Dr Amy Bibby said: “Some people may experience more unusual symptoms and signs of diabetes.
“It is usually a range and combination of different symptoms that a patient will experience before being diagnosed with diabetes and it will vary case to case.
“Blood vessels can become damaged if a patient has high blood sugar.
“Hearing loss can be another more unusual, pre-diabetic symptom in those who have higher blood sugar.
“This is due to the blood vessels and nerves of the ears which are more likely to be damaged and therefore cause a loss of hearing.”
