Directly visual inspection of their own physical condition, compared with their peers, whether excessive obesity. Not only look at the body shape, but also can observe the number of meals to judge. This method is simple, but the error is larger. 2, the more standardized method is the calculation method. Through a scientific formula to determine whether the child is obese. Medically this method is called standard weight BMI method. Body mass index BMI = weight / (height) 2 that is, weight divided by the square of height. The unit of weight is Kg, and the unit of height is m. If the BMI is between 18-25, it is normal weight; if the BMI is between 25-30, it is overweight, but it is not obesity at this time; if the BMI is between 30-35, it is mild obesity; if the BMI is between 35-40, it is moderate obesity; if the BMI is above 40, it is severe obesity. Obesity do bariatric surgery effect? The full name is laparoscopic gastric reduction surgery, also known as sleeve gastrectomy. The principle of gastric reduction surgery is to use the laparoscope to cut out the large curve of the stomach vertically, so that a small gastric sac of about 150 cc is formed in the stomach, which can hold about 4-5 oz of food. It has the advantage of not requiring the placement of foreign objects in the body and the procedure is remarkably effective for weight loss. Method: 2-6 cm of the sinus above the pylorus is preserved in the direction of the greater curvature of the stomach, the greater part of the stomach is removed along the long axis of the stomach, and the entire fundus is removed so that the remaining stomach is “banana-shaped” with a volume of about 60-80 ml. Evaluation: Sleeve gastrectomy has good therapeutic effect on type 2 diabetes and is a widely used surgery for weight loss and diabetes in Europe. This surgery can reduce overweight weight by more than 70% in the first year after surgery, (for example, if 200 pounds, it can reduce more than 60 pounds), and the remission rate of diabetes is more than 75%. Among the three, adjustable gastric banding for weight loss (LAGB) and diversion (By-pass), the treatment effect and postoperative complications are in the middle, so it is the most popular.
