Key Points at a Glance
Type 2 diabetes is the most common type of diabetes, and its management requires comprehensive consideration of blood sugar control, cardiovascular protection, complication prevention, and quality of life. This guide, based on research from experts like Claire J. Stocker, provides systematic methodology for type 2 diabetes treatment.
Modern type 2 diabetes management emphasizes individualized treatment, requiring treatment plans based on patient factors such as age, disease duration, comorbidities, and preferences. Treatment goals are not only blood sugar control but also improving overall health outcomes.
Diagnosis and Assessment
Diagnostic Criteria
According to ADA standards, type 2 diabetes can be diagnosed under the following conditions:
- Fasting blood sugar ≥126 mg/dL (7.0 mmol/L)
- 2-hour blood sugar ≥200 mg/dL during oral glucose tolerance test
- HbA1c ≥6.5%
- Random blood sugar ≥200 mg/dL with hyperglycemia symptoms
Initial Assessment
After diagnosis, a comprehensive initial assessment is needed:
- Detailed medical history and physical examination
- Blood sugar control indicators (HbA1c, fasting blood sugar, post-meal blood sugar)
- Comorbidity assessment (cardiovascular disease, kidney disease, retinopathy, neuropathy)
- Comorbid conditions and medication history
- Lifestyle assessment
Treatment Methods
Lifestyle Intervention
Dietary adjustment: Adopt healthy eating patterns such as Mediterranean diet, DASH diet, or low-carbohydrate diet. Control total calories and maintain nutritional balance.
Exercise prescription: At least 150 minutes of moderate-intensity aerobic exercise per week, combined with 2-3 times weekly strength training. Exercise improves insulin sensitivity.
Weight management: For overweight or obese patients, losing 5%-10% of body weight can significantly improve blood sugar control.
Oral Hypoglycemic Drugs
First-line drugs: Metformin is the first choice for most type 2 diabetes patients.
Second-line drug selection (based on patient conditions):
- High cardiovascular risk: SGLT-2 inhibitors or GLP-1 receptor agonists
- Heart failure: SGLT-2 inhibitors
- Chronic kidney disease: SGLT-2 inhibitors or GLP-1 receptor agonists
- Weight loss needed: GLP-1 receptor agonists or SGLT-2 inhibitors
Insulin Therapy
When oral medications cannot control blood sugar, insulin therapy needs to be initiated:
- Basal insulin (long-acting insulin) as starting point
- Add mealtime insulin as needed
- Insulin pump therapy is another option
Monitoring and Follow-up
Blood Sugar Monitoring
- HbA1c: Test every 3 months
- Self-monitoring of blood glucose: Individualized based on treatment regimen
- Continuous glucose monitoring (CGM): For patients using insulin or with frequent hypoglycemia
Complication Screening
- Retinopathy: Annual eye examination
- Nephropathy: Annual urine albumin/creatinine ratio test
- Neuropathy: Annual foot examination
- Cardiovascular risk: Regular blood pressure and lipid monitoring
Frequently Asked Questions
Q1: Do type 2 diabetes patients need medication for life?
Most type 2 diabetes patients need long-term use of hypoglycemic drugs to control blood sugar. However, through active lifestyle intervention, some patients can reduce medication doses or temporarily not need medication.
Q2: Can type 2 diabetes be cured by surgery?
For severely obese (BMI>35) type 2 diabetes patients, metabolic surgery (such as gastric bypass) may significantly improve or even reverse diabetes. But surgery has risks and requires careful evaluation.
