PUD can lead to various symptoms, but up to 70% of patients may not experience any symptoms. Diagnosing PUD can be challenging due to the unreliability of individual symptoms and signs. PUD can have serious complications if left untreated. Despite its significance, there is a lack of studies measuring the awareness of PUD among the population in Al-Ahsa, Saudi Arabia. Therefore, this study aimed to assess the level of awareness of PUD among the general population in Al-Ahsa.</p><p><strong>Methodology: </strong>A cross-sectional study was conducted in Al-Ahsa, Saudi Arabia, from September to December 2023. The study included 399 adult residents of Saudi Arabia who agreed to participate. A convenient nonprobability sampling technique was used to collect data. An online self-administered questionnaire, distributed through social media platforms, was used to gather information on participants' awareness of PUD.
