Study Finds Troubles With Gastric Band Surgery

A study has found that nearly half of a group of patients who received gastric band surgery for weight loss over ten years ago had the bands removed because of medical complications.

The study is the first to track laparoscopic gastric band surgery outcomes over a long period. The bands eroded in almost a third of the patients, and sixty percent went on to undergo additional weight loss surgery in spite of the bands.

According to the New York Times:
“Researchers concluded that the adjustable gastric band surgery, which is growing in popularity in the United States, ‘appears to result in relatively poor long-term outcomes.’ The results ‘are worse than we expected,’ said Dr. Jacques Himpens … lead author of the new study.”

Furthermore, significant bone loss has been shown to occur in teens receiving gastric bypass surgery, the same result that occurs in adults receiving this more invasive type of stomach surgery. Researchers took bone density measurements every three months for two years after the teen’s surgeries and according to USA Today found that:

“Two years after the surgery, the bone mineral content of the 61 obese teens studied had declined, on average, by 7.4 percent.”

Key To Way Stomach Expands Found

Scientists believe they may have found a potential new way to treat obesity by stopping the stomach from expanding….CLICK & SEE

…….The stomach expands to accommodate the food we eat

They have identified two cell proteins that relax the gut and help accommodate a big meal.

In theory, a drug which blocked this relaxation would reduce a person’s ability and desire to gorge on excessive amounts of food.

The University College London study appears in the Journal of Pharmacology and Experimental Therapeutics.

The two proteins identified by the researchers P2Y1 and P2Y11 – control both fast and slow relaxations of the gut.

The human stomach has a “resting” internal volume of 75 millilitres, but by relaxing its muscular wall can expand to an internal volume of two litres or more.

This expansion is controlled by nerves inside the stomach wall which release molecules that stimulate P2Y1 and P2Y11, which are embedded in muscle cells, also in the gut wall.

New approach :

Researcher Dr Brian King said: “The mechanism of slow relaxation of the stomach might represent a future drug target in the fight to control weight gain and reverse obesity.

“We are looking to identify drugs that would block the P2Y11 receptor and, therefore, prevent slow relaxation of the stomach.

“As a result of blocking the P2Y11-based mechanism, meal size would be smaller, offering the person a better chance of regulating their food intake.”

Dr King said this would represent a new approach to weight control.

At present, gastric banding or stomach stapling are used to reduce the maximum volume of the stomach.

But these are tricky surgical procedures, and carry a risk of serious side effects.

Dr Ian Campbell, medical director of the charity Weight Concern, agreed that an alternative treatment for obesity would be useful.

He said major surgery such as gastric banding was expensive and risky, and although current drugs that focused on appetite suppression, or on reducing fat absorption by the body did work, their long term effects remained unclear.

“We still have much to learn about the complex way we control our appetite, and food intake,” he said.

“For many the use of medication can be an important help towards their weight loss goals, but lifestyle change remains the best way of controlling weight.”
