Your Partner in Weight Loss

The Beebe Center for Weight Loss Surgery is a place where our patients find a partner in their weight loss journey. Many patients have tried to treat this on their own with diet and exercise. In some cases, patients have not had success losing the amount of weight they need to with diet and exercise alone, that is where our team comes in. We are here to help you.

Talk to your primary care provider about weight loss surgery and how you can be referred to Beebe's Center for Weight Loss Surgery.

Those who are interested in joining the practice for their life-changing surgery, can set up a virtual consultation or get more information by requesting a consultation.

What is Obesity?

Obesity is a complex disease involving an excessive amount of body fat. Obesity isn't just a cosmetic concern. It is a medical problem that increases your risk of other diseases and health problems, such as heart disease, diabetes, high blood pressure and certain cancers.

There are many reasons why some people have difficulty avoiding obesity. Usually, obesity results from a combination of inherited factors, hormonal imbalances, combined with the environment and personal diet and exercise choices.

Obesity is diagnosed by a healthcare provider and is classified as having a body mass index (BMI) of 30 or greater. Nearly 40 percent of Americans have obesity.

Obesity is:

  • A disease
  • A worldwide health concern
  • Caused by many factors
  • Treatable and manageable.

Obesity is not:

  • Your fault
  • Due to lack of willpower
  • Yours to manage alone
  • Just about food
  • Cured by a miracle treatment.

If you are struggling with making the lifestyle changes necessary to succeed at losing weight, bariatric surgery may be an option for you. Beebe Healthcare offers a comprehensive approach to weight loss through our advanced bariatric surgery program. We offer a multi-disciplinary approach to losing weight and keeping it off.


Understanding Body Mass Index (BMI)

Body fat is hard to measure directly. So it is often measured by body mass index (BMI). BMI measures weight related to height. It is a common way to measure body fat and is one tool healthcare providers use when talking about weight.

Causes of Obesity

Better understanding the causes of obesity can help you better treat obesity. Talk with your healthcare provider about your daily habits, medical history and family medical history to determine the best treatment plan for you.

  • Obesity is a complicated disease
  • Obesity has more than one cause
  • Obesity is not just about food
  • Obesity is not someone's fault
  • Weight management can be challenging if troubled by stress and other concerns.
  • You need to work on these issues to be successful in your weight management.
  • An imbalance of calories in and calories burned may cause weight gain.
  • Long daily commutes and desk jobs make it harder to get physical activity.
  • Not all communities have safe spaces to run, bike, or walk.
  • Small bouts of increased physical activity throughout the day can be beneficial.
  • Some studies show a link between how much people sleep and how much people weigh.
  • In general, people who do not get enough sleep may weigh more than people who do.
  • Your body has hormones (chemicals in your body that control function and activity of tissues and organs) that help let you know if you are hungry or full.
  • The hormones that signal hunger and fullness do not always work in people with obesity.
  • Genes in your body can determine if you are more likely to have obesity.
  • Having these genes is not a reason to give up on losing weight. Weight loss as small as 5% can improve your overall health.
  • Some prescription medications can cause weight gain of up to several pounds each month.
  • Do not stop taking medications you think might be causing weight gain, but speak with your healthcare provider about other medication options.
  • We are surrounded by television ads, billboards, and images that promote the consumption of foods and beverages that are high in calories and fat.
  • Some neighborhoods have little or no access to fresh, healthy foods.

Commonly Asked Questions About Weight Loss Surgery

Beebe's Center for Weight Loss Surgery is here with you every step of the way. If you decide to have weight loss surgery, you will have your appointments in our Georgetown office before and after surgery. Your surgery will be performed by our advanced surgery team at the Margaret H. Rollins Lewes Campus. Your care team will explain everything to you during your appointments.

Obesity is a major health crisis in our country. There are several obesity-related health conditions that are associated with obesity. These conditions often lead to a decreased quality of health and life of those affected. Below you will find a list of obesity-related conditions. It is important to talk with your doctor about these conditions.

