Choosing a wear position that lasts
Site rotation, clothing and daily movement.

Where you wear an insulin pump's infusion set or pod affects how long it stays comfortable, how often it snags, and how well your skin holds up over months. This guide covers the practical side of choosing and rotating sites. Your pump's user guide lists the approved sites, and your care team can help if a site isn't working well.
Why rotation matters
Using the same small area again and again can cause lumpy or thickened tissue under the skin, called lipohypertrophy. Insulin may absorb less predictably from those spots. Moving each new site at least an inch or two from the last one, and rotating across several body areas, gives each spot time to recover.
A simple system helps. Some people picture a clock face around the navel area and move one "hour" each change. Others alternate sides each time. A note on your phone with the date and site works well too.
Spots that usually cause trouble
Pump user guides generally say to avoid scars, stretch marks, moles, bruises, the skin right around the navel, and places where the body bends a lot. From a practical point of view, also avoid waistbands, belt lines and bra lines, where clothing will rub and push on the set every day.
Match the site to your day
Think about what's coming in the next few days. If you're sleeping on your side, choose the side you don't lie on. Before a long run or a day of lifting, choose a spot that won't be squeezed by a backpack or hip belt. If you're starting a job that has you kneeling or bending, the back of the arm or upper buttock may last longer than the abdomen, if your system approves those sites.
Clothing and tubing
With a tubed pump, the site and where the pump rides should work together. A site on the abdomen with the pump on a belt clip keeps tubing short and out of the way. A site on the hip with the pump in a thigh pocket may need longer tubing. Our tubed-versus-tubeless guide covers clips, belts and tubing lengths.
When a site seems off
Redness, pain, swelling, warmth or a lump at a site, or highs that don't come down after a new site, are reasons to change the site and contact your care team. Some pump makers also give specific instructions for unexplained highs. Follow those, not this guide.
