Diabetes is one of the most common chronic diseases in Malaysia, yet many people do not realise they have it until complications develop. In its early stages, diabetes may cause few or no symptoms, making regular screening an important part of preventive healthcare.

A simple blood test can detect prediabetes or diabetes before serious health problems arise. But when should you start getting screened? The answer depends on your age, lifestyle, family history, and overall health.

Why Is Diabetes Screening Important?

Diabetes screening helps identify elevated blood sugar levels before they lead to complications. Early detection allows you to make lifestyle changes or start treatment promptly, reducing the risk of long-term damage.

Undiagnosed or poorly controlled diabetes can increase the risk of:

Heart disease and stroke
Kidney disease
Vision problems and diabetic eye disease
Nerve damage
Poor wound healing
Serious foot complications

Finding diabetes early gives you the best opportunity to protect your long-term health.

At What Age Should You Start Screening?

Many healthcare professionals recommend that adults begin routine diabetes screening from around 35 years of age, even if they feel well, especially if they have never been tested before.

However, you may benefit from earlier screening if you have additional risk factors or symptoms.

Who Should Get Screened Earlier?

You should consider diabetes screening regardless of age if you:

Have a parent or sibling with diabetes
Are overweight or obese
Have a large waist circumference or excess abdominal fat
Have high blood pressure
Have abnormal cholesterol or triglyceride levels
Live a physically inactive lifestyle
Have previously been diagnosed with prediabetes
Had diabetes during pregnancy (gestational diabetes)
Have a history of delivering a large baby
Have conditions associated with insulin resistance, such as polycystic ovary syndrome (PCOS)
Belong to an ethnic group with a higher risk of Type 2 diabetes
Experience symptoms suggestive of high blood sugar

If several of these risk factors apply to you, don't wait until you're older to get checked.

Signs That Should Prompt Immediate Screening

Even younger adults should arrange a diabetes test if they notice symptoms such as:

Frequent urination
Excessive thirst
Persistent fatigue
Blurred vision
Increased hunger
Unexplained weight loss
Slow-healing wounds
Frequent infections
Tingling or numbness in the hands or feet

Some people have no symptoms at all, which is why routine health screening remains valuable.

What Tests Are Used to Screen for Diabetes?

Several blood tests can help detect diabetes or prediabetes.

HbA1c Test

The HbA1c test measures your average blood sugar level over the previous two to three months. It does not usually require fasting and is commonly used for both screening and monitoring diabetes.

Fasting Blood Glucose

This test measures your blood sugar after an overnight fast and provides a snapshot of your glucose level at that time.

Oral Glucose Tolerance Test

This test measures how your body handles sugar after drinking a glucose solution. It may be recommended in selected situations, such as pregnancy or when other test results are inconclusive.

Your doctor will advise which test is most appropriate based on your medical history and risk factors.

How Often Should You Be Screened?

The ideal screening interval varies from person to person.

Average-risk adults: Every few years may be appropriate, depending on age and overall health.
People with prediabetes or multiple risk factors: More frequent monitoring may be recommended.
People with diabetes: Regular follow-up testing is important to assess blood sugar control and treatment effectiveness.

Can Lifestyle Changes Reduce Your Risk?

Yes. Healthy habits can significantly reduce the likelihood of developing Type 2 diabetes.

Simple steps include:

Staying physically active	Maintaining a healthy weight	Eating a balanced diet rich in vegetables, whole grains, and lean protein
Limiting sugary drinks and highly processed foods	Getting adequate sleep	Avoiding smoking
Managing stress	Drink adequate amount of water (1.5-2L/day)	Be sensible with alcohol

For people with prediabetes, these changes may help return blood sugar levels to the normal range.

Why Health Screening Matters Even If You Feel Fine

Many individuals with prediabetes or early diabetes feel completely well.

By the time symptoms become obvious, complications may already be developing. Routine health screening allows doctors to identify abnormal blood sugar levels early, giving you more options to prevent progression and protect your health.

Conclusion

There is no single age that applies to everyone, but diabetes screening should not be delayed if you have risk factors or symptoms.

Whether you're in your 20s with a strong family history or over 35 and due for a routine check-up, early testing can provide valuable information about your health and help prevent future complications.

A simple blood test today could make a significant difference to your long-term wellbeing.
