I have experienced insulin leaking out around the cannula.
This is basically caused by cannula movement in the skin which allows insulin to leak out.
In my experiences this is either caused by my bad insertion techniques, hitting the pod or putting an unusual amount of pressure on the pod - (usually on a doorway or maybe by carrying one of my kids, or doing sports), or sometimes because the batch of pods I have as poor adhesive.
Large boluses (like 10 units for me) can also cause this problem so I tend to avoid large boluses.
Leaks like this are basically eliminated for me by making sure the pod sticks to the skin very well and does not get hit.
So my technique for applying:
- Wash the site and because I am a man shave any stray hairs off.
- Clean thoroughly with alcohol swabs
- Wait for the alcohol to dry
- Apply pod to skid and make sure you get a good stick
- When you are ready to hit the “start button” - pinch up on the skin around where the cannula will insert with two fingers and press down on the end of the pod with the cannula.
The pressing down, makes sure all the energy from the auto-inserter goes into sticking the cannula in the skin. I find where I have tough skin that if I do not press down on the pod I get kick-back and the cannula does not insert well, which eventually turns into a leak at the site.
If you are pitching a baseball or bowling a cricket ball, my tip is to just avoid the pitching/bowling arm as the forces on he pod will cause cannula.
And one more thing, I have encountered a couple batches of pods that just did not have great adhesive. Omnipod took them back quite happily and replaced them all. This is very rare, but it is a possibility to explore if you find that all the problems start with a new pod of pods.
If you still have adhesion problems, SkinTac is another good option. I use this only when I know I will be sweating a lot when I am wearing a pod. It helps keep the pod on the skin and stops the cannula from moving.
Anyways - that was a blast of ideas based on my assumptions about your problem
Maybe you could let us know a little more about your problem.
Where is it leaking?
Does this happen right away or on day 2 or 3 of pod wear?
