I just had a Sleeve Gastrectomy. How much weight should I expect to lose in first four weeks after Surgery?

Hello, I hope you are well. There are many factors that dictate the amount of weight loss, including your eating habits and exercise compliance. Based on the metrics you provided and assuming that you adhere to the recommendations provided to you by your bariatric team, you should be able to lose 60-80 pounds in 4 weeks..

The average weight loss with the sleeve is 15 to 30 pounds the first month.  After the first month, you begin to lose 8 to 10 monthly.  These are just averages, I find that patients that engage in exercise specially weight training tend to lose more inches that weight.  When you exercise, you from more muscle which weights more than fat.  

This varies from patient to patient and there are a lot of factor that go into play including age, activity levels, diet habits, etc. I would suggest you stick to your doctor's guidelines and even seek for some nutritional support to get the most out of your tool. warm regards, Dr. Alvarez
