Managing Type 2 Diabetes For Dummies (For Dummies

1. Understand the Basics: Diabetes, Glucose, and Insulin

Diabetes is a disorder in which the amount of glucose, also called sugar, is too high in the blood.

Glucose is energy. When you eat, your body breaks food down into glucose, which travels in your bloodstream to cells for energy. Insulin, a hormone made by beta cells in the pancreas, acts like a key, helping glucose move from your blood into your cells.

• Glucose is your body's main energy source.
• Insulin is essential for glucose uptake by cells.
• The pancreas produces insulin and glucagon.

Type 2 diabetes issues. In Type 2 diabetes, either the pancreas doesn't make enough insulin, or the body's cells become less sensitive to insulin (insulin resistance), or both. This causes glucose to build up in the blood, leading to high blood glucose. High blood glucose can cause short-term symptoms like thirst and fatigue, and long-term damage to blood vessels and nerves.

Other types exist. While Type 2 is most common (90-95% of cases), Type 1 diabetes (autoimmune, requires insulin) and gestational diabetes (during pregnancy) also occur. Prediabetes is a state where blood glucose is higher than normal but not yet diabetes, offering a critical window for lifestyle changes to prevent progression.

2. Build Your Essential Healthcare Team

Building a trusted group of physicians, nurses, and specialists is an important part of your diabetes care.

You lead the team. Your healthcare team helps you manage diabetes, but you are in charge of assembling them and ensuring communication. The core team often includes a diabetes care provider (primary care or endocrinologist) and a certified diabetes educator (CDE).

• Diabetes care provider: Manages overall health, prescribes medication.
• CDE: Provides education on daily management, lifestyle changes.

Add specialists as needed. Depending on your health and complications, you may need other experts. A dietitian helps with meal planning, an ophthalmologist/optometrist checks eyes, a podiatrist cares for feet, and a pharmacist advises on medications.

• Dietitian: Expert in food and nutrition, creates personalized meal plans.
• Ophthalmologist/Optometrist: Checks for eye damage (retinopathy, glaucoma, cataracts).
• Podiatrist: Specializes in foot care, crucial due to nerve/circulation issues.
• Pharmacist: Medication expert, advises on interactions and side effects.

Communicate effectively. Share information between team members and with you. Bring medication lists and blood glucose logs to appointments. Don't hesitate to ask questions about your goals, treatments, and any concerns you have.

3. Monitor Your Blood Glucose to Stay Informed

Checking your blood glucose is essential for managing diabetes.

Know your numbers. Checking blood glucose provides a snapshot of your level at a specific moment, helping you see how food, exercise, and medication affect you. This differs from the A1C test, which shows your average level over 2-3 months.

• A1C goal: Often less than 7% for many adults.
• Fasting BG goal: Often 80-130 mg/dL.
• Post-meal BG goal: Often less than 180 mg/dL (1-2 hours after starting meal).

How to check. Use a blood glucose meter, test strips, and a lancet to get a small blood sample, usually from your finger. The meter reads the glucose level. Continuous glucose monitors (CGMs) provide real-time, continuous readings and trend data.

• Standard meters: Provide single point-in-time readings.
• CGMs: Offer continuous monitoring and trend information.
• Accuracy matters: Ensure your meter and strips are accurate.

Track and use data. Record your readings (logbook, app, meter download) along with details like meals, exercise, and medication timing. Share this data with your healthcare provider to evaluate your management plan and make adjustments. Use the data yourself to learn how different factors impact your glucose levels.

4. Prevent Complications by Managing Risks

The great news is that you can take active steps to lower your blood glucose by eating wholesome foods, exercising, losing weight, and taking prescribed medications.

High BG causes damage. Chronically high blood glucose damages blood vessels and nerves throughout the body, leading to serious long-term complications. These affect various organ systems.

• Microvascular damage: Affects small vessels (eyes, kidneys, nerves).
• Macrovascular damage: Affects large vessels (heart, brain, legs).

