This study aimed to evaluate knowledge gaps, psychological burden and patient-reported symptom severity and daily functioning (PR-SSDF) among Chinese patients with AIG.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A questionnaire-based cross-sectional survey was distributed to 130 eligible AIG patients, of whom 113 participants fully completed the survey, achieving a response rate of 86.9%. The questionnaire collected information on sociodemographic characteristics, disease-related knowledge, lifestyle behaviors, as well as AIG-related impacts on patients\u2019 daily activities and mental wellbeing.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The majority of respondents were female (66.36%), with the highest proportion in the 40\u201365\u202fyears age group (64.55%). A significant portion of patients had been diagnosed with AIG for less than a year (49.09%). Most resided in urban areas (63.64%). Perceived knowledge about AIG was found to be limited, with only a minority of patients achieved adequate disease comprehension. The majority of patients reported experiencing symptoms that affected their daily life and occupational activities. A substantial proportion of patients also reported experiencing extra-gastrointestinal symptoms and psychological distress following diagnosis. The majority of patients were covered by some form of medical insurance, with the largest group having employee medical insurance (87.27%).<\/jats:p>\n                  <\/jats:sec>\n
