Obesity and Gastric bypass

Obesity and Gastric bypass

Gastric bypass is the surgical reduction of the stomachÂ’s size. You begin to eat less and start to lose weight quickly.

“Laparoscopic gastric bypass” is a technique by which the stomach is left with a capacity of 15 to 30 ml and is connected directly to the small intestine. As a result, food skips a large segment of the small intestine, reducing absorption of calories and nutrients. Furthermore, due to the small size of the stomach, the amount of food that one is able to eat is reduced and you feel satiated with less while beginning to lose weight.

This is currently one of the most commonly practiced surgeries for severe obesity. It is considered to be one the surgeries with the best results, and one that least affects the quality of life for the person who undergoes the surgery.

Who is the ideal candidate, and who is not?
Doctor Ruiz Orellana, specialist in General Surgery and the Digestive System at HC Marbella advises that this type of surgery is not for everyone. Saying that: “Ideal
candidates for gastric bypass are those that fit the following conditions”:

  • Patients should be between 18 and 65 years of age, although patients outside of this range may be considered.
  • Have a body mass index (BMI) of 40 or greater or have a BMI of 35-40 with serious related health problems, such as diabetes, cardiac issues, high blood
    pressure, high cholesterol, or sleep apnoea.
  • Men who have more than 45 kilos (100 pounds) of excess weight and well above their ideal weight; women who have more than 36 kilos (80 pounds) of excess
    weight above their ideal weight.
  • Those who are obese and have already tried other weight loss methods.
  • Be willing to live a healthy lifestyle that includes a regular exercise regimen for the rest of their life.
  • Must not have an untreated psychiatric condition according to a psychologist or psychiatrist
  • Understand and complete the instructions and guidelines of the program
  • Understand and accept the risks of the weight loss surgery
  • Have a support network of friends and family that will help achieve the goal of a health weight • Accept complying to long-term followups



Gastric bypass presents numerous advantages:

Rapid weight loss. On average a loss of 60-70% of the excess weight. It is considered to be a success if at least half of the excess weight is lost, although in some cases, patients regain a part of the lost weight. No surgery is successful for 100% of patients.

  • It stops food calories from being absorbed as they would have been.
  • It improves the treatment of certain pathologies (up to 80%) such as diabetes mellitus, hypertension, hyperlipidaemia, asthma, gastritis and sleep apnoea.
  • Improves backaches, arthritis, and depression in 70% patients.
  • Deficit in the absorption of sugars and fats that help with weight loss – produced by the mixed surgical procedure that is the bypass itself.
  • At HC Marbella gastric bypass is performed by laparoscopy, which is more advantageous than conventional surgery and it reduces the time spent in the hospital to three days.

Gastric bypass offers great advantages that speak for themselves, however one must remember that it is important to know that this surgery is associated to a malabsorptive component, which requires the restoration of some minerals and vitamins, typically iron, vitamin B12, requiring greater nutritional control.

Furthermore, as the surgery is a mechanic medium to control food, the cooperation of the patient is needed to adapt their lifestyle to the new conditions presented by the surgery and commit to a diet program that covers their nutritional and vitamin needs.

Once a balanced weight is achieved (not predictable in advance), the body readjusts to the new intake and self-maintains the weight.
The Nutrition Centre at HC Marbella will create a personalised diet program to cover your nutritional and vitamin needs, but you will have to commit yourself to maintaining healthy eating habits.

One of the main factors for a successful gastric bypass is the firm commitment to a healthy lifestyle.
