SADI in Nashville, Tennessee

Single Anastomosis Duodeno-Ileal Bypass with Sleeve, commonly known as SADI, is a newer, advanced bariatric surgery that combines two approaches: a sleeve gastrectomy and a simplified intestinal bypass. In this procedure, a large portion of the stomach is removed to create a smaller “sleeve,” and the small intestine is rerouted to reduce calorie and nutrient absorption. This combination makes SADI one of the most powerful options for long-term weight loss.

Because it addresses both how much food you can eat and how your body processes it, SADI is especially effective for patients with higher BMIs or those who need greater results after trying other weight loss methods. For many, this surgery not only leads to significant and sustained weight loss but also helps improve the management of obesity-related conditions such as type 2 diabetes and sleep apnea.

Amazing results are achieved with the right plan!

How SADI Works

SADI combines the benefits of a sleeve gastrectomy with a simplified intestinal bypass. First, a large portion of the stomach is removed, leaving a smaller, sleeve-shaped stomach that limits how much food you can eat. Then, the small intestine is rerouted so that fewer calories and nutrients are absorbed. This dual approach—restriction plus malabsorption—makes SADI one of the most powerful tools for long-term weight loss.

Because it targets both appetite control and calorie absorption, patients often achieve greater and more sustained weight loss than with restrictive procedures alone. For many, it also leads to improvements in obesity-related conditions, such as type 2 diabetes, sleep apnea, and hypertension.

Who Is It For?

SADI may be recommended for patients who need stronger results than a sleeve or bypass alone can provide. It may be considered if:

Your BMI is significantly above 35 and obesity is affecting your health.
You live with conditions like type 2 diabetes, sleep apnea, or high blood pressure that are difficult to control at higher weights.
You have not achieved lasting results from a previous bariatric procedure and need a more powerful option.

This surgery is often chosen by patients seeking the most effective option for significant weight loss and long-term health management, with the commitment to follow lifelong nutritional guidance and regular follow-ups.

Patient Journey

Step 1

Candidacy and Evaluation

Your first visit begins with a full review of your medical history, weight loss struggles, and long-term goals. Dr. Jameil Abou-Hanna and our team use this information to decide if SADI is the right match for your health profile.

Step 2

Pre-Surgery Clearances

You’ll meet with a dietitian to build a nutrition plan, discuss vitamins, and prepare your body for surgery. A medical assessment confirms you’re physically ready, while a psychological evaluation ensures you’re equipped for the lifestyle changes that follow.

Step 3

Virtual Support Group

All patients are invited to join our free virtual support group, where members share their weight loss experiences. Hosted on Zoom every second Tuesday of the month, it’s a place to learn from others, ask questions, and stay motivated throughout your journey.

Step 4

Qualification for Surgery

Once your evaluations and clearances are complete, our team reviews everything to make sure SADI is safe and tailored for you. At this stage, you’ll receive detailed pre-op instructions so you’re fully prepared for surgery day.

Pre-Op Preparation

Before SADI surgery, patients follow a structured plan to make the operation safer and recovery smoother. A low-calorie, high-protein diet is started 1–2 weeks beforehand to shrink the liver, which often enlarges with obesity. This makes the surgery easier and lowers complication risks.

You’ll also begin vitamin supplements, focus on hydration, and practice small lifestyle changes that prepare you for the long-term adjustments after surgery. These steps are more than a checklist—they’re the foundation for lasting results.

Post-Op Recovery

Recovery after SADI is a step-by-step process that allows your body to heal while adjusting to both a smaller stomach and reduced calorie absorption. Most patients spend a short time in the hospital, where walking is encouraged within the first 24 hours to support circulation and speed healing. In the first weeks, the focus is on rest, hydration, and slowly reintroducing liquids before progressing to pureed and then soft foods. As energy returns, light activity and a gradual return to work are possible, with ongoing support from our team. Because SADI alters how your body absorbs nutrients, daily vitamins, protein, and regular follow-up visits become a permanent part of your care. With these supports in place, patients typically see steady weight loss and improvements in obesity-related conditions over the following months.
