Fat friends who want to do metabolic surgery to lose weight are concerned about how many pounds can be lost by surgery. First of all, we will tell you that how many pounds can be lost is not a scientific indicator, because each fat friend’s height and weight are not the same as their own conditions. We will use how much can be lost in general, such as eligible fat friends, surgery can lose more than 70% of body weight. This is basically having a healthy body for the fat friend. So how many pounds you can lose depends on how much extra weight there is. If you have 100 pounds of excess weight, you can lose at least 70 pounds, and if you have 200 pounds of excess weight (and there are some), you can lose more than 140 pounds. On the question of how long it will take to have noticeable weight loss, this will also vary from person to person, but I can tell you that you will see noticeable results 2 to 3 months after surgery, and usually after a year or a little bit more, your weight will stabilize, and after that the drop will be lower. So you should not worry about your weight dropping all the time, which would not be very safe. And we can tell you, with the weight loss, the patient by obesity-related diseases will also be alleviated, such as type 2 diabetes patients can control blood sugar better, the phenomenon of irregular menstruation of female patients will also be improved and so on. Overall, the quality of life of obese patients can be significantly improved after weight loss surgery. However, I would also like to emphasize that if you want to undergo surgery for weight loss, you must first undergo a rigorous pre-operative examination and assessment, as the surgery has more stringent conditions and restrictions, and it is determined not to be done if you do not meet the conditions. Nowadays, hospitals or organizations with rich experience in treating patients have a better mechanism of pre-operative examination. If a certain hospital has to go to the operating table without giving an examination, we must be more vigilant.
