Weight loss surgery is still relatively little known in China, but in Europe and the United States has been carried out quite popular, the United States every year nearly 200,000 people receive weight loss surgery, while China now only a few thousand cases per year. This is related to the lack of scientific popularity of bariatric surgery. So who needs surgical treatment? The first thing to do is to take out a calculator and calculate your body mass index, which is the number of weight (kilograms) divided by the square of your height (meters), for example, 100 kilograms, 1.7 meters tall, which is 34.6. People whose body mass index exceeds 37.5 can consider surgery (in fact, they are still quite fat), and it is very difficult for such people to lose weight effectively by their own efforts. If obesity has brought about some related problems such as high blood pressure, high blood cholesterol, etc., then more than 32.5 can be considered for surgery, and if the index of type 2 diabetes is relaxed to 27.5. You can refer to the “Chinese Guidelines for the Surgical Treatment of Obesity and Type 2 Diabetes (2014)”, which is a bit complicated, right? So for everyone, if you belong to 1, body mass index less than 24, then congratulations, you have a very standard figure. 2, more than 24 less than 28, weight has been overweight, can not be allowed to develop to 3, otherwise the consequences please refer to 3. But it is still possible to adjust through diet and exercise, remember seven points by diet three points by exercise. If you do not know the method can consult professionals, we are professionals. 3, has reached the above surgical criteria, please listen carefully, surgery is currently the only long-term effective weight loss methods, surgery to reduce weight is not very easy, who do not like to be operated. But it is the only one at the moment, and there may be better methods that may emerge some years later, but for now weight loss surgery is trustworthy.
