Can't Control Your Blood Sugar? 5 Common Mistakes You Might Be Making

Managing blood sugar levels can feel like a constant balancing act, especially if you're living with diabetes or prediabetes. Frustration can set in when, despite your best efforts, your numbers remain stubbornly high or low. Often, the culprit isn't a lack of effort, but rather unintentional mistakes in your routine. Let's dive into five common mistakes people make when trying to manage their blood sugar, and how to correct them.

1. Inconsistent Carbohydrate Counting and Timing

One of the biggest pitfalls in blood sugar control is inconsistent carbohydrate intake. Carbohydrates are the primary nutrient that raises blood glucose levels, and not all carbs are created equal. Failing to account for carbs accurately or spacing them unevenly throughout the day can lead to unwanted blood sugar spikes and dips.

  • The Problem: Eating large servings of carbohydrate-rich foods at once, or skipping meals altogether and then overeating later. Guessing at portion sizes instead of measuring.
  • The Solution:
    • Learn Carb Counting Basics: Consult with a registered dietitian or diabetes educator to learn the basics of carb counting. This involves estimating or measuring the grams of carbs in each meal and snack. Use apps like MyFitnessPal or Carb Manager for tracking.
    • Distribute Carbs Evenly: Aim for consistent carb intake at each meal and snack. This helps your body process glucose more steadily.
    • Choose Complex Carbs: Opt for complex carbohydrates like whole grains, legumes, and non-starchy vegetables over simple sugars and refined grains. These digest more slowly, resulting in a gradual rise in blood sugar.

2. Neglecting the Impact of Protein and Fat

While carbohydrates get much of the attention, protein and fat also play a significant role in blood sugar management. Protein can help stabilize blood sugar levels by slowing down glucose absorption, while fat can further delay digestion and prevent rapid spikes. However, excessive amounts of either can have negative consequences.

  • The Problem: Focusing solely on carbs and neglecting protein and fat. Consuming too much saturated or trans fats. Not pairing carbs with a protein and fat source.
  • The Solution:
    • Balanced Meals: Aim for a balance of carbohydrates, protein, and healthy fats at each meal.
    • Lean Protein Sources: Include sources of lean protein such as chicken, fish, tofu, beans, or lentils.
    • Healthy Fats: Incorporate healthy fats from sources like avocados, nuts, seeds, and olive oil. Avoid processed foods high in trans fats.

3. Ignoring the Power of Exercise

Regular physical activity is a cornerstone of effective blood sugar control. Exercise helps your body use insulin more efficiently and can lower blood glucose levels directly. However, not all exercise routines are created equal.

  • The Problem: Inconsistent exercise habits or focusing solely on cardio. Failing to monitor blood sugar before, during, and after exercise.
  • The Solution:
    • Regular Activity: Aim for at least 150 minutes of moderate-intensity aerobic exercise (such as brisk walking) per week, spread throughout the week.
    • Incorporate Resistance Training: Include strength training exercises at least two times per week to build muscle mass, which improves insulin sensitivity.
    • Monitor Blood Sugar Levels: Check your blood sugar before, during, and after exercise to understand how your body responds and adjust your routine or medication as needed. Talk to your doctor about pre- and post-exercise fueling recommendations.

4. Inadequate Hydration

Dehydration can significantly impact blood sugar. When you are dehydrated, your blood becomes more concentrated, which can lead to higher blood sugar readings. Staying properly hydrated is crucial for overall health and effective glucose control.

  • The Problem: Not drinking enough water throughout the day. Opting for sugary drinks instead of water.
  • The Solution:
    • Aim for Adequate Water Intake: The general recommendation is to drink at least eight glasses of water per day, but this can vary based on activity level, climate, and individual needs.
    • Carry a Water Bottle: Keep a water bottle with you and refill it throughout the day to encourage frequent sipping.
    • Choose Water Over Sugary Drinks: Replace sugary drinks like soda, juice, and sweetened tea with water, unsweetened herbal tea, or sparkling water.

5. Medication Non-Adherence and Lack of Communication with Healthcare Professionals

Medication adherence is critical for managing blood sugar levels, especially if you are prescribed insulin or oral medications. Skipping doses or not taking medications as directed can lead to unpredictable blood sugar fluctuations.

  • The Problem: Missing doses, forgetting to refill prescriptions, or stopping medication without consulting a doctor. Not communicating concerns or side effects to your healthcare team.
  • The Solution:
    • Take Medication as Prescribed: Set reminders or use a pill organizer to ensure you take your medication as directed.
    • Refill Prescriptions on Time: Ensure that you have a sufficient supply of your medication and refill prescriptions before they run out.
    • Communicate with Your Healthcare Team: Regularly communicate with your doctor, diabetes educator, or registered dietitian about any concerns, side effects, or challenges you're experiencing. They can adjust your medication, provide additional education, or offer support.
