The Different Types of Bariatric Surgery

There are different surgical options available depending on your situation and the recommendation of your surgeon. While Doctors have experience performing hundreds of these procedures, every surgery has risks and patient education is important.

Gastric Bypass

How it works to help you lose weight:


The gastric bypass limits food and keeps it from being absorbed completely, it is the most frequently performed bariatric and metabolic procedure in the United States since the late 1960’s. This technique alters the complex relationship your body has with food and its metabolism. This positive change helps reset your body’s ability to effectively manage weight. The surgery allows the body to establish a new, lower, healthier body fat set point.


The procedure creates a stomach pouch that significantly reduces overall stomach size and the amount of food it can hold. The pouch is surgically attached to the middle of the small intestine, thereby bypassing the rest of the stomach and the upper portion of the small intestine (duodenum). The smaller stomach size helps patients feel full more quickly, which reduces food intake. Bypassing part of the intestine limits calorie absorption.


The operation is usually done in two hours or less. Most patients have a two to three day hospital stay and return to full activity in two to six weeks.



  • Limits the amount of food that can be eaten and reduces the desire to eat.
  • Average excess weight loss is higher than with most other surgeries including Sleeve Gastrectomy.
  • Can resolve type 2 diabetes by 68%, high blood pressure by 66%, obstructive sleep apnea by 76%, and improve high cholesterol by 95%.


  • When removing or bypassing the pylorus, a condition known as DUMPING SYNDROME can occur as the result of rapid emptying of stomach contents into the small intestine. This is triggered when too much sugar or large amounts of food are consumed. While not a risk to your health the results can be very unpleasant and include: sweating, nausea, weakness, flushing skin, rapid heart rate, dizziness, low blood pressure, vomiting, diarrhea, and faintness. Dumping syndrome lasts 20-30 minutes and then goes away. This provides the patient plenty of time to reflect on the food choices and behavior they made to led to the episode. For most patients the fear of dumping syndrome helps them make better food choices.
  • Because the duodenum is bypassed, poor absorption of iron and calcium can result in the lowering of total body iron and a predisposition to iron deficiency anemia. Women should be aware of the potential for heightened bone calcium loss.
  • Bypassing the duodenum has caused metabolic bone disease in some patients, resulting in bone pain, loss of height, humped back and fractures of the ribs and hip bones. All of the deficiencies mentioned above, however, can be managed through proper diet and vitamin supplements.
  • Chronic anemia due to vitamin B12 deficiency can occur. This can usually be managed with vitamin B12 pills or injections.
  • Rerouting of bile, pancreatic and other digestive juices beyond the stomach can cause intestinal irritation and ulcers


Sleeve Gastrectomy

How it works to help you lose weight:

A sleeve gastrectomy is a procedure that limits the amount of food you can eat by reducing the size of your stomach. Like other metabolic surgeries, it also helps to establish a lower, healthier body fat set point by changing the signals between the stomach, brain, and liver.


The procedure creates a small stomach “sleeve” using a stapling device. This sleeve will typically hold 50 mL to 150 mL and is about the size of a banana. The rest of the stomach is removed. The procedure greatly reduces the size of the stomach and limits the amount of food that can be eaten at one time. It does not cause decreased absorption of nutrients or bypassing the intestines. 


The operation is usually done in one to two hours or less. Most patients have a two to three day hospital stay and return to full activity in two to four weeks.



  • Limits the amount of food that can be eaten at a meal.
  • Food passes through the digestive tract in the usual order, allowing vitamins and nutrients to be fully absorbed into the body.
  • Can resolve type 2 diabetes by 45%, high blood pressure by 49%, obstructive sleep apnea by 60%, and improve high cholesterol by 77%.


  • Complications due to stomach stapling, including separation of tissue that was stapled or stitched together and leaks from staple lines.
  • Ulcers
  • Dyspepsia, a vague discomfort in the upper abdomen or chest described as gas, feeling of fullness, gnawing or burning.
  • Heartburn or gastrointestinal reflux
