Saxenda Before and After

Saxenda is a weight loss medicine that contains the active substance liraglutide.

Saxenda-Weight-Loss Pen-UK, Saxenda Weight Loss Pen-UKHere are a few considerations about Saxenda before and after taking the medication.

It is similar to a natural occurring hormone called glucagon-like peptide-1 (GLP-1 ) that is released from the intestine after a meal. 

Saxenda® works by acting on receptors in the brain that control your appetite, causing you to feel fuller and less hungry.

This may help you eat less food and reduce your body weight.

If you need to lose a little weight and you've read about 'the skinny injection pen' then you may have been sucked into hype and need to be very, very careful.

Saxenda injections are unlikely the best option for you if your Body Mass Index (BMI) is less than 27. Speak to your doctor if your BMI is over 27 and you have a weight related medical condition OR you're living with obesity (have a BMI over 30) and have tried and failed at calorie controlled diets before… then this weight loss supporting injection may be the right next step for you (2).

Saxenda UK injections are not a miracle cure (though we wish it was). Saxenda injection pens are a tool which should be used alongside a calorie deficit diet and a doctor approved exercise program.

This is why we'll send you an access code to the Liva Healthcare app when you buy from us so you can track and monitor your health and lifestyle goals. You'll also have access to a Liva health coach to ask questions within the app.
