Can we really lose weight through gastric contraction surgery?

After meeting new friends to introduce themselves, many female friends will ask me: [Heard that there is an operation to shrink stomach and lose weight? Is it reliable? To answer this question, it is necessary to first state that what is obese, because many of the girls who ask this question are not fat at all. Not fat, only slightly fat? The internationally used parameter to describe body shape is [body mass index], Citation abbreviation BMI, The calculation method is BMI = weight (kg)/square (m) of height. BMI greater than 25 is overweight. More than 28 is obese, More than 32 is very obese. In the United States, It is suggested that BMI > 40 should be considered as the standard for weight loss by surgery. Or BMI > 35 combined with obesity-related diseases. Converted to the weight of a 165 cm adult, It takes 110 kg or 95 kg to reach the surgical standard. The constitution of the Asia-Pacific population is less resistant to obesity. I looked up the literature, and doctors in the Asia-Pacific region suggested that the indications for weight loss surgery are: BMI > 37, or BMI > 32 combined with obesity-related diseases, such as diabetes, hyperlipidemia, etc. Also converted into 165 cm adult weight, is about 100 kg, or 87 kg and combined with diseases, to meet the surgical standards. Why do you need stomach contraction to treat obesity? Before we talk about the surgical methods, First, popularize some common sense. The order of food travel in the human body is: Dining table-mouth-pharynx-esophagus-stomach-duodenum-jejunum-ileum-colon-rectum-anus-toilet. In addition to the stomach, The human digestive tract is tubular, Only the stomach is swollen and enlarged. Usually fat people eat more, The size of the appetite depends mainly on the volume of the stomach, Therefore, the focus of weight loss surgery is on the stomach. Four major ways to shrink the stomach 1. Resection of part of the stomach wall: [Can’t go back again] Move out part of the stomach wall, Changing the original pouch-shaped stomach into a similar pipeline-shaped one. This is a real [gastric contraction operation], After the operation, because the stomach volume becomes smaller, it is easy to be full if you eat very little, and your body weight naturally drops. The deficiency of this operation is [irreversible]. Some people suffer from the sudden decrease of intake after the operation, which leads to insufficient use of some necessary nutrients in the body and subsequent complications such as anemia. However, [no return]. 2. Gastric bypass surgery: what should I do in the future? In short, it is [taking a shortcut between small rooms], Put the stomach in two, The upper end is a small compartment that connects directly with the jejunum (small intestine). Allow food from the esophagus not to pass through the lower stomach (the large compartment separated), duodenum and upper jejunum. This kind of operation also achieves the goal of losing weight by greatly reducing appetite, easy satiety and less absorption. The disadvantage is that, Since then, there is no way to perform gastroscopy, duodenoscopy examination or treatment, Because the stomach has been fitted with a partition, [Physical disconnection]. The above two kinds of surgery weight loss effect is obvious, But because they all involve cutting and suturing the digestive tract, Therefore, there is a risk of serious complications such as anastomotic leakage, ulcer, scar stenosis, etc. 3. Adjustable gastric contraction band: The belt of the stomach is simply said, which is just like tying a belt. Tie an adjustable belt to the stomach. According to the postoperative situation, stretch the belt. If you want to eat less, shrink it. If you want to eat more, loosen it. The advantage of this operation is that the digestive tract did not get a knife. If you regret it, you will still be the same as normal people after taking out the belt. The disadvantage is that there is a [foreign body] in the body, which may bring adverse effects to the body. In addition, the weight loss effect is also general. 4. Silicone water polo: All three operations can now be performed laparoscopically, The surgeon only needs to make a small eye in the stomach to complete the operation. That is, minimally invasive surgery. Later, physicians invented the fourth non-invasive weight loss surgery: place a small silicone water polo into the stomach through gastroscope, and then inject water into it to make it gradually expand, occupying most of the space of the stomach, making people always feel full and unable to eat a lot of things. This kind of surgery, the advantage is that there is no anesthesia and no scar on the body; The disadvantage is that the weight loss effect is general, and it is easy to get stomach trouble after a long time. Weight loss surgery for diabetes? These are the four kinds of weight loss surgery currently in common use. In Europe and the United States, where there are more big fat people, Hundreds of thousands of obese people who meet the surgical indications undergo surgery every year. They were originally designed to lose weight. However, many years of follow-up observation have found another [unexpected] [unexpected] benefit-the treatment of diabetes: Some obese people with type 2 diabetes have not lost much weight after surgery, but they have reduced the dosage of hypoglycemic drugs, and even there are cases of [complete cure]. Therefore, some diabetic patients will also undergo weight loss surgery now. However, not all diabetic patients are suitable for such surgery. After doing so, only about 80% of the patients can improve their condition, and some of them will return to their preoperative state several years later. Do you want to lose weight by surgery? Losing weight is nothing more than [moving more] and [eating less]. Surgery can only make an issue of [eating less], not to mention spending money, and there are risks. As long as you are not extremely obese or have diseases caused by obesity, I suggest you use perseverance to do [eating less], the effect is as good as surgery.
