As a chronic metabolic disease, diabetes has become an important problem threatening global health. According to statistics, the number of diabetes patients in China has exceeded 140 million, and the prevalence rate is increasing year by year. Scientific management of diabetes is not only to control blood sugar, but also to prevent complications and ensure the quality of life. This introduction will provide all-round guidance for patients with diabetes from the three core points of blood glucose monitoring, diet control and complication prevention.
1、 Blood glucose monitoring: master the "barometer" of disease changes
(I) Monitoring frequency and indicators
Blood glucose monitoring is the cornerstone of diabetes management. It is recommended to dynamically monitor blood glucose changes through the following three methods:
1. Self monitoring of blood glucose (SMBG): multiple daily measurements, with key time points being before meals, 2 hours after meals, and before bedtime. Insulin users need to increase the number of measurements.
2. Glycated hemoglobin (HbA1c): Reflects the average blood glucose level over 3 months, with an ideal value controlled below 7%. A range of 7% -8% is acceptable for those with good control.
3. Dynamic blood glucose monitoring (CGM): Real time tracking of blood glucose fluctuations, suitable for high-risk populations with severe blood glucose changes or frequent hypoglycemia.
（2） Monitoring Tools and Techniques
When choosing a blood collection pen, pay attention to adjusting the needle tip angle and use the "fist clench finger extension light poke" method to alleviate pain. When storing test strips, attention should be paid to moisture and light protection. Expired test strips can cause errors. It is worth noting that post exercise or emotional fluctuations may cause transient fluctuations in blood sugar levels, and a comprehensive evaluation of multi day data is needed instead of a single result.
2、 Dietary Control: Scientific Nutritional Strategy
(1) Precise Combination of Three Major Nutrients
1. Carbohydrates: Choose low glycemic index (GI) ingredients such as whole grains (oats, quinoa), beans, and fiber rich rhizomes. Each meal should not exceed 50% of the total calories in carbohydrates, and should be divided into three equal portions for consumption with meals.
2. Protein: The intake of high-quality protein should reach 1-1.2g/kg · d of body weight. It is recommended to consume skinless chicken breast, deep-sea fish, sugar free yogurt, etc. daily. Patients with kidney disease should adjust their protein intake according to medical advice.
3. Fat: Control the intake of saturated fatty acids, limit fried foods and trans fats. Flaxseed oil and deep-sea fish oil rich in omega-3 fatty acids can be chosen as options.
（2） Dining Techniques and Taboos
Adopt the "Eat Less, Eat More" method, dispersing calories into 5-6 meals. Chewing slowly can prolong satiety, and it is recommended to chew each bite more than 20 times. Be wary of the "invisible sugar" trap, be alert to the intake of sugary drinks, control the total amount of artificial sweeteners or sugar substitutes when choosing, and be alert to the possible metabolic interference of sugar substitutes.
Special groups need personalized programs: pregnant women with diabetes need to increase chromium, zinc and other trace elements; Individuals with high levels of physical activity need to supplement with branched chain amino acids.
3、 Complications prevention: multidimensional health protection
(1) cardiovascular system protection
strict control of blood pressure (<130/80mmHg) and low-density lipoprotein cholesterol (LDL-C<2.6mmol/L). Aspirin use should be evaluated for bleeding risk, and anticoagulation therapy should be initiated in patients with concomitant atrial fibrillation. Regular fundus examination (every six months to one year) and foot nerve assessment (monthly self-examination of the sole).
（2） Microvascular Disease Intervention
1. Retinopathy: Laser therapy is suitable for pre proliferative cases, and anti VEGF drugs can delay vision loss.
2. diabetes nephropathy: ACEI/ARB drugs can reduce urinary protein excretion rate. If the urinary albumin/creatinine ratio (UACR) exceeds 30mg/g, active intervention is required.
3. Neuropathy: α - lipoic acid injection combined with mecobalamin oral administration can alleviate limb numbness, and fumigation and washing of Chinese medicine combined with acupuncture and moxibustion has significant effect.
（3） Infection prevention and control
diabetes patients are more likely to be infected with streptococcus pneumoniae, candida and other pathogens. It is recommended to get vaccinated against influenza and pneumonia every year, keep your feet dry and clean to avoid fungal infections.
（4） Four Steps to Personalized Management
1. Dynamic Evaluation: Quarterly retesting of complication indicators to establish personalized blood glucose target curves.
2. Digital empowerment: intelligent blood glucose meter+APP records to form a data model, and it is recommended to use the International diabetes Center (IDC) to verify the algorithm.
3. Multidisciplinary cooperation: endocrine nutrition rehabilitation department jointly customizes the scheme, such as orthopedic consultation for patients with diabetes foot.
4. Continuing education: Participate in patient support groups to understand the impact of differences in insulin secretion timing on blood glucose.
The management of diabetes needs to practice the concept of "five carriages": education is the basis, diet is the key, exercise is the means, monitoring is the guarantee, and medicine is the weapon. Through precise blood glucose monitoring, scientific dietary combinations, and systematic preventive measures, patients can fully achieve a high-quality life with illness. Remember, the best glycemic control plan is always personalized, and patients should maintain close interaction with the medical team and find the most suitable management plan under the guidance of scientific data.
