To maintain a healthy weight medical professionals emphasize that diet and exercise are key. If you want to lose weight, you must control calories and expend more by exercising. This has been the standard approach for decades. Recent research is telling a different story.
A growing number of studies, including one published in Medical News Today, are finding that for those who are obese, weight-loss/bariatric surgery may be more effective at reducing body weight than the old idea of changing habits and watching what you eat. The findings also suggested that bariatric surgery also increased remission rates in obese patients with Type 2 diabetes as well as heart disease.
Bariatric surgery helps you lose weight and lowers your overall risk of associated medical problems in one of two ways:
- Restriction. Surgery is used to physically limit the amount of food the stomach can hold, which limits the number of calories you can eat.
- Limiting the absorption of nutrients including calories. Surgery is used to shorten or bypass part of the small intestine, reducing the amount of nutrients and number of calories the body absorbs.
Some of the more popular weight-loss surgeries are:
- Gastric bypass – involves the creation of a small pouch in the top of the stomach. The pouch is the only part of the stomach that receives food. The small intestine is then cut a short distance below the main stomach and connected to the new pouch. Because food now bypasses a portion of the small intestines, absorption and calories are reduced.
- Gastric banding – involves placing an inflatable balloon (band) around the top part of the stomach; this creates a small stomach pouch above the band with a narrow opening to the rest of the stomach. A port is then installed under the skin. By injecting or removing fluid, the band/balloon can be inflated or deflated, controlling the amount of food the stomach can hold.
- Sleeve gastrectomy – In this approach, part of the stomach is separated and removed. The remaining section is formed into a tube-like structure; the smaller stomach cannot hold as much food. It also affects the production of hormones that produce hunger.
Why does bariatric surgery appear to be the preferred option over other weight loss options for those considered obese?
It appears to all come down to the success rates of changing old habits. Unfortunately, only slightly more than 5 percent of people are successful in changing their lifestyles on a long-term basis. Health experts claim that the overall risks associated with obesity which include heart disease, high blood pressure, Type 2 diabetes and other life threatening conditions, outweigh the risks and complications of surgery.
Weight-loss surgery isn’t a magic bullet or an easy fix by any means, but research shows it may be the best answer for many people suffering from severe obesity and the deadly health conditions that often accompany it.
