In this guide, you will learn everything you need to know about gastric bypass surgery, including how it works, the associated risks, the recovery process, dietary changes, and much more. Read it carefully to discover how this life-changing procedure can help you achieve sustainable weight loss and improve your overall health.

What is Gastric Bypass Surgery?

Gastric bypass surgery is a type of bariatric surgery which is a weight loss surgery that helps people with obesity to lose weight and also improve their health. However, surgery makes your stomach smaller and connects it directly to your small intestine by bypassing a part of your digestive tract.

Why the Procedure is Performed?

Weight loss surgery also known as metabolic and bariatric surgery is a surgical option if you have moderate to high-risk obesity and have not been able to lose weight by diet or exercise.

Additionally, healthcare providers often use BMI and health conditions like type of diabetes and high blood pressure to determine which people are most likely to benefit from MBS.

However, gastric bypass surgery isn’t a quick solution to treat obesity but it will change your lifestyle. After surgery, you have to eat healthy foods, control portion sizes of what you eat, and exercise. Yet if you don’t follow these guidelines then you may experience some complications after surgery and poor weight loss.

Types of Gastric Bypass Surgery

Additionally, there are types of gastric bypass surgeries which include:

Roux-en-Y gastric bypass

It's a type of gastric bypass surgery in which is small pouch is created by stapling the stomach which limits the amount of food it can hold.

Biliopancreatic diversion with duodenal switch (BPD/DS)

It’s an uncommon weight loss approach which is performed in two steps:

• At first, 80% stomach is removed which results in a tube-shaped stomach.
• The second step involves changing the digestive tract by connecting the end part of the intestine directly to the duodenum.

Single-anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S)

In this type, the small intestine is closed off just below the newly formed stomach sleeve, and the new opening below the new stomach is then connected to a section of the lower small intestine.

Endoscopic duodenal-jejunal bypass

A duodenal-jejunal bypass liner is inserted from the beginning of the duodenum to the middle of the jejunum. This device redirects food to avoid certain parts of the small intestine, similar to how Roux-en-Y gastric bypass (RYGB) surgery works. 

Gastric Bypass vs. Gastric Sleeve: Which is Better?

They both are types of weight loss surgeries, but work differently. Here is the difference:

• Gastric bypass surgery helps to create a small pouch at the top of your stomach and reroutes food to the lower part of the small intestine area. Moreover, it limits how much food you can eat and how many calories you observe.
• On the other hand, in a gastric sleeve, a surgeon permanently takes out most of your stomach and staples what’s left behind in a banana-like pouch. 

Who is Gastric Bypass Surgery For?

Gastric bypass and other weight loss surgeries can be an option for you if you have the following conditions which include:

• Your BMI is 40 or higher (extreme obesity)
• When your BMI is 35 to 39.4, then you may have a serious weight problem like type 2 diabetes, high blood pressure, or severe sleep apnea. However, you may qualify for some types of weight loss surgery if your body mass index is 30 to 34 and you have a serious weight-related problem.

However, surgery isn’t an option for everyone who is severely overweight so you may need to undergo some medical guidelines for weight loss surgery.

What Are the BMI Requirements for Gastric Bypass?

Body mass index (BMI) for gastric bypass surgery may vary between different providers, yet surgery surgery may be carried out if:

• A BMI is over 35
• BMI of 30 or above and type 2 diabetes.

However, being physically stable for surgery is essential, but you also need to commit to the long-term dietary and lifestyle changes required.

Health Conditions That Gastric Bypass Surgery Can Help Manage

Gastric bypass surgery or bariatric surgery is performed to help you lose extra weight and reduce your risk of possibly life-threatening weight-related health problems which include:

• Cancers like breast, endometrial, and prostate cancer
• Heart disease and stroke
• High blood pressure
• High cholesterol level
• Nonalcoholic fatty liver disease (NAFLD)
• Sleep apnea
• Type 2 diabetes