Major complications include:

• Heart disease and stroke (leading causes of death in people with diabetes).
• Kidney disease (can lead to kidney failure requiring dialysis or transplant).
• Eye disease (diabetic retinopathy, can lead to blindness).
• Nerve damage (neuropathy, causing pain, numbness, or issues with digestion, etc.).
• Foot problems (due to nerve damage and poor circulation, can lead to amputation).
• Skin issues (more prone to infections).

Manage risks proactively. Keeping blood glucose, blood pressure, and cholesterol in target ranges is crucial. Lifestyle changes (healthy eating, exercise, weight loss, quitting smoking) and taking prescribed medications are key preventive measures. Be aware of signs of severe highs (DKA, HHS) and lows (hypoglycemia) and know how to treat them.

5. Embrace Healthy Eating as a Cornerstone

Learning about wholesome, nutritious foods and how to incorporate them into meals is a critical part of managing your diabetes.

No "diabetes diet". Healthy eating for diabetes is simply healthy eating for everyone. Focus on a variety of nutrient-rich foods low in saturated fats, added sugars, and refined grains. A dietitian is your best resource for creating a personalized meal plan.

• Dietitians (RD/RDN): Provide medical nutrition therapy, help create personalized plans.
• Meal plan: A strategy for what and when you eat, tailored to your goals, lifestyle, and culture.

Focus on quality nutrients. Include plenty of nonstarchy vegetables, fruits in moderation, whole grains, lean proteins, and healthy fats. Limit unhealthy saturated and trans fats, added sugars (especially sugary drinks), and excess sodium.

• Carbohydrates: Main energy source (veggies, fruits, grains, beans). Affect BG most directly.
• Protein: Builds and repairs tissues (meat, fish, eggs, beans, nuts).
• Fats: Needed in small amounts (oils, nuts, seeds, avocado). Choose unsaturated fats.

Use food labels wisely. Food labels provide essential information on calories, serving size, total carbohydrates, added sugars, fats, and sodium. Use them to make informed choices and compare products. Pay attention to serving size and multiply nutrients if eating more than one serving.

6. Get Physically Active for Body and Mind

Exercise is one of the best things you can do for your body and mind.

Exercise lowers BG. Physical activity helps muscles use glucose for energy and increases insulin sensitivity, directly lowering blood glucose levels and improving A1C. The effects can be immediate and long-lasting.

• Immediate effects: Lower BG during and after exercise (up to 24 hours).
• Long-term effects: Improved A1C, insulin sensitivity, blood lipids, blood pressure.

Beyond blood glucose. Exercise offers numerous benefits: weight management, improved cardiovascular health, stronger muscles and bones, better sleep, and enhanced mood (reducing stress, anxiety, and depression).

• Weight loss/maintenance: Burns calories, helps balance energy intake.
• Heart health: Lowers blood pressure and improves cholesterol.
• Mental health: Releases endorphins, reduces stress and improves mood.

Aim for consistency. The American Diabetes Association recommends most adults with Type 2 diabetes get at least 150 minutes of moderate-to-vigorous aerobic exercise per week, spread over at least 3 days. Also, include resistance exercise (strength training) 2-3 days per week and flexibility/balance exercises. Start small and gradually increase intensity and duration.

7. Manage Your Emotions and Seek Support

Your emotional well-being is integral to your health.

Diabetes is stressful. Living with a chronic condition like diabetes can bring feelings of anger, denial, fear, frustration, and stress. These are normal responses, but if persistent, they can negatively impact your self-care and health.

• Anger/Denial: Common initial reactions, can hinder proactive management.
• Stress: Can raise blood glucose and make healthy habits harder.
• Diabetes Distress/Burnout: Feeling overwhelmed by daily management demands.

Recognize clinical issues. People with diabetes are at higher risk for depression and anxiety disorders. Symptoms like persistent sadness, loss of interest, fatigue, or excessive worry warrant professional help.

• Depression: More common in people with diabetes, affects mood, energy, motivation.
• Anxiety: Can manifest as excessive worry or specific fears related to diabetes management.

Seek support and coping strategies. Talk about your feelings with your healthcare team, family, or friends. Consider joining a diabetes support group (in-person or online) to connect with others who understand. Mental health professionals (therapists, psychologists) can provide effective treatments like cognitive behavioral therapy. Practice self-compassion and mindfulness.

