Realistically, after getting the gastric sleeve, how many pounds will be dropped by 4 weeks post surgery?

Hello!    The answer varies depending on your starting BMI but for patients with a BMI 40+ like yourself  a realistic goal may be to lose 1 lb a day during the first month.   This is  if you are following the post surgery healing diet your surgeon will provide.   This will not be the rate at which you will continue to lose though. The first month post VSG is when patients experience the most rapid weight loss. 
Patients with a lower BMI lose weight at a slower rate but reach their goal weight fairly quickly and can focus on the maintenance phase. 

Hello,
Thank you for your question. In my experience, patients tend to lose 20-30 pounds in the first month and average 10 a month thereafter. Factors that influence the rate and total weight loss include gender, age, starting BMI, and extent of lifestyle changes. It's not uncommon for weight loss to have periods of plateau; it's important not to feel discouraged during these times and to look to your care team and support network for guidance and encouragement.
Best wishes,
Dr. Moein

Hello, Ideally a patient who had a gastric sleeve patients is from 20 to 30 pounds the first month. After that period you can expect 8 to 12 pounds per month
