Gastric Balloon Pill - A Guide For Non-Surgical Weight Loss

The gastric balloon pill is a weight loss option that does not require surgery. Doctors use up to three gas-filled balloons, inserted in pill form through the mouth, to take up space in the stomach and make less room for food. This helps patients eat less because they feel full sooner while eating.

This procedure is best for patients who aim to lose a moderate amount of weight. Ideal candidates are between 30 and 100 pounds overweight.

How the Gastric Balloon Pill Works

  • The pill is a capsule that contains a folded balloon

  • Balloon is inflated when it reaches the stomach

  • Balloon in stomach causes patient to feel full sooner while eating, eat less, and lose weight

Gastric Balloon Pill

The gastric balloon pill is attached to a long, thin tube which is connected to a gas compressor. After the balloon capsule is swallowed, x-rays are taken to confirm the balloon is in the stomach. Your doctor will then inflate the balloon and remove the tube.

The inflated balloons rest at the top of the stomach. The balloons make the stomach “crowded,” which makes patients feel full sooner while eating.

Up to three balloons will be placed gradually in your stomach over a 3 month period:

  • Balloon 1 – first visit
  • Balloon 2 – 1 month after 1st visit
  • Balloon 3 (if necessary) – 3 months after 1st visit

Each new balloon will cause the patient to feel more and more full while eating. As a result, you will eat less with each balloon and continue to lose weight at an increasing rate.


Weight Loss

  • Lose up to one-third of your excess body weight in the first six months

  • Results in twice as much weight loss as a moderate intensity diet and exercise routine

Gastric Balloon Pill

The average weight loss with the Obalon gastric balloon pill is one third of the patient’s excess body weight (1). This means that someone who is 100 pounds overweight can expect to lose about 30 pounds in six months.

Long term weight loss (after the balloon is removed) will depend on diet and lifestyle. To reach optimal weight, patients need to follow the advice of their doctors. Creating meal plans and an exercise routine before the procedure contributes to greater weight loss.

The gastric balloon pill is sometimes used for weight loss before surgeries like gastric sleeve or gastric bypass. These surgeries have better outcomes if patients lose weight beforehand.

Speak with your surgeon if you have additional questions about combining procedures.


Health Benefits

  • Weight loss benefits include

Gastric Balloon Pill

The gastric balloon pill is relatively new and there are few studies on its health benefits. So far, findings have identified improvements for the following:

  • Blood pressure
  • Blood sugar
  • Cholesterol
  • Triglycerides (2)

Other common benefits of weight loss are likely, but not yet proven. Benefits of weight loss include:

  • Improvement or resolution of sleep apnea
  • Improved energy
  • Better sleep
  • Improved quality of life
  • Higher self esteem

Weight loss also improves joint health. For every pound of weight lost, there is a 4 pound reduction in pressure on the knee (3). This improves mobility and reduces pain in the knees.

  • Regular use of the following medications (these medications also cannot be taken after the balloon is placed):
    • Aspirin
    • Motrin
    • Advil
    • Blood thinners

  • Same day release from hospital

  • Return to work the following day

Gastric Balloon Pill

The majority of patients can return to normal daily living the day of the procedure. There are no exercise restrictions, and return to work the following day is standard.

The fast recovery is due in large part to its non-surgical approach. Unlike bariatric surgery, there are no medications or scars that slow the recovery process.


Diet and Life After

  • Providers will work with patients on diet before, during, and after the balloons

  • Monitored diet will last a year

  • Long-term lifestyle and dietary changes are necessary for long-term weight loss

Gastric Balloon Pill

Day 1: Clear Liquids

Patients are only allowed to drink clear liquids for the first 24 hours. This diet allows your stomach to adjust to the balloons without stressing the organ. This includes:

  • Water
  • Broth
  • Zero calorie sports drinks (Gatorade, Powerade)

Other points to keep in mind on the 1st day:

  • Drink warm fluids instead of cold
  • Carbonated drinks are not permitted
  • Limit any caffeine intake and be sure to drink at least 8 cups of water a day

Day 2: Soft Food Diet

Patients must follow a soft food diet on the second day. Foods allowed during this phase include:

  • All liquids
  • Pureed fruits
  • Rice
  • Potatoes
  • Cottage cheese and yogurt
  • Oatmeal
  • Eggs

Foods to avoid:

  • Uncooked vegetables
  • Cereals
  • Heavy meats (steak, pork)
  • Bread
  • Corn
  • Crisp fruits (apples, pineapple)

Day 3 – Begin your new gastric balloon diet

Gastric balloon pill patients can begin a normal diet with solid foods on the third day. The best diet is one that is pre-planned and agreed upon with your nutritionist. You should be less hungry with the balloons in, but managing portions remains an important part of weight loss success.

