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

At 26 years old, with a height of 5’5.5” and a starting weight of 223.6 pounds, your Body Mass Index (BMI) was about 36.5 at the time of surgery.
In the first month after a sleeve gastrectomy, weight loss varies quite a bit from person to person. Some patients may lose 15 to 25 pounds in the first four weeks, while others may see more gradual progress. The average is usually around 10 to 20 pounds, depending on starting weight, adherence to the post-operative diet, activity level, and individual metabolism. Because your BMI was on the lower end of the surgical eligibility spectrum, your weight loss may appear slower compared with patients who begin at much higher weights—but it is still very meaningful for your long-term health.
It is also important to remember that weight loss after surgery is not perfectly linear. Some people lose rapidly at first, while others notice short stalls even in the early weeks. What matters most is the overall downward trend over the first 12 to 18 months, when the majority of weight loss typically occurs.
Focus on hydration, protein intake, and following your bariatric team’s guidelines closely. If you remain consistent, you can expect steady progress, even if the pace is not identical to others you may see online.

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
