Abstract

Background: Lactose intolerance is a frequent disorder characterized by gastrointestinal symptoms (such as nausea, bloating, and discomfort) following dairy product consumption. LI can be considerably decreased with simple understanding of symptoms and the use of milk substitutes.  Aim: The goal of this study was to look into the prevalence of lactose intolerance and its relationship to nutrition and dietary habits in Jazan, Saudi Arabia. Methods: This study used a cross-sectional descriptive design with a sample of 283 participants who met the qualifying requirements. A questionnaire was used to collect the data, which was then analyzed using statistical tools for social sciences (SPSS) and Microsoft Excel. Results: Dairy/dairy products were highly consumed on daily basis (64.7%) accompanied by abdominal distention and gases (18%), yet, only 13.8% had been diagnosed with lactose intolerance. The magnitude of lactose intolerance was mainly in late childhood (11-20 years) and emerging adulthood (21-30 years) (56.4%). only 36% had good knowledge about the disorder, with females had significantly higher levels of awareness compared to males (p<0.05). Conclusion: Almost one-third of the population in Jazan had good knowledge on lactose intolerance with females having significantly higher levels.
