View compareWhat is Wegovy?
Wegovy is a medicine intended to encourage weight loss, self-administered as an injection; it comes in pre-filled injection pens. It’s designed to assist individuals on their weight loss journey. It contains the active ingredient semaglutide, which mimics the body’s own hormone GLP-1 (“glucagon-like peptide 1”), and it regulates appetite and promotes feelings of fullness.
Wegovy is convenient as it only needs to be administered once a week, and is an option for adults with a body mass index (BMI) over 30, or those with a BMI over 27 who have other weight-related health conditions, as an addition to a reduced calorie diet and an increase in levels of physical activity.
Who can use it?
Wegovy is suitable for individuals who meet specific criteria and are seeking effective help with weight loss.
-
Adults with obesity (BMI over 30)
-
Adults who are overweight (BMI higher than 27) and have weight-related health conditions such as high blood pressure
The Medicines and Healthcare products Regulatory Agency (MHRA) has now granted approval for semaglutide as a preventative treatment to reduce the risk of heart attacks, strokes, and cardiovascular death in overweight and obese adults.
In a 2024 trial carried out by SELECT, semaglutide was found to reduce the risk of a repeat cardiac event by 20% in patients with a BMI of 27 or higher who had experienced a cardiac event previously.
Who can't use it?
Wegovy isn't suitable for:
-
People with a history of allergic reactions to semaglutide or any of the other ingredients in Wegovy
-
Those experiencing diabetic retinopathy
-
Individuals with kidney problems
-
Those at risk of pancreatitis
People with diabetes should talk to their NHS GP about weight loss medicines, because Wegovy could interact with other medicines prescribed for this condition.
