Can Trauma Weaken Your Immune System? Exploring the Mind-Body Connection


At The London Clinic of Nutrition, we take a functional medicine approach to health. This means we go beyond simply treating symptoms and instead, focus on identifying the root causes of your health concerns. One area we’re passionate about exploring is the link between trauma and overall health.

In this blog, we’ll delve into the question: Can trauma weaken your immune system?


What is Trauma?

Trauma is an emotional response to a distressing event that overwhelms our ability to cope. These events can be big or small, and could include accidents, violence, abuse, or even the loss of a loved one.

There’s also a concept called developmental trauma, which refers to negative experiences in childhood that can have lasting effects on physical and mental health.

The Impact of Early Life Experiences

The link between our experiences, particularly in early life, and our long-term health is a growing area of research. A large and influential study by the Centers for Disease Control and Prevention (CDC) – the Adverse Childhood Experiences (ACEs) Study – explored the connection between childhood adversity and health outcomes in adulthood.

This study found that experiencing challenging experiences in childhood, such as abuse, neglect, or household dysfunction, is actually quite common.  The more of these adverse experiences (ACEs) a person goes through, the more likely they are to develop health problems later in life.  These health issues can range from chronic conditions like heart disease or diabetes to mental health struggles and substance abuse.

The ACEs study highlights the importance of creating safe and supportive environments for children.  

How Can Trauma Affect Your Health?

When we experience trauma, our body’s natural stress response system kicks in. This system is designed to help us deal with danger, but when trauma is unresolved, this stress response can become chronic.

Studies, like one published in the prestigious Nature Journal by Sloane et al. (2018), have shown a connection between trauma and the immune system. The immune system is our body’s defence against illness.  This research suggests that chronic stress from unresolved trauma can impact the immune system, making us more susceptible to various health problems.

These problems can manifest in a number of ways, including:

  • Digestive issues (irritable bowel syndrome, bloating, constipation)
  • Sleep problems (difficulty falling asleep, restless sleep)
  • Fatigue and low energy
  • Headaches and muscle tension


The Impact of Trauma: A Functional Medicine Perspective

At The London Clinic of Nutrition, we frequently see a link between unresolved trauma and immune system dysfunction.  Many patients experiencing conditions like autoimmune diseases, chronic fatigue, and fibromyalgia often have a history of:

  • Early Childhood Bonding Issues: A lack of secure attachment or nurturing care in early life can prime the immune system for a heightened stress response.
  • Unhealthy Parental Relationships: Dysfunctional family dynamics, including excessive discipline, can contribute to chronic stress and immune system dysregulation.


The Straw That Breaks the Camel’s Back

We observe that a primed immune system can become overwhelmed, similar to “the straw that breaks the camel’s back” analogy.  While the body is generally equipped to handle challenges like toxins or infections, an already stressed immune system due to unresolved trauma can become susceptible to a variety of triggers later in life.  These triggers could include:

  • A bout of gastroenteritis
  • Experiencing a stressful event like a break-up or job loss
  • Chronic overwork and burnout

The consequence of this overwhelmed immune system can be a cascade of health issues, often presenting with a variety of diagnoses.

Healing from the Inside Out: Functional Medicine’s Approach

As we’ve discussed, the key to addressing these issues lies not in focusing solely on the biology or symptoms themselves, but rather in helping the immune system return to a more balanced state.  We utilize various techniques  to support this process, including:

  • Identifying and Addressing Underlying Trauma: We work with our patients to understand their unique experiences and develop strategies to address the impact of past trauma.
  • Nutritional Support: A personalized nutrition plan can address any nutritional deficiencies that may be impacting your immune system or overall health.
  • Gut Health: Research suggests a strong link between gut health and the immune system. Our functional medicine approach may incorporate strategies to improve gut health, potentially boosting your immune function.
  • Stress Management Techniques: We can incorporate stress management techniques such as mindfulness practices or relaxation exercises to help you manage chronic stress and support your body’s natural healing abilities.

Taking Charge of Your Health

If you’ve experienced trauma and are struggling with ongoing health issues, you don’t have to suffer in silence.  Functional medicine offers a path to healing from the inside out.  By addressing the root causes of your health concerns, we can help you achieve optimal health and well-being.
