Our Summary
The research paper investigates the effects of Laparoscopic sleeve gastrectomy (LSG) - a common surgical procedure for treating obesity - on the stomach’s natural pacemaker. This pacemaker produces electrical signals that control the stomach’s movements. When part of this gastric pacemaker is removed during LSG, it could potentially lead to irregular electrical rhythms or even lack of electrical activity in the stomach, affecting recovery and symptoms post-surgery.
To understand these effects, the researchers used advanced laparoscopic mapping techniques on patients undergoing LSG surgery. They found that after the surgery, all patients either developed abnormal electrical activity in the lower part of the stomach, or their stomach’s electrical activity ceased altogether. They also found that the speed of electrical signal propagation was abnormally quick post-surgery, but the frequency and strength of signals remained the same.
In one patient who was experiencing chronic stomach issues six months after the LSG, the researchers also found an abnormal pacemaker in the lower part of the stomach.
This means that removal of the gastric pacemaker during LSG can cause long-term changes in the stomach’s electrical activity, potentially leading to chronic stomach issues. The researchers suggest that more studies should be conducted to understand the clinical implications of their findings and to explore possible treatments.

Doctor’s Tip
A doctor might tell a patient considering gastric sleeve surgery to be aware of the potential changes in their stomach’s electrical activity post-surgery, as this could impact their recovery and symptoms. They may recommend monitoring any stomach issues closely and seeking medical attention if they persist. It’s important to stay informed and communicate any concerns with your healthcare provider throughout the recovery process.
Suitable For
Patients who are typically recommended for gastric sleeve surgery include those who have a body mass index (BMI) of 40 or higher, or a BMI of 35 or higher with obesity-related health conditions such as diabetes, high blood pressure, or sleep apnea. Candidates for gastric sleeve surgery should also have tried other weight loss methods such as diet and exercise without success. Additionally, patients should be committed to making lifestyle changes post-surgery to ensure long-term success.
Timeline
Before undergoing gastric sleeve surgery, a patient typically goes through a series of consultations with healthcare professionals, including a bariatric surgeon, dietitian, and psychologist. They may also be required to follow a pre-operative diet and exercise plan to prepare their body for surgery. The patient will also undergo various medical tests and evaluations to ensure they are a suitable candidate for the procedure.
After the surgery, the patient will stay in the hospital for a few days for monitoring and recovery. They will follow a specific post-operative diet and exercise plan to help them adjust to their smaller stomach size and promote weight loss. The patient will have regular follow-up appointments with their healthcare team to monitor their progress, address any concerns, and make adjustments to their treatment plan as needed.
Over time, the patient will experience significant weight loss and improvements in obesity-related health conditions such as diabetes, high blood pressure, and sleep apnea. They may also notice changes in their eating habits, appetite, and overall quality of life. With proper adherence to lifestyle changes and ongoing support from their healthcare team, the patient can achieve long-term success with their gastric sleeve surgery.
What to Ask Your Doctor
Some questions a patient should ask their doctor about gastric sleeve surgery in light of this research:
- What are the potential risks and complications of gastric sleeve surgery, specifically in relation to changes in the stomach’s electrical activity?
- How will my stomach function differently after the surgery, and how might this impact my recovery and long-term symptoms?
- Are there any specific symptoms or warning signs I should watch out for related to changes in my stomach’s electrical activity post-surgery?
- What steps will be taken during the surgery to minimize the impact on my stomach’s natural pacemaker?
- Are there any additional tests or monitoring that will be done to assess my stomach’s electrical activity before and after the surgery?
- How will any changes in my stomach’s electrical activity be managed or treated if they occur post-surgery?
- Are there alternative weight loss procedures or treatments that do not impact the stomach’s electrical activity in the same way as gastric sleeve surgery?
- Can you provide more information on the long-term implications of changes in the stomach’s electrical activity, as highlighted in this research study?
- How often will I need follow-up appointments to monitor my stomach’s function and electrical activity after the surgery?
- Are there any lifestyle changes or dietary modifications I should consider to support my stomach’s electrical activity and overall health post-surgery?
