Rather than framing addiction, anxiety or depression as simple “chemical imbalances”, they talk about unique metabolic phenotypes – the individual mix of dopamine, glucose regulation and hormones that shapes how someone feels, thinks and reacts. Dr.
Bills explains years of NIH-funded research showing that stimulating specific peripheral nerves at the right frequencies can trigger dopamine release in the brain, even changing how alcohol and opiates affect neural circuits. As he dryly puts it, “Dopamine is almost a little bit morally agnostic… it doesn’t necessarily make you feel good or bad.” For anyone in recovery, their discussion about withdrawal hits home. Dr.
Bills uses the image of being held under water to describe the panic of withdrawal, and Dr. Aimie links this to why people go back to substances or behaviours (including people-pleasing and perfectionism): the anxiety of stopping can feel unbearable without biological support. They also highlight how glucose swings and hypoglycaemia can drive anxiety, migraines and even severe psychiatric symptoms.
Case examples include people with massive blood sugar drops whose mood and autoimmune markers shifted when their metabolic issues were addressed, such as using ketogenic nutrition under medical care. Both keep circling back to a key idea: biology sets the stage for behaviour. Low blood sugar can make everyday tasks feel “too hard”, chronic stress can exhaust dopamine and resilience, and an unstable inner anchor makes relapse more likely when life changes.
Their blend of hard science, honest scepticism and practical curiosity makes this especially helpful for people in addiction recovery who suspect there’s more going on than just “white-knuckling it”. If your sobriety feels like a sprint you can’t keep up, could your dopamine and blood sugar be part of the story?
