Frequently asked questions

Below we list the most frequently asked questions about our service. If you have other questions or concerns, please contact us and we will help you.

Which medications do you use for weight loss?

We usually use the very latest type of medication, known as GLP-1 analogues, but the doctor always makes an individual assessment to determine which treatment is best suited for each individual.

Do I have to take medication for my obesity for the rest of my life?

Obesity is a chronic disease. Unfortunately, when you remove the drug, you are often back where you were before you started and the body starts striving for its highest weight again. It is not dangerous to stop taking the medication and then start again if you notice that you begin to gain weight. With lifestyle changes such as an increase in exercise and a different diet some may achieve an energy balance after reaching a healthy weight, and may therefore not need to go back on the medication.

Who can receive medication for overweight/obesity?

Many different types of anti-obesity medicines have been tested in clinical trials. These medications are recommended for use in cases of obesity (BMI ≥ 30 kg/m2) or overweight (BMI ≥ 27 kg/m2) with complications or risk factors present.

These risk factors may include high blood pressure, elevated blood lipids, elevated blood sugar, atherosclerosis, or sleep apnea syndrome.

Medications can also be used to maintain weight loss, for example, in individuals who were previously severely overweight and have successfully lost weight through methods like dieting or weight loss surgery.

What side effects may I experience?

Because it is the body's own hormone that is used, which has only been modified to slow down its breakdown, the side effects are few and mild. In the larger studies that have been conducted, the side effects are relatively similar between  test groups taking placebo and test groups taking medicine. Side effects are most common at the beginning of treatment, which is why the initial dose is low and increased slowly.

You may experience nausea, gas, and diarrhoea, mild gastritis, or constipation, but with the support of a dietitian, most symptoms can usually be avoided.

Customer testimonials

Great people and great results

Michael Mc grath

Agile app & communication. All doctors have some form of "interest" in obesity, which means that you get a doctor who is knowledgeable and involved in obesity. Compared to regular care. That just says you need to move more.


The experience so far has been great! A lot of support from different experts, especially the doctor and the trainer :)

Marta Dragovic

Everything has gone very quickly & smoothly. Good effect of the product, feel much less hunger & lost 5 kg in 4 weeks. Very nice doctors & coaches who respond quickly & explain in a way that is easy to understand.


I had a great experience speaking with the doctors on Yazen. They responded very helpfully to all my questions and concerns. The results of the testing came quickly and everything was really efficient. I would recommend this service.
