Wegovy Injection Sites: What You Need to Know
Wegovy is a once-weekly subcutaneous injection, meaning it is delivered into the fatty tissue just beneath the skin. According to the medicine's prescribing information, the recommended areas are the abdomen (stomach area, avoiding the two inches around the navel), the front of the thigh, and the upper arm. All three are widely used; your prescriber or doctor can advise which is most suitable for you based on your individual circumstances.
Why rotation matters
Injecting repeatedly into exactly the same spot can cause a condition called lipohypertrophy — a build-up of fatty tissue under the skin that can affect how the medicine is absorbed. Rotating sites (and varying the precise location within each site) helps keep the surrounding tissue in good condition. Many people find it useful to follow a simple pattern — for example, moving around the abdomen in a clockwise direction, or alternating between left and right thigh each week.
Does the injection site affect weight loss results?
There is no strong evidence that one specific site leads to meaningfully different weight-loss outcomes compared with another. What matters more is that injections are given consistently, that sites are rotated properly, and that each shot is delivered subcutaneously as directed. If you have questions about your technique or which site is right for you, your prescriber or doctor is the best person to ask. You may also find it helpful to read a closer look at how Wegovy injections work for more context on the process.
Choosing between sites
Some people find the abdomen convenient because it is easy to reach and offers a relatively large surface area to rotate around. Others prefer the thigh for ease of access when sitting down, or the upper arm if self-injecting there feels comfortable. Personal preference, body composition, and any site-specific reactions you experience are all worth noting — and logging — so you can discuss them with your prescriber. For a comparison with how injection sites work on tirzepatide, the guide to Mounjaro injection sites covers the same principles. More general guidance on managing weight-loss injections is available in the weight-loss injections overview.

How GLP Trackr Helps You Stay on Top of Site Rotation
Keeping a mental note of which site you used last week — and exactly where within that site — is surprisingly easy to lose track of, especially once you settle into a routine. GLP Trackr's injection-site tracking feature is built around this exact challenge: log each injection (site, date, and dose strength) and the app maintains your rotation history, so you always know where you injected last and where to go next.
Alongside site tracking, the app's dose reminders mean your once-weekly schedule stays on track without you having to rely on memory. And if you ever notice a reaction at a particular site — redness, tenderness, or a lump — the side-effect log lets you record it in context alongside your injection history, giving you a clear picture to share at your next prescriber appointment.
If you want a broader view of how people manage their Wegovy injections day to day, the detailed guide to Wegovy injection sites covers common questions in more depth.
Any concerns about injection-site reactions, technique, or how your body is responding should be discussed with your prescriber or doctor — they know your full history. If a reaction is severe or persistent, contact a healthcare professional promptly. GLP Trackr helps you record what you experience; it is not a substitute for clinical advice.

Frequently asked questions.
The recommended injection sites for Wegovy are the abdomen, front of the thigh, and upper arm. There is no single site proven to improve weight-loss results more than another — consistent injection and proper rotation matter most. Your prescriber or doctor can advise on the best site for you.
Yes, in the sense that rotating between sites helps keep the tissue healthy and supports consistent absorption. Injecting repeatedly in exactly the same spot can cause tissue changes under the skin. Varying the location within each site, and rotating across sites over time, is generally recommended.
Yes. Rotating between recommended sites — and varying the precise spot within each site — helps prevent localised tissue build-up (lipohypertrophy), which can affect how the medicine is absorbed. Many people find a simple rotation pattern, such as moving around the abdomen each week, helpful to follow.
Yes. GLP Trackr lets you log each injection site, date, and dose, and keeps a rotation history so you always know where you last injected. You can also record any site reactions in the side-effect log to discuss with your prescriber.
Minor redness or tenderness at an injection site is commonly reported and often temporary. If a reaction is severe, spreading, or persists, contact your healthcare professional promptly. Log what you observe in GLP Trackr so you can describe it accurately at your next appointment.
