People with prediabetes who successfully lower their blood sugar back to normal levels may cut their future risk of death due to heart disease by half, according to a 2025 study.

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.

A 2025 study suggested that people with diabetes who exercise regularly or in a “weekend warrior” pattern are significantly less likely to die earlier than peers who are inactive.

In a 2025 study, people who followed a Mediterranean diet, reduced their calorie intake, exercised at least 150 minutes a week, and received weight-loss support lowered their diabetes risk and lost more weight than those who only followed a Mediterranean diet.

Overweight or obese men diagnosed with prediabetes who received counseling on healthy eating habits and online support significantly improved their diets and reduced their risk for developing diabetes, according to a 2025 study.

A 2025 study suggested that women with diabetes are nearly twice as likely as men to have hidden heart disease. These women might especially benefit from early screening for problems in the small blood vessels of the heart.

Being mindful of how various factors affect blood sugar levels can help people avoid fatigue, curb cravings, boost mood, and manage weight. Blood sugar spikes after people eat carbohydrate-heavy foods, soon dropping again. Eating balanced meals and snacks that include protein, fat, and carbohydrates can maintain more stable blood sugar levels. 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.

Researchers have found that high blood pressure, diabetes, and smoking had the greatest association with the likelihood of a dementia diagnosis as people age. Managing these issues could offer protection.

People with prediabetes may be able to reduce their risk of developing type 2 diabetes with 150 minutes of moderate-intensity exercise per week, says a 2025 study. Exercise can help lower blood sugar and excess weight, the main risk factors for progression of prediabetes to type 2 diabetes.
