How much does a medical weight loss treatment cost in Spain: complete 2026 guide

Introduction

If you are considering a medical weight loss treatment, you have probably run into a frustrating reality: it is extremely difficult to find out what it actually costs. Private service websites show partial prices, traditional clinics do not publish their fees, and public options are restricted to very specific patient profiles.

This article gives a transparent breakdown of every component of the cost of comprehensive medical weight loss treatment in Spain, with real ranges updated for 2026 for each type of service. The aim is to help you make an informed decision by comparing like with like. Information reviewed by Dr David Céspedes, Medical Director at AiON.

The real cost of untreated obesity

Before talking about what treatment costs, it is worth putting into perspective what not treating it costs. Obesity is not just a cosmetic matter: it is a medical condition associated with more than 200 conditions, from type 2 diabetes to ischaemic heart disease, sleep apnoea, osteoarthritis, fatty liver, infertility and several types of cancer.

The cumulative personal financial cost of living with obesity over the long term includes:

• Long-term medication for associated comorbidities (antihypertensives, lipid-lowering drugs, antidiabetic medication).
• Frequent medical appointments and diagnostic tests.
• Impact on work productivity and absenteeism.
• Clothing, adapted furniture, transport.
• Money spent over the years on diets, "miracle" products and gym memberships with no results.

A conservative estimate for someone living with obesity who does not treat it effectively puts the lifetime extra cost in the tens of thousands of euros, without counting the loss of quality of life and life expectancy.

Components of the cost of comprehensive medical treatment

A serious medical weight loss programme includes several components. To compare options properly, it helps to understand what each service does and does not include.

Initial medical consultation

A full patient assessment: medical history, examination, review of blood test results, assessment of contraindications, definition of treatment goals, informed consent. Usual duration: 30 to 60 minutes.

Follow-up consultations

Regular appointments (usually monthly during the first few months) to assess response, adjust doses if medication is involved, manage side effects and review weight and metabolic markers. Usual duration: 15 to 30 minutes.

Drug treatment where appropriate

If the doctor prescribes medication (GLP-1 agonists or other options), the cost is added separately to the consultation. The medicine is dispensed at a pharmacy with a prescription.

Personalised nutrition plan

Many serious medical programmes include a nutrition plan tailored to the patient and the treatment goal and, where medication is involved, a strategy for managing digestive side effects and maintaining muscle mass during the calorie deficit.

Complementary supplementation

During weight loss treatment with medication, specific supplementation is often recommended: magnesium (for cramps), protein (to preserve muscle mass), micronutrients (to compensate for lower food intake) and digestive support (to manage GI effects).

Ongoing follow-up and support

Access to additional consultations, answers to questions between appointments, adjustments between scheduled visits. Treatment with GLP-1 agonists without proper follow-up has very high dropout rates.

Option 1: the public health service

For patients with type 2 diabetes who meet the criteria in the Spanish National Health System's list of covered services, and specifically for glycaemic control, some GLP-1 agonists are funded.

Cost to the patient

• GP or endocrinology appointment: no direct cost.
• Medication: patient co-payment based on income level (usually 40% or 50% of the retail price, with monthly caps depending on pension status).

This is the cheapest option, but it comes with limitations: type 2 diabetes only and subject to criteria, public system waiting times, and no access to Wegovy or Mounjaro for the time being.

Option 2: private face-to-face consultation with an endocrinologist

The traditional private medicine model. The patient attends an in-person appointment with an endocrinologist or an internal medicine specialist trained in obesity.

Typical cost

• Initial consultation: 120 to 300 euros (varies widely depending on city, clinic and specialist).
• Follow-up consultations: 80 to 200 euros per visit, usually once or twice a month at the start.
• Medication at a private pharmacy: 120 to 300 euros a month depending on the drug and dose.
• Blood tests if the doctor requests them: 60 to 200 euros extra depending on the tests.

Estimated total monthly cost during the active phase: 280 to 700 euros.

Option 3: premium clinics with a full programme

Private clinic models offering comprehensive programmes that include consultations, medication, a nutrition plan, follow-up and sometimes additional services (psychology, dietitian, personal training).

Typical cost

• All-inclusive monthly packages: 300 to 700 euros a month depending on the clinic.
• Some clinics charge for medication separately.
• Minimum commitment is usually 3 to 6 months.

Typical total monthly cost: 350 to 800 euros.

Option 4: reputable private telemedicine

An emerging model that combines online assessment and follow-up with a registered doctor, issuing of a private electronic prescription and dispensing of the medicine at the patient's usual pharmacy.

