Common side effects

Side effects in the first weeks

Your stomach needs time to adjust to the balloon. Most side effects are worst in the first days and settle with medication.

Nausea and vomiting

The most common side effects. You’ll get medication to manage them.

Stomach pain and cramping

Reported by about 6 in 10 patients in the FDA trials.

Indigestion and reflux

Heartburn and indigestion are common. You’ll take acid-reducing medication while the balloon is in.

Bloating and other symptoms

Belching, gas, constipation or diarrhea, and a feeling of heaviness.

Early removal

When a balloon is removed early

If side effects don’t settle, or a problem is found, the balloon can be removed early by endoscopy.

  1. 1Why it happens. Most early removals in the FDA trials were because of side effects such as nausea and vomiting. Some patients asked for removal.
  2. 2Spatz can be adjusted. In the Spatz3 trial, 28 patients who wanted their balloon out had the volume reduced instead, and 21 of them completed treatment. Adjustments are quoted separately at Renew.
  3. 3Where it’s done. Removal at Renew is $2,599 in Tijuana or Cancún, including 1 hotel night and transportation. Some patients have their balloon removed by a doctor at home.

Serious complications

Rare but serious complications

The FDA has warned doctors about reports of serious problems with liquid-filled balloons, including deaths, and asks them to tell patients which symptoms need urgent care (FDA).

Ulcers and erosions

The balloon can irritate the stomach lining. Acid-reducing medication lowers the risk.

Esophagitis

Acid reflux can inflame the esophagus, causing burning chest pain that is worse when lying down.

Deflation and blockage

A deflated balloon can move into the intestine and cause a blockage, which may need surgery.

Overinflation

The balloon can fill with air and get bigger, causing discomfort. It may need to be removed.

Acute pancreatitis

Sudden inflammation of the pancreas, which usually causes sudden, severe stomach pain.

A hole in the stomach

Gastric perforation is rare and needs emergency treatment.

When to get help

Warning signs to watch for

Severe stomach pain

Sudden, severe pain, or pain that spreads to your back.

Vomiting that won’t stop

Or you can’t keep liquids down, which can lead to dehydration.

Swelling or bloating

A swollen belly or bloating that keeps getting worse.

Trouble breathing

Pain with trouble breathing or a swollen belly can be a sign the balloon is overinflating.

What to do. For severe pain, vomiting that won’t stop or trouble breathing, go to the nearest emergency room and tell them you have a gastric balloon. Then let your Renew care team know.

Lowering your risk

How to lower your risk

  1. 1Take your medication. Take your acid-reducing and anti-nausea medication as prescribed.
  2. 2Follow your diet stages. Start with liquids, then move to semi-solid and solid foods as your nutritionist advises.
  3. 3Keep in touch. Tell your care team about symptoms early, before they get worse.
  4. 4Remove it on time. Have your balloon removed on schedule. The FDA approved Orbera for up to 6 months and Spatz3 for up to 8 months in the US.

A balloon isn’t safe for everyone. It’s usually not an option if you’ve had stomach surgery, or if you have active ulcers, inflammatory bowel disease, a bleeding disorder, chronic liver disease or are pregnant. Who a gastric balloon is for.
