The exactly link between hearing loss and diabetes isn’t entirely clear, but it could be caused by nerve damage to the auditory nerve, said Diabetes.co.uk.
Having prolonged high blood sugar can affect the supply of blood or oxygen to the nerves and blood vessels inside the ear.
Over time, these blood vessels become damaged, which affects the patient’s ability to hear properly, it said.
“Diabetes has been linked to the development of hearing problems in various research studies,” said Diabetes.co.uk.
“While it unknown exactly why hearing loss is more common among people with diabetes, autopsy studies of diabetes patients suggest this association is caused by neuropathy (nerve damage), which is a common complication of both type 1 and type 2 diabetes.
