Obesity Treatment – A Personalized Medical Approach to Weight Management

Modern obesity treatment combining professional medical assessment, individually tailored therapy, and continuous monitoring of progress.

Excess body weight is not always simply the result of dietary habits and insufficient physical activity. Weight regulation is influenced by numerous factors, including genetics, hormonal and metabolic processes, certain medical conditions, medications, sleep, and lifestyle habits.

Obesity is a chronic, complex, and often progressive disease that can increase the risk of developing type 2 diabetes, high blood pressure, cardiovascular disease, fatty liver disease, and other health complications.

That is why successful obesity treatment requires more than short-term diets and restrictive eating plans.

At DEA Clinic in Zagreb, our approach to weight management is based on an individualized medical assessment, identification of health risks, and development of an appropriate treatment plan, with ongoing monitoring of progress.

The goal is not simply to lose weight, but to improve metabolic health, preserve muscle mass, and achieve sustainable long-term results.

What Is Obesity and Why Does It Require a Medical Approach?

Obesity is a chronic disease characterized by excessive accumulation of body fat that can negatively affect health.

Body mass index (BMI), calculated using body weight and height, is commonly used as an initial indicator of weight status.

BMI is a useful screening tool, but it does not provide a complete picture of a person's health. It does not distinguish between fat and muscle tissue or indicate how body fat is distributed.

For this reason, risk assessment also takes into account waist circumference, associated medical conditions, metabolic indicators, and individual patient characteristics.

Why Do Some People Struggle to Lose Weight and Maintain Their Results?

Weight regulation is a complex process involving hormones, the nervous system, metabolism, and the mechanisms that control hunger and satiety.

After weight loss, the body may respond with increased hunger and changes in energy expenditure, making it more difficult to maintain the results achieved.

Factors that may contribute to the development and persistence of obesity include:

• Genetic predisposition and family history.

• Hormonal and metabolic factors.

• Disorders affecting appetite regulation and satiety.

• Certain chronic diseases and medications.

• Insufficient sleep, stress, and lifestyle habits.

• Environmental and other factors influencing eating behavior.

Therefore, treatment should not be based on universal diets, but rather on understanding each patient's individual health needs.

What Does the Obesity Treatment Process Look Like at DEA Clinic?

01. Initial Consultation and Medical Assessment

The first step in obesity treatment is a comprehensive assessment of your health.

During the consultation, the doctor gathers information about your weight history, previous weight-loss attempts, existing medical conditions, medications, and dietary and lifestyle habits.

The assessment may include:

• Measuring body weight and height and calculating BMI.
• Measuring waist circumference and assessing body fat distribution.
• Evaluating cardiometabolic risk factors.
• Reviewing dietary habits, sleep, and physical activity.
• Examining existing medical records and current medications.

02. Laboratory and Metabolic Assessment

Based on the doctor's individual assessment, laboratory tests may be recommended to evaluate metabolic health and identify potential associated conditions.

These may include blood glucose and HbA1c measurements, lipid profiles, liver enzymes, and other relevant indicators as needed.

Hormonal testing, including thyroid function assessment, is performed when medically indicated.

The results are used to develop a treatment plan tailored to the patient's health condition.

03. Developing a Personalized Treatment Plan

Once the assessment is complete, an appropriate treatment approach is selected.

This may include dietary modifications, adjustments to physical activity, support for lifestyle changes, and, when medically indicated, pharmacological obesity treatment.

The plan is tailored to the patient's initial body weight, health risks, associated medical conditions, and realistically achievable goals.

04. Continuous Monitoring and Treatment Adjustments

Obesity treatment is not a one-time procedure.

During follow-up appointments, changes in body weight and waist circumference, health indicators, treatment tolerability, and progress in adopting sustainable habits are monitored.

The doctor adjusts the treatment and ongoing care plan when necessary.

Modern Pharmacological Obesity Treatment – GLP-1 Therapy

Advances in medicine have enabled the development of medications that target the biological mechanisms responsible for appetite regulation, satiety, and food intake.

