Background: Body mass index (BMI) criteria are currently the primary focus in obesity treatment recommendations, with different treatment cutoff points based upon the presence or absence of obesity-related comorbid disease.

Aim: This project aimed to explore the relationship of body mass index with blood sugar.

Patients & methods: Seventy-one adult diabetic patients (36 males+35 females) were subjected to this study. Body mass index was calculated for each patient and random blood sugar was also measured.

Results: The highest mean value of BMI was among male & female patients in the age group 60-69 years old, which reached 36.57 & 32.74, respectively while the mean value of random blood sugar in males was among the age group 30-39 years which reached 258.88 mg/dL. But it was 295.0mg/dL among age group >70years in females.

Conclusion: It is concluded that obesity is an important risk factor for diabetes and there was a relationship between BMI and increased blood sugar