Buying foods from the grocery store instead of eating out can help you save money and maintain discipline. Avoid fast food and prep your meals for the week, and avoid processed foods when possible.

Some patients report having an intolerance for foods they were previously able to eat. This usually includes spicy foods with an acidic profile such as peppers or hot sauce. Spicy foods are not recommended for patients with the balloon.

See our Bariatric Recipes for Dinner for healthy meal ideas.


Exercise is an important part of any weight loss program. Your doctor should work with you on developing a routine that fits your needs.

Patients who exercise benefit in the following ways:

  • Improved mood
  • Reduced risk of cardiovascular disease
  • Increased weight loss
  • Stronger muscle and bones
  • Increased energy
  • Increased risk of disease like diabetes and cancer

Regular exercise over the long term will not only help with your weight loss, but it will improve your quality of life. Finding the right program that you can stick with is important for long term health, weight maintenance, and happiness. The gastric balloon pill should act as a kickstart for getting your body active.

7 Tips for Success:

  1. Start attending a weight loss surgery support group. Support groups can lead to greater weight loss and give patients a safe space to talk about their progress and setbacks.
  2. Maintain healthy sleep patterns. Lack of sleep makes weight loss more difficult, so do your best to maintain a healthy sleep schedule.
  3. Significant weight loss can lead to changes in your relationships. Speak with your partner about your weight loss goals and how life will change when you achieve them. Preparing for this can help with any unexpected challenges.
  4. Use a free diet journal to track your food intake. Patients who use a diet journal lose more weight and make better decisions.
  5. Cut back on sugary drinks. Beverages, including some healthy juices, are often “calorie dense” and carry a high sugar content. Eliminating these drinks can aid in weight loss. Water is always a good choice.
  6. Exercise in the morning. Not everyone can make this lifestyle adjustment, but it’s helpful for those who can. Morning exercise aids in nighttime sleep and sets your metabolic rate for the day.
  7. Take a multivitamin. This will address any nutritional deficiencies that may stem from dietary changes.

Balloon Removal

  • Endoscopic removal is required after 6 months

  • Patients are mildly sedated

Gastric Balloon Pill

Doctors will remove all three balloons after six months. During the final procedure, the doctor will use an endoscope inserted through the mouth and down the throat to deflate the balloons. After the balloons are deflated, the doctor will remove them from the stomach.

Doctors will sedate the patient for the removal. Although anesthesia is not required, patients are required to have a ride home.


Office Visits After Gastric Balloon Pill Removal

  • 6 months of follow up with your doctor

  • Services are included in the cost of the balloon

Gastric Balloon Pill

Patients are expected to continue working with their doctor for an additional 6 months, which is included in the cost of your gastric balloon. Follow-up services include:

  • Weight loss assessments
  • Lifestyle management
  • Dietary recommendations

For the convenience of patients, some doctors work with a “remote wellness provider.” This technology-based service gives patients access to their medical providers via email or texting. It is a great way for patients with busy schedules to continue receiving care after the balloon is removed.



  • Mild side effects including nausea and bloating are common

  • Side effects usually resolve within 1-2 weeks

  • Serious complications are rare

Gastric Balloon Pill

The stomach will need to adjust to the presence of the balloons. This can result in various side effects that usually resolve within 1-2 weeks. Patients who report side effects may benefit from a brief period of inactivity after the procedure.

The Obalon gastric balloon pill trial study took place from March-May 2016. During this trial, side effects for 196 patients were documented. The majority of patients with side effects (82.3%) were reported as mild and resolved within 14 days.

The side effect profile of the study was the following:

Possible Downsides of Gastric Balloon Pill

Side Effects% of Patients
Abdominal Pain ­(Cramping,­Discomfort,­Hunger Pain72.6%
Indigestion ­Heartburn16.7%
Bloating14.6% (4)

When serious adverse events occur, doctors remove the balloons and begin treating the new condition. These events are rare (>1%) and include the following conditions:

  • Gastroenteritis
  • Peptic ulcer
  • Severe gastric irritation
  • Bowel obstruction

Patients should reach out to their doctor if loss of fullness or increased hunger occurs. This may be a sign of a rare balloon deflation. Nausea, vomiting, or pain after the initial balloon symptoms subside may indicate a deflated balloon.

Of the 981 balloons placed during the trials, there was one incidence of balloon deflation. No health issues occurred as a result of the deflation and the balloon was endoscopically removed (removed through the mouth).
