According to the most recent standardizations of the International Federations of Bariatric Surgery, the surgery is indicated to:

• Patients with BMI greater than or equal to 40 kg/m2
• Patients with BMI between 35 kg/m2 and 39.9 kg/m2 with obesity-associated comorbidities (hypertension, diabetes, osteoarticular involvement, dyslipidemias, ventilatory and circulatory disorders, and others) who have already had previous unsuccessful conservative treatment.
• Patients over 18 years or patients who reached sexual and bone maturity.

However, individualized clinical evaluations should be mandatory in order to assess each case.
