Lap Band Surgery in Los Angeles

Previously, lap band surgery was in high demand. 

In this procedure, the lap band surgeons adjust a removable device on a patient's stomach. This act limits the quantity of food that a person can consume, in turn helping the patient lose excessive body fat. 

However, this procedure is now considered less effective than other types of bariatric surgeries. 

Reasons Why People Turned Away from Lap Band Surgery

  1. Patients experienced insufficient weight loss.
  2. Patients faced both short-term and long-term complications.

In most cases, the patients get their bands removed within a period of seven to ten years.

Why Do People Prefer to Have Their Lap Band Removed Instead of Opting for Other Weight Loss Options?

Following are some prominent reasons why people prefer to get rid of their lap bands:

When Weight Loss Is Insufficient After the patients opt for lap bands, they may shed a satisfactory amount of weight in the initial stage. But most of the patients tend to regain their lost weight after some time. In case the lost weight is less than 25-30%, the doctors themselves ask the patients to get the band removed.

When the Band Gets Displaced from the Original PlaceSometimes an extra space gets created on band's above, and the effectiveness of it gets diminished. The patient might be asked to undergo emergency surgery to get the band back in place or get it completely removed. 

When Heartburn Gets Out of ControlThe band may flare up the acid reflux. If this condition gets intense and the medication doesn't work, the doctors may advise getting the band removed. Also, a constant situation like this can swell up the esophagus,  also leading to band removal.

When Digestive Issues Become Unbearable – The band may let the patients feel nauseous and make them vomit due to the feeling. Not being able to swallow also becomes a major issue.

When the Band Gets Eroded Sometimes the band gets eroded inside the body, causing port infection. It must be removed urgently if the infection fails to respond to the antibiotics.

When the Esophagus is Dilated As you know that the band restricts the entrance of food into the stomach, making the food stay in the esophagus for a longer time. It can either dilate or expand the esophagus, which will ultimately lead to the removal of the band.

When Other Damages Occur to the EsophagusSometimes the esophagus becomes immobile due to the band. This condition is known as esophageal dysmotility, which requires quick removal of fluid from the person's esophagus. Also, the removal of the band becomes important in this case.

Lap Band Revision to Sleeve Gastrectomy Surgery

After the lap band removal, the patient can still look for other types of weight loss surgery options.

Nowadays, sleeve gastrectomy surgery is becoming highly popular among people who are determined to get rid of their excess body fat.

Dr. Feiz and associates have performed this procedure several times and are adept at handling cases like these.

Revising lap band procedure to sleeve gastrectomy surgery usually leads patients to complications. But, as the level of complications is less, they are negligible.

The patients who opt for sleeve gastrectomy surgery experience vital weight loss.

Also, this surgery limits the production of ghrelin (hunger hormone) which lets the patient feel less hungry.

Please note: In normal cases, when the person tries to lose weight, the amount of ghrelin produced increases, making it difficult for him/her to eat less and gain a healthy and smart figure. 

What Does Sleeve Gastrectomy Do?

Sleeve gastrectomy allows the patient to intake small amounts of food and permanently lose excessive weight. The weight loss surgeons in Los Angeles perform this procedure laparoscopically (a less invasive method). More so, this procedure requires miniature cameras.


The surgeons remove around 75-85% of the stomach of the patient, so that  it resembles a sleeve.

This treatment lets the patient shed almost 60% of their weight. Plus, those who work even harder to improve their dietary and behavioral habits achieve even better results.


Unlike gastric band surgery, no device from outside is implanted inside the patient's body. In this process, there occurs no reconfiguration of the patient's digestive system, as was done previously in radical gastric bypass operations. After complete recovery, the patient can eat whatever he/she likes.


However, as this process is irreversible, one must make up his mind completely before undergoing the procedure.


More so, sleeve gastrectomy is responsible for the reduced production of the hunger hormone ghrelin. Lesser production of this hormone lets a person crave a lesser amount of food.

Sleeve gastrectomy surgery differs from gastric band surgery in that it does not require a foreign device to be implanted in the body. Additionally, a sleeve gastrectomy does not reconfigure the patient’s digestive system as is done in the older and more radical gastric bypass operation. While this surgery obviously limits the amount of food a patient will be able to eat, once the recovery period is completed, it does not usually limit the type of food that patients can consume. However, it’s important to remember that sleeve gastrectomy is a major life-altering step that cannot be undone. Fortunately, however, complications are rare and the benefits greatly outweigh concerns in most cases.

One aspect of the sleeve gastrectomy that may have been crucial in achieving positive results is the reduction of what is often referred to as the “hunger hormone,” or ghrelin. This substance plays an adverse role in weight loss attempts because it makes people trying to lose weight feel as if they are physically hungry, even though they know intellectually that they have eaten enough food. Additionally, ghrelin may play a negative role in blood sugar metabolism. Reducing its presence in the body of an obese individual seems to be a major benefit of a sleeve procedure.

Sleeve Gastrectomy and Laparoscopic Gastric Bypass in Los Angeles The Good and the Bad

The information below may give you a better idea of the gastric sleeve vs. gastric bypass pros and cons.

Sleeve Gastrectomy in Los Angeles


  • Instrumental in restricting the production of ghrelin. This makes a person feel less hungry while reducing the possibility of a dietary relapse.
  • Less radical procedure.
  • While a major portion of the stomach is removed, your digestive tract remains intact after the procedure.

    Low possibility of digestive tract trauma post-surgery. In fact, sleeve gastrectomy enables a speedy recovery with few, if any, complications. Furthermore, this treatment significantly cuts down on the variety as well as quantity of food that you can eat.

  • Sleeve Gastrectomy also helps in dealing with Type-2 Diabetes. Many diabetic patients have experienced an improvement in their condition after undergoing this procedure.
  • In the long run, patients going through this treatment can expect to lose a considerable amount of weight.


  • After the surgery, you won’t be able to eat a lot since a major part of your stomach will be removed during the process.
  • Irreversible treatment.

Laparoscopic Gastric Bypass


  • Significant weight loss.
  • Additional hormonal benefits after undergoing Laparoscopic Gastric Bypass in LA.
  • Successful track record. Known for effectively treating type-2 Diabetes and Obesity.
  • While not a regular practice, some forms of the process are reversible.


  • Eating lots of food isn't possible after the treatment.
  • You can only consume a smaller variety of eatables post-surgery in Los Angeles.
  • If you continue to overeat or are constantly munching on the wrong kind of food, you might have to deal with “dumping syndrome.”
  • Reordering the digestive tract makes the process more radical. Major trauma can be caused in the affected areas, letting the patient recover slowly.

Point to Ponder: Please be informed that the above-mentioned treatments are well known within medical circles. But, consulting a specialist doctor is crucial before opting for one of them, as every patient is different and may require personalized care.

Weight Loss Surgery Options in Los Angeles

Gastric sleeve gastrectomy surgery is one of the best available options for weight loss.

People feel hungry due to the hunger hormone named “ghrelin.” And in obese people, the production of this hormone is even more. Whenever someone tries to lose weight, ghrelin formation increases as their body is tuned to maintain its original weight. As a result, they feel much more hungry! 

During the sleeve gastrectomy procedure in LA, bariatric surgery doctors remove the part of the stomach responsible for ghrelin production. As a result, you start to feel less hungry, consume little food, and ultimately lose weight.

However, please keep in mind that you’d still have to eat healthy after the surgery to maintain a fit lifestyle.
