Cochlear disorders and their relationship with cardiometabolic diseases

Abstract:

Currently, cardiometabolic diseases are a risk factor for those who suffer them. Meanwhile, their prevalence rises due to the multiple changes that globalization has caused, with more people suffering from these diseases due to their lifestyle. Amongst the most prevalent, diabetes mellitus, hypertension and dyslipidemias can be mentioned. These pathologies have been associated with changes in audition patterns and diverse studies have focused on determining their true pathology. Structural and/or functional changes can be a common factor for these three diseases. The relation with Diabetes Mellitus has been made mainly through the sustained maintenance of glycaemia levels, which leads to changes inside the cochlear system, which in turn pbkp_redisposes for long-term hearing deterioration in DM1 and DM2 patients. Similarly, its association with hypertension has been studied, observing rise in pressure inside the middle ear, which can cause hemorrhaging and structural changes in the vascularity of this level. In regards to dyslipidemias, its pathology is less precise and the more viscous characteristics of the blood in the ear and a decrease on its oxygen levels has been proposed. All of these theories tend to coexist in these pathologies even if they are not associated with each other. Therefore, these diseases must be studied in depth in order to determine the true role that each of these have in the hearing system, with the purpose of developing preventive methods and treatment measures in these very common ailments capable of causing hearing damage.
