With the continuous improvement of living standards, the number of obese patients is also increasing. Data show that China has the largest obese population in the world, with an obesity population of 90 million.

Obesity not only reduces the social acceptance of patients, but also causes a series of physiological and psychological problems. Losing weight has become the top priority for every obese patient. Traditional methods of losing weight include controlling diet, increasing exercise, changing lifestyle and medication. Because of the shortcomings of these methods, such as long treatment time, poor effect and easy rebound after weight loss, obese patients began to pin their hopes on weight loss surgery. Today, let's learn something about weight loss surgery that you don't know.

Many patients simply understand bariatric surgery as gastrectomy, which is not comprehensive. At present, laparoscopic sleeve gastrectomy and laparoscopic gastric bypass are commonly used in clinical surgery to lose weight. Sleeve gastrectomy is a real "gastrectomy", which generally removes about 90% of gastric tissue; Gastric bypass surgery only needs gastrointestinal reconstruction.

Who is suitable for weight loss surgery? Body mass index (BMI) is a standard to measure obesity and its degree. According to the formula: body mass index) = weight (kg)/ height (m)2, you can calculate your own body mass index. If the body mass index is greater than 32 and there are no complications, weight loss surgery can be performed. If there are complications such as diabetes, weight loss surgery can be done if the body mass index is greater than 27.5. Under very special circumstances, the patient's preoperative age must be above 14 years old. Of course, the best way is to go to the hospital for testing, or you can find a professional doctor to explain.

Who is not suitable for weight loss surgery? Patients who are intolerant of surgery, such as immature children; Patients with normal body mass index and no complications are not suitable for weight loss surgery, and weight can be controlled by traditional weight loss methods.

The bariatric surgery has a mature development history of nearly 20 years in China, and it has been proved to be a safe and effective method to treat obesity. It has obvious effect on complications caused by obesity, such as fatty liver, hypertension and diabetes, and some patients can stop taking drugs after operation. Patients' breathing and sleep will also be improved, and of course, more importantly, their fertility will be restored.

All operations involve risks, and bariatric surgery is no exception. In the early stage of weight loss, weight loss is rapid, and malnutrition will occur. During this period, it is necessary to supplement nutrition reasonably under the guidance of a doctor, such as eating eggs, drinking fruit juice and supplementing VC. In addition, weight-loss surgery will also produce economic costs, skin relaxation and other problems. In addition, it is particularly important to note that patients who meet the surgical indications should go to regular hospitals for treatment.
