How Is Non-Surgical Weight Loss Performed?
Non-surgical weight loss methods offer effective, safe, and minimally invasive solutions for individuals wishing to lose weight without surgical intervention. The most common methods include the gastric balloon and gastric Botox. Both procedures are carefully planned and performed by specialist physicians.
The Gastric Balloon Procedure is carried out under mild sedation or local anesthesia. Using an endoscope—a flexible tube with a camera at its tip—the stomach is accessed, and a silicone balloon is carefully placed. The balloon is filled with 400 to 700 milliliters of sterile saline to restrict stomach volume, providing an early feeling of fullness and reducing food intake. The procedure takes 20 to 30 minutes, and the patient is discharged on the same day. The balloon usually remains in the stomach for six months and is removed with a similar technique.
The Gastric Botox Procedure is also performed under mild sedation. The stomach is accessed using an endoscope, and botulinum toxin is injected into the antral muscles, which regulate gastric emptying. This slows down the movement of the stomach, extending the feeling of fullness and reducing appetite. The procedure only takes 15 to 20 minutes, and the patient can quickly return to daily activities. However, the effect of Botox is temporary, generally lasting three to six months, and repeated applications may be necessary.
What Are the Side Effects of Non-Surgical Weight Loss?
As with any medical procedure, methods such as gastric balloons and gastric Botox carry certain side effects and risks. These effects are generally mild and temporary; however, it is important for patients to be informed about them before undergoing the procedure.
Common side effects associated with Gastric Balloons include nausea, vomiting, abdominal pain, and gastroesophageal reflux (GERD). These symptoms can be particularly intense during the first few days but usually decrease as the body adapts. In rare cases, more serious complications such as deflation or displacement of the balloon can occur. This may cause intestinal blockage and require urgent intervention. Additionally, conditions like gastric ulcers, erosions, or esophagitis have been reported. Although the mortality rate is quite low, these complication risks should be thoroughly evaluated before the procedure.
Gastric Botox Injections are generally associated with fewer side effects. Mild abdominal bloating, cramping, or indigestion typically resolve within a few days. However, in rare cases, allergic reactions, neurological problems caused by the effect of botulinum toxin on surrounding muscles, or respiratory depression may be observed.
How Successful Is Non-Surgical Weight Loss?
Non-surgical weight loss methods provide effective options for weight loss and enhancing quality of life without the need for surgery. The most commonly used methods in this field are intragastric balloons (IGB) and gastric botulinum toxin (BTA) injections. However, the effectiveness and success of both methods can vary based on individual factors and application protocols.
- Intragastric Balloons (IGB):
Clinical studies have shown that IGBs offer significant benefits in weight loss. For instance, in a study involving the Elipse™ swallowable gastric balloon, patients lost 14.2% of their total body weight over a 4-month period. Additionally, IGBs generally provide a BMI reduction of around 2–3 kg/m². By creating an early feeling of fullness and reducing food intake, these devices facilitate weight loss. Long-term success rates increase further when combined with lifestyle changes.
- Gastric Botulinum Toxin (BTA) Injections:
Gastric Botox aims to reduce appetite and delay gastric emptying by injecting botulinum toxin into the stomach muscles. However, existing evidence indicates that its efficacy is limited. In a meta-analysis of five randomized controlled trials, BTA injections were not found to be superior to saline injections in terms of weight loss. Nonetheless, better results have been observed in individuals with a higher baseline BMI.
How to Prepare for Non-Surgical Weight Loss?
Non-surgical weight loss methods require proper preparation processes to achieve effective results. Before undergoing either the gastric balloon or gastric Botox procedures, it is crucial for patients to be physically, psychologically, and lifestyle-ready. The first step is comprehensive medical evaluation and consultation. By sharing their medical conditions, medications, and allergies with healthcare professionals, patients contribute to developing an appropriate treatment plan. Physical examinations and necessary tests determine the patient’s suitability for the procedure.
Dietary adjustments are of great importance during the preparation phase. For the gastric balloon procedure, a liquid diet is recommended for a few days before the procedure, and patients must avoid consuming food or drink after midnight the night before. A similar fasting period is advised for gastric Botox. These measures minimize the risks of complications during the procedures.
Medication management is another crucial step in preparation. Adjustments such as discontinuing blood thinners before the procedure help reduce potential risks. It is essential to follow medical advice regarding any changes to medications during this process.
What Is Postoperative Care Like After Non-Surgical Weight Loss?
Non-surgical weight loss methods require proper care and follow-up to achieve effective results. After gastric balloon or gastric Botox applications, it is important for patients to adhere to certain recommendations to protect their health and meet their goals. Mild discomfort may be experienced in the first few days as the body adapts to this new situation. These symptoms can typically be controlled with antiemetic medications and proton pump inhibitors to suppress stomach acid.
In the first week following treatment, a liquid diet is advised. With a gastric balloon, puréed and soft foods are gradually introduced as the stomach adapts to the balloon. After gastric Botox, a balanced and portion-controlled diet is organized. In both methods, small and frequent meals are preferred to increase the stomach’s tolerance capacity.
Consuming enough water is critical for supporting overall body functions and preventing nausea. Likewise, regular exercise is encouraged to optimize weight loss and maintain muscle mass. Initially, light exercises should be performed, gradually increasing their duration and intensity as time goes on.
Regular medical check-ups are essential for the early detection of potential complications and for making necessary lifestyle adjustments. Consulting with nutrition experts and obtaining psychological support during this process can increase success rates. Acute abdominal pain, deflation of the balloon, or intestinal obstruction may require emergency intervention and should be closely monitored.
