ABSTRACT
Introduction: For the diagnosis of diabetes mellitus, various tests are available such as FBS (Fasting blood sugar), PPBS ( Post Prandial Blood Sugar), Oral Glucose Tolerance Test, Random Plasma Glucose Test, HBA1c, etc, of which HBA1c is considered to be the most standard test.1,2 As diabetes mellitus can be asymptomatic initially, it can lead to important complications such as neuropathy, nephropathy, retinopathy, cardiovascular diseases, etc if not detected early.3 Postural blood pressure measurement which diagnoses orthostatic hypotension is a cheap, easy and useful tool to predict HBA1c level even in asymptomatic diabetic patients. Methods: This is a randomized cross-sectional study of 100 diabetic patients attending Medicine OPD or admitted in our tertiary care hospital of South Gujarat. Pretested proforma was used to collect data after taking informed consent. Investigations including blood pressure measured with a standard Sphygmomanometer at the end of 3 min after standing and HBA1c as mentioned in the proforma was carried out. Final analysis has been done with Open EPI and SPSS software. Results: 33% of patients of our study population were found with abnormal orthostatic hypotension. Our data shows orthostatic hypotension is directly associated with high HbA1c, longer duration of DM, and higher value of BMI. No correlation was found between age and gender. Conclusion: Among diabetic patients, high HbA1c, prolong duration of DM and high BMI were associated with abnormal orthostatic hypotension, which can be alarming sign of complications of diabetes mellitus.
