A gastric sleeve and gastric bypass are weight-loss surgeries that help patients lose weight by changing the size of their stomachs.

While both procedures are effective, there are some differences between them that you should be aware of before deciding which surgery is right for you. This article will explain how each procedure works and what you can expect after undergoing either.

Gastric sleeve gastrectomy

The gastric sleeve is a weight-loss surgery that permanently removes about 75% of the stomach. Studies have shown that people who have this surgery lose about 65% more weight than people who have had gastric bypass surgery. People who get the surgery typically lose between 50 and 100 pounds in the first year after surgery.

  • The gastric sleeve is a restrictive procedure.
  • This means it’s focused on reducing your stomach size rather than rerouting food to another part of your digestive tract, which isn’t necessarily bad for those with less severe obesity.
  • Once the procedure has taken place, you’ll have one-third or less of your original stomach left and an opening from where food enters at the top third down to where it leaves your body in the bottom third.
  • While this may appear like it would prevent you from eating much, its small size allows you to feel full after only eating small amounts at any given time—and ultimately helps you achieve weight loss success!

Gastric bypass

Patients may yield 30 to 50 % of their excess weight in the first six months and 77 % as early as 12 months after surgery. A different study found that patients could keep off 50 to 60% of their excess weight 10 to 14 years after surgery.

  • Gastric bypass is a surgical process that creates a small stomach pouch and connects it to the middle part of the small intestine.
  • Gastric bypass is a restrictive procedure that reduces the amount of food eaten at once.
  • The pouch size limits how much food you can eat at one time by reducing your stomach capacity, which helps reduce hunger pangs between meals.

What are the Risks?

In surgery, risks include infection, bleeding, and blood clots. Chances are more significant in the elderly, those with other medical conditions, and smokers.

However, bariatric surgery may lead to severe complications for a small number of people. These include:

  • Leakage or blockage at an anastomosis (connection) between your stomach and intestines
  • Rupture of one or more stitches inside your abdomen
  • Intestinal obstruction (blockage) caused by scar tissue or narrowing at the site where the intestine was joined together after surgery
  • Adhesions between internal organs cause bowel obstruction

Who is a Good Candidate?

You must be at least 18 years old to qualify for a gastric bypass, but the age of patients is between 40 and 60 years old. In addition, you should have an ideal body mass index (BMI) between 30 and 35—the BMI is an analysis based on your height and weight. You also need to be in good health, with no severe medical conditions that would prevent you from following this surgery.

If you have never been obese before or if you have never had any weight issues, then a gastric sleeve may not be suitable for you. This surgery is designed specifically for those who are severely obese—those who are 100 pounds overweight or more, usually with a BMI over 40 or higher than 35 if they’re not quite as heavy yet still very overweight by most standards—and it will likely help them lose all their excess fat faster than other methods would do so on their own…

What’s the difference between these two surgeries?

What’s the difference between these two surgeries
  • Gastric bypass is a revision surgery, which means it’s done to fix an existing problem with the digestive system.
  • Gastric sleeve gastrectomy is primary surgery. It’s the first time your surgeon will be making any cuts in your stomach—or rather, it’s the first time you have anything done to it.

Is there a difference in the recovery?

There is no difference in the recovery time for these two surgeries.

Gastric bypass surgery is more invasive and has a longer recovery time. Still, proper care and monitoring should not impact your ability to return to work soon after getting home from the hospital.

The gastric sleeve procedure has a shorter recovery period because it’s less invasive and doesn’t require significant changes to your digestive tract.

Dietary changes

The Dietary plan for gastric sleeve and gastric bypass surgery is an essential part of the surgery. The program is designed to allow your stomach to heal and to help you lose weight. It is necessary to follow the plan closely to ensure that you heal properly and do not have any complications.

After gastric sleeve surgery

  • Juices and soft foods are best for the first few days.
  • After the stomach has healed, start with semi-solid foods.
  • Continue to eat healthy – small meals five times a day.

Avoid the following foods for some time:

  • Very hot or freezing foods or liquids
  • Fatty, fried, or greasy foods
  • Alcohol
  • Caffeine
  • Salt
  • Hot spices and seasonings.

After Gastric Bypass Surgery

  • Protein and fiber-rich foods are strongly encouraged for this surgery
  • This includes lean meats, fish, poultry, beans/legumes/pulses, eggs, and dairy products (low-fat is best).
  • Whole grains are also encouraged for this surgery type–they’re filling!

Avoid the following foods for some time:

  • Solid fats (butter, margarine, oils)
  • Large amounts of meat, fish, poultry, and shellfish
  • Fatty or fried foods and sauces
  • Foods with sugar or sweet syrups, such as soft drinks

  • An experienced surgeon is necessary.
  • The potential for food to remain in the pouch for a long time.
  • A change in eating habits

  • Lose weight without feeling hungry.
  • Reduce the risk of disease.
  • Reduce the risk of type 2 diabetes.
  • The surgery is minimally invasive

How Doctor Decides Which Bariatric Surgery Is Right for You

Your doctor will first evaluate your weight and height to determine which type of bariatric surgery is right for you. Doctors look at your body mass index (BMI), a measure of body fat based on height and weight, and other factors such as age, gender, and current medical conditions. They may also consider the status of any other medical issues you have.

Doctors must consider how old they are because younger patients tend to have more significant surgery risks than older patients. In addition to age, doctors consider lifestyle choices when deciding whether or not gastric bypass or sleeve gastrectomy is best suited for an individual patient.

Who qualifies for gastric bypass or sleeve?

If you have a BMI of 40 or greater and have been unable to lose weight through diet and exercise, you may be a good candidate for gastric bypass surgery. The procedure is often recommended for those who are severely obese and exhibit high blood pressure, diabetes, and other chronic medical conditions.

If you have a BMI of less than 40 but still want to lose weight, gastric sleeve surgery may be the right choice. Since it is less invasive than gastric bypasses, many insurance providers will also cover this procedure.


Do you lose weight faster with a gastric sleeve or bypass?

Both gastric bypass and gastric sleeve surgery can help you lose weight. The two procedures have similar weight loss results over the first few years. Both methods are usually followed by lifestyle changes, like exercise, changing diet, etc.

Is gastric bypass safer than sleeve?

Gastric bypass surgery is much more invasive, and you’ll likely have more complications. The sleeve is a minimally invasive procedure done laparoscopically.

Which is the most successful weight loss surgery?

Gastric bypass and sleeve gastrectomy are both effective weight-loss surgeries. Gastric bypass surgery is the most successful, long-term weight loss surgery.

Does insurance cover bariatric surgery?

Yes, insurance covers bariatrics.” Insurance companies protect bariatrics for two reasons. First, to cover the costs of health care. Second, it is a way of preventing future expenses by improving the insured’s health.

How painful is gastric bypass surgery?

Not at all. The surgeon will give you a shot to numb the area. You may feel some discomfort and pressure while they are stitching you up. But other than that, you should feel no pain.

Is gastric bypass forever?

Yes, gastric bypass is permanent. There is no going back once you’ve had it done.

How long does a gastric sleeve last?

Gastric sleeve surgery is designed to be a permanent weight loss solution. As with any surgery, there will be some initial pain and healing time, but once that is over, you should be able to maintain your weight loss and keep it off for the long term.
