Gastric balloon: what it is, how it works, and what results to expect

Have you ever considered losing weight in a less invasive way than traditional bariatric surgery? 

The gastric balloon has become a popular alternative in the United States for people struggling with being overweight, but who do not yet qualify for or do not wish to undergo more complex surgical procedures.

What is a gastric balloon?

He gastric balloon (also known as an intragastric balloon) It is a temporary device placed in the stomach through an endoscopic procedure. 

Imagine a soft silicone balloon that, once inserted and inflated inside your stomach, takes up space and helps you feel full faster.

Unlike the bariatric surgeries that permanently alter your digestive system, This procedure is reversible and does not involve cuts or alterations to the anatomy of the stomach.. 

The device It remains in the body for approximately six months., during which you actively work to develop healthier eating habits.

How the intragastric balloon mechanism works

The principle behind this treatment is relatively simple: By occupying about a third of your stomach's volume, the balloon reduces the amount of food you can eat. at a meal. When you eat, you feel satisfied much faster than before.

But its function goes beyond simple physical restriction. Research shows that the gastric balloon It also influences hormones related to hunger and satiety.. A study published in Obesity Surgery In 2017, it was shown that patients with the device presented alterations in the levels of ghrelin, the hormone responsible for the feeling of hunger.

Types of balls available in the United States

The FDA has approved three main types of gastric balloons for use in the U.S.:

1. Orbera

The most common type on the American market. This unique balloon is filled with saline solution and remains in the stomach for six months. 

According to data from Apollo Endosurgery, the manufacturer of the Orbera, patients lose an average of 10% of their total body weight.

2. ReShape Duo

It consists of two connected balloons, which provides additional stability. It also remains in the stomach for six months and is filled with saline solution.

Common symptoms include:

  • Nausea (present in approximately 901% of patients within the first 72 hours)
  • Occasional vomiting
  • Abdominal cramps
  • Acid reflux
  • A feeling of constant fullness

The good news? The vast majority of patients report that symptoms decrease significantly after the first week.

Your stomach needs time to adjust. The typical food progression follows this timeline:

  • Days 1-3Only clear liquids (water, broth, gelatin)
  • Days 4-7: Complete liquids (protein smoothies, strained creamy soups)
  • Weeks 2-3: Soft foods (purees, Greek yogurt, well-cooked scrambled eggs)
  • Week 4 onwardsSoft solid foods, with gradual introduction of firmer textures

Throughout the entire six-month period, You work with specialized nutritionists that provide guidance on appropriate portions, nutritious food choices, and mindful eating techniques.

How much weight can you lose

The numbers vary, but the research offers a realistic perspective. 

A multicenter study published in 2015 in Surgery for Obesity and Related Diseases It followed 1,770 American patients who underwent the Orbera procedure. 

The results showed:

  • Average loss of 10.2% of total body weight in six months
  • Patients lost an average of 33 pounds during the period
  • Approximately 771% of patients achieved a loss of at least 51% of their initial weight.
  • The 48% lost 10% or more of body weight

To put it in perspectiveIf you weigh 220 pounds, you can realistically expect to lose between 22 and 33 pounds during the six months with the balloon.

Some patients lose more, others a little less, depending on adherence to the program.

  • Start with light walks of 10-15 minutes daily in the first week
  • Progress to 30 minutes of moderate activity five times per week
  • Add light resistance exercises after the first month
  • Aim for 150-300 minutes of activity per week until the end of treatment

Minor complications (occur in 10-15% of the cases):

  • Dehydration due to persistent nausea
  • Mild gastric ulcers
  • Increased gastroesophageal reflux

Rare but serious complications (less than 1% of the cases):

  • Deflation of the balloon (you would notice blue urine due to the dye)
  • Intestinal obstruction if the deflated balloon migrates
  • Gastric perforation (extremely rare)

The FDA reported some deaths associated with the gastric balloon in 2017, which led to additional safety alerts. However, When the procedure is performed by experienced teams and with adequate support, the risks remain very low..

Ball removal

After approximately six months, it is time to remove the gastric balloon. 

The removal procedure is similar to the placement procedure:

  1. You receive mild sedation
  2. The doctor inserts the endoscope
  3. The balloon is punctured and the fluid drains out.
  4. The empty balloon is removed through the mouth using endoscopic instruments
  5. The whole process takes about 20-30 minutes

You go home the same day and can return to normal activities within 24 hours.

Maintaining long-term results

Here is the truth you need to hear: The period after balloon removal is just as important as the six months with the device.. 

Follow-up studies show that patients who maintain the habits developed during treatment They manage to preserve 75-80% of weight loss after one year.

Strategies for maintaining results:

  • Continue with regular (though less frequent) nutritional consultations
  • Keep a food diary
  • Weigh yourself weekly to detect small increases before they become large.
  • Stay physically active
  • Participate in support groups

Some patients eventually opt for more definitive bariatric procedures after the balloon, especially if they still need to lose significant additional weight.
