New-Onset Illness Anxiety Disorder After Heliobacter Pylori Infection: A Case Report

Abstract

In this study, we present a case of new-onset illness anxiety disorder (IAD) in a 21-year-old female patient after Heliobacter pylori infection. The patient experienced a distressing preoccupation with having or acquiring a serious illness with mild somatic symptoms for more than six months. IAD adversely affected our patient’s life and made her engage in excessive care-seeking behaviors and maladaptive avoidance in some instances. In this case, we highlight the unique presentation of symptoms related to illness anxiety disorder and H. pylori infection. Furthermore, we discuss the possible psychosocial factors that are considered risk factors for developing IAD. We also discuss the pharmacological and psychological treatment options for patients with such a presentation.
