My aunt has diabetes and she has to carry insulin pens with her everywhere she went.  She needs to make sure that she can get the additional insulin when her sugar drops as quickly as possible.

Making sure that she has all of her diabetic supplies on her is important.  She has multiple insulin pens.  She keeps one pen in her car, and one in her purse, and one just about everywhere she is.  Making sure that pens were always easily accessible.

Having diabetes is not something that you want to mess with.  You need to be able to act quickly if your sugar drops.  That is why having insulin pens easily available will help you to keep your sugar where it needs to be.
