Managing Type 2 diabetes requires constant vigilance, careful monitoring, and deep trust in medical technology. For Michael Ford, a 68-year-old man living in Oakland, California, that trust became central to his daily survival. Although his health had challenges, his diabetes remained under control with the help of modern glucose-monitoring technology and the devoted care of his son, Davonte Ford.
Davonte served as his father’s full-time caregiver, handling medications, monitoring blood sugar levels, and assisting with everyday needs. Like millions of families managing diabetes, they depended heavily on a continuous glucose monitoring system designed to provide real-time health data and prevent dangerous complications.
One November morning, their routine changed forever.

A Warning That Came Too Late
Michael’s glucose monitor issued a low blood sugar alert, prompting Davonte to act immediately. Following medical guidance, he gave his father fast-acting carbohydrates to raise glucose levels. The reading appeared serious, and there was no reason to doubt the device’s accuracy.
Unbeknownst to them, the sensor reading was allegedly wrong.
Eight days later, the manufacturer issued an urgent warning stating that millions of glucose sensors could produce falsely low readings. Reports connected the issue to multiple deaths and hundreds of serious injuries worldwide. By then, the Ford family had already experienced devastating consequences.
According to a lawsuit later filed by Davonte, the device displayed dangerously inaccurate numbers that led him to repeatedly treat a condition his father did not actually have.
Confusion During a Medical Emergency
When Michael’s glucose level appeared stuck at a low number despite sugar intake, Davonte grew concerned. He provided sweetened drinks and snacks, hoping to stabilize the readings. Instead of improving, Michael’s condition worsened. His speech slowed, and he became increasingly unresponsive.
Panicked, Davonte called emergency services.
Paramedics arrived and performed their own blood sugar test. The result shocked everyone present: Michael’s glucose level measured 551 milligrams per deciliter — more than three times the normal range and dangerously high.
The monitor had indicated low blood sugar, while his actual condition was severe hyperglycemia.
Michael was rushed to the hospital, but despite intensive treatment, he died the following day after suffering multiple cardiac arrests.
Diabetes Management Depends on Accuracy
Diabetes affects tens of millions of people and requires precise monitoring to prevent life-threatening complications. Blood sugar that drops too low or rises too high can quickly become fatal. Continuous glucose monitors (CGMs) were developed to simplify this process by replacing frequent finger-stick testing with automated, around-the-clock tracking.
These devices measure glucose levels through tiny sensors placed under the skin, sending updates directly to smartphones or monitoring systems. For patients and caregivers, they offer convenience, independence, and early warnings of potential danger.
Medical experts have long considered CGMs a transformative innovation in diabetes care. Real-time data allows patients to adjust food intake, medication, and activity levels quickly. However, accuracy remains essential because treatment decisions rely entirely on the numbers displayed.
When those numbers fail, consequences can be severe.
Recall Sparks Legal Action and Patient Concerns
The large-scale recall involving millions of sensors has triggered multiple lawsuits across the United States. Families and patients argue that warnings about potential device failures were insufficient and arrived too late to prevent harm.
Several individuals claim they suffered medical emergencies after relying on incorrect readings. Some cases involve repeated hospital visits after monitors reported dangerous glucose levels that later proved inaccurate.
Questions have also emerged about whether all defective devices were properly included in the recall. Some affected patients reported owning sensors not listed in official recall batches despite experiencing similar problems.
The situation has intensified debate about how medical device recalls are communicated and whether monitoring systems should include stronger safeguards.
Technology That Changed Diabetes Care — and Its Risks
Continuous glucose monitors revolutionized diabetes management when introduced more than two decades ago. Doctors praised them as a breakthrough that reduced the burden of constant manual testing while improving long-term health outcomes.
Unlike traditional methods requiring repeated blood samples, CGMs collect glucose data automatically through sensors attached to the arm. Patients receive alerts when levels move outside safe ranges, allowing faster intervention.
Despite their benefits, experts emphasize that these systems remain technological tools rather than flawless solutions. Hardware defects, production issues, or software errors can occasionally occur.
When failures happen in medical devices, risks extend beyond inconvenience. Incorrect health data can directly influence life-saving decisions, turning a helpful tool into a potential hazard.
Patients Describe Fear and Loss of Confidence
Many diabetes patients say discovering flaws in devices they rely on daily has shaken their confidence. Some reported rushing to emergency rooms after receiving repeated low-glucose alerts, only to learn their levels were normal.
Others described lasting anxiety, disrupted sleep, and fear of experiencing unnoticed medical emergencies. Several patients returned to traditional finger-stick testing after losing trust in automated monitoring.
For older adults and individuals living alone, emotional stress has been particularly significant. Continuous monitoring systems often provide reassurance and independence; losing confidence in them can feel like losing control over personal health.
Hospitals and Providers Face New Challenges
The recall also revealed challenges within healthcare systems. In at least one case, a medical professional discovered that a patient had been sent home with a recalled sensor still in circulation. The device was replaced immediately, highlighting how quickly recalled products can remain in use if communication gaps exist.
Healthcare organizations now face increased pressure to verify device safety, monitor recall updates, and educate patients about backup testing methods.
Medical associations recommend keeping finger-stick glucose testing available, especially when symptoms do not match device readings. Experts stress that physical symptoms should never be ignored, even when technology suggests otherwise.
Balancing Innovation and Safety
Medical technology continues to advance rapidly, offering new tools that improve quality of life for chronic disease patients. Continuous glucose monitoring remains widely regarded as a major advancement that helps millions manage diabetes more effectively.
However, the recent recall underscores an important lesson: innovation must be matched by rigorous quality control and transparent communication.
Manufacturers regularly monitor device performance and investigate reported issues, but patients and caregivers depend on timely alerts to make informed decisions. Delays or unclear messaging can create confusion during critical moments.
For many families, the incident has sparked broader discussions about accountability, testing standards, and the role of technology in healthcare decision-making.
A Son’s Grief and a Lasting Reminder
Beyond lawsuits and industry scrutiny lies a deeply personal story of loss. Davonte Ford remembers his father not as a patient defined by illness but as a caring man who loved music and enjoyed playing the piano.
He continues to grapple with guilt, questioning whether different actions might have changed the outcome. Like many caregivers, he trusted the medical device designed to guide life-saving decisions.
That trust, he believes, ultimately failed them.
Michael Ford’s story highlights both the promise and vulnerability of modern healthcare technology. Continuous glucose monitors remain powerful tools, yet their effectiveness depends entirely on reliability.
For millions living with diabetes, the recall serves as a sobering reminder: technology can enhance care, but awareness, backup methods, and human judgment remain essential safeguards in protecting lives.
