Changing to a pump smoothed out my control because the basal matched my needs, which vary a lot over 24hrs, whereas no basal insulin could. I’ve now used a pump for almost 21 years. I’ve always used tubed pumps because I prefer them and find them more flexible. My current pump is a Dana i, but I’ve had a few different ones over the years.
The major pro of a pump is the ability to fine-tune your basal. This is by far the best thing IMO. Other pros are not having to inject, but that’s more for convenience (I can use my phone to bolus on my pump); being able to have more closely tailored bolus doses, eg 5.35 units and not having to round up or down.
The negatives are the increased ‘stuff’ you need (sets, cannulas, reservoirs, etc); the increased risk of DKA; and the increased risk of site infections, which can be very unpleasant.
My advice
@ChrisLG is to focus on what’s best for you as an individual. Find out exactly why the consultant thinks a pump will suit you (eg is it to do with absorption, extended boluses, etc etc) and think whether you’d like to have a pump. If you’re happy on MDI, you don’t have to. Each has pros and cons, and MDI is simpler. Then find out what pumps would be on offer to you and start researching them - very thoroughly! There is no ‘best’ pump, only the best pump
for you.
