<s>[INST] Can I benefit from bariatric surgery? What are the indications for this treatment? [/INST] According to the recommendations made by scientific societies, people with the following characteristics are candidates for bariatric surgery:

A BMI above 35 kg/m2 coupled with other major comorbidities such as type 2 diabetes, high blood pressure, sleep apnea, severe joint disease, etc.
The recommended age range is from 18–60 years, although surgery in people over 60 is increasingly common after a medical assessment and adequate preparation.
Patients with a serious organic disease (liver cirrhosis, severe heart disease) who may not be able to tolerate anaesthetic induction cannot undergo bariatric surgery.
In patients for whom non-surgical weight loss treatments have been unsuccessful.
No drug or alcohol addiction.
Incurable oncological disease.
Psychological stability, no severe mental illnesses or severe mental retardation.
The patient’s commitment to following postoperative treatment in order to guarantee long-term success (since it is a functional operation that alters the anatomy of the digestive system, it causes intestinal malabsorption with nutritional alterations and therefore the patient must adhere to long-term monitoring).
Realistic expectations regarding the results of the bariatric surgery. The patient must be aware that even though there are significant aesthetic benefits, they are not the aim of the surgery; nor is achieving an ideal weight.
Well-informed patients must be aware that it is a high-risk procedure because of the comorbidities associated with obesity, amongst other reasons.   Source: Clinic Barcelona.
