Type 2 diabetes mainly occurs in people over 40 years old. However, in recent years, many younger people are still being diagnosed with diabetes. Detecting and controlling the disease is extremely important, helping to prevent damage to blood vessels, nerves and other important organs, according to the health website Healthline (USA).

Changes in the ear that can be a warning sign of diabetes include:

Recurrent ear infections

There are many causes of ear infections, one of which is type 2 diabetes. Long-term high blood sugar damages the blood vessels in the inner ear, affecting blood circulation and nerve signals to the ear.

The result of this condition is a decrease in the ear's immunity, making it susceptible to recurring infections. Prolonged and slow-healing ear infections may require surgical intervention. In addition, patients should also follow some recommendations to prevent ear infections, such as not inserting cotton swabs into the ears and using earplugs when swimming.

Tinnitus

Tinnitus is not a common symptom of type 2 diabetes. However, high blood sugar can make it worse. This is because high blood sugar can damage the cochlea, leading to tinnitus.

Tinnitus is a condition in which the sufferer hears sounds like buzzing, hissing, or whistling even when there is no external sound. In addition, tinnitus can also be a sign of other health problems such as injury or ear infection.

Hearing loss

Hearing loss is a common consequence of aging. Older people are at higher risk for this condition. However, hearing loss can also be caused by other health problems, including type 2 diabetes.

Hearing loss often progresses slowly, making it difficult to detect. However, if a person often cannot hear what others are saying, or has to turn up the volume when listening to music or watching movies, it is a sign of hearing loss and should be examined, according to Healthline .
