Gastric sleeve surgery vs. gastric bypass surgery, which one is better?

If you have tried different types of diet programs and various exercises to treat obesity but they didn’t work, surgery is the only solution for your problem. Today’s there are different surgical methods to reduce weight. Two following methods are very powerful and common than others:

Gastric sleeve surgery and gastric bypass surgery

Here we want to consider which method is better.

In gastric sleeve surgery, part of the gastric is removed and leaving a thin part of stomach the size of a banana. This surgery helps to reduce weight by two methods:

• Reduce stomach capacity (about 85%) and consequently reduce food intake.
• Reduce hunger hormones

Gastric bypass surgery including two stages:

• In first stage, stomach is divided two sections, the upper section is smaller that can hold about 1 ounce of food.
• In the second stage, parts of the small intestine connect to the punch, so food bypasses parts of the intestine and then body absorb less calories.

 Which method is better?

Although, gastric bypass and sleeve patient’s loss same weight after two years, but we recommend gastric sleeve surgery. Because:

The time of gastric sleeve procedure is less than bypass surgery.

The time of gastric sleeve surgery is less than two hours. But gastric bypass surgery takes more than two hours.

After gastric sleeve surgery you feel less hungry.

The main advantages of this method compare to bypass surgery and other lose weight surgeries is reducing hunger. In this surgery left part of the gastric is cut, it is part of the stomach that produce and discharge ghrelin hormone. This hormone sends the hungry signal to the brain. When this part of gastric is deleted, you feel less hungry and remain full for the longer time.

Weight loss is slow after gastric sleeve surgery.

Usually, gastric sleeve patients lose weight lesser than gastric bypass patients. It prevents of skin fraction and flake.

More addition, if you don’t like other understand that you did surgery, the speed of losing weight of this method is normal and you can keep your secret.

Damping syndrome won’t happen for patients who have had gastric sleeve surgery.

Dumping syndrome or rapid gastric emptying is a condition that food specially sugar move from gastric into the small intestine too quickly.

Vomiting, nausea, bellyaches, diarrhea, bloating, dizziness and heart palpitations are symptoms of dumping syndrome. These symptoms occur about 10 to 30 minutes after each meal.

Gastric bypass patients, usually experience this condition but sleeve patients rarely affect by dumping syndrome.

The recovery time of gastric sleeve surgery is faster.

After gastric sleeve surgery, you have to stay 2 days in hospital and rest at home for 3 days. The recovery time also last for two weeks and you can even resume your physical activities after this time. But after gastric bypass surgery, you should stay 3 days at hospital and three weeks at home. You should also wait about three months for complete healing.

In gastric sleeve surgery, the intestine remains untouched.

After gastric sleeve surgery, your body digest and absorb same volume of food as before the operation because just your gastric is downsized and intestine and other digest organs are untouched. Since parts of your intestine is blocked in bypass surgery, your gastric pathway is changed and consequently essential nutrients and mineral are not absorbed by your body. In this condition, you should receive monthly injection of vitamins and dietary to prevent of food disorders.

After gastric sleeve surgery, you can do endoscopy and have other lose weight surgery if needed.

After sleeve gastrectomy you can do endoscopy because of open approach, if needed, for considering lower parts of the gastric and intestine. More addition, if you need second lose weight surgery, you can do other surgeries.

Gastric sleeve surgery won’t increase the risk of gastrointestinal cancer. 

Despite of gastric bypass surgery that makes a serious change in the digesting procedure and consequently increase the risk of gastrointestinal cancer, gastric sleeve surgery never causes gastrointestinal cancer by itself. In contrast, it prevents of many other cancers such as ovarian cancer because of losing much weight.

The expense of gastric sleeve surgery is less than bypass surgery.

The cost of gastric sleeve surgery is less than bypass surgery. This surgery not only has many considerable advantages, but also is cost effective.
