IS WEIGHT LOSS SURGERY RIGHT FOR ME
Weight loss surgery is not for everyone. Doctors only recommend it for people who:
Have a body mass index (BMI) of 40 or more.
Gastric band is among the least invasive weight loss treatments. This surgery uses an inflatable band to squeeze the stomach into two sections: a smaller upper pouch and a larger lower section.
The two sections are still connected; it’s just the channel between them is very small, which slows down the emptying of the upper pouch. Gastric banding physically restricts the amount of food you can take in at a meal. Most people can only eat a ½ to 1 cup of food before feeling too full.
The food also needs to be soft or well-chewed. Because the band is connected to an opening just beneath the skin in the abdomen, it can be easily loosened or tightened in the doctor’s office.
It’s simpler to do and safer than gastric bypass and other operations. Recovery is usually faster. You can also have it reversed by surgically removing the band.
People who get gastric banding often have less dramatic weight loss than those who get more invasive surgeries. They may also be more likely to regain some of the weight over the years.
The most common side effect of gastric banding is vomiting, a result of eating too much too quickly. It might slip out of place, or become too loose, or leak. Sometimes, further surgeries are necessary. As with any surgery, infection is always a risk.
Roux-en-Y Gastric Bypass
Gastric bypass is the most common type of weight loss surgery. It combines both restrictive and malabsorptive approaches.
In the operation, the surgeon divides the stomach into two parts, sealing off the upper section from the lower. The surgeon then connects the upper stomach directly to the lower section of the small intestine.
Essentially, the surgeon is creating a shortcut for the food, bypassing a section of the stomach and the small intestine. Skipping these parts of the digestive tract means that fewer calories get absorbed into the body.
Weight loss tends to be swift and dramatic. About 50% of it happens in the first six months. It may continue for up to two years after the operation. Because of the rapid weight loss, health conditions affected by obesity – such as diabetes, high blood pressure, high cholesterol, arthritis, sleep apnea, heartburn, and other conditions — often improve quickly. You’ll probably also feel dramatic improvements in your quality of life.
Gastric bypass also has good long-term results; studies have found that many people keep most of the weight off for 10 years or longer.
By design, surgeries like this impair the body’s ability to absorb food. While that can cause rapid weight loss, it also puts you at risk of serious nutritional deficiencies. The loss of calcium and iron could lead to osteoporosis and anemia. You’ll have to be very careful with your diet — and take supplements — for the rest of your life.Another risk of gastric bypass is dumping syndrome, in which food is “dumped” from the stomach into the intestines too quickly, before it’s been properly digested. About 85% of people who get a gastric bypass have some dumping. Symptoms include nausea, bloating, pain, sweating, weakness, and diarrhea. Dumping is often triggered by sugary or high-carbohydrate foods, and adjusting the diet helps. However, some experts actually see dumping syndrome as beneficial, in that it encourages people to avoid foods that could lead to weight gain.Unlike adjustable gastric banding, gastric bypass is generally considered irreversible. It has been reversed in rare cases. Therefore, getting this surgery means that you’re permanently changing how your body digests food.
Because these weight loss surgeries are more complicated, the risks are higher. The risk of death from these procedures is low — about 1% — but they are more dangerous than gastric banding. Infection and blood clots are risks, as they are with most surgeries. Gastric bypass also increases the risk of hernias, which can develop later and may need further surgery to fix. Also, a side effect of rapid weight loss can be the formation of gallstones.
This is another form of restrictive weight loss surgery where 75% of the stomach is removed.
What remains of the stomach is a narrow tube or sleeve, which connects to the intestines.
A sleeve gastrectomy is a simpler operation that allows them a lower-risk way to lose weight.
Because the intestines aren’t affected, a sleeve gastrectomy doesn’t affect the absorption of food, so nutritional deficiencies are not a problem.
Unlike gastric banding procedures, a sleeve gastrectomy is irreversible.
Typical surgical risks include infection, leaking of the sleeve, and blood clots.
The Intra Gastric Balloon is a non-surgical procedure available for weight loss. A soft, expandable, silicone balloon is placed inside the stomach via a camera that enters through the mouth.
Once inserted into the stomach, the empty balloon is filled with sterile saline, occupying a large part of the stomach, creating a feeling of fullness.
Placement of the intragastric balloon takes approximately 20 mins.
Because the balloon is inserted and removed in a day clinic and does not involve surgery, it is considered to be a non invasive procedure.
The Intra Gastric Balloon is completely reversible, and effective in temporarily reducing hunger, controlling food intake, initiating behavioural change, and achieving target weight loss of 10 to 20 kg.
The Intra Gastric Balloon remains in the stomach for a six-month period (some brands- 1 year), where it is then removed the same way it was placed.
