Read what leading weight management professionals had to say about Wegovy and Mounjaro:

Wegovy and Mounjaro have transformed the treatment of obesity, particularly for those with BMIs of 27-40 who are not eligible for, or wish to avoid, bariatric surgery. Used in conjunction with a high quality support programme, there is an excellent chance of achieving clinically beneficial weight loss.

Professor David Kerrigan

SemaPen Founder and Bariatric Expert

We all know that losing weight and keeping it off is difficult. But GLP-1 agonists enhance natural signals between the gut and the brain that make you feel full sooner, and could help you achieve and maintain weight loss

FAQs

Here are answers to some of the most commonly asked questions about The SemaPen Programme.

For a more detailed list of FAQs, please visit Semapen FAQ Page.

How much weight will I lose?

Reputable clinical trials* found that if you use weight loss injections as part of a comprehensive weight loss programme involving dietetic support and lifestyle modification (calorie restriction and some regular exercise) an average outcome is to lose about 15% -21% of starting body weight after a year, depending upon the drug used.

It is unlikely that you will achieve this amount of weight loss with the injections alone, which is why the 12-month SemaPen programme is so important.

Remember, 15% -21% weight loss were average outcomes, but some people in the trials lost more than this and others will have lost less.

Will I lose all enjoyment of food if I use weight loss injections?

Absolutely not!

Wegovy and Mounjaro do not alter the taste of food, they work by suppressing your appetite.  You will also start to feel full much sooner than normal. This dual action makes it much easier for you to avoid snacking and to control the size of your main meals.

You can still enjoy the pleasure of lovely food, but the medications put you in control, so you are able to moderate your calorie intake.

 

Will I have side effects?

Like all medications, Wegovy and Mounjaro may cause side effects. The most common include nausea, bloating, and constipation (sometimes accompanied by abdominal pains).  This is because one of the ways weight loss injections help is by slowing down how fast the stomach and intestine empty, which contributes to a sense of early and more prolonged fullness after meals.

These symptoms are typically worse when starting treatment and for the first few days after moving up to a higher-dose pen. Most people (>95%) find them fairly easy to tolerate, particularly as they tend to improve over time. However, if they persist, it’s important to seek medical advice.

Am I suitable for The SemaPen Programme?

Wegovy and Mounjaro are approved for use in adults with a BMI of 30 or higher, although there are certain medical conditions that would make treatment inadvisable.

This BMI cut off is lowered to 27  for those who also have at least one weight-related condition.  Some examples include high blood pressure, type 2 diabetes, high cholesterol, sleep apnoea, gastro-oesophageal reflux, weight-related depression or joint pain.  We will ask you about this as part of the onboarding process.

People of certain ethnic origins (Asian, Black Afro-Caribbean, Arabs) are more prone to developing type 2 diabetes and cardiovascular complications of obesity at lower BMIs than Caucasians and this may be taken into account when deciding if you are suitable for treatment.

Complete our free, online medical questionnaire to determine whether you are suitable for the SemaPen programme.

Can I get it on the NHS?

Wegovy and Mounjaro have been approved for use by the NHS, but discussions are ongoing as to when they will become widely available.

In addition, NICE has recommended more stringent prescribing rules than those that apply to private patients, in that NHS patients must have a BMI greater than 35 and at least one weight-related medical condition such as type 2 diabetes* to receive NHS treatment.

It is only under exceptional circumstances that the NHS will prescribe the treatment to people with a BMI of 30-35, even if they do have medical conditions.
