Overview

Otitis Externa
Otitis externa, commonly called swimmer’s ear, is inflammation or infection of the outer ear and ear canal. It may develop suddenly or persist as a chronic problem. Bacterial infection is a common cause, particularly after water remains in the ear canal, although fungi and other causes are possible. Symptoms can include ear pain, itching, redness, swelling, drainage and discomfort when the outer ear is touched or moved.
Prediabetes
Prediabetes means blood glucose levels are higher than normal but not yet in the range used to diagnose type 2 diabetes. It often develops because the body becomes less responsive to insulin, causing glucose to remain elevated in the blood. Prediabetes may have no obvious symptoms and is often discovered through blood testing. Without appropriate lifestyle changes and follow-up, some people progress to type 2 diabetes. Early identification provides an opportunity to address modifiable risk factors and reduce future complications.

Diagnosis

Otitis Externa
Otitis externa is usually diagnosed from symptoms and examination of the outer ear and ear canal. The healthcare provider looks for redness, swelling, scaling, discharge or other signs of inflammation and infection. Pain when the outer ear is moved may support the diagnosis. Ear drainage may occasionally be tested when an infection does not improve or when the cause is uncertain. The examination also helps distinguish otitis externa from middle-ear disease and other causes of ear pain.
Prediabetes
Prediabetes is diagnosed with blood glucose testing rather than symptoms alone. Common tests include fasting plasma glucose, hemoglobin A1C, and an oral glucose tolerance test. Results are interpreted according to established diagnostic thresholds and may need confirmation depending on the circumstances. A clinician may also assess blood pressure, cholesterol, weight, waist circumference, family history, and other diabetes risk factors. Regular follow-up testing may be recommended because glucose levels can change over time.

Prevention

Otitis Externa
Keep the ears dry after swimming or bathing and avoid swimming in polluted water. Do not insert cotton swabs, fingernails or other objects into the ear canal because they can damage the skin. People who frequently develop swimmer’s ear may be advised by a healthcare provider about appropriate ear-drying measures. Hair sprays and dyes should be kept out of the ear canal. If an external ear infection develops, complete the recommended treatment to reduce the chance of persistent or more severe infection.
Prediabetes
Prediabetes can often be managed and, in many people, progression to type 2 diabetes can be delayed or prevented through sustained lifestyle changes. Regular physical activity, a balanced eating pattern, maintaining or reaching a healthy weight when appropriate, and avoiding tobacco can reduce metabolic risk. People at increased risk should undergo recommended glucose screening. Follow-up testing is important because prediabetes can progress over time. A healthcare professional can help create an individualized prevention plan based on overall risk.

Risk Factors

Otitis Externa
Risk factors include frequent swimming, exposure to contaminated water, moisture trapped in the ear canal and repeated irritation or injury to the canal skin. Cleaning the ears with cotton swabs or inserting other objects can damage the protective skin and increase risk. People with chronic skin conditions or allergies affecting the ear may also develop recurrent external ear inflammation.
Prediabetes
Risk factors for prediabetes include overweight or obesity, increased waist circumference, physical inactivity, family history of type 2 diabetes, increasing age, previous gestational diabetes, high blood pressure, abnormal cholesterol levels, and certain ethnic or genetic backgrounds. Polycystic ovary syndrome and other conditions associated with insulin resistance can also increase risk. Risk rises when several factors occur together, but prediabetes can develop even without every recognized risk factor.
