Stress Eating as a Response to Trauma

Stress eating, or emotional eating, is a common way people cope with overwhelming emotions. For those who have experienced trauma, food can become more than just nourishment - it can serve as a source of comfort, control, or even temporary escape. Understanding the biochemical processes at play can shed light on why this happens and how we can begin to heal.

Trauma as a Stress Response

Trauma is not just about an event itself—it’s about how the body responds to it. When we experience something distressing, our body enters a stress response - a survival mechanism designed to keep us safe. This can involve one of the four F's: fight, flight, freeze, or fawn. The body releases stress hormones like cortisol and adrenaline to prepare for immediate action.

However, when trauma is prolonged or unresolved, the body remains in this heightened state of alert, even when there is no immediate danger. This constant activation of the stress response can lead to long-term imbalances in the body, including the biochemical changes that contribute to emotional eating.

Biochemical Response to Triggers

When a person is triggered—whether by a memory, a situation, or even a feeling—the body responds as though it’s under threat. Here’s what happens biochemically:

✔ Cortisol Release – The adrenal glands release cortisol, the primary stress hormone, into the bloodstream. This hormone increases blood sugar levels to provide immediate energy for the body to react. However, elevated cortisol over time can lead to heightened cravings for sugar and high-fat foods, as the body seeks to replenish its energy reserves and soothe the effects of stress.

✔ Dopamine and Reward System – As the body seeks relief from emotional distress, food, particularly high-sugar or fatty foods, can trigger a release of dopamine, the "feel-good" neurotransmitter. This temporary surge of dopamine reinforces the behavior, leading to a cycle where emotional triggers are consistently met with food for comfort.

✔ Serotonin Imbalance – Trauma can also affect serotonin, a neurotransmitter responsible for mood regulation. Low serotonin levels are commonly linked to feelings of anxiety, depression, and impulsivity. Stress eating, particularly the consumption of carbohydrates and comfort foods, may serve as an attempt to boost serotonin levels temporarily.

✔ Gut-Brain Axis – The gut plays a critical role in emotional regulation. In response to trauma and chronic stress, the gut microbiome can become dysregulated. The gut is responsible for producing a significant amount of serotonin, and when it's out of balance, it can contribute to emotional instability and drive cravings for foods that offer temporary relief.

Understanding the Cycle

The body’s biochemical responses to trauma and stress often create a cycle. When a trigger causes a stress response, the body’s craving for food becomes an attempt to regulate these neurochemical imbalances. Over time, this cycle becomes ingrained, making it harder to break free.

Healing from the Biochemical Effects of Trauma

Healing involves addressing both the emotional and biochemical aspects of trauma. By understanding the underlying biochemical mechanisms, we can begin to break the cycle of stress eating and work toward creating a healthier relationship with food.
