Could Ear Problems Be a Sign of Diabetes? Experts Weigh In

A recent claim suggests that various ear-related disorders may signal diabetes.

In a recent interview with Daily Mail, audiologist Dr. Rob Ormerod emphasized how various health conditions, particularly diabetes, can impact ear health. He explained that fluctuations in blood sugar levels among diabetic patients can disrupt blood flow, potentially damaging the blood vessels in the inner ear.

Dr. Ormerod also highlighted a key connection between diabetes and hearing loss. “Research shows individuals with diabetes are twice as likely to experience hearing loss,” he noted. Age-related hearing loss is often compounded by the effects of diabetes, with the damage developing gradually. Because of this, many patients may not immediately recognize their hearing decline. Struggling to follow conversations or needing to increase the volume of electronic devices frequently can be early signs of hearing loss.

Diabetes also increases the risk of ear infections. Due to reduced blood flow, the immune system’s ability to fight off infections is compromised, making diabetic individuals more vulnerable to ear infections.

Tinnitus, the sensation of hearing ringing or buzzing in quiet environments, is another potential sign of diabetes. Dr. Ormerod explained that the inner ear, specifically the cochlea, relies on a steady supply of oxygen and glucose to function correctly. Disruptions in blood sugar levels, caused by insulin imbalances in diabetic patients, can affect the cochlea and result in tinnitus.

Diabetes is a condition in which the body does not properly respond to insulin, the hormone responsible for regulating sugar absorption into the bloodstream. Left unchecked, it can lead to various complications, including issues with hearing.

In addition to hearing loss, other early signs of diabetes include increased urination, persistent thirst, fatigue, unexplained weight loss, itching around the genital area, and blurred vision.
