The Dexcom G6 and G7

The device is indicated for use by people with type 1 diabetes 6 years of age and older.

The device is protected up to 12 feet of water for up to 30 minutes

The iLet is different from any other insulin delivery device, as you cannot program any insulin settings or control any of the insulin dosing. The iLet can take a few days to learn how to best take care of your diabetes. The iLet will work best if you let it do the work for you. We recommend that you avoid overthinking what the iLet is doing.

Yes. You may still have low blood glucose levels (hypoglycemia) that you will need to treat with fast- acting sugar. The iLet will reduce or stop insulin dosing automatically in response to low CGM levels. You will still need to treat low blood glucose levels while using the iLet.

No. You cannot give additional insulin boluses when your blood glucose levels are high (hyperglycemia). The iLet automatically tries to give you insulin to bring your blood glucose down (this may take longer than you expect). You may need to change your infusion set or tubing and cartridge if you think your high blood glucose levels could be due to a problem with your insulin, tubing, or set. When in doubt, change it out!

When you eat meals, you should enter a Meal Announcement into the iLet. There is no need to count carbohydrates, and the iLet does not use a carbohydrate-to-insulin ratio. Instead, you tell the iLet if the amount of carbs you are eating is Usual for you, More than usual, or Less than usual. The iLet will use this information to determine how much insulin to give you. You cannot choose the exact dose of insulin (this has made some people uncomfortable in clinical studies).

The iLet will automatically give you insulin as your blood glucose rises, but it will not be able to track and learn from your meals. Your blood glucose may go higher and stay higher for longer than if you had announced the meal. 

CAUTION: This may lead to hypoglycemia later due to the correction algorithm adding more insulin than it would have if you had announced the meal.

You can announce a meal up to 30 minutes after you start eating. If you forget to announce your meal, and more than 30 minutes have passed since you started eating, do not announce the meal. If you forget to announce your meal, the iLet will automatically deliver insulin in response to your rising CGM levels. Your blood glucose levels may go higher and stay higher for longer than if you had used the Meal Announcement feature. Having a low blood glucose later is also more likely.

CAUTION: After 30 minutes your glucose is already rising and the iLet has already dosed insulin according to your rising CGM levels, even without a meal announcement. If you announce a meal during this time, you will “stack” insulin and be at risk for severe hypoglycemia. This will also confuse the iLet, causing future meal doses to be less effective.

No. Do not announce a meal for carbohydrates used to treat low blood glucose.

CAUTION: This could cause additional hypoglycemia and is dangerous.

No. You cannot change insulin doses with the iLet. All insulin doses are automatically calculated by three separate algorithms which are continuously learning. The only action you can take to influence insulin delivery is to issue a Meal Announcement before eating a meal, or to disconnect from the iLet temporarily. Blood glucose control will worsen if you try to trick the system

You do not need to eat a bedtime snack to keep your blood glucose in range overnight while using the iLet. If you chose to eat before bed, you should announce it to the iLet the same as you would during the day. This will give you insulin upfront and help prevent additional dosing in response to the rise in glucose after you eat. This will reduce the risk of hypoglycemia during the night.

No. If you eat a very low carb diet or no carbs at all, you should not announce meals. 

No. This can be dangerous. 

CAUTION: It could lead to severe hypoglycemia and confuse the iLet, causing future meal doses to be less effective.

No. Do not announce a meal that is larger than the actual meal size to correct high glucose levels. The iLet will have already delivered correction insulin in response to your high glucose. 

CAUTION: Announcing a larger meal than the actual size could lead to severe hypoglycemia and confuse the iLet, causing future meal doses to be less effective.

No. The iLet does not use insulin to carbohydrate ratios to dose insulin for meals. Do not calculate the amount of carbohydrates you need based on the insulin dose your iLet gave you. This will affect the iLet’s ability to learn about your insulin needs and confuse the iLet, causing future meal doses to be less effective.

You may need to take a few days and focus on helping the iLet learn about your meals. Be consistent with how you decide the meal type and size. 

• Only select Breakfast if you are eating your breakfast, Lunch for your lunch, and Dinner for your dinner. 
• Only think about the carbs in your meal when selecting the size, not the amount of fat or protein. 

Try to eat meals that have carbs in the Usual for me range and wait at least 4 hours before eating and announcing again.

 After a few days, your meal dose(s) should adapt. Refer to the Meal Announcement Guide for more information on meal announcements and helping the iLet adapt.
