General Signos FAQs 

What is Signos?

Signos is an all-in-one health tool that provides members with access to its app and a continuous glucose monitor (CGM). The CGM sends your glucose data via bluetooth to the Signos app, where you can see a continuous graph of your glucose, log what you eat and drink, track your weight, and get access to expert-created activities that teach you how little micro changes each day can have you living—and loving—a glucose-stable lifestyle. Sync your smart watches, smart scales, or Apple Health data to Signos for easier tracking of your health metrics.

How does Signos work?

Your individual glucose response combined with the meals and workouts you log provide the real-time data for our platform to recommend the foods that help keep your glucose stable. When you eat or drink something that spikes your glucose, our AI can recommend exercise and effort level based on your workout logs so you can bring your glucose back down more quickly. When your glucose levels remain mostly stable, in time, you’ll reap the benefits of more energy, improved mental clarity, better metabolic health, less risk of chronic diseases, and healthy weight management.

Do continuous glucose monitors (CGM) help with weight loss?

Yes, continuous glucose monitoring can help with weight loss when used to inform positive, long-lasting behavior changes. One study published in Clinical Diabetes found that 87% of CGM users modified their food choices based on the glucose data collected from the CGM. What’s more, 47% of CGM users said they were more likely to go for a walk or complete physical activity if they saw a rise in their blood sugar. Overall, 90% of participants felt that CGM use contributed to a healthier lifestyle. 

One study of 1,002 people found that glucose spikes and dips can relate to eating again sooner—and eating more calories at that meal and throughout the rest of the day. 

CGMs provide continuous glucose data so users can react accordingly and so they can be proactive about choices based on their current glucose level. 

Your glucose levels can be used as a tool for something called “appetite training,” or recognizing hunger signals. If your glucose is high—how high depends on the individual—this might be a cue that you have extra energy to burn. Maybe you still have energy from your most recent meal or long-term fat stores, and you could delay eating a snack or meal. 

Many people get hungry for reasons other than the need for energy—for example, social cues or boredom. But if you’re tracking your glucose via a continuous glucose monitor (CGM) and using the Signos app, you can check your glucose before you plan to eat to see if your glucose level is high. 

If your glucose is high (learn what “high” means and see normal glucose ranges for non-diabetics), you may have extra energy to burn so going for a brisk walk or doing 10 minutes of push-ups or kettlebell swings could be an ideal way to lower your blood sugar and possibly decrease appetite. Self-monitoring of glucose (via continuous glucose monitor or standard fingerstick glucose meters) can be an effective tool for weight and fat loss, particularly when paired with expert guidance that helps you understand which behaviors help you stabilize your glucose. 

For the latest information regarding the science behind glucose, insulin, fat storage and weight loss, read The Scientific Evidence for Using CGMs for Weight Loss.

Can I use Signos to manage my diabetes?

Signos currently only offers membership access to non-diabetics. If you’re diabetic and would like access to a CGM to track your glucose, talk to your doctor or diabetes management team. 

Should I be concerned about any potential allergens?

Our kits are shipped to you with our partner CGM device and adhesive patches that are typically applied on top of the sensor to keep it in place. Our patches are latex-free and made of a medical grade, hypoallergenic, acrylicsure polymer. In rare cases (<1%) if you are allergic to the sensor adhesive, you can apply the patch first and then the sensor on top of it. Some of our members with sensitive skin have seen success when applying Flonase to the application area before inserting the CGM sensor. 

Does the Signos membership include access to prescription medication?

No, we do not offer any prescription medications or medical supplements.

CGM & Device FAQs 

What is a CGM?

A continuous glucose monitor (CGM) is a tiny wearable device that reads the glucose levels in your interstitial fluids continuously. It is attached to your body (usually the upper arm or on the stomach) and continually monitors glucose levels via a microfilament—not to worry, it’s not uncomfortable to put on and you barely notice it’s there once applied.

For more information on CGMs and how they work, see How Does a Continuous Glucose Monitor Work.

How do I apply the patch?

The patch can be applied like a band-aid. You would first remove the adhesive cover, then place the patch with the central non-adhesive part over the CGM.

Do I need to scan or wand over my CGM?

You will not need to scan the CGM with your phone, as the device transmits data continuously—every 5 minutes—to your phone. To make sure your phone is capturing the readings, you just need to enable bluetooth, and make sure your phone is within 20 feet of you.

Can I take showers while wearing a CGM? What can (and can’t) I do with my sensor?

You can take showers, exercise, and even swim with your sensor. The sensor is designed to be able to work in up to 8 feet of water and at altitudes of up to 13,800 feet. You can also use it in a hot tub as long as the temperature does not exceed 107.6°F. Live somewhere tropical? No worries, the sensor can function in up to 95% humidity.

Is the device invasive?

The CGM device is minimally invasive. Each device has a filament the size of a kitten's whisker that sits just below the skin. You put a new sensor on every 10 days and just take off the old one (it's like peeling off a band aid).

Can I request patch and/or sensor replacements?

Yes, if a patch and/or sensor fails, you can request a replacement by writing to us at Please note: If you’re experiencing device issues, contact Signos Support BEFORE removing a sensor, and they will be happy to help you troubleshoot. Subscriptions do not include free replacements for devices incorrectly utilized or removed prematurely.

Can I use the CGM beyond 10 days?

Each sensor is designed to last for 10 days. You will be prompted from the Dexcom app to swap out the sensor to a new one after the 10 days are complete.

What should I do if I feel pain or discomfort from the CGM?

It is uncommon, but if you feel pain or discomfort, try changing the placement of your next sensor to another part of your body. We recommend not using the same location twice consecutively, but changing the location with every new sensor. If pain or discomfort occurs and you take your sensor off early, please contact You can stay on track by putting on one of the sensors in your package vs. waiting for the arrival of the replacement.
