Self-Care of Diabetes Mellitus
Self-care in diabetes is not a single action but a daily, ongoing commitment. Patients must substitute their own judgment for many functions that a healthy pancreas performs automatically - from meal planning to insulin dosing. As the Textbook of Family Medicine puts it: "Patients have to substitute their brain for their pancreas to control their glycemia."
Below is a structured overview of all key self-care domains, drawn from current textbook evidence.
1. Diabetes Self-Management Education and Support (DSMES)
The foundation of all self-care is structured education. DSMES improves the patient's knowledge, skills, and emotional well-being. According to Harrison's Principles of Internal Medicine (22nd ed.), education must occur:
- At the time of diagnosis
- Annually thereafter
- When glycemic goals are not being met
- During major life transitions
More frequent contact with the diabetes care team - by phone, video, or in person - has been shown to improve glycemic control. Key topics include: glucose monitoring technique, insulin administration, hypoglycemia prevention, foot/skin care, sick-day management, and exercise guidelines.
2. Blood Glucose Monitoring
Continuous Glucose Monitoring (CGM) or Fingerstick (SMBG)
- CGM is now preferred when accessible; it provides real-time trends and reduces hypoglycemia risk.
- Fingerstick glucose monitoring remains valid for many patients.
- The target range for self-monitored glucose in most patients is 90-130 mg/dL (fasting/preprandial).
- HbA1c should be tested 2-4 times per year - at least twice yearly for well-controlled patients, quarterly when targets are not met.
HbA1c targets (individualized):
- General target: <7% for most non-pregnant adults
- Stricter (<6.5%) may be considered in younger patients with short disease duration and no CVD risk
- More lenient (<8%) is appropriate in elderly, those with hypoglycemia unawareness, or limited life expectancy
Urine or blood ketone monitoring is especially important for Type 1 DM patients during illness.
3. Medical Nutrition Therapy (MNT)
MNT is the ADA's term for optimal coordination of caloric intake with medications, insulin, and exercise. Key principles:
| Aspect | Recommendation |
|---|---|
| Calories | Individualized; modest weight reduction of 5-10% body weight improves insulin resistance in T2DM |
| Carbohydrates | Consistent carbohydrate counting; quality matters (whole grains, legumes, vegetables over refined carbs) |
| Fats | Limit saturated and trans fats; favor monounsaturated fats (olive oil, nuts) |
| Protein | Adequate intake; avoid high protein if chronic kidney disease is present |
| Sodium | <2,300 mg/day, especially with hypertension |
| Alcohol | Moderate if at all; never on an empty stomach (risk of hypoglycemia) |
| Meal timing | Regular, consistent timing - especially important for patients on insulin or sulfonylureas |
No single dietary pattern fits all patients. Mediterranean, low-carbohydrate, DASH, and plant-based diets have all shown benefit. The emphasis is on whole foods and avoidance of ultra-processed foods.
4. Physical Activity and Exercise
Regular physical activity is one of the most powerful self-care tools. Benefits include improved insulin sensitivity, weight management, cardiovascular risk reduction, and improved mental health.
Recommendations:
- Aerobic exercise: At least 150 minutes/week of moderate-intensity activity (brisk walking, cycling, swimming) - or 75 min/week of vigorous activity
- Resistance training: At least 2-3 sessions/week (weight training, resistance bands) to improve glucose uptake in muscle
- Reduce sedentary time: Break prolonged sitting every 30 minutes
- Type 1 DM: Requires extra attention to glucose levels before, during, and after exercise; may need carbohydrate supplementation or insulin dose adjustment
Key self-care actions around exercise:
- Check blood glucose before exercise (should be >100 mg/dL to start)
- Carry fast-acting carbohydrates (glucose tablets, juice) in case of hypoglycemia
- Stay hydrated
- Inspect feet before and after exercise
5. Foot Care
Diabetic foot complications are a leading cause of hospitalization and amputation. Daily foot inspection is a cornerstone of self-care.
