What is Wegovy, and what is it used for?

Wegovy is a prescription-only, GLP-1 receptor weight loss medication containing Semaglutide as the main ingredient. Injected once weekly, it has shown 15% weight loss over 68 weeks when combined with lifestyle changes.

What is a GLP-1, and how does Wegovy help patients lose weight?

GLP-1 is a naturally occurring hormone responsible for regulating appetite and helping you stay full for a long time. Wegovy mimics the action of GLP-1 and helps your body stay satiated by controlling appetite and reducing cravings.

Studies have shown that eating habits become easier to control when combined with sustained physical activity. Wegovy is effective because it directly acts on appetite pathways, so patients don’t have to rely on willpower alone.

Over time, this change in appetite helps create a sustained calorie deficit—crucial for meaningful weight loss. Step by step, people build consistent routines around food, activity, and sleep—the pillars of long-term weight management.

How is Wegovy injected into the body?

Wegovy comes as a pre-filled injection pen that you use once a week. It is only for your personal use and should never be shared with anyone else.

• Pick a day of the week that is convenient for you.

What are the possible side effects of Wegovy?

Most side effects of Wegovy are mild to moderate, especially at the beginning of treatment, and tend to improve as your body adjusts. Because Wegovy works on the digestive system, many of the most common effects are related to the stomach and bowels.
