Conventional diabetes therapy primarily targets HbA1c using a standardized, stepwise approach, often neglecting individual clinical and diagnostic phenotypes. In this second part of our discussion, we present an alternative strategy. After phenotyping the patient, we initiate a targeted pharmacological combination therapy tailored to the individual’s underlying pathophysiology, alongside lifestyle modifications. Sulfonylureas are completely avoided in this approach. Instead, medications are selected based on their alignment with the patient’s phenotype and absence of contraindications. Early insulin therapy, for example, is particularly effective in patients with β-cell-dysfunction-driven diabetes, whereas GLP-1-supported weight reduction and glitazone therapy are more suitable for insulin-resistance-driven diabetes. For monitoring and determining when temporary therapy intensification may be necessary, we rely on a combination of functional biomarkers (intact proinsulin, adiponectin, hsCRP, and leptin) and conventional clinical parameters (HbA1c, BMI, lipids, blood pressure). Using this personalized strategy, we have consistently achieved long-term glycemic control—often maintaining normal HbA1c levels for up to 15 years in our patients so far.
