How To Make Sure You Receive Critical Blood Sugar Alerts

Key takeaways


  • The FDA has issued a warning to users of continuous glucose monitors after reports of missed urgent blood sugar alarms on smartphones.
  • Free apps can act as a backup for CGM alerts on your phone.
  • A secondary alert system, like a CGM receiver or the SugarPixel standalone display, can ensure critical alerts are noticed.


The FDA recently issued a safety notice after receiving reports from CGM users who missed critical low and high blood sugar alerts on their smartphones. Some of the causes for the missed alerts included: changes to phone settings, operating system upgrades, and using Bluetooth accessories. 


The safety warning coincided with my own experience. Following an update to my smartphone, I missed two critical low blood sugar alerts during the night.


After missing those notices, I realized that I could back up my CGM alarms the same way I back up photos on my phone or laptop's hard drive. I then went about researching and testing other backup options, including these apps and devices I now use to make sure alarms are heard consistently, especially at night.

Sugarmate

The Sugarmate app is a popular way to connect and display readings from a Dexcom CGM account or the open-source software Nightscout, which connects to a wide range of CGM systems. The app can also make a phone call to a friend or family member if blood sugar is urgently low or high (note that Nightscout can also be set up to send audio blood sugar alerts or ones that change color on a web browser or watch).


The app works on Apple devices and CarPlay (you can ask Siri for your latest blood sugar reading). You can also choose to have it send a message to friends or family if your blood sugar is critically low. For Android phones and devices, you can save a web app to your home screen. Sugarmate also works on most desktop or laptop computers via web browser.


eddii

The free eddii app can make phone calls if you have an urgent high or low blood sugar reading. 


For eddii or Sugarmate, it's a good idea to add the phone number in the app to your emergency contacts on iPhone and Android so that your phone will ring even if it's muted or the volume is down. 


The eddii app also includes games centered around diabetes management, as well as the ability for virtual pediatric and adult endocrinology appointments via telehealth.

Optimal options for nighttime


Sweet Dreams

The Sweet Dreams app (for Apple devices) has been reliably notifying me of high and low blood sugar events, with audible alerts regardless of my phone’s volume level. The app also tells me the numeric difference of the current reading from the last one so I can quickly see if my blood sugar is rising or falling quickly. 


Sweet Dreams is also a good option for Abbott Freestyle Libre users who want to see readings on their Apple Watch. 


SugarPixel

As an alternative to app-based alerts, the SugarPixel device looks a bit like an alarm clock. It has a large bright display that shows your current blood sugar reading and can help users hear urgent alarms. The device's volume can only be set using a mobile app; there are no physical buttons to accidentally turn down and potentially miss an alert. 


The SugarPixel comes with a vibrating "puck," which resembles a small hockey puck and can be placed under a pillow to wake those who have hearing loss or prefer vibrations to wake them up (and possibly not their partner). 


CGM receiver

Some CGM devices, such as the ones from Abbott and Dexcom, come with a dedicated receiver, which can also act as a backup. The receiver and smartphones can work independently to alert you of urgent lows or highs. If you no longer have a receiver, call your insurance company to see if you can get a new one under warranty. 


The bottom line

For several reasons, urgent high and low blood sugar alerts can go unnoticed on smartphones, creating a potentially dangerous situation. Missed alerts could be caused by changes to phone settings, operating system upgrades, or using Bluetooth accessories, like headphones or car stereos. 


A CGM backup system can offer peace of mind in many scenarios: while sleeping, for those who live alone, for anyone traveling alone, or for parents with kids at a sleepover. 


One way to back up your alerts is through free apps, which can send notices that will alarm even if a phone is on mute or the volume is turned down. Some apps can also make a phone call to friends or family, letting them know of an urgent low or high. 


Other backup options include a CGM receiver, if your system offers one, or a device like the SugarPixel, which has accessibility features designed to assist those who are hard of hearing or have vision loss.


Here are some additional tips recommended by the FDA to avoid missing urgent alarms:


  • Turn off automatic operating system upgrades.
  • Wait to install operating system upgrades until the device manufacturer releases a compatible version of the app.
  • Check alerts after connecting to accessories, such as wireless headphones or car audio systems, which may lower the alert volume or cause alerts to not work at all.
  • If alerts are not being delivered as expected, contact technical support for the device.
  • Report any unresolved problems with diabetes devices using the FDA's  MedWatch site.

