What the FDA's 2026 wellness rules let your wearable tell you
A January guidance opened the door for watches and rings to estimate blood pressure and glucose without FDA review, as long as they stay away from diagnosis.

This is a look back at an event from . We wrote it on November 11, 2026, from the sources listed at the end.
What to know
- The FDA issued a revised general wellness guidance on January 6, 2026, replacing the 2019 version.
- Noninvasive wearables that estimate measures such as blood pressure, blood oxygen, blood glucose and heart rate variability can qualify as wellness products.
- A product that names a disease, gives a clinical threshold or claims clinical-grade accuracy is still treated as a medical device.
If your watch or ring has gained new health readings this year, a policy change is part of the reason. On January 6, 2026, the Food and Drug Administration issued a revised version of its general wellness guidance, the document that describes which health products the agency does not intend to regulate as medical devices. This summary draws on an analysis by the law firm Cooley.
What changed
The earlier guidance, from 2019, did not clearly address wearables that estimate body measurements. The new one does. It says the FDA's hands-off policy can cover noninvasive products that estimate or infer measures such as:
- Blood pressure
- Blood oxygen saturation
- Blood glucose
- Heart rate variability
Noninvasive is the important word. A sensor that sits on your skin can qualify. One that goes under your skin cannot.
The conditions
A product qualifies only if its readings are used for wellness. In practice that means the outputs must not be intended to diagnose, treat or manage a disease, must not replace an FDA-authorized device, and must not push the wearer toward a specific medical action.
Alerts are now allowed, within limits. A wearable can tell you a reading is outside a wellness range, but only if the alert tells you to see a healthcare professional. It cannot name a disease, call the result abnormal, cite a clinical threshold or suggest a treatment.
What still makes something a medical device
| The product says or does this | How it is treated |
|---|---|
| "Your blood pressure estimate has trended higher this week" | Can qualify as wellness |
| "Your readings are outside your usual range. Consider checking in with a healthcare professional" | Can qualify as wellness |
| "You may have hypertension" | Medical device |
| "Clinical-grade accuracy" or "replaces your cuff" | Medical device |
| Tells you to change a medication or dose | Medical device |
What it means for you
A wellness reading has not been reviewed by the FDA for accuracy. It can be useful for spotting a trend in your own data. It is not a substitute for a measurement from an authorized device, and the product is not allowed to suggest that it is.
Cooley points out a tension in the guidance. It says wellness products may help people live well with certain chronic diseases, but it also bars references to disease in labels and alerts. Expect companies to word their features carefully, and expect the wording to tell you which side of the line a feature sits on.
