Wegovy in Barcelona: Weight Loss with Comprehensive Support

Wegovy: The Semaglutide Formulation Designed to Treat Obesity

Wegovy is the brand name for semaglutide in a specific formulation and dosage for the treatment of obesity and overweight with comorbidities. The molecule is the same as Ozempic, but the indication and dosing schedule are different: while Ozempic is primarily authorized for type 2 diabetes, Wegovy is designed and authorized for medically supervised weight loss.

It is a highly effective drug, with solid clinical data in patients with obesity. But its responsible use requires three things: correct indication, progressive dose titration, and medical-nutritional support. At Santé Clinics, we integrate all three elements into a unique protocol. This article explains what it is, how it works, for whom it is indicated, and how we implement it.

What is Wegovy and How Does it Work?

Wegovy is semaglutide, a GLP-1 receptor agonist. It mimics the action of glucagon-like peptide-1, a natural intestinal hormone that the body releases after eating. By activating the GLP-1 receptor:

• Increases feelings of fullness through signaling in the hypothalamus and brainstem.
• Slows gastric emptying: meals "feel fuller" for longer.
• Stimulates glucose-dependent insulin secretion.
• Reduces glucagon secretion.
• Decreases appetite and cravings, including the "hedonic" or impulsive component of eating.

The net effect is a significant reduction in spontaneous caloric intake and, with it, clinically significant weight loss.

It is administered by subcutaneous injection once a week, with progressive dose titration over several weeks to improve digestive tolerance.

Documented Benefits

In the pivotal STEP-1 trial and subsequent studies, obese patients treated with semaglutide 2.4 mg weekly plus lifestyle intervention achieved average weight losses of around 15% of body weight at 68 weeks, with significant percentages of patients achieving >20%. Beyond weight:

• Improvement in glycemic profile (in patients with prediabetes and type 2 diabetes).
• Improvement in lipid profile.
• Reduction in blood pressure.
• Improvement in liver markers and quality of life.
• Reduction in cardiovascular risk in high-risk populations, according to specific studies.

Benefits depend on adherence, tolerated dose, and, above all, nutritional and exercise support.

Indications

Wegovy is indicated, in its main regulatory approvals, for adults with:

• Obesity (BMI ≥30).
• Overweight (BMI ≥27) with at least one associated comorbidity (hypertension, dyslipidemia, type 2 diabetes, obstructive sleep apnea, established cardiovascular disease).

In conjunction with a hypocaloric diet and increased physical activity. The latter is not merely decorative; the drug was approved alongside lifestyle changes, not as a standalone treatment.

Not indicated:

• In patients with normal weight or overweight without comorbidities.
• As an aesthetic treatment for "definition" or losing the last few pounds.
• Pregnancy, lactation, short-term pregnancy planning.
• Personal or family history of medullary thyroid carcinoma or MEN-2.
• History of severe pancreatitis.
• Severe eating disorders without coordination with mental health.
• Hypersensitivity to the active substance.

Common Side Effects

The most frequent are digestive and, for the most part, dose-dependent and reversible:

• Nausea (in the first few weeks and when increasing dose).
• Diarrhea, constipation.
• Fullness, reflux, belching.
• Mild abdominal pain.
• Headache, transient fatigue.
• Decreased appetite (desired effect, but it is important to ensure adequate protein and micronutrient intake).

They usually improve with appropriate titration and nutritional adjustments.

Less frequent but relevant adverse events:

• Acute pancreatitis: in case of severe abdominal pain, discontinue and consult a doctor.
• Cholelithiasis and biliary disease.
• Hypoglycemia if combined with insulin or sulfonylureas.
• Allergic reactions.
• Transient worsening of retinopathy in diabetes with poor prior glycemic control.

Wegovy Protocol at Santé Clinics

1. Initial medical consultation: complete medical history, personal and family history, medication, comorbidities, examination, blood pressure, BMI, abdominal circumference, recent or requested lab tests.
2. Assessment of indication and exclusion of contraindications.
3. Nutrition consultation (mandatory): plan design, protein intake, digestive management, hydration, exercise plan.
4. Initiation of treatment with progressive weekly titration according to clinical guidelines.
5. Monthly follow-up in the initial phases (tolerance, dose adjustment, weight evolution, body composition with bioimpedance).
6. Coordination with body aesthetics treatments if sagging or redistribution appears (HIFU, INDIBA, mesotherapy, collagen stimulators).
7. Maintenance plan and periodic re-evaluation.

The Inevitable Question: Is it Forever?

Obesity is a chronic disease with a biological basis. This means that many patients require ongoing treatment, just like a patient with hypertension or dyslipidemia.

Some patients:

• May maintain results after discontinuing the drug if they have consolidated habits.
• Require indefinite low-dose maintenance.
• Require treatment cycles.

This is decided by evolution, not a fixed expectation. What is a rule: discontinuing the drug without having worked on nutrition and exercise is associated with weight regain.

Wegovy vs Ozempic vs Mounjaro

• Ozempic: semaglutide, primary indication type 2 diabetes.
• Wegovy: semaglutide in specific formulation and dose for obesity.
• Mounjaro / Zepbound: tirzepatide, dual GIP/GLP-1 agonist.

The choice is made by the doctor based on the patient, indication, comorbidities, availability, and response. It is not "better or worse" in the abstract.

What GLP-1 Alone Does Not Do

• It does not build muscle mass: protein + strength training does.
• It does not teach habits: the nutritionist and time do.
• It does not correct sagging that may appear with significant weight loss: body aesthetics treatments are for that.

Frequently Asked Questions

Is Wegovy the same as Ozempic? The active ingredient is the same (semaglutide), but the formulation, dosage, and official indication are different. Wegovy is specifically designed to treat obesity.

Is the medical consultation to assess treatment free? No. It is a specialized medical consultation with its cost; we will confirm it when you book.

How much weight is lost with Wegovy? In pivotal studies, around 15% of body weight at 68 weeks with maximum dose and lifestyle support, with variability per patient.

Do I have to inject myself? Yes, it is a weekly subcutaneous autoinjector pen that the patient learns to use.

What if I tolerate it poorly? Titration is adjusted to the patient. Nutritional strategies exist, and if necessary, other medications can be considered.

Do I need to exercise? It is highly recommended. Strength training is essential to preserve muscle mass during weight loss.

The first step is not the injection. It is an honest medical consultation to decide if it is the right tool for you and, if so, integrate it into a plan that combines nutrition, exercise, and, when appropriate, body aesthetics treatments.
