Obesity has become one of the top issues in many developed countries.

It is undeniable that excessive weight causes different health problems including increased mortality risk, emotional distress, and others. Most people support only natural approaches to how to lose weight and maintain yourself healthy. However, not always it is possible as there are numerous challenges. Gastric bypass (RYGB) nowadays has become more popular as it has proved its beneficence.  To understand the benefits and possible drawbacks, further information about gastric bypass might be useful.

New research from the Karolinska Institute in Stockholm shows that “RYGB improves long-term insulin sensitivity and white adipose tissue (WAT).”[1] Even people who have some weight gain have experienced benefits. The research even showed a positive effect on the prevention of diabetes.


What is gastric bypass surgery?

The aim of this surgery is to control how the stomach and small intestine handle the food you eat. The main difference after the surgical intervention is that the stomach becomes smaller and thus a person can feel full with eating less food. The bypass is made by connecting a small part of the small intestine with a small hole in the pouch. The food will travel from the pouch into the small intestine. This way a person will absorb fewer calories.

Gastric bypass benefits

  • Body mass index (BMI) decreased (a study showed that it happens within a 2-years period from 43 to 29 kg/m2[2])
  • Improved serum adiponectin (related to the regulation of glucose levels and breakdown of fatty acid). It also positively influences energy expenditure. Low levels of adiponectin have a relation to the risk of type 2 diabetes.
  • Better lipid profiles and insulin profiles.
  • Smaller fat cells. Research showed that it is linked to better insulin sensitivity. Larger but fewer fat cells have a higher risk of type 2 diabetes. After gastric bypass, research has shown a decrease in fat cell size.

After the surgery, it is still possible to experience some weight gain that is fully normal. Clients, physicians, and other specialists need to work together to achieve better results after RYGB. The research was done by Karolinska Institute also showed that RYGB showed an influence of lower BMI and other long-term improvements in metabolism for up to 5-year follow-up period. That makes me think that long-run results of staying fit are highly possible to practically any person who has done this surgery.


Gastric bypass surgery is advisable for people who are struggling with weight loss and need some cardinal push to help to lose weight as fat can be stored for long and it is hard to burn them. Lifestyle and dietary changes take a lot of time and effort. Also, when the weight is out of control and increases the risk of various other health issues like leaky gut, diabetes, etc., it is important to act fast and smart. For now, the gastric bypass operation is one of the top treatments for substantial weight loss.
