I am 21, I weigh 230 lbs, and I am 5'7". Am I qualified for a gastric sleeve?

At 21 years old, weighing 230 pounds, and standing at 5'7", your BMI is around 36, which is considered in the overweight to obese range. Weight loss surgery, including a gastric sleeve, is typically considered for individuals with a BMI over 35, especially if you have health conditions related to obesity, like diabetes, high blood pressure, or joint pain. If you have not been able to lose weight through diet and exercise or if your weight is affecting your health and quality of life, surgery might be a good option to consider.
Your age is on the younger side, but it's not uncommon for people in their 20s to qualify for bariatric surgery if they have struggled with long-term weight issues.

Hello, your BMI is 36. You are suitable for the gastric sleeve operation. The gastric sleeve operation is appropriate for the patients whose BMI value between 35-40; and in patients with a BMI value between 30-35, in case of severe diseases is appropriate. With this operation, existing diseases or possible weight-related diseases can be treated and prevented. Thus, a healthier life can be led by the gastric sleeve.

Thank you so much for your question.
You BMI is 36.0 kg/m2 I recommend Sleeve gastrectomy surgery, this permanently removes 80 percent of your stomach. The surgeon then sews the rest of the stomach into a small pouch or sleeve. I think this procedure will be really good for you, but remember to get an appointment with a health certified Surgeon that way you can evaluate all the available options and choose the one that works best for your particular case.
Hope that you can get all you need and want.
