Introduction

The rise of glucagon-like peptide-1 (GLP-1) receptor agonists like Ozempic® and Wegovy® has revolutionized weight management and diabetes treatment, offering remarkable results in appetite suppression and blood sugar control. However, as with any medication, there are considerations to keep in mind, especially when it comes to surgical procedures. A common question arises: Do you need to stop GLP-1 before surgery?

This question is particularly pertinent as recent studies indicate that the traditional guidelines recommending a seven-day cessation period before surgery may not be as applicable as previously thought. Research has shown that while GLP-1 medications do have an effect on gastric emptying, the actual implications for surgical safety may not necessitate such extensive holds.

In this blog, we will explore the latest findings on the management of GLP-1 medications before surgery, the rationale behind current recommendations, and what patients should consider when preparing for surgical procedures. By the end of this post, you will have a comprehensive understanding of the implications of continuing GLP-1 therapy around the time of surgery, along with guidance on how to approach your health care team about your treatment plan.

The Role of GLP-1 Medications

GLP-1 medications are increasingly popular due to their effectiveness in managing obesity and type 2 diabetes. They work by enhancing insulin secretion, inhibiting glucagon release, and slowing gastric emptying, which contributes to a feeling of fullness. However, this delay in gastric emptying has raised concerns about potential complications during surgeries, particularly related to the risk of aspiration.

Studies have shown that the gastric emptying delay caused by GLP-1 medications can potentially lead to retained food contents in the stomach. This situation could raise the risk of regurgitation and subsequent aspiration into the lungs during anesthesia, which can be life-threatening. As a result, the American Society of Anesthesiologists (ASA) has traditionally recommended that patients discontinue these medications for a period before undergoing surgery.

However, as we explore further in this post, recent research challenges this standard practice.

Current Recommendations and Their Rationale

Historical Context

Historically, the ASA’s guidelines advocated for a seven-day cessation of GLP-1 medications before any surgical or endoscopic procedures. This recommendation was based on concerns about aspiration risks due to delayed gastric emptying. The rationale was that an empty stomach would reduce the risk of complications during procedures requiring anesthesia.

Despite these guidelines, there has been little empirical data supporting the need for such a long hold. The recommendation’s foundation was primarily anecdotal and based on limited studies that did not comprehensively assess the effects of GLP-1 medications on gastric emptying in surgical contexts.

Emerging Evidence

Recent studies, including a meta-analysis led by Dr. Thomas McCarty at Houston Methodist Hospital, suggest that the delay in gastric emptying caused by GLP-1 medications is relatively minor—approximately 36 minutes for solid foods. This finding raises questions about the necessity of a lengthy cessation period, particularly when considering the implications for patients who rely on these medications for diabetes management or weight loss.

Moreover, delaying medication can significantly impact blood glucose control in diabetic patients. The meta-analysis indicates that holding GLP-1 medications for a week can lead to hyperglycemia, which poses its own risks during surgical procedures.

A Shift in Guidelines

The emerging consensus from recent studies is that not all patients need to stop GLP-1 medications before surgery. In fact, many patients can safely continue their GLP-1 therapy, especially if they do not exhibit significant gastrointestinal side effects.

For patients with a higher risk of complications, such as those experiencing nausea or bloating, an individualized approach should be taken. This may include a liquid diet for 24 hours before the procedure or the use of gastric ultrasound to assess stomach contents prior to anesthesia.

Individualized Assessments: The Key to Safety

Understanding Patient Risk Factors

When it comes to surgical procedures, one size does not fit all. Each patient brings unique factors that can influence the decision to continue or discontinue GLP-1 therapy. These factors can include:

• Medical History: Patients with a history of gastrointestinal issues or delayed gastric emptying may need to take extra precautions.
• Current Symptoms: If a patient is experiencing nausea, vomiting, or other gastrointestinal discomfort, it is essential to address these symptoms prior to surgery.
• Type of Surgery: The nature of the surgical procedure may also dictate the need for adjusting medication. For example, procedures that involve general anesthesia may warrant more caution than those performed under local anesthesia.

Collaboration with Healthcare Providers

To navigate the complexities of managing GLP-1 medications around the time of surgery, open communication with healthcare providers is essential. Patients should:

• Inform Their Healthcare Team: Ensure that all members of the surgical team are aware of the medications being taken. This includes anesthesiologists, surgeons, and primary care providers.
• Discuss Concerns: Patients should feel empowered to discuss any concerns about their medications and the potential risks associated with continuing them during the perioperative period.
• Follow Recommended Protocols: If advised to follow a liquid diet or undergo additional assessments, it is crucial to adhere to these recommendations to minimize risks.

What Happens If You Don’t Stop GLP-1 Before Surgery?

Potential Risks

Continuing GLP-1 therapy without any modifications before surgery can lead to several risks, including:

• Aspiration Pneumonia: If gastric contents are present during anesthesia, there is a risk of aspiration, which can result in serious complications.
• Delayed Emergence from Anesthesia: Retained gastric contents can complicate anesthesia management and lead to prolonged recovery times.
• Hyperglycemia: For patients with diabetes, withholding GLP-1 medications can result in elevated blood glucose levels, increasing the risk of surgical complications.

Mitigating Risks

If GLP-1 medications are not stopped before surgery, anesthesiologists can employ strategies to mitigate risks, including:

• Full-Stomach Precautions: Using predetermined doses of anesthetics to account for the possibility of retained gastric contents.
• Postoperative Monitoring: Close monitoring of patients post-surgery to assess any complications related to anesthesia and medication.

Resuming GLP-1 Therapy After Surgery

One frequently asked question is when patients can safely resume their GLP-1 medications after surgery. Generally, most patients can resume their medications on the same day of the procedure or shortly after, depending on their recovery and any guidelines provided by their healthcare team.

For patients on daily dosing, scheduling surgery on the same day they typically take their medication can help ensure they do not miss a dose. For those on weekly dosing, it may be advisable to align surgical schedules with their medication regimen to avoid delays in treatment.

Conclusion

Navigating the intricacies of GLP-1 medications before surgery can be complex, but it is clear that recent findings challenge the need for an extended hold period. By understanding the implications of these medications and collaborating with healthcare providers, we can ensure patient safety while also maintaining effective management of weight and blood sugar levels.

As we continue to explore the evolving landscape of GLP-1 therapy, it is essential to approach surgical preparations with individualized care and attention to the unique needs of each patient.

If you’re considering surgery and currently taking GLP-1 medications, we encourage you to take proactive steps in discussing your treatment plan with your healthcare team to ensure a safe and effective approach.
