Weight loss & health
Doctor vs. nutritionist — which is right for you?
A common question: "I want to lose weight — who should I see?" The answer depends on your health, medications and goal. Here's a clear comparison of where the line falls and what each specialist may do.
Doctor (family medicine / preventive medicine)
- • Orders and interprets all lab tests
- • Prescribes and adjusts medication (incl. GLP-1, metformin, statins)
- • Diagnoses insulin resistance, PCOS, thyroid disorders
- • Is responsible for medical decisions
Nutritionist
- • Builds menus and recipes
- • Behavioral support and journaling
- • Shopping lists, food diary, habits
- • Doesn't interpret labs or prescribe medication

Frequently asked questions
Do I need to see a doctor first?
If you take medication, have a chronic condition, want to lose more than 3 kg, or suspect a metabolic issue (fatigue, appetite control, salty-food cravings at night) — yes. Meal-planning and gym nutrition questions for a healthy person can go straight to a nutritionist.
Who is allowed to prescribe GLP-1 (Ozempic, Wegovy, Mounjaro) in Estonia?
Only a doctor. A nutritionist may not prescribe or dose medication, including weight-loss drugs.
Does the doctor also give me a menu?
During the consultation we give nutritional direction (e.g. lower-carb, Mediterranean, time-restricted eating) and practical examples, but we don't build a detailed weekly menu. For that we refer you to partners.
