Gastric Bypass

Call (443) 481-6699

Today, there are more weight loss surgery options than ever before. One of the most common is gastric bypass.

Wondering if gastric bypass or another bariatric surgery might be right for you? Attend one of our many free weight-loss surgery seminars to learn more.

The Benefits of Gastric Bypass Surgery

Patients who have gastric bypass surgery typically lose 65-70% of their excess body weight within the first 12 months. Statistically, it is the most effective weight-loss surgery.

In addition to weight loss, gastric bypass can reduce chronic conditions that commonly accompany obesity, such as type 2 diabetes, high blood pressure and obstructive sleep apnea. In the long run, you can save money on prescription drugs, doctor visits and hospital stays.

How Gastric Bypass Works

Laparoscopic gastric bypass is an effective, permanent option for weight-loss surgery.

For this procedure, your surgeon creates a small stomach pouch and directly attaches it to a lower section of your small intestine.

With a smaller stomach pouch, you feel full sooner and stay full longer. As you eat less food, your body stops storing excess calories and starts using its fat supply for energy.

Gastric bypass surgery doesn't change the way your body digests food. Instead, food spends less time in the small intestine, which may help reduce the amount of fat and calories your body absorbs. The surgery also changes the way some of your hormones work, which can lessen your hunger.


How One-Anastomosis Gastric Bypass Works

Luminis Health is the only program in Maryland to offer one-anastomosis gastric bypass, a variation on gastric bypass. It is the newest form of weight loss surgery.

Using a stapling device, your surgeon creates a small pouch from the stomach and connects it to the small bowel. Unlike in gastric bypass, there is only one connection to the small intestine. This makes the procedure less invasive and requires less time in the operating room. After the surgery, patients feel fuller faster and absorb less fat and fewer calories.

Why Choose Luminis Health

We use laparoscopic techniques, which means minimal scarring, less pain and shorter hospital stays.

And once your surgery is complete, we continue to offer support, since this is a lifelong journey. We'll help set you up for success by teaching you about:

  • Making healthy choices when away from home.
  • Reading food labels.
  • Staying hydrated.
  • Identifying low-fat foods.

Our Bariatric Optimization Program (BOP) is a personalized, medically supervised fitness program designed with your needs in mind. It ensures you're able to incorporate exercise into your life in a healthy, sustainable way.

We also offer support groups so you can talk to other people who understand what you're going through.

Plus, if you're dealing with any other medical concerns, we have access to a wide range of specialists within Luminis Health to make sure you're getting holistic, comprehensive care. For instance, if you develop loose skin after weight loss, the Luminis Health Plastic Surgery team can talk to you about options for body contouring.

What to Expect: Before and After the Procedure

We offer nutrition classes before and after surgery that arm you with the resources you need. You'll be paired with a dietitian who creates personalized diet plans and meal planning strategies based on your condition and surgery date. Through BOP, you'll get exercises to do before surgery.


After your surgery, your stomach needs time to adjust — it's undergone a lot of changes. You move from a liquid diet to pureed foods to soft foods over the course of about a month. Your doctor provides you with specific instructions on what to eat and drink.


Once you transition back to solid foods, you still need to eat differently than you did before surgery. Because your stomach is smaller, you have to commit to small, nutrient-rich meals moving forward.
