How much do you have to be overweight to have the gastric sleeve and can it be done if you have acid reflux?

Hello,
Thank you for your question and congratulations on seeking proactive solutions to improve your health! For you to qualify to have laparoscopic sleeve gastrectomy surgery, the basic recommendation is determination of your Body Mass Index.  This number is calculated from your Height and weight.   To find your BMI - please refer to a BMI Calculator on any website.  The recommendation for Laparoscopic gastric bypass, Gastric Sleeve is BMI of 40 or greater.  If you are between 35 - 40 you can still qualify but you must have an obesity-related medical condition ( also know as co-morbidity).  These are often specific for most insurance companies, but the typical ones that are considered are:  Type II Diabetes, Hypertension, Obstructive sleep apnea, hypercholesterolemia.     Just to clarify this further the above numbers applies to an individual who is interested in having the cost of surgery covered by insurance. There are folks that fall outside these parameters. These individuals may still qualify for bariatric surgery but insurance will not cover their care. If your BMI is between 30 to 35, you still qualify for Laparoscopic gastric banding and Laparoscopic Sleeve gastrectomy but these procedures are not deemed as medically necessary and therefore you have to pay out of pocket.  The average cost of surgery is from 10k to 14k.  Each individual has specific circumstance that a simple number such as BMI can not represent.  Therefore the most suitable recommendation should come from your bariatric surgeon after a clear understanding of your goals, medical conditions and circumstances.   
A Skype or in person evaluation will allow the surgeon to give you an individualized   recommendation based on your unique situation and health goals.

Weight and height is not the only parameter to take into account for bariatric surgery. Also it is consider if you have other medical problems associated (glucose intolerance, insulin resistance, diabetes mellitus, high blood pressure, dyslipidemia, etc.), body composition ( body fat percentage above 30% for women). Recent studies have shown that a men with more than 20% of body fat or a women with more than 30% with normal weight have a high degree of metabolic imbalance they are still at high risk of developing metabolic syndrome, diabetes mellitus, insulin resistance, dyslipidemia, cardiometabolic disorders etc. with a higher risk or mortality. So each case has to be asses individually.Acid reflux is not an absolute contraindication for gastric sleeve. Acid reflux has a variety of causes, it could go from habits, type of food you eat, increase intrabdominal pressure, esophageal disfunction, slow gastric emptying or hiatal hernia. This last one can be and has to be corrected during the surgery, the gastric emptying will improve after the sleeve and the intrabdominal pressure will decrease as you loose weight. So each patient is different and it has to be asses individually

Thank you for your question,
People who have a body mass index of 35 to 40 kg/m² are  eligible if they have co-morbidities including diabetes, hypertension or sleep apnea. Non-surgical treatment modalities such as intragastric balloon or gastric botulinum toxin injections should be preferred in patients with a BMI less than 35 kg/m², however a sleeve gastrectomy procedure may be considered in patients with a BMI 30 to 35 kg/m² in the presence of very severe medical conditions.
*Severe reflux disease is diagnosed by endoscopy as well as the complaints of the patient.
