ENT Complications of Diabetes: Can Diabetes Cause ENT Problems?
When people think about diabetes complications, they usually think about eye problems, heart disease, kidney damage and neuropathy. However, diabetes can also affect the ear, nose and throat (ENT) system.
Long-term high blood sugar can affect blood vessels, nerves and different tissues in the body. As a result, some people with diabetes may develop hearing problems, ear infections, nasal complications or throat infections.
1. Hearing Loss in Diabetes
Hearing loss is an important ENT complication that can occur in people with diabetes. The supplied content describes the risk of hearing loss as higher in people with diabetes compared with the general population.
Inside the inner ear are specialized hair cells that help detect sound and transmit signals to the brain through nerves. These cells depend on an adequate blood supply.
Long-term high blood sugar can contribute to changes in blood vessels. The formation of advanced glycation end products (AGEs) may affect the inner lining of blood vessels, potentially reducing blood supply.
Signs of Hearing Loss
Hearing loss can develop gradually, so some people may not immediately realize that their hearing has changed.
Possible signs include:
- Frequently increasing the television volume
- Asking other people to speak louder
- Repeatedly asking people to repeat themselves
- Difficulty understanding speech in noisy places
- Difficulty hearing in restaurants, bus stations or railway stations
This type of hearing problem may be evaluated through audiology tests.
2. Ear Infections in Diabetes
Another ENT problem seen in people with diabetes is external ear infection, also known as otitis externa.
These infections may involve:
- Bacterial infections
- Fungal infections
Some people may experience:
- Itching inside the ear
- Discharge from the ear
- Ear discomfort
If an ear infection develops, especially in someone with diabetes, it is important to seek appropriate ENT care.
When poorly controlled diabetes is present, an external ear infection can become more serious and may spread to the bone beneath the ear. Early diagnosis and treatment can help reduce the risk of complications.
3. Nose and Sinus Problems
People with diabetes may also experience nasal problems such as chronic atrophic rhinitis, with symptoms including prolonged nasal discharge, sneezing and allergy-related symptoms.
Another serious concern mentioned is mucormycosis, a fungal infection that can occur more readily in people with poorly controlled diabetes.
Early recognition and treatment of such infections are important because serious complications can develop if they are not addressed promptly.
4. Throat Complications
Diabetes can also be associated with throat infections.
Some people may develop white or red patches in the throat due to fungal infections such as candidiasis.
A burning sensation in the throat may also be noticed.
Maintaining good blood sugar control and appropriate oral hygiene can be important in reducing the risk of such problems.
How Can Diabetic Patients Reduce ENT Complications?
1. Keep Blood Sugar Under Control
The supplied guidance recommends aiming for:
- Fasting blood sugar: below 130 mg/dL
- Two-hour post-meal blood sugar: below 180 mg/dL
- HbA1c: below 7%
Keeping blood sugar under appropriate control is an important part of reducing diabetes-related complications.
2. Control Blood Pressure and Cholesterol
Blood pressure and cholesterol levels should also be monitored and managed appropriately, particularly in people with diabetes.
3. Avoid Smoking
People who smoke should make an effort to stop, as smoking can add to overall health risks.
4. Do Not Put Earbuds or Hard Objects Inside the Ear
Avoid using earbuds, pins or other hard objects to scratch or clean inside the ear.
Even a small injury to the skin of the ear canal can increase the risk of infection, particularly in people with diabetes.
5. Pay Attention to Chronic Nasal Problems
People who have chronic allergic rhinitis or related nasal problems may benefit from measures such as steam inhalation as part of their routine care.
Persistent nasal symptoms should be evaluated when necessary.
6. Maintain Good Oral Hygiene
Oral hygiene is another important part of preventing ENT-related infections.
Simple habits include:
- Rinsing the mouth with water after eating
- Brushing in the morning
- Brushing again in the evening
- Maintaining regular oral cleanliness
These habits can help maintain better oral and throat hygiene.
Final Takeaway
Diabetes can affect more than the eyes, kidneys, heart and nerves. Hearing loss, ear infections, nasal problems, fungal infections and throat complications can also occur.
Pay attention to signs such as gradually reduced hearing, difficulty hearing in noisy environments, ear itching or discharge, persistent nasal symptoms and throat burning or patches.
Good blood sugar control, avoiding smoking, protecting the ears from unnecessary injury and maintaining proper oral hygiene are important parts of diabetes care.
