GLP-1 Medications and Bariatric Surgery: What You Need to Know

Bariatric surgery is not about “taking the easy way out.” Rather, it’s a metabolic intervention that changes how your body regulates hunger, fullness, blood sugar and energy balance.

For many patients, especially those who have struggled for years despite doing “all the right things,” surgery helps correct underlying biology, not just behavior.

Surgery may be the right fit if you:

• Have a BMI that is either
  • Greater than 40, or
  • Greater than 35 with obesity-related conditions (like diabetes, sleep apnea or high blood pressure)
• Have tried diet, exercise and/or medications without lasting success
• Are looking for a long-term, sustainable solution
• Want to significantly improve or resolve chronic conditions

Bariatric surgery delivers more than weight loss; it improves overall health and quality of life in ways that many patients don’t expect.

Key benefits include:

• Substantial, durable weight loss
• Improvement or resolution of conditions like type 2 diabetes, hypertension and sleep apnea
• Reduced risk of heart disease and stroke
• Decreased risk of cancer
• Improved mobility, energy and mental health
• Hormonal changes that reduce hunger and cravings

One of the biggest misconceptions is that surgery is a short-term fix. In reality, it has some of the strongest long-term data of any obesity treatment.

• Patients typically lose 25% to 35% of their total body weight, depending on the procedure.
• Studies show durable weight loss is maintained throughout 10 years or more.
• Up to 80% of patients with type 2 diabetes see remission or significant improvement.
• Bariatric surgery is associated with reduced overall mortality and longer life expectancy.

GLP-1 medications (like semaglutide or tirzepatide) are powerful, evidence-based tools, and they absolutely have a place in obesity care.

At Mercy, we don’t view this as surgery versus medication. Instead, it’s about using the right tool, or combination of tools, for you.

GLP-1 medications may be used to:

• Help patients lose weight before surgery to reduce risk
• Support patients who are not ready or not candidates for surgery
• Assist with weight regain after surgery
• Serve as part of a long-term medical weight management plan

Success in bariatric care doesn’t come from a single appointment or procedure; it comes from a team-based approach.

At Mercy Cedar Rapids, your care team includes:

• A board-certified bariatric surgeon
• Providers and a doctor certified in obesity medicine
• Dietitians who specialize in sustainable wholesome nutrition and not fad diets
• Behavioral health professionals who help address habits, mindset and emotional eating
• Nurses and coordinators who guide you every step of the way

Mercy’s program offers personalized care designed to meet you where you are and help you move forward.

One of the biggest predictors of long-term success is ongoing support. That’s why the process at Mercy starts early and continues for life, beginning with patient education and active involvement in their care.

First, patients are encouraged to attend a free information seminar, where they:

• Learn about surgical and non-surgical options.
• Understand what to expect before and after surgery.
• Ask questions in a low-pressure, non-judgmental environment.

Next, if you decide you want to pursue further obesity care with us, you’ll receive:

• Further education and medical evaluations
• Optimization of your mental and physical health prior to surgery
• Nutrition counseling and goal-setting
• Clear guidance on what to expect at every stage
• Long-term follow-up for life

Then, after surgery, support continues through:

• Regular follow-up visits
• Ongoing access to dietitians and your care team
• Support groups and community resources
• Guidance for navigating real-life challenges (such as holidays, stress, plateaus and more)
• Lifelong follow-up
