Does the Injection Site Affect Side Effects?

Not usually. Common Wegovy side effects—including nausea, vomiting, constipation, diarrhea, or reduced appetite—are primarily caused by semaglutide itself, not by where you inject it. However, you may notice slight differences in comfort depending on:

• Skin sensitivity
• Thickness of fatty tissue
• Injection technique

Some people experience mild redness, itching, bruising, or swelling at the injection site, but these reactions are generally temporary.

Why You Should Rotate Injection Sites

Using the same wegovy injection spots every week may increase the risk of:

• Skin irritation
• Bruising

• Tenderness
• Injection site reactions

Instead, rotate your injection site every week. For example:

• Week 1: Right side of stomach
• Week 2: Left side of stomach
• Week 3: Right thigh
• Week 4: Left thigh

Even if you continue using the same body area, inject at least an inch away from your previous injection site.
