You and your health care team will determine the insulin amount needed for each carbohydrate serving. The pump allows for a lot of meal flexibility. The basal insulin delivery helps keep you stable. Pump users adore their pumps and are extremely comfortable wearing them. If you cannot commit to testing your blood sugar frequently, then it is not for you.
Special clothing exists for pump users.
Nightgowns and shirts are available with specially made pump pockets. Some users place their pump inside their pillowcase. Others put it into a sock then pin it to pajamas or a sheet. Most find that it does not bother their sleep at all. Many pumps offer a remote control, so a bolus can be given without touching the pump.
