A pump is a really big responsibility so you have to be willing to take that on. If the pump fails for some reason, you have no insulin reserves in your body because you are no longer using long-acting insulin, so your blood sugars can rise very quickly. Because of this, it is necessary to check your blood sugars more often to avoid dangerous highs. It's a trade-off: no shots, more blood tests. There is also a greater risk of infections with a pump, so it's also important to keep things sanitary when changing your pump site.
There are pros and cons to every method of therapy. Some prefer a stricter schedule as with MDI and like having their day planned out. Others like the flexibility of a pump and being able to change plans at the last minute.
I have used a pump for 10 years. I graduated college twice and while I work full-time, I have no regularity to the shifts I work. For me, a pump is better because I need flexibility as my days are always changing and meal times are different. I started a pump when I was in high school. I participated in a competitive dance group and we would travel long distances every weekend to compete. I needed the flexibility then because of the early mornings and late nights.
Before starting on a pump, you need to have a handle on how to treat your diabetes using MDIs. If your pump fails, is recalled, or stops working, you will need to go back to MDI until a replacement is shipped to you, so you need to be comfortable using them. There are LOTS of different pumps out there. I STRONGLY encourage you to take a very close look at all of them. When I was first searching for a pump, I was allowed to take one home for 3 days and test it out to see how I liked it. I would talk with your doctor and educators to see if they offer that for you. Each pump offers something different and unique. There will be certain features you like and certain ones you dislike. Pumps are also VERY expensive (about $5000 each before insurance), so don't take the decision lightly. It would be a terrible waste of money to purchase one and decide you don't like it.
