My husband, my 9 year old son and my 5 year old daughter all use Medtronic insulin pumps. They all have Type 1 Diabetes. As far as I am concerned, there are NO cons to using pump therapy, only pros!
Pump therapy fine tunes insulin dosage so that your body is getting exactly the right amount of insulin. Your husband will see an improvement in his HbAlc, fewer lows and highs, etc.
Ask to talk to a diabetes nurse educator. He can actually trial a pump using saline, while taking his regular insulin shots. We love the Medtronic pumps but other options to look at are the Animas pump and the Omnipod. The Omnipod is controlled by remote.
The pump is costly, upfront. The infusion sets (tubing and catheter inserted into the skin), and reservoirs (connects to the infusion set and is filled with insulin) are also more expensive than syringes, but we will never, ever go back to shots. If you have any questions, feel free to private message me.
As always, I like to raise awareness for Type 1 diabetes to anyone reading and say that insulin is the only treatment for T1D. Exercise and nutrition are extremely beneficial but are not substitutes for insulin therapy.
Edit* I went to the American Diabetes Association website and wasn't impressed with their info. Juvenile Diabetes Research Foundation, or JDRF, has much better info, in my opinion.
