Weight loss surgery can be lifesaving for many people who have a lot of weight to lose and have to go beyond reducing and modifying diet and exercise. Depending on the type of surgery, people can lose up to 30% to 50% of their extra weight within six months. It is usually a big decision. You can’t eat as much afterwards, and it will take a lifelong commitment from you to diet and exercise to keep the kilos off. Since it is major surgery, there will be some risks too.
You can talk to the Best Surgical Gastroenterologist in Delhi to discuss the options and decide what’s right for you. First, you may want to know what to expect from the surgery.
How Weight Loss Surgery Works
There are weight loss surgeries that can prevent the stomach from stretching to full size. Normally, our stomach can hold about six cups of food. After surgery, it can have a cup or so. You start to feel full faster, so you will be eating less and lose a lot of weight. Some surgeries also bypass part of the intestine, so you will absorb fewer calories and lose weight.
Today, most weight-loss surgeries rely on using “laparoscopic” surgery instead of a big cut. The surgeon usually makes five to six of these small cuts in the belly. They will insert tiny tools and a camera through these holes and then guide them and operate while watching a video screen. If that’s not possible, the surgeon will make one large cut along the middle of the belly.
Types of Weight Loss Surgery
Roux-en-Y Gastric Bypass Surgery
This is one of the most common procedures for gastric bypass and is one of the most common weight-loss surgeries. During the surgery, the surgeon will divide the stomach into two parts, where one part is large, and one part is small. The doctors then staple the small stomach portion to make a small pouch. Next, the pouch is disconnected from the stomach pouch from the small intestine (the duodenum). The stomach is reconnected to the second part of the small intestine (the jejunum), thereby bypassing the intestine. After gastric bypass, you will lose weight as you feel fuller after eating less food. The bypass will also enable you to absorb fewer calories, thereby dropping more weight.
Laparoscopic Adjustable Gastric Banding
The surgeon will use laparoscopic tools to insert an inflatable silicone band around the upper stomach. With this procedure, they will tighten the band so that the stomach becomes a small pouch with a narrow outlet. The result is that you will feel full faster, as you eat less and lose weight. Also, the surgeon can tighten or loosen the band or even reverse the procedure as required.
Gastric “Sleeve” Surgery
In this surgery, your surgeon from the best hospital in Delhi will take out most of your stomach and modify your remaining stomach into a tube or “sleeve” shape. The stomach, though, will be attached to your small intestine. After the surgery, your stomach will be able to hold fewer portions of food. As your stomach is smaller, you will feel full sooner. You will not feel hungry because most of the tissue that makes you crave hunger will be gone. This procedure is permanent and thus, can’t be reversed.
This operation is similar to Roux-en-Y gastric bypass, except that it helps connect the small stomach pouch farther down in the intestine. The surgery is a little challenging to do, and thus, not many weight loss surgery centers do this type of surgery. Also, this surgery may leave you short on nutrients.
Vertical Banded Gastroplasty
With the help of staples and a plastic band, the surgeon will make a small stomach pouch. People usually lose less weight with this type of operation than with any other surgeries. This procedure isn’t as common as it used to be. This procedure has been mostly replaced with Roux-en-Y gastric bypass and gastric sleeve.
What to Expect
For your Bariatric Surgery in Delhi, ask your doctor how much weight you are likely to lose. You could also ask what you need to do to keep up the results. You will be asked to eat tiny meals and get regular exercise. Like any other major surgery, some of the major complications occurring soon after the surgery include minor bleeding, infections, and blockages or leaks in the bowel. Some of these complications require surgery. There could be life-threatening issues in some rare cases, such as blood clots, heart attacks, or serious infections.
However, doctors at Vimhans Nayati hospital ensure that surgery is complication-free. Many people stay in the hospital for two to three days after their surgery and can resume normal activities within two to three weeks.
Are you hearing sounds like ringing, roaring, hissing, or buzzing? This may be due to tinnitus, which is an ear disorder that occurs when no external sound is present.
After the Covid-19 infection, black fungus or Mucormycosis spreads and if left untreated then destroys the face, nose, sinus, eye and brain.
