Gastric sleeve surgery, also called sleeve gastrectomy, is a bariatric surgery procedure. It removes a large portion of your stomach, leaving behind a narrow “sleeve.” Reducing your stomach helps restrict calories and reduce hunger signals. This surgery is offered to help people with clinically severe obesity achieve effective weight loss.
Gastric bypass surgery is a type of bariatric, or weight loss, surgery. During gastric bypass surgery, your physician makes changes to your stomach and small intestine to change the way they absorb and digest food.
Gastric bypass aids weight loss by:
-Restricting the amount of food that your stomach holds
-Limiting the amount of calories and nutrients your body absorbs
-Changing your gut hormones, which help you feel fuller longer, contribute to appetite suppression and the reversal of obesity-caused metabolic syndrome.
The gastric sleeve, also called sleeve gastrectomy, is a bariatric surgery operation to induce weight loss. It works by reducing the size of your stomach. The word “gastrectomy” means removal of part or all of your stomach. The gastric sleeve operation removes about 80% of your stomach, leaving behind a tubular “sleeve,” about the size and shape of a banana.
What Can I Expect After Gastric Bypass Surgery?
For the first month, you will only be able to handle small amounts of soft food and liquids. But gradually, you will be able to add solid foods back into your diet. You will notice feeling full very quickly – after eating about two tablespoons of food. Your physician may also recommend that you take nutritional supplements.
Within the first two years, you can expect to lose one-half to two-thirds of your excess body weight. Weight loss will continue, in most cases, for a year and a half before stabilizing.
What does a gastric sleeve do?
Reducing the size of your stomach is a simple way to restrict the amount of food you can eat in one sitting, making you feel fuller faster. But it also serves another purpose: it reduces the amount of hunger hormones that your stomach can produce. This helps to decrease your appetite and cravings and may help to prevent the impulses that cause people to regain the weight they’ve lost.
How common is gastric sleeve surgery?
The gastric sleeve is the most commonly performed weight loss surgery in the U.S. and worldwide. More than half of bariatric surgeries performed in the U.S. each year are sleeve gastrectomies. The total number of gastric sleeve operations performed each year is about 150,000 in the U.S. and 380,000 worldwide. But, only 1% of people who could benefit and would qualify for the surgery actually get it.
What medical conditions does gastric sleeve surgery help treat?
Gastric sleeve surgery is a surgical treatment for obesity and medical conditions related to obesity. It’s only offered to qualified people who have serious medical conditions related to their obesity or are at high risk for developing them. Gastric sleeve surgery can improve and sometimes eliminate diseases, including:
-Insulin resistance and Type 2 diabetes.
-Hypertension and hypertensive heart disease.
-Hyperlipidemia (high cholesterol) and arterial disease.
-Nonalcoholic fatty liver disease and steatohepatitis.
-Obesity hypoventilation syndrome and obstructive sleep apnea.
-Joint pain and osteoarthritis.
Is the gastric sleeve safe?
The risks of gastric sleeve surgery are far less than the risks of having obesity and its related diseases. It also has lower complication rates than other common operations, including gallbladder removal and hip replacement. Most gastric sleeve procedures are performed by minimally invasive surgical techniques, which means less pain from incisions and faster recovery.
