Site Rotation
Setup — 1 of 7

How do you take your insulin?

Your rotation setup depends on your delivery method. This shapes everything that follows.

⚙️
Insulin Pump
I wear a pump that delivers continuous insulin through a cannula I change every 2–3 days.
🖊
Multiple Daily Injections (MDI)
I inject with a pen or syringe multiple times per day.

How do you want to rotate?

Pick the method you'll actually stick with. There is no single right answer.

🕐
Clock Method
Work around each zone like a clock face — 12, 3, 6, 9 — moving one position each time.
🔲
Grid Method
Divide each zone into a grid and work through it top to bottom, left to right.
📍
Track Only
I'll pick my own sites. Just show me where I've been and warn me if I repeat too soon.

Set up your abdomen zones

The abdomen is your most reliable site. Choose how precisely you want to track it.

◑
Left / Right (2 zones)
Simple. One zone per side.
⊞
4 Quadrants
Upper and lower on each side. More precision, still manageable.
⊟
6 Zones
Upper, middle, and lower on each side. Maximum precision.
Avoid 2" around navel
Best practice — absorption is less consistent near the navel.

Which other areas do you use?

Select all that apply. Only activated zones appear on your body map.

✓
Left thigh (outer/lateral)
Good absorption. Variable with leg exercise.
✓
Right thigh (outer/lateral)
Good absorption. Variable with leg exercise.
✓
Left upper arm (outer)
Good absorption. May need assistance.
✓
Right upper arm (outer)
Good absorption. May need assistance.
✓
Left glute / buttock
Slowest absorption. Consistent for some basal users.
✓
Right glute / buttock
Slowest absorption. Consistent for some basal users.

Any areas to avoid?

Tap any zone on the map to mark it off-limits. The app will never suggest it. Scar tissue, sensitivity, preference — your reasons are your own.

How long before reusing a site?

Clinical guidelines suggest 14 days. But your zones, body, and injection frequency are unique. Set what works for you.

Absorption by Zone

Insulin doesn't absorb the same way everywhere. Here's what the research says — and what matters for an active life.

1
Abdomen
Fastest, most consistent absorption. Best for mealtime bolus. Avoid the 2-inch area around the navel — absorption is less predictable there.
2
Upper Arm (outer)
Fast absorption. Good alternative to abdomen. Absorption can be variable if you've recently exercised that arm.
⚠️ Upper arm injections before a swim or upper-body workout may absorb faster than expected.
3
Thigh (outer/lateral)
Moderate absorption. More variable than abdomen or arm. Often slower, but exercise significantly speeds it up.
⚠️ Avoid thigh injections before cycling, running, or any sustained leg activity. Absorption can accelerate unpredictably.
4
Glute / Buttock
Slowest absorption, but highly consistent for some users — particularly for long-acting basal insulin. Requires flexibility or assistance to self-inject.

For Active Users

Exercise increases blood flow and speeds absorption in muscles and tissue near the active area. A thigh injection before a long ride can absorb significantly faster than expected. When in doubt, use the abdomen — it's the most stable across activity levels.

What Is Lipohypertrophy?

Lipohypertrophy is scar tissue that forms under the skin from repeated injections in the same spot. It looks and feels like a firm lump or thickened patch. Insulin absorbs poorly — and unpredictably — from these areas. Consistent rotation is the primary prevention strategy. It's estimated to affect 30–40% of insulin-dependent diabetics, often without them knowing it.
