What Are the Possible Side Effects of Gastric Balloon?

Gastric balloon procedure is generally a weight loss procedure applied by placing a silicone or polyurethane balloon filled with sterile solution into your stomach. With this process, your stomach volume is reduced and food intake is limited, and at the same time, a feeling of fullness is provided more quickly.

Gastric balloons stay in the stomach for 4 to 12 months, depending on the type. During this period, as in other weight loss procedures, the person is expected to make healthy changes in his lifestyle and diet in order to lose weight and maintain the ideal weight.

The gastric balloon is the safest weight loss procedure with the lowest risk of complications. Unlike surgical procedures, there is no incision and it is reversible. Therefore, there are no scars or scars, and more importantly, no internal changes in your stomach or digestive system. However, as with any medical procedure, this procedure has some complications. In this article, we will discuss possible side effects after gastric balloon procedure.

Side Effects in the First Period After the Procedure:

Nausea and Vomiting

You may experience some stomach discomfort after inserting your balloon. Nausea and vomiting occur in 90% of patients in the first three to seven days after the gastric balloon is inserted. This is because your stomach is not used to it. Nausea or vomiting occurs with the urge to throw out the balloon involuntarily because it cannot digest the balloon like other foods.

You will be discharged with medications to help relieve nausea and vomiting after the application. These drugs will help you get over this condition. Please contact your doctor if your stomach discomfort continues or if you have trouble keeping fluids after the first seven days.

Stomach Cramps

Stomach cramps may occur as your stomach gets used to the balloon, such as nausea. This condition can still be treated with regular medications. Short-term stomach cramps will go away once your stomach gets used to the balloon.


In the first 3 days, you will not be able to eat as before due to complications such as nausea, vomiting and cramps. It is quite normal to feel sluggish in the first week of only fluid intake. Your weight loss journey has begun.

Early Removal

Even if the solution is small, patients think that they cannot tolerate the first-term side effects of the balloon and want it to be removed. Our team will continue to assist you to prevent premature removal, which is considered a last resort for patients battling these complications, which will last 3-7 days.

Complications that can be seen in the following periods after the procedure

Feeling Bloated

The balloon in your stomach can make you feel like your stomach is bloated. This situation, especially after the meal, is due to the balloon itself and the purpose of giving a feeling of satiety and is normal. However, if it is bothersome, it can be treated.

Heartburn and Reflux

After gastric balloon application, heartburn and reflux can be seen in the later period. Certain foods, such as coffee, alcohol, spicy and fatty foods, can further trigger the condition. In such a case, consuming low-fat milk and dairy products can help with reflux.

Decreased Stool Volumes or Bowel Movements

This is normal as less food is consumed after the application.

Bad-Smelling Burping

Sometimes foul-smelling burping can be a problem, as food becomes trapped in and around the mucus lining the balloon. Moving after meals and drinking water after a meal can correct this situation.

Symptoms Requiring Urgent Intervention:

Blue/Green Colored Urine Or Stool.

Gastric balloons placed by endoscopy from gastric balloons are filled with a blue colored saline liquid so that leaks can be detected immediately, albeit with a very low probability. In case of leakage, this liquid mixes with the digestive system and is observed in the urine and feces. In such a case, consult your doctor. Because the leaked balloon causes it to pass through the intestines like normal food and can cause a blockage in the intestines. However, if the swallowable gastric balloon is deflated, this is not the case since it is already expelled from the intestines.

Although it is very rare, it is also worth mentioning the low-probability complications that are usually related to the pre-balloon history, such as ulcer, acute pancreatitis, perforation of the stomach wall after gastric balloon. In gastric balloons placed by endoscopy, the doctor checks whether such a situation exists or not, and can delay the procedure for treatment if necessary.

You should consult your doctor for long-term complaints.
