Obesity is a serious problem for many people. People try different methods to lose weight, including surgery, exercise, and diet. A gastric balloon is a popular non-surgical option to lose weight. It involves putting a balloon in the stomach to reduce the amount of food a person eats. But, is it safe and effective? In this blog, we will look into gastric balloons and determine if they are a safe and effective option to lose weight.

What is a Gastric Balloon?

If you or someone you know is struggling with obesity, you may have heard of a weight loss procedure called a gastric balloon. But what is it exactly?

Definition and Explanation of Gastric Balloon

Doctors use a soft silicone balloon, inserted through your mouth using an endoscope, to help you lose weight without surgery. Once healthcare providers put the balloon in place, they inflate it with a sterile saline solution. This takes up space in your stomach, which helps you feel full faster and eat less food.

Types of Gastric Balloons

There are several types of gastric balloons, but they all work similarly. Here are some of the most common types:

  • Single Intragastric Balloon: Doctors fill this type of balloon with a saline solution and place it in your stomach for up to six months.
  • Dual Intragastric Balloon: This type of balloon is like a single balloon, but there are two balloons instead of one.
  • Swallowable Balloon: This type of balloon is a pill that you swallow. Once it reaches your stomach, it is inflated with a saline solution.

How Does it Work?

The idea behind the gastric balloon is simple: it takes up space in your stomach, which helps you eat less food and lose weight. When the balloon is in place, you will feel full faster, and you will be less likely to overeat. It’s important to note that the balloon is only a temporary solution, and it’s up to you to make lasting lifestyle changes to maintain your weight loss.

Is it Right for You?

Before considering a gastric balloon, it’s important to talk to your doctor. You may be a good candidate if:

  • You have a BMI (body mass index) between 30 and 40.
  • You have tried other weight loss methods without success.
  • You do not have any medical conditions that would make the procedure risky.

Who is a good candidate for a gastric balloon?

A gastric balloon is a non-surgical weight loss solution that can be a good option for some people. Here are some factors that can make someone a good candidate for a gastric balloon:

Health Conditions

Gastric balloons are generally recommended for people who are overweight or obese and have health conditions related to their weight, such as:

  • Diabetes
  • High blood pressure
  • Sleep apnea
  • Joint problems
  • Other weight-related health conditions

BMI Requirements

Body mass index (BMI) is a measurement of body fat based on height and weight. Gastric balloons are typically recommended for people with a BMI of 30 or higher. But, some people with a BMI of 27 or higher may also be eligible if they have weight-related health conditions.

Willingness to Commit to Lifestyle Changes

A gastric balloon is not a quick fix for weight loss. It requires a commitment to lifestyle changes, including a healthy diet and regular exercise. Individuals willing to make lifestyle changes and fully commit to them are good candidates for a gastric balloon.

Psychological Evaluation

Before getting a gastric balloon, it’s important to have a psychological evaluation to determine if you have any underlying mental health conditions that may affect your ability to make lifestyle changes or adhere to the aftercare instructions.

Age Requirements

Gastric balloon procedures are typically not recommended for individuals under 18 years old, as the procedure may be unsafe for children and teenagers whose bodies are still developing.

Absence of Certain Conditions

Some conditions may make someone ineligible for a gastric balloon, including:

  • Previous gastrointestinal surgery
  • Active stomach ulcers or other stomach problems
  • Pregnancy or breastfeeding
  • Certain medical conditions that affect the digestive system

It’s important to talk to your healthcare provider to determine if a gastric balloon is a good weight loss solution for you. They can check your health and determine if you meet the criteria for a gastric balloon.

How effective is a gastric balloon in promoting weight loss?

Gastric balloons can help people lose weight, but the amount of weight loss can vary from person to person. Studies have shown that gastric balloons can help people lose an average of 5–10% of their starting weight.

How does a gastric balloon help with weight loss?

A gastric balloon is a soft, silicone balloon that is placed in your stomach. It takes up space in your stomach, which makes you feel full faster and eat less food. When you eat less, you consume fewer calories, and this can lead to weight loss.

How much weight can you lose with a gastric balloon?

The amount of weight you can lose with a gastric balloon varies depending on several factors, including:

  • How much did you weigh before getting the balloon
  • How long do you keep the balloon in your stomach?
  • How much do you change your diet and exercise habits while the balloon is in place?

