Comparison Of Weightloss Surgeries

Restrictive procedures function by reducing stomach size and postponing digestion. 3 quarts of food can fit in a typical stomach. After weight loss surgery, the stomach may initially only be able to hold an ounce, but this may later increase to 2 or 3 ounces. If your stomach is small, you might eat less. The less you eat, the faster you lose weight. All weight loss surgery techniques have been compiled in this article, along with comparison of weightloss surgeries for each.

Surgery referred to as malabsorptive or restrictive affects how well you can absorb nutrients. By reducing the size of your stomach and removing or bypassing a portion of your digestive tract, they make it harder for your body to absorb food. Due to the risks, surgeons rarely perform completely malabsorptive procedures, also known as intestinal bypasses. Electrical device implantation, the most recent of the three procedures, reduces weight by sabotaging nerve signals that travel from the stomach to the brain.

Comparison Of Weightloss Surgeries Vs. Non Surgical Options

Normal weight loss happens rapidly and significantly. The first six months account for about half of it. It may persist for up to two years following the procedure. Diabetes, high blood pressure, high cholesterol, arthritis, sleep apnea, and heartburn are obesity-related conditions that frequently improve with rapid weight loss. The results of gastric bypass surgery have been good over the long term. According to research, a large majority of people can keep off the majority of their weight loss for up to ten years.

Your body type and general health will determine which weight-loss procedure is best for you. For example, less invasive procedures might not be an option if you’ve had stomach surgery in the past or are extremely obese. Discuss the benefits and drawbacks of each procedure with your doctor. Seek medical care where weight-loss surgery is a specialty, if at all possible. According to studies, professional weight loss surgery has a lower risk of complications. Make sure the surgeon has a lot of experience performing the procedure you need, regardless of where you are.

Gastric Band

Gastric banding is one form of restrictive weight loss surgery. During the procedure, the stomach is divided into two portions: a smaller upper pouch and a larger bottom pouch. Because there is still a small canal connecting the two halves, the upper pouch empties more slowly. Only 1/2 to 1 cup of food can be consumed on average before feeling ill or uncomfortable. Additionally, food needs to be soft or chewable. Compared to gastric bypass and other procedures, this one is easier and safer. Your scar will be smaller, you’ll recover more quickly, and the band might even be surgically removed.

The band can also be changed in a doctor’s office. The doctor injects more saline solution into the band in order to tighten it and further reduce the size of your stomach. The band is released after the doctor drains fluid from it with a needle. Compared to other procedures, gastric banding results in a less drastic weight loss. They also stand a better chance of regaining some of the weight they’ve gradually lost.


Vomiting occurs when you eat too much too quickly and is one of the most common side effects of gastric bands. The band could potentially cause problems. It might shift, come loose, or begin to leak. Some people will require additional treatments. An infection could develop after any procedure. Some consequences, though rare, have the potential to be fatal.

Gastric Sleeve

This particular type of limited weight-loss surgery is unique. About 75% of the stomach is removed during the procedure. The stomach is replaced by a tiny tube or sleeve that connects to the intestines. Other weight loss techniques might be too risky for someone who is very obese or sick. A sleeve gastrectomy is a less invasive procedure that enables people to safely lose weight. A sleeve gastrectomy is permanent, unlike gastric banding. Infection, sleeve leakage, and blood clots are examples of potential risks.

Gastric Bypass

Malabsorptive and restrictive techniques are combined during a procedure known as a gastric bypass. During the procedure, the upper and lower portions of the stomach are divided into two sections and sealed. The upper stomach is then surgically connected to the lower end of the small intestine by the surgeon. By removing a portion of the small intestine and stomach, the surgeon is essentially making a food shortcut.


Given that you won’t be able to digest food as well as you once could, you run the risk of not getting enough nutrients. A lack of calcium or iron can lead to osteoporosis or anemia, respectively. For the rest of your life, you’ll need to monitor what you eat and take vitamins. Approximately 85% of people who receive a gastric bypass experience some dumping. Nausea, bloating, pain, sweating, weakness, and diarrhea are a few of the symptoms. Frequent consumption of high-sugar or high-carbohydrate foods can result in dumping.

On occasion, it has turned around. Gastric bypass is riskier because it is more difficult. There is a risk of infection and blood clots, just like with other surgeries. Hernias are also more frequent after a gastric bypass and may need additional surgery to be treated. Gallstones could be a side effect of your rapid weight loss.
