Gastric sleeve surgery is remarkably effective for losing weight and avoiding further complications of excessive weight. But are you aware of the risks and side effects that can happen to you during this surgery?  

If not, consider reading this article to know every detail about gastrectomy.  

Gastric sleeve surgery is a type of bariatric surgery for weight loss to avoid further complications of obesity. In this surgery, surgeons remove a substantial portion of your stomach and leave a smaller portion of the stomach called a sleeve (the shape of the sleeve is like a banana) that goes directly into the intestine. But while this surgery is so useful you might also develop some side effects too such as reactions to anesthesia, nutritional deficiencies, or malnutrition. So, this surgery is only recommended when you come under its qualification criteria and your doctor recommends it. 


There are several advantages to treating your obesity or overweight conditions with this surgery, including:  

  • Sleeve gastrectomy helps you lose weight for a longer time than other methods. How much weight you can lose depends on your lifestyle. You may lose 60% or more within two years of the surgery.  
  • It helps you avoid other complications or improve your conditions if you have them, such as heart disease, type 2 diabetes, high cholesterol, sleep apnea, infertility, or stroke.  
  • This surgery also improves your ability to do your regular daily life activities, which improves your overall quality of life.  
  • If you maintain a good diet and lifestyle, you might never develop obesity or overweight problems.  


While this sleeve gastrectomy surgery is beneficial for weight loss, it has some side effects too that you might develop during or after the surgery, including: 

During the surgery risks  

  • Excessive bleeding due to a deep cut in the abdomen.  
  • You might get an infection.  
  • Your body might develop adverse effects from anesthesia.  
  • You might develop blood clots during surgery.  
  • You might develop lung or breathing problems. 
  • Due to poor stitching, you might leak from your staple/stitches. 

After the surgery risks that happen in the short or long term 

  • You might experience problems in the gastrointestinal tract.  
  • You might develop hernias due to weakened abdomen tissue.  
  • Malnutrition, because you are not able to consume nutritious food, and the body loses its ability to absorb the normal amount of nutrition from the food.  
  • You might experience hypoglycemia because your body is not able to absorb the normal amounts of calories.  
  • You might experience gastroesophageal reflux. 
  •  In exceedingly rare cases, it might be fatal.  

Who is it for?  

To take the sleeve gastrectomy, you need to have these qualities in you that make you eligible for this surgery, which are as follows: 

  • You have severe obesity or a BMI (Body Mass Index) of 40 or higher, or at least a BMI of 35 with one complication of the disease.  
  • You went through all previous treatments that are used to treat obesity but didn’t get any results or got truly little results from them.  
  • You are mentally and physically prepared to have the surgery, follow the programs for recovery, and avoid complications.  

Sleeve gastrectomy is an exceptionally excellent choice for long-term weight loss. This bariatric surgery is easy to perform and has a fast recovery. But it involves risks too. So, only get this surgery done when your doctor recommends it.
