Disease category
Prediabetes refers to a state where blood glucose levels are higher than normal but do not meet the diagnostic criteria for diabetes.
Core mechanism
The main related factors are insulin resistance, insufficient insulin secretion, overweight or obesity, and lack of physical activity.
Main causes · related factors
If insulin does not function sufficiently, glucose cannot enter cells effectively, causing blood glucose levels to rise.
Representative patterns
Most cases have no distinct symptoms, but in some individuals, the skin on the neck or armpits may darken or small skin growths may appear.
Individual differences
Risk varies according to age, family history, racial/ethnic background, hypertension, high cholesterol, gestational diabetes, cardiovascular disease, metabolic syndrome, polycystic ovary syndrome, and physical activity levels.
Diagnosis
Prediabetes can progress to type 2 diabetes, but progression can be slowed or prevented through lifestyle changes.
Management
Diagnosis primarily uses fasting plasma glucose tests and A1C tests, which reflect average blood glucose over the past approximately 3 months, with other blood tests considered as needed.
Treatment/Research Status
Fasting blood glucose requires at least 8 hours of fasting before the test and reflects only the status at a single point in time; therefore, results must be interpreted alongside testing conditions and whether repeated measurements were performed.
Read Evidence
The focus of management is weight management tailored to individual circumstances, regular physical activity, and a healthy, calorie-controlled meal plan.
Key Precautions
The treatment goal for prediabetes is to lower the risk of blood glucose worsening and progression to type 2 diabetes; in some cases, medical professionals may consider pharmacotherapy.

At a Glance

Prediabetes refers to a state where blood glucose levels are higher than normal but do not meet the diagnostic criteria for diabetes.

Most cases have no distinct symptoms, but in some individuals, the skin on the neck or armpits may darken or small skin growths may appear.

How the disease works

The main related factors are insulin resistance, insufficient insulin secretion, overweight or obesity, and lack of physical activity.

If insulin does not function sufficiently, glucose cannot enter cells effectively, causing blood glucose levels to rise.

Variations in presentation among individuals

Risk varies according to age, family history, racial/ethnic background, hypertension, high cholesterol, gestational diabetes, cardiovascular disease, metabolic syndrome, polycystic ovary syndrome, and physical activity levels.

The broad framework of diagnosis and management

Prediabetes can progress to type 2 diabetes, but progression can be slowed or prevented through lifestyle changes.

Diagnosis primarily uses fasting plasma glucose tests and A1C tests, which reflect average blood glucose over the past approximately 3 months, with other blood tests considered as needed.

Current status of treatment

Fasting blood glucose requires at least 8 hours of fasting before the test and reflects only the status at a single point in time; therefore, results must be interpreted alongside testing conditions and whether repeated measurements were performed.

The focus of management is weight management tailored to individual circumstances, regular physical activity, and a healthy, calorie-controlled meal plan.

The treatment goal for prediabetes is to lower the risk of blood glucose worsening and progression to type 2 diabetes; in some cases, medical professionals may consider pharmacotherapy.

How to read clinical trials

NCT01396954 is registered as an observational study, but since there are no results and the registration status is unclear, treatment effectiveness or adherence to standard care cannot be determined by study registration alone.

Points to verify during clinical consultations

In clinical practice, recent blood glucose test results and fasting status, changes in weight, activity, and diet, family history and comorbidities, history of gestational diabetes, follow-up examination plans, and the need for medication can be confirmed.
