Evaluation of the Effects of Dyslipidemia on Hearing in Patients with Type 2 Diabetes Mellitus.

Abstract

Modernization has led to change in life style and physical inactivity which are playing a major role in increasing the number of people with diabetes and dyslipidaemia, Different types of hearing loss in diabetic patients have been reported which shows progressive, gradual, bilateral sensorineural loss. The primary aim of the present study is to evaluate the effects of dyslipidemia on hearing in patients with type 2 diabetes mellitus. A comparative study was conducted where patients were divided into 4 groups-Type II diabetes mellitus with dyslipidemia,Type II diabetes mellitus with normal lipid profile, Only Dyslipidemia,Normal subjects. A total of 128 participants were enrolled in the study. The Diabetes patient was determined by the FBS, PPBS and Hba1c levels. Dyslipidemia determined by LDL,HDL,VLDL.Patients with Type 2 diabetes mellitus and dyslipidaemia was evaluated for the presence of hearing loss with the help of PTA. Prevalence of hearing loss among patients with Diabetes and Dyslipidaemia was 65.7%, 40.6% in Type II DM with normal lipid profile patients, 18.75% in patients with dyslipidaemia. Statistically significant association of hearing loss was noted in patients with diabetes mellitus and dyslipidaemia. Although hearing loss is multifactorial, control of the risk factors like dyslipidaemia in diabetes mellitus definitely halt the process of auditory damage. As observed from this study, poor glycaemic control, associated other co-morbidities were contributing factors for hearing loss. Healthy life style with early recognition of these diseases helps in preventing further damage.
