Diabetes - Symptoms & Diagnosis

Recognizing the symptoms of diabetes early is crucial for timely intervention and avoiding serious complications. Whether you’re at risk or already experiencing unusual signs, understanding how diabetes manifests and how it’s diagnosed can empower you to take control of your health.

Common Symptoms of Diabetes

Diabetes symptoms can be subtle at first, especially in type 2 diabetes. However, early warning signs often include:

  • Frequent urination (especially at night)
  • Excessive thirst and dry mouth
  • Unexplained weight loss
  • Increased hunger even after eating
  • Fatigue or lack of energy
  • Blurred vision
  • Slow-healing wounds or frequent infections
  • Tingling or numbness in hands and feet (a sign of nerve damage)

In type 1 diabetes, symptoms usually appear suddenly and can escalate quickly. In type 2 diabetes, they may develop gradually and go unnoticed for years.

How Diabetes Is Diagnosed

Diagnosing diabetes involves measuring blood glucose levels through simple lab tests. The most common diagnostic methods include:

  • Fasting Blood Sugar (FBS): Measures blood glucose after at least 8 hours of fasting. A level of 126 mg/dL or higher suggests diabetes.
  • A1C Test (Hemoglobin A1C): Reflects average blood sugar over the past 2–3 months. An A1C of 6.5% or higher indicates diabetes.
  • Oral Glucose Tolerance Test (OGTT): After fasting, you drink a sugary solution and your glucose is tested after 2 hours. A reading of 200 mg/dL or more confirms diabetes.
  • Random Blood Sugar Test: A reading of 200 mg/dL or more with symptoms is often enough for diagnosis.

For gestational diabetes, screening typically occurs during the second trimester using the glucose challenge test or OGTT.

When to See a Doctor

If you experience any diabetes symptoms or have risk factors—such as being overweight, having a family history, or leading a sedentary lifestyle—it’s essential to get tested. Early diagnosis allows for prompt treatment and helps prevent complications like nerve damage, kidney disease, and cardiovascular issues.