On average, people who get a gastric balloon lose 5–10% of their starting weight. For example, if you weigh 200 pounds before getting the balloon, you might lose 10–20 pounds.

Is a gastric balloon a permanent weight loss solution?

After six months, your healthcare provider will remove the gastric balloon, and you will be responsible for maintaining the weight loss achieved during the procedure by continuing to eat a healthy diet and exercising regularly.

How does gastric balloon compare to other weight loss methods?

Gastric balloons are a way to lose weight without surgery. They are not like diet or exercise. They are more effective than those methods. But, they are not as effective as surgery.

What are the Risks and Potential Side Effects of Gastric Balloons?

Gastric balloons are a popular weight loss solution, but like any medical procedure, they come with risks and potential side effects. Here are some of the common risks and side effects associated with gastric balloons:

Short-Term Side Effects

  1. Nausea and vomiting
  • It’s normal to feel nauseous or vomit after getting a gastric balloon. This is because your stomach is adjusting to the new device.
  1. Abdominal pain and discomfort
  • You may experience discomfort or mild pain in your abdomen as the balloon takes up space in your stomach.
  1. Reflux and heartburn
  • Some people may experience reflux or heartburn after getting a gastric balloon. This occurs when stomach acid flows back into the esophagus.

Long-Term Risks

  1. Balloon deflation or rupture
  • Although rare, there is a risk that the balloon could deflate or rupture while in your stomach. This can cause serious complications, such as intestinal obstruction or perforation.
  1. Bowel obstruction
  • In some cases, the balloon can block the digestive tract, leading to bowel obstruction. This requires immediate medical attention.
  1. Nutritional deficiencies
  • Since the gastric balloon takes up space in your stomach, you may not be able to eat as much as before. This can lead to nutritional deficiencies if you’re not getting enough nutrients in your diet.

Complications Associated with Gastric Balloons

  1. Infection
  • Any time a foreign object is inserted into the body, there is a risk of infection.
  1. Bleeding
  • The placement of the balloon can cause bleeding in rare cases.
  1. Allergic reactions
  • Some people may have an allergic reaction to the materials used in the balloon.

It’s important to note that not everyone will experience these risks and side effects. However, it’s important to discuss these potential complications with your healthcare provider before deciding on a gastric balloon.

If you experience any severe or persistent side effects after getting a gastric balloon, seek medical attention immediately.

What is the process of getting a gastric balloon?

Getting a gastric balloon involves several steps, including consultation and evaluation with a healthcare provider, placement procedure, and follow-up care. Let’s take a closer look at each of these steps.

Consultation and evaluation

Before getting a gastric balloon, you’ll need to have a consultation and evaluation with a healthcare provider. This is to determine if you’re a good candidate for the procedure and to discuss any potential risks or complications.

In the consultation, your healthcare provider will ask about your medical history and any medications you take. They may also check your body and order tests like blood work to make sure you’re healthy enough for the procedure.

Placement procedure

If you’re deemed a good candidate for a gastric balloon, the next step is the placement procedure. This is typically done as an outpatient procedure, meaning you can go home the same day.

During the placement procedure, you’ll be given a sedative to help you relax. Then, your healthcare provider will insert a deflated balloon through your mouth and into your stomach using an endoscope, which is a long, flexible tube with a camera on the end.

Once the balloon is in place, it will be filled with a sterile saline solution. This will make it expand and take up space in your stomach, helping you feel full more quickly and eat less. The entire procedure usually takes about 30 minutes to an hour.

Aftercare and follow-up

After the placement procedure, you’ll need to follow some guidelines for aftercare and follow-up. These may include:

  • Following a liquid or soft food diet for a few days after the procedure
  • Taking medications to help manage any discomfort or nausea
  • Drinking plenty of water to stay hydrated
  • Avoiding strenuous activity for a few days
  • Attending regular follow-up appointments with your healthcare provider to monitor your progress and make sure the balloon is working as it should

Your healthcare provider will give you detailed instructions on what to do and what to avoid after the procedure. It’s important to follow these instructions carefully to ensure the best possible outcome.

Conclusion

Gastric balloons can be an effective tool in weight loss for those who meet the criteria and follow the necessary aftercare. But, it’s important to consider the potential risks and side effects before making a decision. Consultation with a healthcare provider can help determine if a gastric balloon is the right weight loss solution for you.
