Compare weight loss surgeries and evaluate carefully to enjoy good health (Part 2)

In sleeve gastrectomy, a portion of the original bag-shaped stomach is removed to transform it into a thin sleeve-shaped or tube-shaped stomach, thereby achieving the purpose of limiting food intake. Basically, sleeve gastrectomy is a moderate surgery because its effect is exactly between gastric bypass and gastric banding, and so is its safety. Compared with gastric bypass surgery, there is no intestinal reorganization, so there will be no long-term complications after gastric bypass surgery. Such as anemia or osteoporosis due to vitamin deficiency.

Weight loss surgeries include sleeve gastrectomy, sleeve gastrectomy and gastric bypass surgery. People should communicate with their doctors in detail before choosing one.

Compared with gastric banding surgery, there is no foreign body left in the body, and the sequelae caused by foreign bodies can be avoided. However, sleeve gastrectomy still has its disadvantages, because the surgery removes part of the stomach tissue. Therefore, if you regret it due to discomfort caused by changes in diet quality, there is no way to restore the original structure. Therefore, you must communicate with the doctor in detail and think carefully before undergoing the surgery.

After sleeve gastrectomy, an average of 50% of excess weight can be lost in the first year, and 60% in the second year. However, some people will gain weight again, but will not return to their original weight. The mortality rate of this operation is about one in a thousand, and the complication rate is three percent, including bleeding, leakage at the incision site and wound infection.

Gastric bypass surgery involves two parts: one is the reduction of the stomach, and the other is the reconstruction of the digestive tract. The surgery divides the stomach into two parts, large and small. The small part is a cavity of about 30 ml at the junction of the gastroesophageal junction. After the stomach is divided, the digestive tract is reconstructed and the small intestine is bypassed by 150 cm, which has the dual effects of limiting stomach capacity and absorption.

After gastric bypass surgery, an average of 65% of excess weight can be lost in the first year, and 75% in the second year, after which some weight may be regained. A large-scale study found that the mortality rate of surgery was 0.3%, and the complication rate was 5%; these acute postoperative complications are usually caused by intestinal anastomosis leakage. Currently, Chi Mei Medical Center has introduced the Da Vinci robotic surgery method, which can further reduce the incidence of such complications.

Because after gastric bypass, food does not pass through the duodenum and the front jejunum, in addition to reduced calorie absorption, the absorption of some essential nutrients such as vitamins will also be reduced. Therefore, vitamins must be supplemented every day, as well as iron and calcium. Iron deficiency can cause anemia, calcium deficiency can cause osteoporosis, and other reports indicate that vitamin A deficiency can affect vision, while vitamin B deficiency can cause brain disease. In addition, some people may develop marginal ulcers after surgery, causing upper abdominal pain and possibly causing repeated bleeding.

Although the final effects of the above three surgeries may be different, as long as they can achieve weight loss and gain health, they are effective treatment methods. First of all, it is emphasized that no one is necessarily the best, and a comprehensive assessment must be made based on the patient's clinical condition, eating habits and surgical risks. Secondly, cooperation with the physician after surgery is also related to weight loss results. In addition to following nutrition and health education, people who undergo gastric banding surgery need to return for frequent checkups in the early stages to adjust the tightness of the band to a level where they do not feel hungry, do not vomit, and continue to lose weight. As for gastric bypass and sleeve gastrectomy, regular follow-up visits are also required to track whether the body is experiencing nutrient deficiencies or other problems.

In short, surgery is only an external method to force weight loss, but the outcome is still largely controlled by the patient himself.
