The downside of gastric bypass surgery


Are you planning to have gastric bypass surgery to manage your obesity? If yes, are you aware of the risks and complications involved in this surgery? Because these risks and complications can be life-threatening.  

Read this article to know the downside of gastric bypass surgery before deciding.  

Obesity and excess weight have become major concerns of the world. According to statistics, 1 out of 3 adults (30.7%) are overweight and 2 out of 5 adults (42.4%) are obese. Similarly, 1 out of 16 children around 2-19 of age are overweight (16.1%) and 1 out of 5 children around the same age have obesity (19.3%).  

Obesity can be treated by diet and lifestyle changes but in some cases, these treatments are not remarkably effective. Then, the doctor recommends that you should have bariatric surgery. Which can help to lose weight and avoid complications.  

Gastric bypass surgery is a type of bariatric surgery where the surgeons create a small pouch from your stomach and connect it directly to the small intestine. This way, you are not able to eat more and start to lose weight. It also controls your hunger urges. But as much as it is beneficial, it has its risks and complications that you should keep in mind.  

Risks and complications 

There are several risks and complications involved with gastric bypass surgery, including: 

  • Malnutrition 
  • Stomal stenosis 
  • Dumping Syndrome 
  • Peritonitis

1. Malnutrition 

 This is the most common risk involved with gastric bypass surgery because the body is not able to get all the nutrition and vitamins that are required to maintain health. After this surgery, you are not able to consume the quantity of food you consume, and additionally, you must eat selected food items, and your body is not able to absorb all the nutrients and vitamins from the food. So, developing malnutrition is quite possible.  

To avoid this risk, you need to talk to a nutritionist and get a diet plan that helps you maintain all necessary vitamins and nutrition until you can normally consume all the food items. You can also take supplements of important vitamins and nutrients, including: 

  • Vitamin B1 
  • Vitamin B12 
  • Iron  
  • Calcium

2. Stomal Stenosis: 

This condition occurs due to the tightening and narrowing of the new opening from the stomach and small intestine after the surgery. It causes vomiting immediately after eating something.  

Stomal stenosis can easily be treated by taking immediate treatment when you first notice it to avoid further complications. If you experience vomiting after gastric bypass surgery, contact your doctor immediately.  

 3. Dumping syndrome: 

This syndrome happens to several patients after their surgery. In this syndrome, the meals get dumped directly into the small intestine from the stomach without being digested.  

There are two types of dumping syndrome: 

  • Early dumping: this type of dumping occurs within 15 -20 minutes after eating. These are the symptoms: 
      • Nausea 
      • Bloating or abdominal cramps 
      • Rapid heartbeat  
      • Sweating 
      • Fainting
  • Late dumping: this type of dumping occurs within 1 to 3 hours after eating. The symptoms you notice are: 
      • Fatigue 
      • Confusion 
      • Sweating  
      • Hunger 
      • Tremors 
      • Fainting  
      • Heart palpitations 

It can be treated by making some changes in the diet. Taking advice from a doctor or nutritionist is recommended. 

4. Peritonitis: 

This is the most serious complication of gastric bypass surgery- if there is a stomach leak that causes peritonitis to develop. In this condition, you can experience inflammation of the peritoneum, a smooth membrane of the cavity lining the abdomen.  

The symptoms you might experience in peritonitis, include: 

  • Increasing abdominal pain 
  • Hiccups 
  • Back pain 
  • Fever 
  • Rapid heart rate 
  • Restlessness 
  • Pelvic pressure 

This condition needs immediate treatment.  

Gastric bypass surgery is an excellent choice to get rid of excessive weight. But like any surgery, there are some risks involved too. So, only have this surgery when other treatments are not working on you, and you are on the verge of developing obesity complications. But before making the decision take advice from the doctor.
