Wegovy Injection Sites: Abdomen, Thigh, and Upper Arm
The three sites recommended for Wegovy injections are the same ones used for most subcutaneous injectable medicines. Each has practical considerations worth knowing about.
Abdomen
The abdomen (stomach area) is one of the most commonly used sites. Injections should be given into the fatty tissue, avoiding the area immediately around the navel. Many people find the abdomen easy to access for self-injection.
Front of the thigh
The front and outer area of the thigh is another suitable location. If you are searching for guidance specifically on injecting Wegovy step by step, your prescriber or the patient information leaflet that came with your pen are the best sources for technique. The thigh can be a practical choice when the abdomen is sore or you simply want to alternate.
Upper arm
The outer area of the upper arm is also listed as a suitable site, though self-injection here can be less straightforward than the abdomen or thigh. If someone is helping you with your injection, the upper arm is a convenient option.
Why rotation matters
Using the same spot repeatedly can cause lipohypertrophy — a build-up of fatty tissue under the skin that can affect how the medicine is absorbed. Rotating systematically across different sites (and different spots within each site) helps avoid this. This principle applies to all subcutaneous injectable medicines; you can find general guidance on subcutaneous injection site rotation in the electronic Medicines Compendium (eMC), where the full Wegovy prescribing information is published.
If you are also curious how injection site choices compare across medicines, the approach for Mounjaro injection sites follows a very similar three-site rotation principle, which may be useful context. For a visual overview of injection considerations, thigh injection guidance covers practical positioning that many people find transferable.

Tracking Your Wegovy Injection Sites with GLP Trackr
Keeping a reliable record of which site you used — and when — makes rotation much easier to manage over a long weekly schedule. GLP Trackr's injection-site tracking feature lets you log each injection by location (abdomen, thigh, or upper arm), and the app uses your history to suggest which site to use next, so you are never guessing or relying on memory.
Alongside site logging, the app records the date and dose strength of each injection and sends you a gentle reminder when your next weekly dose is due — useful for keeping your schedule consistent. You can also use the side-effect log to note any local reactions at a particular site, which can be helpful information to bring to your next appointment.
GLP Trackr is part of a broader toolkit for managing your Wegovy journey — you can explore the full picture of weight-loss injection tracking to see how dose logs, progress charts, and insights all connect.
Ready to take the guesswork out of rotation? Download GLP Trackr on the App Store or Google Play and start a free 7-day trial — your injection history will be there every week when you need it.
Always follow the injection guidance provided by your prescriber or doctor and the patient information leaflet supplied with your pen. If you notice persistent skin changes, pain, or unusual reactions at an injection site, contact your healthcare professional promptly. GLP Trackr helps you record what you observe — it is not a substitute for clinical advice.

The Most Advanced GLP-1 Brain Ever Built.
The first AI built exclusively for GLP-1 weight loss. Every insight, every meal plan, every prediction trained on one thing only: helping you get the most out of your medication.
Knows Your Cycle
GLPIQ tracks where you are in your injection cycle and adjusts everything around it: lighter meals on nausea days, higher protein when appetite returns, and smarter targets as your medication level shifts.
Predicts Before You Feel It
GLPIQ learns your personal side effect patterns over time. After a few cycles, it starts warning you the morning before a rough day — and adjusts your meal plan automatically.
Finds Your Golden Dose
GLPIQ analyses every dose you've been on: weight loss rate, side effects, food noise, mood, protein adherence and tells you which dose gave you the best results. No other app does this.

Frequently asked questions.
Wegovy is injected subcutaneously into one of three sites: the abdomen (avoiding the area around the navel), the front of the thigh, or the outer upper arm. Your prescriber or the patient information leaflet will confirm the exact technique recommended for you.
Yes. Rotating between sites each week — and varying the exact spot within each site — helps prevent skin and tissue changes caused by repeated injections in the same place. Your prescriber or the leaflet supplied with your pen can advise on a rotation pattern.
All three recommended sites (abdomen, thigh, upper arm) are considered suitable. Many people find the abdomen easiest for self-injection, but the best choice depends on personal comfort and your prescriber's guidance. Consistent rotation across sites matters more than always using any single one.
GLP Trackr lets you log each injection by site and date. The app uses your logged history to suggest which site to use next, removing the need to remember your rotation schedule manually. Dose reminders are also included to keep your weekly schedule on track.
Some redness or mild discomfort at an injection site is commonly reported. If you notice persistent lumps, pain, or unusual skin changes, contact your healthcare professional promptly. You can log any reactions in GLP Trackr to share the pattern with your prescriber.
