Roux En-Y Gastric Bypass in Nashville, Tennessee

Roux-en-Y Gastric Bypass, often called gastric bypass, is one of the most established and effective bariatric surgeries available today. In this procedure, the surgeon creates a small stomach pouch and connects it directly to the small intestine, bypassing a portion of the digestive tract. With a smaller stomach and fewer calories absorbed, patients achieve powerful weight loss while also seeing improvements in obesity-related conditions.

Unlike sleeve gastrectomy, gastric bypass combines restriction (limiting how much you can eat) with malabsorption (reducing how many calories and nutrients your body absorbs). This makes it especially effective for patients with higher BMIs or conditions such as type 2 diabetes. For many, gastric bypass represents a proven path toward lasting weight loss and better overall health.

Amazing results are achieved with the right plan!

How Gastric Bypass Works

The gastric bypass works in two powerful ways. First, it creates a smaller stomach pouch, so you feel full after eating much less food. This is called restriction, and it helps patients control portion sizes without constant hunger. Second, the new pouch is connected directly to a lower part of the small intestine, bypassing a portion of the digestive tract. This causes malabsorption, meaning your body absorbs fewer calories and nutrients from food.

By combining restriction and malabsorption, gastric bypass not only supports significant weight loss but also helps with the management of conditions like type 2 diabetes. Many patients find that this dual approach makes it easier to lose weight and improve their overall health in the long run.

Who Is It For?

Roux-en-Y Gastric Bypass is often a good option for patients who need a stronger intervention than restrictive procedures alone. It may be considered if:

Your BMI is over 35 and obesity is affecting your health.
You have type 2 diabetes, sleep apnea, or high blood pressure that are difficult to manage at a higher weight.
You want a procedure with proven, long-term results that goes beyond portion control.

This surgery is designed for people who are ready to make lasting lifestyle changes and need a procedure that offers both substantial weight loss and improved management of obesity-related conditions.

Patient Journey

Step 1

Candidacy and Evaluation

Your journey begins with a detailed consultation with Dr. Jameil Abou-Hanna. Together, we’ll review your medical history, current health challenges, and weight loss goals. This step helps confirm whether gastric bypass is the right match for your needs and ensures you feel informed from the start.

Step 2

Clearance and Visits

Before surgery, you’ll complete a series of visits designed to set you up for success. Our dietitian will guide you through nutrition planning, vitamins, and meal preparation for the weeks ahead. A full medical exam checks your readiness for surgery, while a psychological evaluation ensures you’re prepared for the lifestyle changes that follow.

Step 3

Virtual Support Group

As part of your preparation, you’ll be welcomed into our free virtual support group. Held on Zoom every second Tuesday of the month, this group connects you with other patients who openly share their experiences with bariatric surgery. It’s a place to ask questions, hear real stories, and gain encouragement before and after your procedure.

Step 4

Qualification for Surgery

In the weeks leading up to your procedure, all evaluations—medical, nutritional, and psychological—are carefully reviewed. This final step confirms you’re cleared for gastric bypass and that the procedure is tailored to your health profile. Once approved, you’ll receive detailed instructions to help you prepare for surgery day with confidence.

Pre-Op Preparation

Preparing for gastric bypass starts before you ever enter the operating room. In the weeks leading up to surgery, you’ll follow a special high-protein, low-calorie diet designed to shrink the liver. Since the liver often enlarges with obesity, reducing its size makes it easier for the surgeon to safely reach the stomach and lowers the chance of complications.

This stage is also about laying the groundwork for life after surgery. You’ll receive guidance on vitamins, hydration, and meal planning, along with lifestyle adjustments that set you up for long-term success. These preparations aren’t just short-term requirements—they’re the first step in building the habits that will carry you through recovery and beyond.

Post-Op Recovery

Healing after gastric bypass takes time, but it follows a clear path. The goal is to let your body recover while helping you adjust to eating smaller amounts and absorbing fewer calories. Because bypass combines restriction and malabsorption, paying attention to nutrition and supplements is especially important.

Early Recovery (First 2 Weeks)

Most patients spend 1–2 days in the hospital for monitoring.
Walking within 24 hours helps circulation and speeds recovery.
Pain is controlled with medication, and clear liquids are introduced gradually.
The main focus is hydration, gentle movement, and rest.

Adjustment Phase (Weeks 3–6)

Diet shifts from pureed foods to soft meals, eaten slowly in very small portions.
Daily vitamins and supplements become part of your routine.
Light activity and a return to work are possible, depending on how you feel.
Protein intake and hydration remain top priorities.

Long-Term Recovery (After 6 Weeks)
