A hemoglobin HbA1c test is standard for anyone at risk for diabetes or anyone with diabetes. The HbA1c is a blood test that shows a person's average blood sugar levels over a three-month period.

A 2025 analysis found hearing loss in 41% to 72% of people with diabetes, which was, on average, more than four times as often as in people without diabetes. People whose diabetes was less well controlled had greater hearing loss. Diabetes lasting 10 years or more doubled the risk.

Being mindful of how various factors affect blood sugar levels can help people avoid fatigue, curb cravings, boost mood, and manage weight.

People can keep blood sugar levels consistent by timing meals, practicing portion control, prioritizing healthy foods, staying active, avoiding smoking, and keeping a food log.
