Gastric ByPass Surgical Procedure in Obesity Clinic Mexico
Is the cutting and stapling of the stomach bye leaving it at its 15% capacity. This pouch is connected to the small bowel, reducing the degree to which food absorption is affected. Because of this, the patient experiences an early and long lasting satisfaction with smaller food amounts. This will be translated into weight loss. Read more >
Before surgery
To prepare for surgery, the patient is asked to arrive at the hospital a few hours before surgery. While in the preoperative holding room, the patient meets the anesthesiologist who explains the procedure and answers any questions. An intravenous (IV) line is placed, and the patient may be given a sedative to help relax before going to the operating room.
ByPass Obesity Surgery Procedure
A gastric bypass is a surgical procedure that creates a very small stomach; the rest of the stomach is removed. The small intestine is attached to the new stomach, allowing the lower part of the stomach to be bypassed.
Gastric bypass surgery is intended to treat obesity, a condition characterized by an increase in body weight beyond the skeletal and physical requirements of a person, resulting in excessive weight gain. The rationale for gastric bypass surgery is that by making the stomach smaller a person suffering from obesity will eat less and thus gain less weight. The operation restricts food intake and reduces the feeling of hunger while providing a sensation of fullness (satiety) in the new smaller stomach.
Obesity affects nearly one-third of the adult American population (approximately 60 million people). The number of overweight and obese Americans has steadily increased since 1960, and the trend has not slowed down in recent years. Currently, 64.5% of adult Americans (about 127 million) are considered overweight or obese.
All procedures aim to restrict food intake and differ in the surgical approach used to create a smaller stomach. Choice of procedure relies on the patient's overall health status and on the surgeon's judgement and experience.
In the operating room, the patient is first put under general anesthesia by the anesthesiologist. Once the patient is asleep, an endotracheal tube is placed through the mouth of the patient into the trachea (windpipe) to connect the patient to a respirator during surgery. A urinary catheter is also placed in the bladder to drain urine during surgery and for the first two days after surgery. This also allows the surgeon to monitor the patient's hydration. A nasogastric (NG) tube is also placed through the nose to drain secretions and is typically removed the morning after surgery.
A diagnosis of obesity relies on the patient's medical history and on a body weight assessment based on the body mass index (BMI) and on waist circumference measurements. According to the American Obesity Association (AOA), a BMI greater than 25 defines overweight and marks the point where the risk of disease increases from excess weight. A BMI greater than 30 defines obesity and marks the point where the risk of death increases from excess weight. Waist circumference exceeding 40 in (101 cm) in men and 35 in (89 cm) in women increases disease risk. Gastric bypass as a weight loss treatment is considered only for severely obese patients.
