Common symptoms

  • Increased thirst
  • Frequent urination
  • Unexplained weight change

Type 2 diabetes is the most prevention-responsive chronic disease in modern medicine. Early-stage cases respond remarkably well to structured lifestyle change, particularly when paired with CGM visibility.

Diagnosis

HbA1c ≥ 6.5%, or two fasting glucose readings ≥ 126 mg/dL, or a symptomatic random glucose ≥ 200 mg/dL.

Treatment overview

Most early-stage type 2 diabetes can be reversed with a structured 90-day intervention — nutrition, movement, sleep, CGM-guided feedback — before pharmacological therapy.

When to book

HbA1c between 5.7–6.4 (prediabetes), family history, or symptoms — book a 45-minute endocrinology consult.
