One of the most frustrating parts of Type 1 diabetes is feeling like you’re on a constant rollercoaster.
High.
Low.
High again.
Sometimes it can feel like you’re spending more time correcting blood sugars than actually living your life.
I’ve certainly had periods where my Libre graph looked more like a mountain range than a blood sugar chart.
While I still don’t get perfect readings every day, there are a few things that have helped make my blood sugars more predictable and reduced some of the extreme ups and downs.
I Stopped Chasing Perfect Numbers
One of the biggest mistakes I used to make was reacting emotionally to every reading.
If I saw a high number, I’d want to correct it immediately.
If I saw a low number, I’d sometimes over-treat it.
Both usually created another problem a few hours later.
Over time, I’ve learned that trends matter far more than individual readings.
One bad number doesn’t ruin a day.

I Started Rotating My Injection Sites Properly
This was probably one of the biggest improvements for me personally.
For years I heavily overused my stomach.
Eventually I developed lumps on both sides of my lower belly.
Sometimes insulin seemed delayed.
Sometimes it felt like it wasn’t working properly at all.
Once I became more consistent with rotating injection sites, I noticed my insulin seemed more predictable and effective.
Now I mainly rotate between different areas rather than repeatedly using the same spots.

I Became More Consistent With Meals
I’m not someone who follows a perfect diet.
But I have noticed that eating reasonably similar meals during the week makes blood sugar management easier.
When every meal is completely different, it becomes much harder to spot patterns.
Simple meals often lead to simpler diabetes management.

I Started Paying More Attention To Stress
For a long time I underestimated how much stress affected my blood sugars.
Sometimes my readings would be higher even when my food and insulin hadn’t changed.
Looking back, stress was often playing a role.
Work pressure.
Poor sleep.
General life stress.
All of these can affect blood sugar levels.

I Tried To Move More
You don’t need to become an athlete.
Even regular walking can make a difference.
Movement helps your muscles use glucose and can improve insulin sensitivity.
I’ve found that staying active generally helps make my blood sugars more predictable.

I Stopped Looking At One Reading In Isolation
This was another important lesson.
A blood sugar of 11 mmol/L doesn’t tell you much on its own.
Neither does a reading of 4 mmol/L.
The pattern is what matters.
Looking at several days of Libre data tells a much bigger story than focusing on a single number.
I Accepted That Some Days Are Just Different
This one took me the longest to learn.
Sometimes:
- stress is higher
- sleep is worse
- hormones are different
- activity levels change
And blood sugars respond accordingly.
Not every high reading means you’ve done something wrong.
Sometimes diabetes is simply being diabetes.
Products That Helped Me Stay Organised
These don’t magically improve blood sugars, but they can make daily management easier.
Keeping supplies in one place helps reduce stress.
Staying hydrated is a simple habit that’s easy to overlook.
Useful for protecting sensors during active days.
