Comparison of Gastric Bypass Surgery and Sleeve Gastrectomy for Weight Loss

Gastric bypass surgery and sleeve gastrectomy surgery are bariatric surgeries or weight loss surgeries that help reduce the size of your stomach and restrict the intake of food. 

There are several key differences and similarities between these two surgeries, and knowing which will help you choose the most appropriate one.

Difference Between Sleeve Gastrectomy and Gastric Bypass Surgery

Both sleeve gastrectomy and gastric surgery reduce your stomach size and restrict the amount of food you can eat before you feel full. 

The main difference between the two surgeries is in the procedure the surgeon uses to create the new stomach pouch. 

In sleeve gastrectomy, the surgeon permanently removes about 80% of your stomach and sews the remaining part into a small banana-shaped stomach pouch. No other changes are made to your organs. 

On the other hand, in gastric operation, the surgeon first creates a small stomach pouch by removing most of your stomach as well as the first part of your small intestine and then reconnects the newly created stomach pouch to the remaining small intestine. 

The removed portion of the stomach is also connected further down to the small intestine, so it still provides the necessary acids and digestive enzymes.

The portion that’s removed from the stomach and intestine in this procedure typically absorbs nutrients and calories. Now, since food no longer passes through this section, these calories are not absorbed, leading to weight loss.  

At KCM Clinic, expert bariatric surgeons are available to perform both these procedures. Both laparoscopy and open surgery techniques are available at the clinic to provide the most appropriate treatment.

Difference in Recovery

Gastric bypass surgery is more complicated than sleeve gastrectomy surgery. While sleeve gastrectomy involves only one step, gastric bypass surgery needs two steps. Therefore, recovery time in the case of gastric bypass surgery is slightly longer than in sleeve gastrectomy surgery.

Risks and Complications of Gastric Bypass Surgery and Sleeve

All bariatric surgeries are relatively safe procedures. The risk of developing major complications is very less, and when compared with obesity-related health issues, they are considered minimal. 

However, just like any surgery, sleeve gastrectomy and gastric bypass surgery come with their own share of risks and complications.

Some common complications of sleeve gastrectomy include gastroesophageal reflux disorder (GERD), narrowing along the stomach pouch, stomach obstruction, etc. 

Complications from gastric bypass surgery may include stomach perforation, stomach ulcers, bowel obstruction, etc.

At KCM Clinic, the main aim of the doctors is to reduce the complications after the surgery and provide the best post-operative care.

Some More Key Differences Between Sleeve Gastrectomy & Gastric Bypass Surgery

• Gastric bypass surgery may help you lose more weight.
• Sleeve gastrectomy usually includes fewer complications.
• Sleeve gastrectomy has a faster recovery time.
• Sleeve gastrectomy is less likely to cause dumping syndrome.
• Gastric bypass surgery is less likely to cause gastroesophageal reflux disorder.
• Gastric bypass surgery may reduce the absorption of a greater amount of calories.

A Final Word

Both sleeve gastrectomy and gastric bypass surgery are beneficial for treating obesity. The doctors at KCM Clinic will help you choose the best surgery.
