Why Early Detection Matters

Diabetes affects how the body uses blood sugar. Catching it early can reduce complications involving the heart, kidneys, nerves, eyes, and feet.


Common Early Symptoms

  • Unusual thirst (polydipsia)
  • Frequent urination
  • Unexplained weight loss
  • Increased hunger
  • Fatigue
  • Blurred vision
  • Slow-healing cuts or infections
  • Tingling in hands or feet

Type 1 vs Type 2 Patterns

Type 1 often starts faster and may include rapid weight loss and severe fatigue.

Type 2 may cause mild symptoms for years, which makes screening important even when you feel fine.


Risk Factors

  • Family history of diabetes
  • Overweight or obesity
  • Sedentary lifestyle
  • High blood pressure or abnormal cholesterol
  • History of gestational diabetes
  • Polycystic ovary syndrome (PCOS)

When to See a Doctor

Book an appointment if you notice multiple symptoms together, or if you have risk factors and have not been screened recently. Simple blood tests such as fasting glucose or HbA1c can help.