Americans are drinking more sugar than ever before, and it's not just the amount that's fueling today's metabolic crisis. It's the form. When refined sugar is consumed in liquid form, whether in sodas, flavored waters or sports drinks — it bypasses your body's natural defenses. There's no chewing, no fiber, no fullness. Just a rapid flood into your bloodstream that forces your pancreas and liver to respond instantly. This kind of metabolic ambush happens quietly at first, but over time, it rewires how your body handles insulin, stores fat and manages energy. You might assume sugar only becomes a problem if you're overweight. But research now shows that even lean people are at risk when that sugar comes from a bottle or can. The damage starts below the surface, long before you feel symptoms or see changes on a scale. If you're drinking soda daily, or if your children are, this isn't just about empty calories. It's about how those drinks hijack your metabolism, starting with the very first sip. And if you want to protect yourself from insulin resistance and its many downstream effects, understanding how different types of sugar behave in the body is the first step.

This is like a cross between an unfussy lasagna and a baked ziti: Cheesy, rich, and deeply satisfying, despite the actual absence of noodles. Even my daughter, who tends to be totally skeptical about “fake vegetable pasta dishes,” loves it. Don’t be daunted by the ribboning of the zucchini with a vegetable peeler: It honestly doesn’t take that long, and the resulting strands are thinner and wider and just generally more noodle-like than what you’d get with a spiralizer. That said, if you want to start with a pound of zoodles, go ahead – just be sure to salt and drain them really well or the resulting dish will be watery. One last thing: If you’d prefer a meat sauce, go ahead and brown a pound of ground beef after you sauté the onions and before you add the tomatoes – and expect the dish to feed more people that way. Makes: 8 servings Total carbohydrates: 15 grams per serving Active Time: 50 minutes Total Time: 1 ½ hours Ingredients 3 medium-sized zucchinis (around 1 pound) 2 teaspoons kosher salt (or 1 teaspoon table salt), divided, plus more as needed ¼ cup olive oil 1 onion, finely chopped 3 cloves garlic, finely chopped (or 1 teaspoon garlic powder) 1 (28-ounce) can tomato purée or crushed tomatoes Black pepper 1 (16-ounce) container whole-milk ricotta ½ cup heavy cream ½ cup grated Parmesan ¼ teaspoon nutmeg 1 pound whole-milk mozzarella, grated, sliced, or diced Instructions

Type 2 diabetes, a condition marked by chronically high blood sugar levels, is a leading driver of metabolic disease in America. While conventional medical advice recommends taking medications to control blood sugar levels, this is only a temporary measure at best.  Diabetes is compounded by several factors, and recent research notes that nutritional deficiencies is a commonly overlooked aspect, and that when these deficiencies are addressed, managing and controlling this disease becomes easier.

