Prerequisites for bariatric surgery

An operation to reduce overweight is always a relevant interference in the anatomy and physiology and can have significant influence on digestion and the support with relevant vitamins and trace elements. Along with it comes the risk always inherent with major surgery. Therefore, a surgical solution should never be considered as first option. Only if all other ways of conservative treatment failed, an operation should be taken into account.

Beside the medical criteria for bariatric surgery, there are other prerequisites that have to be fulfilled, in order to get cost-coverage from the insurance.


  • You are between 18 and 65 years old.
  • Your BMI is higher than 40 kg/m²
    or your BMI is higher than 35
    You're suffering form side-diseases as diabetes, joint complaints, heart problems, sleep apnea, dyspnea
  • You're obese for more than 5 years
  • A mulit-level-strategy effort in conservative therapy has failed
  • You don't have any other curable disease that causes or contributes to obesity
  • You're willing to change your life-style and nutritional behavior completely and take advantage of a life-long follow-up programm
  • You're not addicted to alcohol or drugs

The three columsn of conservative treatment

For a sufficent conservative treatment, there must be elements of the three main columns physical exercise, nutritional behavior and change of life style. The therapy-approaches from that three aspects must take place in a concerted way and can be supported by medical treatment.

Each therapy not consisting of those aspect must be considered inadequate.


In order to proof a fully covered conservative treatment approach, you may need several documents. A great help for us are copies we can attach to your file and later to the cost-application. You may need:

  • A letter from your general pyhsician describing the conservative therapy that took place
  • Certificate from Weight Watchers
  • Medical report from diet clinics or rehabs.
  • Reports from medical treatment
  • Reports from nutritional counselling
  • Memberships in fitness-clubs
