Management of Patients with Diabetes and Hypertension: Counseling and Medication Therapy
For patients with diabetes and hypertension, comprehensive management should include lifestyle modifications (DASH diet, sodium restriction, physical activity, weight management) alongside appropriate pharmacotherapy, with ACE inhibitors or ARBs as first-line agents, targeting blood pressure <130/80 mmHg. 1
Lifestyle Interventions
Dietary Recommendations
- Follow a DASH-style eating pattern with reduced sodium intake (<2,300 mg/day) and increased potassium intake 1, 2
- Increase consumption of fruits and vegetables (8-10 servings per day) and low-fat dairy products (2-3 servings per day) 1
- Reduce saturated fat, trans fat, and cholesterol intake 1
- Moderate alcohol consumption (no more than 2 drinks daily for men and 1 drink daily for women) 1
- For patients with elevated triglycerides (≥150 mg/dL) or low HDL cholesterol (<40 mg/dL for men, <50 mg/dL for women), intensify lifestyle therapy and optimize glycemic control 1
Physical Activity
- Recommend at least 150 minutes of moderate-intensity aerobic physical activity per week, distributed over at least 3 days 1
- Include muscle-strengthening activities 1, 3
- Reduce sedentary time throughout the day 1, 3
- For weight loss maintenance, consider increasing to 7 hours of moderate or vigorous aerobic activity per week 1
Weight Management
- Recommend weight loss if overweight or obese through caloric restriction 1
- Set realistic weight loss goals (5-10% of body weight) 1, 3
Medication Therapy Management
Blood Pressure Management
Pharmacologic therapy algorithm:
- First-line therapy: ACE inhibitor or ARB (especially important for patients with albuminuria or coronary artery disease) 1, 4
- Add-on therapy: Thiazide-like diuretic (preferably chlorthalidone or indapamide) or dihydropyridine calcium channel blocker 1
- For resistant hypertension: Consider adding a mineralocorticoid receptor antagonist 1
For patients with BP 130-139/80-89 mmHg: Start with lifestyle modifications for maximum 3 months; if target not achieved, initiate pharmacologic therapy 1, 2
For patients with BP ≥140/90 mmHg: Initiate both lifestyle and pharmacologic therapy immediately 1
For patients with BP ≥160/100 mmHg: Promptly initiate and titrate two drugs or a single-pill combination 1
Monitoring and Follow-up
- Monitor blood pressure at every routine diabetes visit 1
- For patients on ACE inhibitors, ARBs, or diuretics: Check serum creatinine/eGFR and potassium levels within first 3 months of therapy and at least annually thereafter 1
- Watch for potential adverse effects:
- Counsel patients about potential hypoglycemia when combining antihypertensive and antidiabetic medications 5
- Advise female patients of childbearing age about pregnancy risks with ACE inhibitors and ARBs 4, 5
Comprehensive Risk Management
- Assess and manage all cardiovascular risk factors, including lipids and smoking status 1, 6
- Consider aspirin therapy for secondary prevention in patients with established cardiovascular disease 1
- Recommend annual influenza vaccination 1
- Screen for and manage diabetes complications (retinopathy, nephropathy, neuropathy) 6, 7
- Emphasize the importance of medication adherence and regular follow-up 1, 6
Special Considerations
- In elderly patients, gradually lower blood pressure to avoid complications 1, 2
- For patients with diabetic nephropathy (albuminuria), ACE inhibitors or ARBs are strongly recommended to reduce progression of kidney disease 1, 2, 4
- Multiple-drug therapy is generally required to achieve blood pressure targets in most patients 1
- Avoid combining ACE inhibitors with ARBs due to increased risk of adverse effects without additional benefit 1
- Consider orthostatic blood pressure measurements when clinically indicated 1, 2