Typical cost

• Monthly medical protocol (includes initial assessment, consultations, follow-up, prescription and support): 99 to 200 euros a month depending on the service.
• Medication at the pharmacy: 120 to 300 euros a month depending on the drug and dose.

Estimated total monthly cost: 220 to 500 euros.

Important: within this model there are reputable services and there are dubious ones. See the criteria in the next section.

What to look for: value for money and criteria for choosing

Price should not be the only criterion. In medicine, paying little for an inadequate service works out infinitely more expensive than paying a fair price for a proper one. The factors to weigh up:

An identifiable, verifiable prescribing doctor

If the service does not clearly show who the doctor is, with a verifiable medical registration number, that is a warning sign. Reputable services identify the prescriber in full.

A genuine clinical assessment

A prescription after a five-minute questionnaire with no real medical interaction: an absolute red flag. A genuine clinical assessment with medical history, blood tests and a video consultation with the doctor: correct.

Follow-up included

Treatment with GLP-1 agonists without medical follow-up is incomplete. Side effects, dose adjustments and gradual titration all require supervision. If a service does not clearly include it, something is missing.

Accessible support

Can you get an answer at three in the morning if a side effect worries you? Reputable services have accessible support channels.

Price transparency

Itemised, clear prices, no small print, no hidden charges. A no-charge policy if you are not clinically suitable.

Clinical transparency

An honest explanation of contraindications, expected side effects, how long treatment lasts and what happens after stopping it.

Red flags on prices and suspicious offers

• Prices well below the market rate (for example, "Ozempic for 50 euros a month").
• Aggressive discount offers that create artificial urgency.
• Promises of guaranteed results ("lose 20 kg in 3 months or your money back").
• Services asking for payment by bank transfer or cryptocurrency without an official invoice.
• Services with no identifiable specialist but a generic "medical team".
• Services that dodge verification of medical registration.

Summary comparison of the options

To sum up, these are the usual total monthly cost ranges by type of service, including medication except where stated:

• Public health service (type 2 diabetes only, subject to criteria): very low cost, around 5 to 50 euros a month in co-payment.
• Traditional private face-to-face consultation: 280 to 700 euros a month during the active phase.
• Premium clinics, full package: 350 to 800 euros a month.
• Reputable private telemedicine: 220 to 500 euros a month.
• Unregulated online services: apparently cheaper, but with considerable health and legal risk.

Conclusion

The real cost of comprehensive medical weight loss treatment in Spain ranges from 220 to 800 euros a month during the active phase, depending on the service model and whether medication is included. Cases funded by the public health service are exceptional and limited to type 2 diabetes meeting specific criteria.

Paying less does not always mean better value for money. In medicine, a genuine clinical assessment, ongoing follow-up and accessible support are the components that determine how effective and safe treatment is. Choosing on price alone can turn out to be the most expensive decision in the medium term if the service is inadequate.

The clinical recommendation is to apply rigorous quality criteria, verify the doctor's identity and medical registration, insist on a genuine clinical assessment and ongoing follow-up, and be consistently wary of prices that look too good to be true.

Frequently asked questions

How much does Ozempic cost privately in Spain?

Between 120 and 200 euros a month depending on the dose, with a private prescription and dispensed at a pharmacy. On top of this you need to add the cost of the medical consultation that issues the prescription.

How much does Mounjaro cost privately in Spain?

Between 180 and 300 euros a month depending on the dose, with a private prescription and dispensed at a pharmacy. It is not currently funded by the Spanish public health system.

Is face-to-face or online treatment cheaper?

In general, reputable private telemedicine tends to offer better value for money than a traditional private face-to-face consultation, because it bundles all the services into a monthly protocol with no charge per visit.

Does private health insurance cover obesity treatment?

It depends on the insurer and the policy. Most private insurers in Spain cover an appointment with an endocrinologist, but they do not cover medication or specific weight loss programmes. Check the specific terms of your policy.

Why is there such a big price difference between services?

Because they include different things. A service that includes consultations, follow-up, a nutrition plan and ongoing support has higher running costs than one that simply sells a one-off appointment. The key is to compare what each service includes, not just the price.

Your next step

Comparing prices only makes sense if you are comparing like with like: what assessment sits behind it, who prescribes and what follow-up is included. Medical weight loss treatment is now available in Spain with a prior assessment, a prescription where appropriate from a registered doctor and ongoing follow-up from the medical team. You can check whether you are eligible in 30 seconds.
