Men diagnosed with celiac disease are in earlier scientific studies known to be less troubled by their experiences of living with disease than women with celiac disease. Previous studies, concentrating on men with celiac disease have been mostly quantitative, and the studies has dealt with physiology and pathology. The aim of this study was to give voice to young men with screening-detected celiac disease and to highlight the situations that they encounter in their daily lives five years after the screening. Seven Swedish young men were interviewed. They had been diagnosed with celiac disease as 12-13 years-olds through a large Swedish school based celiac screening-study. The semi-structured interviews were analyzed from a gender perspective using content analysis. The findings resulted in a main theme, conquering the disease and becoming a man, which was underpinned by several themes and sub-themes. The analysis showed that the young men’s experiences of living with celiac disease in their daily life, largely depended on their use of characteristics known to be in accordance with dominating masculinity; such as being self-assured, demanding, and behaving authoritative. In food situations, when the young men had the ability to make use of such characteristics in their informal group, they experienced much less negative aspects of the disease. If the young men did not have a position in their informal group where they could develop those features, their situation was expressed as being tough, they were bullied and withdrew from social meals. It seemed important for the young men to dissociate themselves from being seen as a person who had a life-long chronic disease.
