Diabetes Symptoms: Recognizing the Warning Signs

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. Symptoms vary by type (type 1, type 2, gestational) and disease stage. Early recognition enables timely intervention.

Classic Symptoms (The "Three Ps")

• Polyuria: Frequent urination, especially nocturia.
• Polydipsia: Excessive thirst and fluid intake.
• Polyphagia: Increased hunger despite adequate caloric intake.

Additional Common Symptoms

• Unexplained weight loss (especially type 1)
• Fatigue and weakness
• Blurred vision
• Slow-healing wounds or frequent infections
• Tingling/numbness in hands or feet (neuropathy)
• Recurrent yeast infections
• Dry, itchy skin
• Acanthosis nigricans (dark, velvety skin patches)

Type-Specific Presentations

Type 1: Often abrupt onset with weight loss, ketoacidosis risk.
Type 2: Gradual onset; may be asymptomatic initially.
Gestational: Typically screened at 24–28 weeks; may present with excessive weight gain.

When to Seek Care

Consult a healthcare provider if you experience multiple symptoms, have risk factors (obesity, family history, sedentary lifestyle), or belong to a high-risk ethnic group. Early diagnosis prevents complications.
