Does poor blood sugar affect hearing?

      临床对69例2型糖尿病患者与45例同年龄组的普通人进行了听力比较。研究者给这些病人分别进行纯音测听和耳声发射等检查。前者检测的是患者能听到的最小的分贝数,反映患者的主观听力;后者检测的是患者内耳听觉器官的功能,属于客观指标。结果发现,糖尿病患者纯音测听听力损害的发生率为40.6%,对照组仅为2.2%,两组间差异很明显。而耳声发射的异常检出率更高,且左耳更为明显。此研究表明糖尿病患者听力损伤非常普遍,应该早期诊断和干预。

      There are many diseases that cause hearing loss, not just high blood sugar.With the increase of people with high blood pressure, hyperlipidemia, and hyperglycemia, these diseases have become a major risk factor for presbycusis.

      Hypertension can cause systemic vascular disease, affecting the microcirculation of many tissues and organs of the body, including the inner ear microcirculation, resulting in lack of blood oxygen in the inner ear, leading to hearing loss.

      Long-term high blood sugar can cause damage to blood vessels and increase the risk of hearing loss.This is because blood sugar can damage the nerves and tissues in the ear and destroy the hearing ability.

      Deafness caused by hyperlipidemia mostly occurs in middle-aged and elderly patients, and the onset process is slow.The reason is that hyperlipidemia can lead to inner ear lipid deposition, increased lipid peroxide, inner ear cell damage, vascular atrophy, and ultimately deafness.In addition, due to high blood lipids, blood viscosity increases, platelet aggregation increases, and atherosclerosis is induced, resulting in slow blood flow in the inner ear and insufficient blood supply, leading to hearing loss.

5. In addition to drug treatment, patients with hyperlipidemia should eat less high-fat and high-cholesterol foods, which can prevent atherosclerosis and deafness caused by hyperlipidemia.
