Gastric Bypass vs. Gastric Sleeve

Understanding the Difference: Gastric Bypass vs. Gastric Sleeve

Description

Dr. Fernando Garcia describes the difference in gastric bypass vs. gastric sleeve surgery. Dr. Garcia and the team at Tijuana Bariatrics provide both types of surgery. Dr. Garcia works closely with patients to determine which type of surgery is best, based on their eating habits and lifestyles.

In a patient who is a sweets-eater, or the patient who likes to eat all the day a small amount of meals, I recommend the gastric bypass. Why? Because they don't like to fill the stomach in each meal, but they are going to eat a small amount of food or sweets, or anything like that, and all of that food is going to absorb and is going to store itself in your body in the fat tissue. There is another kind of patient. The patient who eats a little bit in the morning and during all the day doesn't eat anything, and probably when they go home they have the time to eat whenever they want. This kind of patient is better for the sleeve only. Why? Because with the gastric bypass we have to change more things in the bowel and things like that, and it is a longer surgery. Our thing is when the patient is a younger female, she would have to wait 24 months after the surgery to get pregnant. It's a little bit more risky if they have a gastric bypass. Why? Because they are not going to absorb all of the nutrients and vitamins and that can cause some problems in the baby. For me? Gastric bypass is for sweets-eaters if they have a child or they don't want to be pregnant again, because they will have to wait longer and take a lot of vitamins. With the sleeve, in the future they are going to eat like before, with small amounts of food, but they are going to absorb almost completely all the nutrients. But in the gastric bypass, they stay forever with kind of malnutrition or malabsorption so they have to be more conscious of the protein, the vitamins, the iron, calcium and things like that. We have two options or optional factors. We can restrict the food intake or we can cause some malabsorption in the bowel. The sleeve is only a restrictive procedure, so people are going to probably feel full faster when they eat in the beginning. The food is going to absorb after it passes through the stomach. When it stays in the bowel, it is going to absorb completely. That's why if people start eating sweets, like ice cream, chocolate, cappuccino coffee, complete sugar, they are going to absorb completely. It's different than the gastric bypass. In the gastric bypass we have to reduce the size of the stomach. We divide it into parts, and the smallest part is going to connect or join with the bowel. We have to make a cut in the bowel, and to join between the both part of the bowel, and later up to the stomach, to cause a kind of malnutrition, so this patient will have two factors: restrictive and malabsorptive. But in the sleeve they only have the restrictive factor or consequence.
