AID Systems Guide — Omnipod 5
Omnipod 5
Omnipod 5 is a tubeless, highly automated AID system with the algorithm housed inside the Pod itself. Discreet, simple to set up and operate, and designed to require minimal day-to-day user input.

About this system
Omnipod 5 is sometimes described as the Iron Man of AID systems: sleek, powerful, and surprisingly simple to operate.
Want to listen to the podcast? Episode 5: Mastering Omnipod 5 – The Iron Man of AID explores the Omnipod 5’s SmartAdjust technology, how to set it up, common pitfalls to avoid, and how to optimise insulin dosing for meals and activity.
Key features of this system:
- Tubeless design that makes it discreet and easy to wear
- Highly automated, requiring little user input, and simple to set up and operate
- The algorithm is housed inside the Pod, allowing seamless automated adjustments without a phone connection
If you are on the Omnipod 5, this guide covers:
- How the algorithm works
- Starting settings
- Tips and practical approaches
- Preventing and managing hypos
- High-fat meals
- Exercise
How the algorithm works
Omnipod 5 has four components:
- The Omnipod 5 controller
- A Dexcom G6 or G7 compatible phone if using a Dexcom sensor
- If using FreeStyle Libre 2 Plus, no phone is needed for operation (though there are no followers with this configuration)
- The Omnipod Pod — the algorithm lives inside the Pod itself, with no tubing
Key principles of how the algorithm tends to behave:
- The algorithm works from an automatically calculated basal rate called the Adaptive Basal Rate
- Basal insulin increases when glucose is rising and is reduced or stopped when glucose is dropping, with updates every five minutes
Starting settings
SmartAdjust needs one basal rate and a 24-hour total basal amount to start. The first Pod runs at roughly half capacity; from the second Pod onwards, the algorithm runs at full strength.
Starting an AID system can be broken down into two phases:
Survive
Get safe, stable, and familiar with how the system responds. The first Pod is a learning period — expect the algorithm to become more effective from the second Pod onwards.
Thrive
Once you understand the patterns, explore optimisation — adjusting carbohydrate ratios and activity mode settings to improve time in range.

Tips and practical approaches
Strong time in range on Omnipod 5 tends to combine the algorithm with good underlying habits:
- Three balanced meals
- Accurate carbohydrate counting
- Bolus insulin 10–20 minutes before eating
- Being active for 10–15 minutes after eating
- Rotating Pod sites

Other practical points to be aware of:
- A compatible phone is needed to operate Dexcom G6 or G7 with Omnipod 5 — without the phone, there is no data and no operation
- The Pod holds up to 200 units of insulin, so it may not last the full three days if you use more than around 65 units per day
Preventing and managing hypos
The algorithm tends to prevent many overnight hypos, but hypos will still occur — particularly if bolus insulin is too high for a given situation or exercise is unplanned.
Hypo treatment amounts often need to be smaller than before AID, because the algorithm tends to have reduced or stopped insulin at least 30 minutes earlier.
It is also worth considering a pre-emptive response if glucose is 4.0–6.0 mmol/L (70–110 mg/dL) and trending down.
The hypo guide below is based on weight — example shown is for a 30 kg person, but weight can be adjusted. The Survive and Thrive Guide — Omnipod 5 generates a personalised chart once you enter your weight.
High-fat meals
From the Mealtime Insulin Guide, we know that high-fat meals with carbohydrates (pizza, takeaways) tend to need additional insulin due to delayed gastric emptying and insulin resistance.
In theory, entering 100% of the carbohydrates eaten allows SmartAdjust to respond to the delayed rise. In practice, a degree of individual trial and exploration is often needed.
A starting approach for high-fat meals
Some people find that entering 25–50% extra carbohydrate (“fake carbs”) around 90 minutes after eating helps counter the delayed rise and insulin resistance seen with high-fat meals. For example, if the meal contains 100 g carbohydrate: enter 100 g upfront, then add an additional 25–50 g around 90 minutes later.
Individual responses vary — your CGM data is the best guide to what works for you.
Exercise
There is a quick method and a more comprehensive planned method.
The quick method
Turn on Activity mode before starting exercise — ideally 90 minutes beforehand. Then take small carbohydrate top-ups every 20 minutes as needed.
Avoid large carbohydrate loads all at once — glucose may spike and the algorithm may increase insulin, raising hypo risk.
How many grams every 20 minutes? It depends on body weight. The example below is for a 50 kg person. The Survive and Thrive Guide — Omnipod 5 generates a personalised chart once you enter your weight.

The comprehensive planned method
To use this approach, work through the Exercise Guide to understand exercise types, bolus reductions, and how to adapt plans after trials.
The T25/T25 table below tends to make more sense once you have read the exercise guide. The AID and Exercise Consensus Guideline is also worth reading — the infographic under the T25/T25 grid is particularly useful.

Explore the algorithm
The AID System Explorer generates exploratory output ranges for Omnipod 5 based on your TDD, weight, and responsiveness level. The detailed explainer explains how Omnipod 5 uses shorter AIT and lower targets to lower IOB visibility — the same optimisation strategy as the 780G — and the trade-offs this creates during exercise.
Key principles to take away
- Omnipod 5 is tubeless and highly automated — the algorithm inside the Pod makes adjustments every five minutes without requiring a constant phone connection
- The first Pod is a learning period — expect stronger algorithm performance from the second Pod onwards
- Activity mode should ideally be started 90 minutes before exercise, not at the point of activity
- High-fat meals and exercise tend to require specific approaches — individual exploration is needed using CGM data as feedback
- Pod capacity matters for higher insulin users — plan Pod changes accordingly
