10 Type 1 Diabetes Mistakes I Made So You Don’t Have To

Living with Type 1 diabetes is one long learning curve.

I’ve been managing it for years and I still make mistakes.

The good news is that many of the biggest lessons come from the mistakes we make along the way.

Looking back, there are several things I wish I’d understood much earlier. Some affected my blood sugars. Some affected my stress levels. And some simply made diabetes harder than it needed to be.

Here are ten mistakes I made and what I learned from them.

1. Using The Same Injection Sites Repeatedly

This is probably the biggest mistake I made.

For years, I heavily relied on the same areas of my stomach.

Eventually, I developed lumps on both sides of my lower abdomen, and my insulin became much less predictable.

Once I started rotating sites properly, things improved significantly.

2. Reusing Insulin Needles Too Often

I’ll be honest.

I’ve reused needles many times.

Usually because I was busy or simply couldn’t be bothered changing them.

Over time, I realised that fresh needles and better injection habits helped improve consistency.

3. Trying To Correct Every High Immediately

Whenever I saw a high blood sugar, I’d often panic and take extra insulin too quickly.

This usually led to:

overcorrections
unexpected lows
frustration

I’ve learned that patience is often more useful than panic.

4. Treating Every Low Like An Emergency Buffet

Anyone with Type 1 diabetes has probably done this.

Blood sugar crashes to 3.4 mmol/L.

Ten minutes later, you’ve eaten:

glucose tablets
biscuits
chocolate
half the kitchen cupboard

Then comes the rebound high.

5. Chasing Perfect Blood Sugars

I used to think every reading had to be perfect.

The reality is that diabetes doesn’t work like that.

Now I focus more on trends and time in range rather than individual numbers.

6. Ignoring The Impact Of Stress

For years, I underestimated stress.

Looking back, many of my “unexplained highs” weren’t unexplained at all. A few months ago, I meet some new T1D friends and due to nerves, my levels was high even though I didn’t eat or drink anything.

7. Not Prioritising Sleep

Sleep affects:

insulin sensitivity
appetite
stress
decision-making

Yet it’s one of the things I paid the least attention to.

8. Comparing My Diabetes To Other People’s

Social media can sometimes make it look like everyone else has perfect blood sugars.

They don’t.

Everyone’s diabetes behaves differently.

Comparing yourself to others usually creates more stress than solutions.

9. Leaving The House Without Hypo Treatment

I’ve done this more than once.

It’s always fine until the one time it isn’t.

Now I try to keep something nearby at all times.

10. Thinking One Bad Day Means Failure

This may be the biggest lesson of all.

One bad day.

One bad sensor.

One difficult week.

None of these mean you’ve failed.

Type 1 diabetes is about managing thousands of decisions over a lifetime, not winning every single day.

Final Thoughts

If I could go back and tell my younger self one thing, it would be this:

Stop trying to be perfect.

The goal isn’t perfect diabetes management.

The goal is building habits that make diabetes feel a little easier to live with.
