What is the average weight loss after gastric sleeve surgery?

The average weight loss after gastric sleeve is 15 to 30 pounds the first month.  After the first month, most lose 8 to 12 per month.  Weight loss usually continues from one to one and a half years post op depending on BMI.  The total average weight loss with the sleeve the first year is 10  to 150 pounds.  

The average weight loss after gastric sleeve surgery can vary from person to person, but typically, patients can expect to lose about 25–35% of their total body weight within the first 6 to 12 months post-op. In the first 8 weeks, many people lose around 10–15% of their starting weight, though this can be influenced by factors such as initial BMI, adherence to dietary guidelines, activity levels, and individual metabolic differences.
In your case, going from 109 kg to 97 kg in 8 weeks is a loss of 12 kg, or roughly 11% of your total body weight, which actually falls within the expected range. It's completely normal to wonder if you're progressing fast enough, especially when comparing yourself to others, but it's important to recognize that every body responds differently to the surgery. Your weight loss so far shows that your body is responding well — and consistently.
Keep in mind that the early weeks are also a time of healing and major adjustment. Some people see rapid loss at first and then slow down; others lose more steadily over time. What matters most is continuing to follow your surgeon’s or dietitian’s guidance, staying active, prioritizing protein, hydration, and long-term habits.

Hello, I hope you are well. Weight loss rate following a gastric sleeve varies from patient to patient. Several factors interfere in how fast you lose weight including metabolic rate, eating habits, diet compliance, your starting weight, etc. Everyone's weight loss journey is different, as long as you are adhering to your bariatric team's recommendation I would advice you to be patient.
