Gastric sleeve and gastric bypass surgeries help people with obesity lose weight for the long term. These operations change the digestive system to limit food intake or absorption causing major weight loss. Both methods work well, but understanding their differences, benefits, drawbacks, and long-term impacts is key to choosing the right surgery for you.
What’s good and bad about gastric sleeve surgery
Doctors perform gastric sleeve surgery also called sleeve gastrectomy, by taking out a big chunk of the stomach. This leaves a smaller “sleeve” or tube-shaped part. The surgery limits how much you can eat and cuts down on hunger by removing the area of the stomach that makes ghrelin, the hunger hormone.
Gastric sleeve surgery has a big plus: it works well to help people lose a lot of weight. Research shows patients can expect to shed about 60-70% of their extra body weight in the first year after surgery. On top of that, this method is less invasive than gastric bypass surgery. This means patients spend less time in the hospital and get back on their feet faster.
However gastric sleeve surgery has its downsides. A major worry is the risk of vitamin and mineral shortages over time. A smaller stomach means less area to absorb nutrients, which might require supplements for life. Also, though uncommon, problems like leaks, infections, or blood clots can happen.
Pros and cons of gastric bypass surgery
Gastric bypass surgery also called Roux-en-Y gastric bypass, creates a small pouch at the stomach’s top and redirects the small intestine to link to this pouch. This method limits how much food you can eat and reduces calorie absorption by skipping part of the small intestine.
Gastric bypass surgery has a big upside: it helps people shed a lot of weight and gets rid of weight-related health issues like type 2 diabetes and high blood pressure. Research shows that patients can drop about 60-80% of their extra body weight in the first year after the operation. On top of that, this surgery changes hunger hormones, which makes people feel less hungry and more full.
However gastric bypass surgery comes with its drawbacks. The operation is more invasive than gastric sleeve surgery and involves more complex changes to the body’s anatomy. This can lead to a longer stay in the hospital and might increase the risk of problems like leaks, infections, or blockages in the bowel. On top of that, changing the path of the digestive system may cause long-term shortages of vitamins and minerals making it necessary to take supplements for life.
Differences
Gastric sleeve and gastric bypass surgeries both try to help people lose weight, but they work in different ways. The main difference is how they change the digestive system. In gastric sleeve surgery, doctors take out a big part of the stomach. In gastric bypass surgery, they make a small pouch at the top of the stomach and change the path of the small intestine.
These surgeries also affect hunger hormones . Gastric sleeve surgery removes the part of the stomach that makes ghrelin, the hunger hormone. This makes people feel less hungry. Gastric bypass surgery has a direct effect on hunger hormones too. It makes people feel less hungry and more full.
Also, the long-term effects of the two surgeries are different. Doctors can reverse gastric sleeve surgery because it doesn’t change the digestive system’s path. But gastric bypass surgery makes permanent changes to the digestive system’s structure so doctors can’t undo it.
Similarities
