Background The association between highly stressful life experiences and morbid obesity is well documented internationally, but this knowledge is not incorporated to any great extent in Norwegian clinical practices. We have studied the reports of previous life stresses from a sample of Norwegian patients under assessment for morbid obesity at a centre where the topic of life experiences was included during the recording of patient histories. Material and method In the summer of 2018, an invitation to participate in the study was distributed to the last 200 patients to have been examined at the Regional Centre for Morbid Obesity in Bodo. Information on lifetime adversity was collected in clinical interviews. Data were retrieved from the patient's discharge summaries, and these texts were analysed using a qualitative approach. Stressful life experiences were divided into twelve categories. Results The study recruited 70 participants (57 women) with morbid obesity. Of these, 64 (91 %) related at least one significant and stressful life experience, and 39 (56 %) reported three or more different types. The most frequent types included serious relationship ruptures, parental neglect and other negative childhood experiences. Interpretation In a sample of Norwegian patients who were undergoing examination for morbid obesity there were many who reported distressing life histories. Lack of existential security in childhood, often linked to complex traumas, was prominent. In light of international research on the association between trauma and obesity, our results indicate that the patient's life history should be included in an assessment of patients with morbid obesity.
