What Should My Blood Glucose Control Target Be?

Okay, this question really hits the nail on the head! Friends who've just been diagnosed or hit a plateau in managing their blood sugar often ponder this. Don't worry, let me share my understanding to help clarify things for you.

Blood Sugar Targets? It's All About "Tailoring"

Hey friend, first and foremost, here's the most important concept: Blood sugar control targets aren't a "one-size-fits-all" answer; they're more like "custom-tailored suits," needing adjustment based on your individual situation.

Those numbers you find online, like fasting blood sugar should be below 6.1 mmol/L or post-meal below 7.8 mmol/L, are standards for healthy people. For us "fellow diabetics," the targets are generally a bit more flexible, and the degree of flexibility varies from person to person.

Generally, the "Universal Targets" Doctors Refer To

Let's look at a "basic" target that most diabetics can use as a reference point and a goal to strive for:

• Fasting Blood Glucose (measured when you wake up, before eating or drinking): 4.4 - 7.0 mmol/L
• Postprandial (2-hour) Blood Glucose (measured 2 hours after the first bite of a meal): < 10.0 mmol/L
• Glycated Hemoglobin (HbA1c) (This is the most important one!): < 7.0%

A simple way to understand:

• Fasting and Postprandial Glucose: These are like your daily "pop quizzes," reflecting what you ate, whether you exercised, and if your medication is working.
• Glycated Hemoglobin (HbA1c): This one is powerful; it's like your "quarterly report." It reflects your average blood sugar level over the past 2-3 months. Doctors primarily use this indicator to judge how well your long-term blood sugar control is and whether treatment adjustments are needed. So, don't get discouraged by a single high reading or complacent by a single normal one. HbA1c is the real deal.

Why Are Targets "Individualized"?

This is the key! What your specific targets should be depends mainly on the following factors:

1. Your Age

   • Younger/Middle-aged Adults: Generally healthier with good heart, liver, and kidney function. Targets are usually stricter, aiming for HbA1c below 6.5% or even lower. This maximizes prevention of future complications. Think of it like driving a new car – you can push the performance.
   • Older Adults (e.g., 70s, 80s+): For seniors, preventing "hypoglycemia" (low blood sugar) is more critical than controlling "hyperglycemia" (high blood sugar)! A single severe low blood sugar episode can trigger a heart attack or stroke, which is very dangerous. Therefore, targets are much more relaxed, with HbA1c levels of 7.5% - 8.0% or even 8.5% often acceptable. Think of it like driving a classic car – safety first, slow and steady wins the race.

2. How Long You've Had Diabetes

   • Recently Diagnosed: Your pancreas might still retain some function. Strict control early on can give your beta cells a rest, potentially leading to a "honeymoon period" (where blood sugar stays good on its own).
   • Long History of Diabetes: If you've had it for many years, with declining overall bodily function, targets will be appropriately relaxed.

3. Presence of Other "Companion Conditions"

   • If you also have serious heart disease, kidney disease, or other chronic conditions, your doctor will likely relax your blood sugar targets. This avoids putting extra strain on other organs by chasing perfect blood sugar numbers.

4. Your Susceptibility to Hypoglycemia

   • Some people feel hypoglycemia symptoms strongly (palpitations, shakiness, sweating), while others feel little or nothing (called "hypoglycemia unawareness," which is more dangerous). If you fall into the latter category or experience frequent lows, your targets must be more relaxed.

The Most Important Rule: Talk to Your Doctor!

After all this, the ultimate "gold standard" is just one thing: The target your own doctor sets for you.

Don't overthink it yourself, and don't force someone else's standards onto yourself. Make sure to actively ask your doctor during your follow-up visits:

"Doctor, based on my current situation, what are the appropriate target ranges for my fasting, postprandial blood sugar, and HbA1c?"

Your doctor is your "navigator." They know the condition of "your body's vehicle" best. Tell them about your lifestyle, work situation, and any discomfort you experience. They will help you set a target that is most suitable, safest, and most achievable for you.

To summarize:

Managing diabetes is a marathon, not a sprint. First, understand the general targets. Then, based on your individual circumstances, work with your doctor to set a personalized goal that's "within reach with effort." After that, it's about mindful eating, staying active, taking medication correctly, monitoring regularly, and taking it one step at a time.

Steady as we go!
