Few studies have described that diabetes mellitus (DM) is a common non-communicable disease reported during Hajj; however, most of these studies did not inspect the acute complications of DM and its manifestations among pilgrims.

This study found that foot injury is the most reported acute complication among participants during Hajj, followed by hyperglycemia, then hypoglycemia.

This finding indicates the importance of foot care among pilgrims with diabetes especially that they may walk for long distances as part of Hajj rituals.

Also, this study described the most common manifestations that are usually associated with hyperglycemia and hypoglycemia among Hajj pilgrims.
