Weight Loss Surgery

If you have tried conventional weight loss methods and have been unable to maintain a healthy body weight, then bariatric surgery might be the next step on your weight loss journey. Bariatric weight loss surgeries are clinically proven to be safe and highly effective at helping patients lose significant weight and keep it off for life.

As with any surgery, there are risks involved. Bariatric weight-loss surgeries include rerouting, cutting, and stapling of your stomach and digestive tract. Though safe and effective, they are permanent, irreversible procedures. Because of this, they require lifelong adherence to healthy habits, dietary supplements, and routine follow-up appointments.

How To Qualify for Weight Loss Surgery

You may be eligible for weight loss surgery if you meet the following criteria:

  • You have a BMI over 40

  • You have a BMI over 35 and are suffering severe comorbidities as a result of their obesity

  • You are more than 100 lbs over their ideal body weight

  • You cannot achieve healthy body weight, even after medically supervised dieting and exercise

Health Benefits of Weight Loss Surgery

As previously mentioned, bariatric weight loss surgery is highly effective in inducing rapid weight loss for people who have not maintained healthy body weight through conventional means. If you qualify for bariatric weight loss surgery, you can expect to see a 30% to 40% reduction in your excess body weight after six months, with more weight loss following until metabolic homeostasis is reached.

Bariatric surgeries are fully covered by medical insurance. Usually, the patient and their medical team must demonstrate to health insurance providers that the procedure is medically necessary. In most cases, bariatric surgeries are easily proven to be medically necessary. 

Weight Loss Surgery Types

Gastric Bypass

The gastric bypass is the oldest bariatric weight loss surgery option available in the US. Because of this, it is one of the safest and most clinically proven options. This surgery combines restrictive and malabsorptive techniques to help patients lose large quantities of weight. During the procedure, the stomach is stapled to reduce its capacity. Then the stomach is rerouted to bypass the portion of the small intestine responsible for absorbing calories. 


  • Uses restrictive and malabsorptive techniques to induce rapid weight loss
  • Patients feel full faster
  • This leads to the resolution of comorbidities associated with obesity
  • The procedure is performed laparoscopically, so patients receive small incisions 

Gastric Sleeve

The gastric sleeve procedure doesn’t involve rerouting and cutting the intestinal tract, so the original functionality of the intestines is kept intact. Instead, surgeons remove most of a patient’s stomach, leaving only a narrow tube, or sleeve, of the stomach left. This has the effect of reducing how much a patient can eat at one time.


  • Reduces stomach capacity while still allowing for the regular consumption of food, just in smaller amounts
  • Removes the section of the stomach that produces the hunger-producing hormone ghrelin
  • It does not lead to complications surrounding intestinal bypass because this procedure only focuses on the stomach
  • Considered very effective for patients with a high BMI

Gastric Band

If you prefer to try reversible, adjustable, and temporary weight loss surgery options, then you might be interested in the gastric band procedure. During this procedure, a restrictive device is placed around the upper part of your stomach, which vastly reduces its capacity and slows food movement through it. The band is left in place for six to twelve months usually and can be adjusted as needed.

Lap Band Surgery

The lap band surgery was the first of its kind to be approved by the FDA. A surgeon wraps an adjustable device around the stomach to create the narrow passage.

Realize Band Surgery

This procedure uses the second-ever FDA-approved device — a silicone band — to create the narrow passage.


  • Least invasive surgery – no cutting, rerouting or stapling
  • Gastric bands can be regularly adjusted to induce weight loss if a patient starts to gain weight again
  • The adjustable band means customizable weight loss
  • Faster recovery time and less pain 

Single Incision Surgery

Should you qualify for SILS, or single incision laparoscopic surgeries, trademarked by Covidian, then you can receive any of the above surgeries through a single incision. Recipients of SILS have a quicker, less painful recovery time.

Weight Loss Surgery FAQs

Will Health Insurance Cover My Weight Loss Surgery?

Bariatric weight loss surgery is performed on weight loss patients who cannot lose weight by conventional means, so usually, health insurance will cover. Patients and their medical team will have to demonstrate that the surgery is medically necessary, but often this is very easy to prove.

How Much Weight Can I Expect to Lose?

Less invasive procedures, such as gastric band surgeries, do not alter digestion. They make eating large amounts of food very uncomfortable. With this weight loss procedure, patients can expect to lose 1 – 2 lbs per week. 

More invasive weight loss procedures will have a faster, more dramatic effect. Patients who receive a gastric bypass or sleeve gastrectomy can expect to lose between 30% and 40% of their body weight after six months.

What Is the Recovery Time After Bariatric Surgery?

One of the benefits of our single incision laparoscopic surgery method is that the recovery time is faster than if you received multiple incisions.

For the more involved procedures, patients stay in the hospital for two to three days and then can spend the rest of their recovery at home. Generally, after three to five weeks, the weight loss patient can resume normal activities. 

Can Bariatric Surgery Help Treat Type 2 Diabetes?

Yes, if your type two diabetes is a comorbidity resulting from obesity, then bariatric weight loss surgery can help you better manage symptoms.
