Understanding Your Diabetic Screen
Diabetes is one of the most common chronic medical conditions worldwide, and many people may not realise they have it until complications develop. In my practice, I encourage regular diabetic screening because early detection allows us to begin treatment and lifestyle modifications before long-term complications occur.
A diabetic screen is an important part of preventive healthcare, particularly for individuals with risk factors.
What Is a Diabetic Screen?
A diabetic screen is a series of assessments used to evaluate your blood sugar levels and identify diabetes or prediabetes.
Depending on your clinical needs, your doctor may recommend:
- Fasting Blood Glucose
- HbA1c (Glycated Haemoglobin)
- Urine glucose and protein tests
- Blood pressure assessment
- Lipid Profile
- Kidney function tests
Together, these investigations provide a comprehensive picture of your metabolic health.
Who Should Have a Diabetic Screen?
Your doctor may recommend screening if you:
- Are aged 35 years or older
- Are overweight or obese
- Have a family history of diabetes
- Have high blood pressure
- Have high cholesterol
- Have a history of gestational diabetes
- Have polycystic ovary syndrome (PCOS)
- Lead a sedentary lifestyle
- Are attending a routine health screening
Common Symptoms of Diabetes
Some people experience no symptoms at all. Others may notice:
- Increased thirst
- Frequent urination
- Increased hunger
- Unexplained weight loss
- Fatigue
- Blurred vision
- Slow wound healing
- Frequent infections
These symptoms should be assessed promptly by a healthcare professional.
Understanding the Tests
Fasting Blood Glucose
Measures your blood sugar after fasting and helps identify diabetes or prediabetes.
HbA1c
This test reflects your average blood glucose over the previous two to three months and is commonly used to diagnose and monitor diabetes.
Kidney and Urine Tests
These help detect early signs of kidney damage, which can occur as a complication of diabetes.
Lipid Profile
People with diabetes have an increased risk of cardiovascular disease, making cholesterol assessment an important part of diabetes care.
Why Is Early Detection Important?
Diabetes can affect many organs, including the heart, kidneys, eyes and nerves. Early diagnosis allows treatment to begin sooner, helping reduce the risk of long-term complications through lifestyle modification and, when appropriate, medication.
When Should You See a Doctor?
Arrange a medical review if you:
- Experience symptoms of diabetes
- Have a family history of diabetes
- Have high blood pressure or high cholesterol
- Are overweight
- Have previously had abnormal blood sugar results
- Are due for a routine health screening
Doctor's Insight
In my practice, I remind patients that diabetes often develops gradually and may not cause noticeable symptoms in its early stages. Regular diabetic screening allows us to detect problems early, provide appropriate treatment and help patients protect their long-term health through preventive care.
