Introduction: Hearing loss among elderly with metabolic disease is not widely been studied. However in this study, we are focusing on hypertension and diabetes mellitus without differentiating between types. Some of studies associated it with the medications taken that contribute to hearing loss. However, in these studies, we are not focusing on medication taken among subject but to configure the impact of metabolic diseases to hearing.The purpose of this paper is to investigate the prevalence of hearing loss among elderly with metabolic disease in Terengganu. In this study, the elderly who having metabolic disease is identified as having a cluster of hypertension, and diabetes mellitus (Type I and Type II).
Methods:The retrospective study was carried out of all 175 elderly ( > 60 years old ).