Telemedicine can make diabetes care less expensive and easier to access, but it may not always be a suitable replacement for an in-person visit. Learn what happens during a telehealth visit and see if you could benefit from using telemedicine for your diabetes care. The pandemic upended a lot about life as we knew it. Notably, it was responsible for a 63-fold increase in telehealth visits . For people managing diabetes, however, having a doctor visit over video brings up a host of questions and potential issues. How can a doctor properly check my eyes and feet through a computer screen? Will telehealth replace in-person discussions about my blood sugar? Will I get the same level of care through a computer? According to a 2022 article in American Family Physician , telehealth is promising for diabetes treatment and has been shown to help improve glucose management. In a separate analysis of glucose data from people with type 2 diabetes, people who received remote monitoring of their glucose levels saw significant improvements in A1C over a period of three months. That being said, no study or physician is implying that telehealth fully replaces in-person medical care for diabetes. Here’s what to consider and who might be the best candidates for telediabetes care. What happens during a diabetes telehealth visit? Telediabetes care involves two types of interactions. One is a video meeting with a physician or care team to discuss challenges and potential solutions. During this type of visit, the healthcare provider can see some physical signs or changes, such as rashes or wounds. The second type of interaction is virtual monitoring of glucose levels through a monitoring device that sends data to the care provider. The provider might also follow up with a video call to discuss the data. “Many of the things that are important for diabetes care – blood glucose data review, medication review, insulin teaching – can all happen over video,” said Dr. Varsha Vimalananda, an endocrinologist and associate professor of medicine at Boston University. “CGM data can be uploaded and reviewed remotely, which is also very helpful.” Different providers use different video platforms for telehealth appointments, but most will look and function much like a Zoom call. The benefits of telehealth in diabetes care Not all elements of diabetes care are best suited for telehealth, but many lend themselves naturally to the conversation and convenience that an electronic visit facilitates. For type 2 diabetes in particular, telehealth has been shown to be more effective than in-person care at helping people manage their condition. One reason for the improved outcomes is simply better access to care. Dr. Keta Pandit, an endocrinologist at Texas Diabetes & Endocrinology in Austin, Texas, says continuous glucose monitoring (CGM), along with telehealth options, have changed the landscape of diabetes care. “One of the benefits of being able to offer telemedicine to our patient population is that it has increased the access to care, especially with any ongoing illnesses, hospitalizations, COVID, post-COVID, or any other situations when patients notice their glucose levels are going out of their standard range. Patients often contact us for these types of situations, and we can quickly get them seen via telemedicine to make adjustments to their diabetes medications,” she says. “While this was still an option prior to telemedicine days, the opportunity to see their provider on short notice, not having to worry about transportation, and not having to put in advance notice to take time off of work to travel to the doctor’s office, are some of the ways access to care has increased.” Pandit says this is particularly true for older patients who require frequent visits and women who are pregnant, as well as those who need to optimize their glucose levels before and after surgery. Jasmine Meidas, 51, of Cleveland, Ohio, is one such patient. She was diagnosed with type 2 diabetes 15 years ago. “During the COVID-19 pandemic, I was much more comfortable with telehealth than going into my endocrinologist’s office, which is in a hospital. I still am,” she says. Meidas has a one-hour telehealth visit every three months. “They can order blood work to be taken locally, [and] we review [the results] together. We also review food choices, lifestyle challenges, stressors, and more. We set action steps and goals for the next 90 days,” she says. Meidas periodically sees her endocrinologist in person as well. At Vimalananda’s clinic in Boston, specific groups are making great strides with telehealth options. “Veterans, mostly,” she says. “I have a few [Veteran patients] who have severe [post-traumatic stress disorder]. Driving out to the clinic, dealing with traffic, and navigating the hospital are all things that cause a lot of distress. It’s been a game-changer for them to be able to have the visit from home.” When is telehealth not the best option? “If you have diabetes, please remove your socks and shoes.” This type of sign is frequently displayed in doctors’ offices. How would a foot exam work in telehealth? This is a real concern for people with diabetes, as up to 15% of patients will have a foot ulcer in their lifetime. Pandit and other experts acknowledge the limitations telehealth can have. “The medical team [must depend] on the patient [to provide] data and limited access to other parameters that are needed, including blood pressure measurements or foot examinations. When visits are conducted via telemedicine…care is not as comprehensive,” says Pandit. “There are times when the telemedicine model may pose risks. The limitation is clearly noted in visits with patients who are not technologically savvy, may have hearing issues, or [have] poor [internet] connection at the time of the visit.” Telehealth can also give health care providers a direct view into the home environment, which may result in a patient’s hesitancy to share openly — with family members potentially nearby — and impede the building of relationships and rapport. For these reasons, Pandit recommends that at least every other visit be conducted in person.

Marcia Kadanoff, who lives with type 2 diabetes, shares her top five tips for enjoying a Valentine’s Day meal out. Pink and red hearts everywhere, overpriced dinners, wondering if you’ll have a date (or if you got your partner an appropriate gift) – ah, the joys of Valentine’s Day. I’m stressed just thinking about it. As a person with diabetes, my stress may be a bit different than general Valentine’s Day anxiety. By this point, my spouse knows enough not to get me chocolates, my biggest landmine food. But the hard thing for Valentine's Day or any other romantic occasion is getting a reservation at the right kind of restaurant and – as always when living with diabetes – planning out my meal. Special occasion meals take special skills to navigate. The good news is that there are definitely strategies that can help make a romantic dinner somewhere special enjoyable without diabetes taking center stage. Where I live – the San Francisco Bay Area – many restaurants have Valentine’s Day dinner specials that consist of three to five courses. There’s nothing wrong with eating a multi-course meal, but it does make diabetes management more difficult. From bread to creamy soups and crouton-laden salads to heavy entrées to a dessert that’s potentially cake-filled, multi-course meals can quickly add up to a large amount of carbohydrates, which is a major driver of high blood sugars. The reality is that even if I choose the “healthier” set menu for a celebratory multi-course meal, I still make a point to think about what each portion is bringing (quite literally) to the table. Here are my best tips for navigating a Valentine's Day dinner out.
