GLP-1 medications, including Ozempic and Wegovy, have become an increasingly common part of conversations around weight management and metabolic health. And as their use continues to grow, we're learning more about how these medications, and the changes that can accompany them, may affect the body beyond their intended benefits.
New research presented at the European Academy of Dermatology and Venereology (EADV) Congress 2026 found that nail changes were reported more frequently among people taking GLP-1 receptor agonists than among comparable people who were not taking them. Most notably, researchers observed a higher rate of nail detachment, also known as onycholysis, a condition in which the nail separates from the nail bed. The findings are interesting, but they're also a reminder that nail health is connected to the bigger picture of what's happening within the body.
WHAT THE RESEARCH FOUND ABOUT GLP-1 NAIL DETACHMENT
The multinational study compared 575 people taking GLP-1 receptor agonists with 1,329 people with type 2 diabetes and/or obesity who had never taken these medications. Participants were recruited across the United States, France, Brazil, and Mexico.
The researchers found that:
- 66% of GLP-1 users reported at least one nail disorder, compared with 53% of the control group.
- 39% of GLP-1 users reported nail detachment, compared with 9% of controls.
- 46% of GLP-1 users reported nail discoloration, compared with 17% of controls.
In other words, nail detachment was reported more than four times as often among GLP-1 users. But there's an important distinction to make: the study found an association, not proof that GLP-1 medications directly cause nail changes. The study was cross-sectional and relied on participants reporting their own symptoms. In fact, about half of the GLP-1 users reported having nail problems before beginning treatment. The researchers also found that accounting for dermatological conditions and nutritional deficiencies reduced some of the associations. More research is needed to understand exactly what's driving these changes.
WHAT IS NAIL DETACHMENT?
Nail detachment, or onycholysis, occurs when the nail plate begins to separate from the nail bed underneath it. It can appear as a white or yellow area underneath the nail where the nail is no longer attached to the skin. Depending on the cause, you may also notice discoloration, changes in texture, tenderness, or an increased tendency for the nail to catch on clothing or other objects. Nail detachment isn't exclusive to GLP-1 use. Trauma, certain medications, infections, inflammatory skin conditions, and underlying health concerns can all contribute to changes in the nail. That's why a new or persistent change shouldn't automatically be attributed to your medication.
YOUR NAILS CAN REFLECT WHAT'S HAPPENING WITHIN
It's easy to think of nails as purely cosmetic. But nails can sometimes provide clues about what's happening beneath the surface. Changes in nail growth, strength, color, texture, or attachment can be influenced by nutrition, medications, inflammation, trauma, and underlying health conditions. That means nail care isn't only about what you apply to the nail. It's also about creating the right environment for healthy growth.
WHAT CAN YOU DO TO SUPPORT HEALTHY NAILS?
While researchers continue to investigate the connection between GLP-1 medications and nail changes, there are simple ways to support overall nail health.
Prioritize balanced nutrition.
When appetite is reduced, making every meal count becomes even more important. Aim for a variety of nutrient-dense foods and adequate protein, and talk with your healthcare provider about whether you may need additional nutritional support.
Don't ignore persistent nail changes.
If a nail begins separating from the nail bed, changes color unexpectedly, or becomes painful, it's worth talking to a dermatologist or healthcare provider. Nail detachment can have many possible causes, and identifying the underlying issue is the first step toward appropriate treatment.
Be gentle with your nails.
Avoid picking or pulling at a nail that's beginning to lift. Keep nails at a manageable length and take care when filing or performing manicures to minimize additional trauma.
Pay attention to your nail routine.
Frequent exposure to water, harsh chemicals, aggressive filing, or picking can compromise the nail and surrounding skin. A consistent, nourishing nail-care routine can help support the health and appearance of your nails as they grow. For more nail-care tips, explore our guide to nail cycling.
NAIL HEALTH IS PART OF THE BIGGER PICTURE
The emerging research around GLP-1 medications and nail health is a good reminder that our nails aren't isolated from the rest of us.
What we eat, how our bodies respond to weight changes, the medications we take, and the way we care for our nails can all become part of the equation.
And while we still need more research to understand exactly why nail detachment and other nail changes appear to be more common among GLP-1 users, awareness is a good place to start.
At Dermelect, we believe healthy-looking nails begin with understanding what they need, not simply covering up what you see on the surface. That's why we create targeted nail treatments designed to address common concerns, from ridges and brittleness to dryness, helping you find the right care for your natural nails.
