Background and Aim: Cardiac autonomic neuropathy (CAN) is a common and often-underdiagnosed complication of diabetes mellitus (DM). Cardiac autonomic neuropathy is associated with increased mortality, cardiovascular disease, chronic kidney disease, and morbidity in patients with diabetes mellitus, but despite these significant consequences cardiac autonomic neuropathy often remains undiagnosed for a prolonged period. This is commonly due to the disease being asymptomatic until the later stages, as well as a lack of easily available screening strategies. Aim of the is to assess the autonomic nerve functions in diabetic patients and its manifestations.  Methods: The present study include 40 subjects in which 30 were diabetics and 10 were taken as controls from the medical wards of MNR Medical College Sangareddy, Telangana. Results & Conclusion: The diagnosis is made using multiple autonomic function tests to assess both sympathetic and parasympathetic function. The pathophysiology of cardiac autonomic neuropathy is complex, likely multifactorial, and not completely understood.Valsalva ratio test has lower values, both parasympathetic and sympathetic components of ANS has shown evidence of dysfunction.
