Medically supervised weight loss: how it works and what to expect

Losing weight safely starts with understanding why. See how a medically supervised weight-loss plan works, step by step.

Quick answer

A medically supervised weight-loss plan starts with a consultation and, when appropriate, lab tests. The doctor then sets a personalised plan (diet, physical activity and, if appropriate, medication) and follows your progress in regular visits. The pace of weight loss varies from person to person.

Why medical supervision

Excess weight can be linked to hormonal or metabolic factors, medication, sleep or stress. A medical assessment helps identify these factors, choose the right approach and monitor your health throughout.

How it works at Mya

  1. First consultation: history, habits, goals and measurements.
  2. Lab tests, when appropriate.
  3. Personalised plan with realistic goals.
  4. Follow-up visits to adjust the plan.

What about weight-loss medication?

Some medicines may be appropriate in specific situations. They are prescription-only, with their own indications, contraindications and side effects, and only the doctor can decide whether they suit you after the assessment.

What about bariatric surgery?

Bariatric surgery is an option for specific cases of obesity, decided by specialised surgical teams. Mya does not perform surgery; if the assessment justifies it, the doctor refers you to the right specialist.

Frequently asked questions

How many kilos will I lose?

Numbers cannot be promised. The doctor sets realistic goals and follows your progress with you.

Do I need lab tests?

In most cases yes, to know your starting point and adjust the plan safely.

How often are the visits?

Frequency is set in the plan, according to your progress.

Can I combine it with body treatments?

In some cases, yes. The doctor explains what makes sense at each stage.

Take the first step with an assessment

At the consultation, the doctor examines you, explains the options and tells you clearly what is and is not suitable in your case.
