In a world where modern medicine often focuses on treating symptoms with pills and procedures, Dr. Gabor Maté, a renowned Canadian physician and psychotherapist, offers a radically different perspective. In his international bestseller When the Body Says No: The Cost of Hidden Stress, Maté argues that the root cause of many chronic illnesses—such as cancer, addiction, and depression—lies not in genetics or biology alone, but in suppressed emotions and unhealed trauma. Drawing from decades of clinical experience and scientific studies, Maté’s work challenges the conventional separation of mind and body in Western medicine, urging us to address the emotional wounds that silently shape our health.

1. The Mind-Body Connection: Chronic Illness Starts with Emotional Repression

Maté asserts that the roots of most chronic illnesses are psychological and emotional, a perspective that starkly contrasts with mainstream medical practice. He points out a troubling statistic: 70% of adults in the United States are on medication, yet chronic diseases, obesity, addiction, and mental illness continue to rise. Why are we struggling despite advancements in science? Maté argues that modern medicine’s fatal flaw is its failure to integrate the mind and body. “The repression of anger leads to the chronic secretion of stress hormones, such as cortisol, that suppress the immune system,” Maté explains, citing research from his website (drgabormate.com). This suppression, he notes, has been linked to a wide range of conditions, from cancer and rheumatoid arthritis to migraines and fibromyalgia.

In his over two decades of family medicine, including seven years in palliative care, Maté observed a consistent pattern: patients with chronic illnesses often exhibited emotional shutdowns, particularly an inability to express anger. They were driven by a compulsive sense of responsibility for others, often at the expense of their own needs, and struggled to say “no.” This emotional repression, Maté argues, creates a physiological environment ripe for disease, a theory supported by studies showing that individuals who suppress emotions are at a 30% higher risk of developing depressive symptoms (Journal of Personality and Social Psychology, 2003).

2. Trauma Begins in the Womb: The Lasting Impact of Early Stress

One of Maté’s most profound insights is that trauma can begin even before birth. He explains that a stressed mother’s emotional state directly affects the fetus, shaping its brain development and physiology. “A stressed mother affects the physiology and brain development of the fetus,” Maté notes. “The impacts of that stress can be seen decades later by how they respond to stress as adults.” In Western societies, where many pregnant women work well into late pregnancy, this stress can imprint on the baby, influencing its future mental and emotional health.

Maté’s own life story as the Budapest-born son of Holocaust survivors underscores this point. As an infant, his mother left him in the care of strangers for weeks to save his life during the Holocaust, an experience he believes left him with lifelong themes of abandonment, loss, and rage (theconversation.com, 2025). This early trauma, he argues, is not an isolated case but a universal phenomenon that shapes who we become, often manifesting as chronic illness or mental health struggles later in life.

3. Addiction as a Coping Mechanism: Reframing the Problem

Maté’s perspective on addiction is both compassionate and revolutionary. “Addiction isn’t the problem, it’s the solution,” he states. He views addiction—whether to substances, behaviors, or even work—as a coping mechanism for unhealed emotional trauma. “We turn to substances or behaviors to soothe wounds,” Maté explains, a theory backed by a study in the American Journal of Preventive Medicine, which found that 70% of individuals in drug treatment programs report having experienced trauma.

Rather than asking “Why the addiction?” Maté urges us to ask “Why the pain?” This shift in perspective encourages self-compassion and a deeper understanding of the emotional wounds driving addictive behaviors. For Maté, healing addiction requires addressing these underlying emotions, a process that goes beyond the surface-level interventions of most treatment programs. His own struggles with addiction and ADHD, which he has openly discussed, lend a personal authenticity to his approach, making his insights resonate with those who feel misunderstood by traditional medical frameworks.

4. Depression and the Weight of Suppressed Emotions

Maté challenges the conventional view of depression as a chemical imbalance, such as low serotonin levels. Instead, he identifies suppressed emotions as the true root cause. “When you bury your pain, sadness, or anger, it doesn’t disappear,” he warns in the thread. “It lives in your body, silently shaping your thoughts.” This emotional repression leads to feelings of hopelessness, emptiness, and depression, a connection supported by the 2003 study mentioned earlier, which linked emotional suppression to a higher risk of depressive symptoms.

Healing, according to Maté, requires reconnecting with these buried emotions and feeling them without judgment. This process can be daunting, as it involves confronting pain that has been avoided for years, if not decades. However, Maté emphasizes that this emotional reconnection is essential for recovery, offering a path to liberation from the cycle of depression.

5. People-Pleasing as a Sign of Deeper Wounds

At first glance, people-pleasing might seem like a harmless trait, but Maté sees it as a symptom of deeper emotional wounds, often rooted in childhood. “Those raised in emotionally unstable environments learn to prioritize others’ needs before their own as a survival tactic,” he explains. This behavior, while adaptive in childhood, leads to a loss of connection with one’s own needs in adulthood, perpetuating a cycle of emotional suppression.

To break free, Maté recommends a three-step process: learning to identify your own needs, setting healthy boundaries, and reclaiming your sense of self. This journey requires processing suppressed emotions, which can be facilitated through therapeutic methods like Internal Family Systems, Somatic Experiencing, EMDR, Psychedelic-Assisted Therapy, and Maté’s own approach, Compassionate Inquiry. These methods, he notes, help individuals reconnect with their bodies and emotions, paving the way for true healing.

A Path to Healing: Reconnecting with the Body

Maté’s work is a powerful reminder that healing is not just about treating the body—it’s about addressing the mind and emotions as well. His insights challenge us to look beyond the surface of our struggles and confront the emotional wounds that shape our health. Fortunately, as Maté points out, healing is more accessible than ever before. The first step, he suggests, is free: reconnecting with your body and sensations. From there, therapeutic methods can provide the tools to process suppressed emotions and reclaim your well-being.

For those feeling stuck, Maté’s message is one of hope. Various resources available that can help individuals change their habits, routines, and mindset, fostering strength and discipline. Maté’s work, combined with such tools, offers a roadmap to break free from the hidden costs of suppressed emotions and live a healthier, more authentic life.

Conclusion: A Call to Emotional Awarenes

Gabor Maté’s insights into the mind-body connection are a wake-up call for a society grappling with rising rates of chronic illness and mental health struggles. By linking conditions like cancer, addiction, and depression to suppressed emotions and unhealed trauma, Maté challenges us to rethink our approach to health. His five key insights—ranging from the psychological roots of illness to the origins of people-pleasing—reveal the profound impact of emotional repression on our lives. But more importantly, they offer a path forward: by reconnecting with our emotions, setting boundaries, and seeking therapeutic support, we can break free from the cycles of pain that hold us back. In a world that often prioritizes quick fixes, Maté’s work reminds us that true healing begins with listening to what the body—and the heart—have to say.
