These estimates are the averages we see across published studies. Your weight loss will be different. Renew Bariatrics makes no guarantees or warranties about results.

Faded procedures are outside Renew’s BMI range for that option. Revision estimates use your weight at the time of the revision. This isn’t a medical assessment, and our surgeons make the final recommendation.

How each procedure works, who it suits, how much weight people lose in studies, the risks, and the pros and cons. Weight loss is the share of total body weight lost, measured from the weight just before that procedure.

Which fits you?

Which procedure may suit you

You want the most common surgery

The gastric sleeve is the most performed weight loss surgery in the US (ASMBS estimate, 2023).

You have reflux

Gastric bypass is often preferred. In SLEEVEPASS, 64% of sleeve patients took reflux medication at 10 years, vs 36% after bypass (SLEEVEPASS).

You want the most weight loss, or have type 2 diabetes

The ASMBS describes SADI-S as highly effective for long-term weight loss and type 2 diabetes remission (ASMBS).

You’d rather avoid surgery

Renew offers ESG for a BMI of 29.5 to 40, and the gastric balloon for a BMI of 25.5 to 40.

You want the smallest scar

The single-incision sleeve is done through one incision at the belly button, with results similar to the standard sleeve (2023 meta-analysis).

You’ve already had weight loss surgery

See bariatric revision surgery for options after a sleeve, bypass or Lap-Band. After a bypass, TORe, an endoscopic revisional surgery, tightens a stretched outlet with no incisions.

You’d prefer medication

Our GLP-1 program offers oral and injectable medication with telehealth visits.

The 2022 ASMBS and IFSO guidelines recommend weight loss surgery for a BMI of 35 or more, and say it should be considered for a BMI of 30 to 34.9 with a metabolic condition such as type 2 diabetes. BMI is only one factor. Our surgeons also look at reflux, past surgeries and your health history.

Frequently asked questions

Which bariatric procedure is best?

There isn’t one best procedure for everyone. The right choice depends on your BMI, reflux, type 2 diabetes, past surgeries and goals. Our surgeons review your health history and recommend an option.

Which procedure leads to the most weight loss?

In studies, SADI-S and gastric bypass lead to more weight loss than the gastric sleeve. Endoscopic options such as ESG and the gastric balloon lead to less weight loss than surgery.

Is the gastric sleeve or gastric bypass better for reflux?

Gastric bypass is often preferred if you have reflux. In the SLEEVEPASS trial, 64% of sleeve patients were taking reflux medication 10 years after surgery, vs 36% after bypass.

What is the least invasive option?

The gastric balloon and ESG are done through the mouth with no incisions. TORe is too. It’s a revisional surgery for people who’ve had a gastric bypass. Our GLP-1 program is a medication option with no procedure.

How much does each procedure cost at Renew?

The gastric sleeve is $4,899, gastric bypass and mini gastric bypass are $6,299, SADI-S is $6,899, TORe is $8,599 and the gastric balloon starts at $3,999. The single-incision sleeve, ESG, re-sleeve, sleeve to bypass and Lap-Band to sleeve are custom quotes. Prices are all-inclusive except airfare.

Do you offer the Lap-Band?

Renew does not place new Lap-Bands. If you already have one, we offer Lap-Band removal and revision.

Can I change to another procedure later?

Often, yes. A gastric sleeve can be re-sleeved or converted to gastric bypass, mini gastric bypass or SADI-S, and a Lap-Band can be converted to a sleeve. See our revision surgery page for options.

Can I use HSA or FSA funds?

Yes. Renew accepts HSA and FSA funds and offers financing.
