Hearing Loss and Hypertension: A Literature Review.

Hypertension is a condition in which there is an abnormal blood pressure with a systolic pressure of more than 140 mmHg and a diastolic pressure of more than 90 mmHg. It has been cited that hypertension can cause hearing loss. To understand the association between hypertension and hearing loss, a systematic review has been carried out in Pubmed Central, Google Scholar, EBSCO, Web of Science, Indian Science Abstracts, J Gate, Proquest, and Shodh Ganga. This review included original articles published on or after 2016 with cross-sectional study design, retrospective study design, and longitudinal design and excluded case reports and letters to the editors. Out of the 11,977 articles, only ten articles were finalized. These 10 articles stated a possible association between hypertension and hearing loss by explaining that Cochlear microcirculation change resulted in tissue hypoxia that caused hearing loss.
