How to Ignore Glucose

Ignoring glucose lets you temporarily hide or de-emphasize readings, so you can focus on the data that feels most useful when reviewing your trends.

What “Ignore glucose” is for

Ignoring glucose can be useful when readings don’t reflect your usual patterns.

For example:

• Volatile readings during a sensor warm-up or calibration period
• Spikes or drops related to external factors like a sauna, hot shower, cold plunge, or very hot bath
• Short-term changes from illness, medications, or unusual stress

When you ignore glucose for a time range, Levels visually de-emphasizes those readings so you can focus on the data that matters most.

How ignoring glucose works

You can ignore glucose for a specific date and time range.

When applied:

• Glucose in that range is visually de-emphasized on your chart
• The range appears anywhere ignored glucose is listed or summarized in the app
• You can keep using other features, like logging food, exercise, sleep, and notes

You can add new ignored ranges, review existing ones, or remove them later.

Method 1: Ignore glucose from a lifestyle log

Use this method when you are logging something that explains why glucose is temporarily unusual (for example, sauna, hot shower, cold plunge, illness, or stress).

1. Open the Levels app.
2. Tap the + button.
3. Tap Lifestyle.
4. Log a lifestyle event.
5. Tick the Ignore glucose box for that time range.
6. Optionally add a note.
7. Tap Save.

Glucose readings during that time will be treated as ignored.

Method 2: Ignore glucose from the glucose chart

Use this method when you see a specific period on your chart you want to ignore.

1. Open the Levels app.
2. Go to your glucose chart.
3. Tap the time on the chart where you want the ignored range to start.
4. Tap the small + button that appears.
5. Select Ignored glucose range.
6. Adjust the start and end times if needed.
7. Tick the Ignore glucose box.
8. Tap Save.

The selected portion of the chart will now appear as an ignored range.

Method 3: Use the Ignore glucose manager

Use this method when you want to review or manage all ignored ranges in one place.

1. Open the Levels app.
2. Go to your glucose chart.
3. Tap the three dots at the top of the chart.
4. Tap Ignore glucose.
5. To add a range, tap +, then set the start and end time and tick the Ignore glucose box.
6. To review or change an existing range, tap it in the list to edit or remove it.

Where ignored glucose shows up

Ignored ranges are visible in a few places:

• Ignore glucose screen: A list of all ignored glucose ranges, including start and end times
• Glucose chart: Ignored ranges are visually indicated on the graph
• Lifestyle logs: If you ignore glucose from a lifestyle log, that time range appears on the log’s timeline

Managing ignored glucose ranges can help you focus on what’s most representative of your day-to-day patterns, while still documenting events like sauna sessions, cold plunges, or sensor warm-up periods.
