Résumé de When the Body Says No

In *When the Body Says No*, physician Gabor Maté argues that chronic emotional stress, particularly the suppression of anger and the inability to set boundaries, plays a significant role in the onset and progression of serious illness. Drawing on his clinical experience in family practice and palliative care in Vancouver, Maté connects prolonged psychological strain to conditions such as cancer, autoimmune disorders, multiple sclerosis, and ALS, proposing that the mind and body are not separate but expressions of one integrated system. Maté develops several distinctive frameworks. He describes the "biology of loss," in which early childhood experiences of neglect or emotional deprivation shape lifelong stress-response patterns, and the "false self" that children adopt to secure attachment by prioritizing others' needs over their own. He also explores the physiological mechanisms involved, including the hypothalamic-pituitary-adrenal axis and the effects of cortisol and repressed emotion on immune function. Case histories anchor these ideas, including patients with breast cancer, rheumatoid arthritis, and ALS whose lives reveal patterns of chronic self-sacrifice and unmet emotional needs. A recurring theme is the "disease-prone personality," which Maté associates with traits like compulsive caregiving, difficulty expressing anger, and an excessive sense of responsibility. He critiques conventional medicine for separating mind from body and argues that acknowledging emotions is not merely psychological but biologically protective. The book also examines research linking stress to immunosuppression and discusses the role of the nervous system in regulating health. While acknowledging that stress is not the sole cause of disease, Maté contends that emotional honesty, healthy anger, and the capacity to say no are essential to well-being. The title reflects his central claim that when people cannot assert themselves emotionally, the body eventually registers the refusal. The book combines scientific discussion, patient narratives, and Maté's own reflections, offering a perspective that has influenced both popular health writing and discussions of trauma's physical consequences.
