How effective is Wegovy and how much weight can I expect to lose?

Whereas the trials have shown this to be very effective in the majority of patients taking it, like any medication, it is not guaranteed to work for you. You may either not tolerate it (have severe side effects) or not respond to it and find that it does not work for you.

The clinical trial by the manufacturers (STEP 1) showed that patients using Wegovy achieved an average weight loss of 14.9%. Of those:

• Almost 84% achieved a weight loss of less or equal to or greater than 5%
• Over 66% achieved weight loss equal to or greater than 10%
• Almost 50% achieved weight loss of over 15%
• Over 30% of patients lost more than 20% of their starting body weight.

Alongside taking wegovy, it is important to maintain a healthy diet and increase in physical activity.
