Biochemical and anthropometric changes during Ramadan among type 2 diabetes mellitus patients

In this study, our aim was to assess the impact of fasting during Ramadan on biochemical and anthropological factors in patients with type 2 diabetes and compare them with those who did not fast. This was a prospective study. It was carried out in the city of Yazd, Iran, during Ramadan of 2016.

This study showed that the mean BMI in three groups significantly decreased, and the highest decrement was seen in group 1 at the end of Ramadan ( p value 0.01). Fructosamine was increased in all groups, and the highest increment was seen in group 2 after Ramadan ( p value
