 The study aimed to investigate what kind of information users seek in a health chatbot providing support on gestational diabetes mellitus, GDM, when and how the chatbot is used, and to categorize questions the chatbot was unable to answer. The results showed that frequently asked questions mirrored the cornerstones of GDM treatment and may indicate that the chatbot is used as a low threshold way to access information already provided by healthcare services. The study highlights the importance of promoting and integrating the chatbot into anti-natal care and continuously improving its content to provide relevant information.
