Aims:
Insulin requirement varies between patients with diabetes due to insulin resistance. The clinical profile of patients based on their insulin requirement has not been studied earlier. We stratified the patients based on total daily insulin requirement (TDIR) and studied their clinical profile and carbohydrate consumption.
Materials & Methods:
Sixty patients with type 2 diabetes (aged 30-75 years, using stable insulin dose for last 6 months, HbA1c between 6-7.5%, negative screening tests for Acromegaly and Cushing's disease) participated in this clinical observational study. All patients with major illness, surgery or diabetic ketoacidosis were excluded. The patients were divided into 3 groups: Group 1 (TDIR<1 U/kg, n=30), Group 2 (TDIR 1-2 U/kg, n=20) and Group 3 (TDIR>2U/kg, n=10). Data are presented as mean±S.D and comparison between three groups was done using one way ANOVA test.
Results:
The patients (27M: 33F) had mean age 54.3 ± 12.3 years, diabetes duration 10.1±4.7 years and an A1c of 7±0.38%. Patients in group 3 had lower body weight, BMI and highest carbohydrate consumption when compared with the other two groups (P<0.05). Hypoglycemic episodes and complications did not differ between the groups.
Conclusion:
Our data showed that the low body weight and high carbohydrate intake are associated with increased insulin requirement. The clinical implications of our study are to check the carbohydrate intake in patients with high insulin requirement.
