Gastric sleeve surgery (also known as sleeve gastrectomy) is a surgical method used in the treatment of obesity. Below are listed some situations and candidates for whom gastric sleeve surgery may be considered:

1. Individuals with a BMI of 40 or higher: Gastric sleeve surgery is typically used for individuals who are severely obese, with a BMI of 40 or higher. BMI is an index that calculates your body weight in kilograms divided by the square of your height in meters.

2. Individuals with a BMI between 35-39.9: Gastric sleeve surgery may be considered for individuals with a BMI between 35-39.9. In this case, the presence of obesity-related health issues (such as type 2 diabetes, high blood pressure, sleep apnea, etc.) and the ineffectiveness of other weight loss methods are also taken into account.

3. Individuals with obesity-related health problems: Gastric sleeve surgery may be performed to control or improve health problems related to obesity. In this case, obesity-related health issues may include conditions such as type 2 diabetes, high blood pressure, sleep apnea, heart disease, joint problems, and metabolic syndrome, among others.

4. Cases where other weight loss methods have failed: Gastric sleeve surgery may be considered when conservative weight loss methods like diet, exercise, and lifestyle changes have proven ineffective. This surgery has the potential to achieve long-term success by providing sustainable weight loss.

In any case, it is important for an expert to evaluate individuals for gastric sleeve surgery. During this assessment process, factors such as the individual’s level of obesity, health status, weight loss attempts, and the potential benefits and risks of the surgery are taken into consideration. The decision for surgery should be personalized based on the individual’s specific situation.
