Rethinking Obesity Care Through a Comprehensive Digital Model

By combining multidisciplinary expertise with high accessibility and ongoing patient interaction, the model aims to support sustainable obesity treatment and long-term health improvement.

Examining the effectiveness of a new digital care model on weight loss for people living with obesity

This real-world evaluation of more than 2,600 patients in Sweden showed that Yazen’s comprehensive digital obesity care model achieved 12.6% weight loss after 6 months, alongside significant improvements in cardiometabolic health markers. The model combines GLP-1 treatment, lifestyle intervention, and continuous multidisciplinary support through a digital platform designed for long-term obesity care.

High Adherence to GLP-1 Receptor Agonists: 18-Month Outcomes from the Yazen Model

High adherence rates to GLP-1 receptor agonists within a structured, digitally based weight management programme, may contribute to improved long-term medication adherence.

This real-world analysis from Yazens first large scale operational quality follow-up, demonstrates almost 70% compliance with GLP-1 medications at 12 months, surpassing earlier studies that showed 20-50%1-4. After 2 years*, 60% of patients were still in treatment.

High-Volume Patient–Caregiver Interactions in a Fully Digital Obesity Care Model

Digital obesity care enables high levels of patient–caregiver interaction and sustained engagement in treatment, with higher retention than in other settings, potentially supporting longterm outcomes.

Across three years, messages exchanged, weight entries logged and retention in treatment was quantified for more than 50,000 patients.

Contraceptives and weight loss medications: How Wegovy and Mounjaro can affect the efficacy of birth control pills

When treating with weight loss medications like Wegovy (semaglutide) and Mounjaro (tirzepatide), it is important to consider how the medications can affect fertility and the efficacy of contraceptives. Medications such as semaglutide (Ozempic, Wegovy, Rybelsus) and tirzepatide (Mounjaro) can contribute to improved fertility in women with obesity, partly as a result of weight loss and improved hormonal and metabolic function. At the same time, they can affect the absorption and efficacy of oral contraceptives.

Risks of using weight loss medications without medical guidance

The demand for medical treatment of obesity and overweight has increased significantly in recent times, which in turn has contributed to the emergence of a market where medicines are sometimes distributed outside established and regulated healthcare systems. Using these medications without a doctor's prescription, and without structured and continuous follow-up, entails significant medical risks.

Medical weight loss – how the treatment works

Managing overweight is rarely a matter of willpower. The body's complex biological systems interact to regulate appetite, energy expenditure, and fat storage – often in a way that counteracts weight loss. Medical weight loss aims to influence these processes and create better conditions for sustainable results over time. Here, we go through how the medications work and who the treatment is suitable for.

Weight gain after GLP-1 treatment – how to maintain weight loss long-term

Weight gain after stopping GLP-1 medication is common and is partly due to appetite regulation, hunger, and energy balance gradually returning to previous levels when treatment ends. Obesity is a chronic and complex disease where biological mechanisms affect hunger, satiety, and body weight over time.

Why am I not losing weight with hypothyroidism?

Losing weight with hypothyroidism can be perceived as more difficult, even with healthy lifestyle habits. An underactive thyroid means lower levels of hormones that regulate metabolism, which can affect energy expenditure and stamina. However, the effect on body weight is usually moderate and varies between individuals. When hypothyroidism is treated and hormone levels normalize, the conditions for weight loss improve.

Lipedema or obesity – how can you tell the difference?

Understanding why the body does not always respond as expected to diet and physical activity is an important starting point for the right treatment. Lipedema and overweight can in some cases resemble each other, but are two different conditions with distinct underlying mechanisms. They can also occur simultaneously, which can further complicate the clinical picture.
