What is Diabetes?
Diabetes is a condition where the body is unable to properly regulate blood sugar (glucose) levels.
✔ Affects insulin production or usage
✔ Leads to high blood sugar levels
✔ Can damage organs like the heart, kidneys, nerves, and eyes
If left untreated, it may lead to serious long-term health issues.

Recognizing early symptoms can help prevent complications. If you notice any of these signs, it’s important to get tested:

Don’t ignore these signs—early testing can make a big difference.

Diabetes is commonly diagnosed using the Fasting Blood Sugar (FBS) test, Postprandial Blood Sugar (PPBS) test, HbA1c (Glycated Hemoglobin) test, Random Blood Sugar (RBS) test, and the Oral Glucose Tolerance Test (OGTT). Your doctor may recommend one or more of these tests based on your symptoms and medical history.
The HbA1c test measures your average blood sugar levels over the past two to three months. It does not require fasting and is one of the most reliable tests for diagnosing diabetes, identifying prediabetes, and monitoring long-term blood sugar control.
Regular diabetes screening is recommended for people over the age of 35, those who are overweight or obese, have a family history of diabetes, high blood pressure, a sedentary lifestyle, or symptoms such as excessive thirst, frequent urination, unexplained weight loss, or persistent fatigue.
Early diagnosis allows timely treatment and lifestyle changes that can help control blood sugar levels, prevent complications affecting the heart, kidneys, eyes, and nerves, and improve overall quality of life.
It depends on the test. The Fasting Blood Sugar (FBS) test requires fasting for 8–10 hours, while the HbA1c and Random Blood Sugar (RBS) tests do not require fasting. Your healthcare provider or diagnostic center will advise you on any preparation needed before your test.