8. Navigate Life with Diabetes: Work, School, Travel, Driving

You have certain rights as a person with diabetes...

Workplace rights. People with diabetes are protected from discrimination by disability laws like the Americans with Disabilities Act (ADA). Employers cannot discriminate in hiring, firing, or promotions and must provide reasonable accommodations (e.g., breaks for checking BG/medication).

• Disclosure is personal: You generally don't have to tell your employer unless it impacts job function or safety.
• FMLA: May provide unpaid leave for your or a family member's serious health condition.

School rights (for children/teens). Children with diabetes have the right to care and safety at school. Laws like Section 504 and IDEA ensure they can participate fully and receive necessary support.

• DMMP: Doctor's plan detailing care needs at school.
• 504 Plan: Written accommodations to ensure safety and participation.

Travel prepared. Plan ahead for trips by talking to your doctor, packing extra supplies/medication, and knowing security rules. TSA allows necessary diabetes supplies and liquids beyond standard limits.

• Pack smart: Carry supplies in hand luggage, dispose of sharps safely.
• Be aware: Check BG more often if activity/schedule changes.

Driving safety. Most people with diabetes can drive, but complications like severe lows, vision problems, or neuropathy can pose risks. Be aware of low BG symptoms while driving and pull over if needed.

9. Debunk Common Diabetes Myths

Myths and misconceptions about diabetes are everywhere!

Myth: Sugar causes diabetes. Fact: Eating too much sugar alone doesn't cause diabetes, but it contributes to weight gain (a risk factor). Type 2 diabetes has multiple risk factors, including genetics, ethnicity, and age. Regularly drinking sugary drinks does increase risk.

Myth: People with diabetes can't eat sweets/chocolate. Fact: Occasional, small portions of sweets can fit into a healthy meal plan for people with diabetes, just like for anyone else. Focus on moderation and overall dietary balance.

Myth: People with diabetes should eat special diabetic foods. Fact: There are no unique "diabetic foods." Healthy eating for diabetes is the same as healthy eating for everyone – focusing on nutrient-rich foods low in unhealthy fats, added sugars, and excess sodium.

Myth: People with diabetes are more likely to get colds/flu. Fact: You are not more likely to catch colds or flu, but you are at higher risk for serious complications from the flu. Get an annual flu shot and practice good hygiene.

Myth: You've failed if you need insulin. Fact: Needing insulin is often a natural progression of Type 2 diabetes as beta cells decline over time. It is not a reflection of personal failure but a necessary step in managing a progressive disease.

Myth: Diabetes is not that serious. Fact: Diabetes is a serious chronic disease that can lead to severe complications (heart attack, stroke, kidney failure, blindness, amputation) if not managed. Proactive management is crucial to prevent these outcomes.

10. Address Gender-Specific Health Concerns

Women with diabetes can (and should) live vibrant, active lives.

Women's unique issues: Hormonal changes throughout a woman's life can impact blood glucose management. Pregnancy requires careful planning and strict BG control for the health of both mother and baby. Menopause can cause BG fluctuations and increase risk of yeast infections and sexual discomfort.

• Menstruation: BG can be erratic before/during periods.
• Pregnancy: Increased risk for mother (preeclampsia) and baby (macrosomia, birth defects) if BG uncontrolled. Gestational diabetes increases lifelong T2 risk.
• Menopause: Falling estrogen can increase insulin resistance, hot flashes may mimic lows.

Men's unique issues: Men with diabetes are at higher risk for specific sexual health problems.

• Erectile Dysfunction (ED): Common in men with diabetes due to nerve and blood vessel damage. Treatable with medication or other options.
• Low Testosterone: More common in men with diabetes, can affect libido, energy, and mood.

Heart health focus. Both men and women with diabetes have increased cardiovascular risk, but women with diabetes have a particularly high risk of heart disease and stroke compared to men with diabetes. Managing BG, BP, cholesterol, weight, and quitting smoking are vital for both sexes. Discuss sexual health concerns with your provider; effective treatments are available.