Daily foot self-care:
- Inspect feet every day (use a mirror for soles; ask a family member if vision is impaired)
- Wash feet in lukewarm (not hot) water; dry thoroughly between toes
- Apply moisturizer to prevent cracking - but NOT between the toes
- Trim toenails straight across; avoid cutting corners
- Wear well-fitting, protective footwear at all times - never go barefoot, even indoors
- Avoid heating pads, hot water bottles, or soaking feet (neuropathy reduces pain sensation)
Report to your provider immediately:
- Any cut, blister, ulcer, redness, swelling, or infection
- Numbness, tingling, or burning pain in feet/legs
The provider should inspect feet 1-2 times per year; patients must do so daily (Harrison's, Table 416-1).
6. Skin Care
- Keep skin clean and moisturized to prevent infections
- Treat minor cuts and bruises promptly
- Avoid hot baths/showers that can dry the skin
- Watch for signs of skin infection (redness, warmth, pus) - people with diabetes are more susceptible
7. Sick-Day Management
Illness raises blood glucose due to stress hormones. Key principles:
- Never stop insulin during illness (even if eating less) - consult the care team about dose adjustment
- Monitor blood glucose more frequently (every 2-4 hours)
- Check ketones if glucose >240 mg/dL (especially Type 1)
- Maintain fluid intake to prevent dehydration
- If unable to eat, replace meals with carbohydrate-containing fluids (juice, broth, crackers)
- Contact healthcare provider if: glucose persistently >300 mg/dL, moderate/large ketones, vomiting/diarrhea lasting >6 hours, or fever
8. Medication Adherence
Taking medications correctly is a critical self-care behavior:
- Take medications at the same time each day
- Know how each medication works and what to do if a dose is missed
- Understand signs of hypoglycemia and how to treat it
- For insulin users: proper injection technique, site rotation, storage of insulin
- Never adjust doses without guidance - but learn how to self-titrate basal insulin if instructed
9. Hypoglycemia Recognition and Treatment
Every person with diabetes on insulin or a sulfonylurea must know this:
Symptoms: shakiness, sweating, confusion, rapid heartbeat, hunger, dizziness (typically at glucose <70 mg/dL)
Treatment - the "15-15 Rule":
- Take 15 grams of fast-acting carbohydrate (4 oz juice, 4 glucose tablets, regular soda)
- Wait 15 minutes
- Re-check glucose
- If still low, repeat
- Once normalized, eat a small snack to stabilize
Severe hypoglycemia (unconscious, unable to swallow): Glucagon injection or nasal powder - family/caregivers should know how to use it.
10. Psychosocial Self-Care
Diabetes distress affects up to 40% of people with diabetes and leads to burnout and worsening control. Important self-care actions:
- Recognize that emotional well-being is part of diabetes care
- Communicate distress, anxiety, or depression to your care team
- Seek structured support (diabetes support groups, therapy, peer mentorship)
- Screening for depression and anxiety should occur at every visit (Harrison's, Table 416-1)
11. Preventive Health Monitoring (Self & Clinic)
| Check | Frequency |
|---|---|
| Blood glucose (home) | Daily or per device |
| HbA1c | Every 3-6 months |
| Blood pressure | Every visit |
| Lipids | 1-2 times/year |
| Eye exam | Annually (or every 2 years if stable) |
| Foot exam (provider) | 1-2 times/year |
| Kidney function (urine albumin, eGFR) | Annually |
| Dental exam | Twice yearly |
| Immunizations | Influenza (annual), pneumococcal, hepatitis B, COVID-19 |
| Liver disease screen | If risk factors present (T2DM/prediabetes) |
12. Smoking and Alcohol
- Smoking cessation is essential - smoking dramatically accelerates cardiovascular and microvascular disease in diabetes
- Alcohol should be limited; always consume with food to avoid hypoglycemia; no more than 1 drink/day for women, 2/day for men

- Healthy eating
- Being active
- Monitoring blood glucose
- Taking medications
- Problem-solving (handling hypoglycemia, sick days)
- Reducing risk (foot care, eye exams, immunizations)
- Healthy coping
- Technology use (CGM, insulin pumps, apps)

Preventing of diabetes mellitus
The prevention of diabetes mellitus - particularly Type 2 DM - centers on lifestyle modification (diet, exercise, weight loss) for high-risk individuals with prediabetes or metabolic syndrome. Type 1 DM prevention remains largely experimental. Pharmacologic prevention (metformin) is an adjunct for very high-risk individuals.
