I am 5'4", 190 lbs. About how much weight will I lose if I get the Gastric Sleeve?

Hello, I hope you are well. Weight loss varies from patient to patient, as many factors come into play, including the type of procedure done. In your case, based on the metrics you provided, your BMI is 32.6 which would probably make you eligible for a gastric balloon or a gastric sleeve. Most patients who undergo a gastric sleeve reach their target weight in around a year.

The operation does not cause you to lose weight - it is what you eat and how you eat. If you wish more control and eat healthy then consider the Lap-Band. But if you eat well, and healthy you will stabilize and not loose too much.  

Your BMI is 33.  Insurance will not cover the procedure.  You will have to pay out of pocket.  To answer your question, the average weight loss the first month is 20 to 30 pounds.  After this initial weight loss, you then begin to lose 10 to 15 pounds per month for the next 6 months to a year.  Weight loss continues until you approach a BMI of 20 to 25.  At that time weight loss will slow down and stop.  Weight loss of course depends on life style.  The gastric sleeve has to be combined with a healthy life style for optimal weight loss.
