Bariatric surgery

life science Maturity 11-13 Next article →

Bariatric surgery is a group of medical procedures used to help people manage obesity. This type of surgery is very important for people when diet and exercise are not enough. It can help reduce many health problems that come with being very heavy. These issues include things like heart disease and type 2 diabetes. Some people even find that it helps them feel better mentally. By helping the body work differently, these surgeries can change a person's health for the long term.

These surgeries work in a few different ways to help a person lose weight. Some procedures, called restrictive surgeries, make the stomach much smaller. This helps a person feel full after eating much less food. Other methods are called malabsorptive procedures. These change how the body takes in nutrients like fats and proteins. Some surgeries even change gut hormones. These hormones are signals that tell the brain if a person is hungry or full.

Doctors have used different rules to decide who should have this surgery over the years. In 1991, a statement from the NIH said people needed a BMI over 40 to qualify. BMI is a way to measure body size. Over the last thirty years, new research has shown how effective these tools are. In October 2022, new groups like the ASMBS and IFSO updated the rules. Now, adults with a BMI over 35 can be considered for surgery. People with a BMI between 30 and 35 may also qualify if they have metabolic syndrome.

There are many specific ways to perform these surgeries. One common type is the gastric sleeve, which makes the stomach look like a long sleeve. Another is the Roux-en-Y gastric bypass, which creates a new path for food. There is also a procedure called biliopancreatic diversion with a duodenal switch. Different types result in different amounts of weight loss. For example, one study showed the duodenal switch helped people lose about 74.1% of their excess weight. Gastric banding is another option that is less invasive.

This surgery can lead to very big changes in how long a person lives. A 2021 study found that surgery helped reduce the risk of death for many adults. For obese adults with diabetes, the median life expectancy was 9.3 years longer. For those without diabetes, the gain was about 5.1 years. The surgery also helps the body manage type 2 diabetes much better. In fact, 85% to 90% of people saw their diabetes resolve after the procedure. It is a powerful way to help the body find a healthier balance.
