Hello, Thank you for your question. First of all, I respect your concern and desire to lose weight and improve your health. With a BMI of 25, you technically just meet the World Health Organization (WHO) classification of "overweight." Being overweight increase your risk of obesity-related co-morbidities such as type II diabetes (T2DM), hypertension, sleep apnea and other respiratory disorders, non-alcoholic fatty liver disease, osteoarthritis, lipid abnormalities, gastrointestinal disorders, and heart disease. Thus you are wise to be concerned about your weight, its impact on your health, and the increased difficulty to lose weight or undergo surgery as you grow older. That being said, a BMI of 25 means you are not a candidate for the sleeve gastrectomy. To qualify for weight loss surgery, the American Society for Metabolic and Bariatric Surgery recommends you meet one of the following: BMI ≥ 40, or more than 100 pounds overweight.BMI ≥35 and at least one or more obesity-related co-morbidities such as type II diabetes (T2DM), hypertension, sleep apnea and other respiratory disorders, non-alcoholic fatty liver disease, osteoarthritis, lipid abnormalities, gastrointestinal disorders, or heart disease.Inability to achieve a healthy weight loss sustained for a period of time with prior weight loss efforts. As Dr. Alvarez pointed out, safe surgeons in Mexico (and elsewhere) follow the same or very similar guidelines. Even gastric balloons are usually limited to individuals with a BMI >35 or >30 with certain comorbidities. I would also like to point out that the BMI is an imperfect measure. For example, persons with higher than normal muscle mass may have a BMI in the overweight or obese category, when in fact they are neither. On the flip side, a person who has a small frame and little muscle mass, may actually be overweight at a BMI under 25. Consultation with a physician can help you determine you ideal body weight. If you find you are at a healthy weight, but are still unhappy with your body shape or size, you may be an appropriate candidate for cosmetic surgery. Kindest regards, Dr. Moein
