When you’re diagnosed with Type 1 diabetes, you’re told to rotate your injection sites.
Simple enough.
But after years of injections, it’s surprisingly easy to fall into the habit of using the same comfortable spots over and over again.
That’s exactly what I did.
Unfortunately, I paid the price with lumps that made my insulin far less predictable.
Why Rotation Matters
Repeated injections into the same area can lead to lipohypertrophy.
These are lumps that develop beneath the skin and can affect how insulin is absorbed.
For me, this meant insulin sometimes worked quickly, sometimes slowly and sometimes not how I expected at all.
Common Injection Areas
Most people use:
- Abdomen
- Thighs
- Buttocks
- Upper arms
Using different areas helps give your skin time to recover.
Signs You Should Rotate
You may notice:
- lumps
- hard patches
- tenderness
- unpredictable insulin absorption
If you recognise any of these, it could be worth discussing your injection technique with your diabetes care team.
My Experience
I used the same parts of my stomach for far too long because they were familiar and convenient.
Looking back, I wish I’d rotated much sooner.
Once I started using different areas consistently, my insulin absorption felt far more reliable.

Frequently Asked Questions
What happens if I keep injecting into the same place?

Can injection site lumps go away?
Some improve when the area is given time to recover, but it’s best to seek advice from your diabetes team if you’re concerned.
Should I rotate injection sites every day?

Final Thoughts
Looking after your injection sites is one of those small habits that doesn’t seem important until it becomes a problem.
For me, better rotation made one of the biggest differences to how predictable my insulin felt.
It’s a simple change that can pay off for years to come.