  • Cancer: Recent studies suggest that those with a BMI more than 40 (severe obesity) had death rates from cancer that were 52% higher for men and 62 % higher for women, as compared to rates for normal-weight men and women. In both men and women, higher BMI is associated with higher death rates from cancers of the esophagus, colon and rectum, liver, gallbladder, pancreas, and kidney. The same trend applies to cancers of the stomach and prostate in men, and cancers of the breast, uterus, cervix, and ovaries in women.
  • Diabetes: Diabetes is a life-long disease marked by high levels of sugar in the blood. Among those diagnosed with type 2 diabetes, 67 percent have a BMI greater than 27 and 46 percent have a BMI greater than 30.
  • Gallbladder Disease
  • Heartburn
  • Heart Disease
  • High Cholesterol
  • High Blood Pressure
  • Osteoarthritis or Joint disease
  • Depression: Depression may be described as feeling sad, blue, unhappy, miserable, or down in the dumps. Most of us feel this way at one time or another for short periods. True clinical depression is a mood disorder in which feelings of sadness, loss, anger, or frustration interfere with everyday life for an extended time.
  • Sleep Apnea: Sleep apnea is a condition characterized by episodes of stopped breathing during sleep.
  • Stroke: A stroke occurs when a blood vessel (artery) that supplies blood to the brain bursts or is blocked by a blood clot. Within minutes, the nerve cells in that area of the brain are damaged, and they may die within a few hours. As a result, the part of the body controlled by the damaged section of the brain cannot function properly.

Weight-loss surgery for obesity may be considered if you have tried other methods to lose weight that haven't worked and:

  • You have BMI of 40 or higher
  • Your BMI is 35 to 39.9, and you also have a weight-related health problem, such as diabetes, high cholesterol, fatty liver disease, sleep apnea or high blood pressure
  • You're committed to making the lifestyle changes that are necessary for surgery to work
  • Age 18-69

Many patients with obesity have tried to treat this on their own, with diet and exercise. Many have had some success, only to have weight regain. More often, patients have little to no success with diet and exercise alone. This is not a result of lack of willpower or the wrong diet.

When a patient has a BMI> 35, their chances of reaching a normal body weight for a lasting period of time is less than 1%. That’s why surgery is an option for patients with severe obesity. Unfortunately, many patients who could benefit from surgery don’t know if surgery is right for them.

Weight loss surgery does not just treat the disease of obesity, but it treats other conditions like diabetes, heart disease, high blood pressure, arthritis, high cholesterol, sleep apnea, and acid reflux. In addition, surgery greatly reduces the risk of death from cancer, diabetes, heart disease, and other diseases.

Weight loss surgery, causes changes in appetite, satiety (feeling full), and metabolism (how the body burns calories). Many of the hormonal signals that cause weight gain or inability to lose weight are affected by these procedures, and it becomes easier to lose weight.

Around 90% of patients after bariatric surgery lose 50% of excess body weight and keep this extra weight off long-term. 

When patients start to lose weight after surgery, they also feel more energetic, less pain, and more enthusiasm for doing things they have not done in years. The significant and rapid weight loss after surgery can lead to changes in hormones and lead to even more weight loss.

At Beebe we offer the following bariatric surgeries:

  • Gastric sleeve: In this procedure, part of the stomach is removed to make it smaller and reduce your meal size. The part that is removed contains hormones that make you hungry. Consequently, after surgery, most patients have appetite suppression. This surgery takes approximately 30-45 minutes
  • Gastric bypass surgery: In gastric bypass (Roux-en-Y gastric bypass), the surgeon creates a small pouch at the top of your stomach. The small intestine is then rerouted to decrease the amount of calories you can absorb.
  • Biliopancreatic diversion with duodenal switch: This procedure begins with the surgeon performing a sleeve gastrectomy and then rerouting the small bowel to decrease the amount of calories absorbed. This procedure is typically offered to patient with BMI of 50 or more. It is also offered to patients with BMI of 35 or more and history of sleeve gastrectomy
  • Revision surgery: We offer revision surgery for sleeve and gastric bypass patients to help with more weight loss or to treat heartburn/reflux after surgery.

Most surgeries are performed with half inch incisions (Laparoscopically or robotically) which results in less pain and faster recovery.

Patients spend 1-2 nights in the hospital and may return to work within 1-2 weeks. Some patients may be able to go home the same day of the surgery. Patients will be able to resume most daily activities by the time they are discharged from the hospital.
