Guidelines for Type 2 Diabetes Treatment Treatment for ALL Diabetics and Impaired Glucose Tolerance Step 1: Education Nutritional counseling Weight loss if obese Regular exercise Daily self- foot exam Low dose ASA Folate ARB or ACEI for HTN or if urine is positive for microalbumin (or increase in urine albumin/creatinine) Statin for hyperlipidemia Minimize alcohol use Vaccinations Psychosocial screening Smoking cessation counseling Check HbA1C two times per year in those meeting glycemic goal Check HbA1C quarterly in patients whose therapy has changed and those not meeting glycemic goals HbA1C goal is < 7%, however, less stringent treatment goals of < 8% may be appropriate for older patients and individuals with comorbid condition Step 2, if HbA1C goals not achieved: Metformin preferred, with or without acarbose Pioglitazone (Actos) if metformin contraindicated Go to Step 3 if both metformin and pioglitazone are contraindicated May initiate QHS basal insulin for those with HbA1c > 8.5% Step 3, if HbA1C goals not achieved, add: 2 nd generation sulfonylurea or glinide or Add DPP-4 inhibitor Start or intensify insulin therapy if HbA1c goals not achieved with above steps Step 4, if HbA1C goals not achieved, add: TZD (if not already on and no contraindications) or 2nd generation sulfonylurea or DPP-4 inhibitor or GLP-1 agonist or Consider adding or adjusting insulin Reference: American Diabetes Association.