Modern obesity treatment options include medications that act on glucagon-like peptide-1 (GLP-1) receptors, as well as medications with combined activity on GIP and GLP-1 receptors.

These therapies may play an important role in the treatment of patients for whom lifestyle changes have not resulted in satisfactory weight loss or who have additional obesity-related health risks.

What Is GLP-1 and How Does It Work?

GLP-1 (glucagon-like peptide-1) is a naturally occurring hormone released in the digestive system after eating. It plays a role in regulating appetite, satiety, and glucose metabolism.

Medications that mimic its effects may:

• Reduce hunger and the desire to eat.
• Prolong feelings of fullness after meals.
• Slow gastric emptying.
• Help control food intake.
• Support weight loss and long-term weight management.

Unlike short-term diets, pharmacological therapy targets specific physiological mechanisms involved in body weight regulation.

However, medications are not a substitute for a balanced diet, physical activity, and long-term lifestyle changes. Instead, they are used as part of a comprehensive treatment plan.

Who May Be a Candidate for GLP-1 Therapy?

In adults, pharmacological obesity treatment with certain approved medications may be considered when the following criteria are met:

• A BMI of 30 kg/m² or higher.
• A BMI of 27 kg/m² or higher, with at least one weight-related medical condition, such as high blood pressure, dyslipidemia, prediabetes, or type 2 diabetes.

These are general eligibility criteria for certain medications approved for weight management.

The final treatment decision depends on the approved indications of the specific medication, the patient's health condition, and the doctor's clinical assessment.

How Is GLP-1 Therapy Administered?

Before starting treatment, the doctor determines whether there are appropriate indications for the medication and evaluates possible contraindications and risk factors.

If treatment is initiated, the dosage is adjusted according to the selected medication and individual tolerability.

With many therapies, the dose is gradually increased to reduce the frequency and severity of gastrointestinal side effects.

Throughout treatment, it is important to monitor changes in body weight, dietary habits, hydration, potential side effects, and overall health.

Possible Side Effects of GLP-1 Therapy

The most common side effects of certain GLP-1 medications include nausea, vomiting, diarrhea, constipation, and abdominal discomfort.

Less commonly, more serious complications may occur, including acute pancreatitis or gallbladder problems. The risk of dehydration due to significant gastrointestinal symptoms must also be considered.

Certain medications are not suitable during pregnancy, and planning a pregnancy may require discontinuing treatment in advance, according to the instructions for the specific medication.

For these reasons, pharmacological obesity treatment should only be conducted under medical supervision.

How Much Weight Can You Lose With Medically Supervised Weight Management?

Treatment results vary from person to person and depend on initial body weight, associated medical conditions, selected therapy, dietary habits, physical activity, and individual response.

Clinical studies of certain modern medications have demonstrated significant average reductions in body weight. However, these results are not the same for every patient and do not guarantee an individual outcome.

For example, one large clinical trial of semaglutide reported an average body weight reduction of approximately 15% after 68 weeks, alongside dietary changes and increased physical activity.

Even moderate weight loss can have beneficial effects on certain metabolic indicators and health risks.

The goal of treatment is not to achieve the fastest possible weight loss, but rather a medically meaningful and sustainable long-term reduction in body weight.

Why Is Preserving Muscle Mass Important During Weight Loss?

Weight loss does not involve the loss of fat tissue alone. Some of the weight lost may come from lean body mass, including muscle tissue.

For this reason, a comprehensive obesity treatment program should include adequate protein intake, physical activity adapted to the patient's health condition, and strength training whenever possible.

Preserving muscle mass is important for physical function, strength, metabolic health, and overall quality of life.

Long-Term Weight Maintenance

Obesity is a chronic disease that often requires long-term monitoring and treatment.

Following significant weight loss, physiological adaptations may occur that increase hunger and make maintaining the achieved results more difficult.

Therefore, completing the initial weight-loss phase does not necessarily mean that treatment has ended.

A long-term weight maintenance plan may include continuing medically indicated therapy, regular check-ups, adjustments to dietary habits and physical activity, and ongoing monitoring of metabolic health.
