Prediabetes: The Early Warning Signs You Should Never Ignore
Prediabetes is a common condition that often develops quietly, without causing obvious symptoms. Many people only discover they have elevated blood sugar levels during a routine health assessment or blood test.
The good news is that identifying prediabetes early provides an opportunity to reduce your risk of developing type 2 diabetes through appropriate medical guidance and healthy lifestyle changes. Early intervention can make a significant difference to long-term health outcomes. Diabetes South Africa
At Dr Esti-Mari Knipe & Associates, our Waterkloof practice provides preventative healthcare and comprehensive GP assessments for patients from Waterkloof, Brooklyn, Menlo Park, Lynnwood, Garsfontein and Pretoria East. We believe that early detection is one of the most effective ways to protect your future health.
What Is Prediabetes?
Prediabetes means that your blood glucose (blood sugar) levels are higher than normal but not high enough to meet the criteria for diabetes.
Although prediabetes is not diabetes, it indicates that your body is beginning to have difficulty regulating blood sugar effectively. Without appropriate intervention, some people with prediabetes will go on to develop type 2 diabetes over time. Diabetes South Africa
Importantly, prediabetes often develops over several years, providing an opportunity for early identification and preventative care.
Does Prediabetes Cause Symptoms?
One of the challenges with prediabetes is that many people experience no symptoms at all.
This is why routine health assessments and appropriate blood tests are so valuable.
Some people may notice symptoms such as:
- Increased thirst
- Frequent urination
- Fatigue
- Blurred vision
However, these symptoms are more commonly associated with diabetes rather than prediabetes. Many individuals with prediabetes feel completely well. Diabetes South Africa
Who Is at Higher Risk?
Your risk of developing prediabetes may be higher if you:
- Are overweight or obese
- Have a family history of type 2 diabetes
- Have high blood pressure
- Have raised cholesterol levels
- Are physically inactive
- Previously had gestational diabetes during pregnancy
- Have polycystic ovary syndrome (PCOS)
- Are aged 45 years or older
These risk factors help your GP decide whether diabetes screening is appropriate. South African primary care guidance recommends screening based on age and individual risk factors rather than testing everyone routinely. Knowledge Hub
How Is Prediabetes Diagnosed?
Your GP will begin by discussing your medical history, lifestyle and any risk factors.
If appropriate, blood tests may be recommended. These may include:
- Fasting blood glucose
- Oral glucose tolerance test (OGTT)
- HbA1c in selected circumstances
The most appropriate investigation depends on your individual clinical situation and your doctor's assessment. Diagnosis should always be based on appropriate laboratory testing rather than symptoms alone. Diabetes South Africa
Why Early Detection Matters
Prediabetes provides an important opportunity to improve long-term health before diabetes develops.
Identifying elevated blood sugar early allows your GP to work with you on:
- Healthy eating habits
- Weight management
- Regular physical activity
- Blood pressure control
- Cholesterol management
- Ongoing monitoring where appropriate
For many people, these measures can significantly reduce the risk of progression to type 2 diabetes. Diabetes South Africa
Healthy Lifestyle Changes That Support Blood Sugar Control
Small, sustainable changes often have the greatest long-term impact.
Your GP may discuss:
Healthy Eating
Choosing a balanced diet rich in vegetables, fruit, whole grains, lean protein and healthy fats while limiting highly processed foods and sugary drinks.
Regular Exercise
Aim for regular physical activity that suits your age, fitness level and overall health.
Maintaining a Healthy Weight
Even modest weight loss can improve blood sugar regulation for many people.
Regular Health Assessments
Routine GP visits allow ongoing monitoring of blood pressure, cholesterol, weight and blood glucose, helping to identify changes early.
When Should You See Your GP?
Arrange a consultation if you:
- Have one or more diabetes risk factors
- Have previously been told your blood sugar is borderline
- Have a strong family history of diabetes
- Are concerned about your long-term health
- Would like a preventative health assessment
Early assessment can help identify risk factors and guide appropriate screening.

Can prediabetes be reversed?
Many people can improve their blood sugar levels through healthy lifestyle changes, although outcomes vary from person to person. Your GP can recommend the most appropriate management plan. Diabetes South Africa
Should everyone be screened for prediabetes?
Screening is generally recommended for adults with risk factors or from around age 45, depending on individual circumstances and South African guidance. Knowledge Hub
Does prediabetes always cause symptoms?
No. Most people with prediabetes have no symptoms, which is why routine screening can be important for those at increased risk. Diabetes South Africa
What tests are used to diagnose prediabetes?
