Introduction:
Diabetes mellitus is a heterogenous disorder characterised by hyperglycaemia, insulin deficiency and insulin resistance is increasing economic and health burden throughout the world. American diabetes association defines diabetes as a metabolic disease characterised by hyperglycaemia resulting from defects in insulin secretion, insulin action or both.(1)People with diabetes spend up to 8000 hours per year managing their diabetes outside medical setting (2).This disease often requires various daily tasks such as checking blood glucose levels as well as coherence to many complicated medical regimens (3). Diabetes is often accompanied by risk factors such as obesity, hypertension, hypercoagulability, systemic inflammation and dyslipidaemia, which increases CVD death rates.(4).India is the epicentre of diabetes mellitus and in 2017 it was found that India is the second largest country having 73 million diabetic patients after china.(5).An average Indian exhausts around 5-30% of his house hold earnings on the management of diabetes alone which increases the burden of the nation.(6-8). There is a strong evidence shown by various randomised trials that lifestyle interventions like healthy diet, physical activity and weight loss decreases risk of developing type 2 diabetes (9-12).Recently it has been postulated that dietary modification can preserve B cell mass thereby reversing the progression of type 2 diabetes mellitus.(13-15).It has been shown that inspite of maintaining blood glucose levels below a threshold for diabetes treatment some people develop micro and macro vascular complications from prediabetes even before onset of type 2 diabetes mellitus.(16,17). Around 10% prediabetic subjects develop type 2diabetes each year.(18)
The aim of our study was to determine the relationship between vitamin D and physical exercise on glycaemic control in type 2 DM patients.
