This FDA-approved weight loss treatment device is said to help people to stay thin even after consuming fatty foods by pumping it out of the stomach after every meal.

AspireAssist, the weight loss treatment pump that is designed for people with obesity - who may have gone through surgical and many other approaches but failed to lose weight.

It works like a pump with a hose attached to it. It is then inserted to the stomach and works to flush out the meal. Patients who have consumed a meal have to wait for 30 minutes to open the valve and drain the 30 percent calories they consume before it turns into fat.

The obesity device is described as reversible weight loss treatment and it has gained approval from Food and Drug Administration on June 14. AspireAssist is claimed to 'help calorie absorption' - a principle needed in weight loss treatment, FDA newsroom reported.

Regardless the effectiveness, FDA also states some warnings including vomiting, diarrhea and nausea. Thus, the use of the device has to be well monitored. Other side effects include tube removal that can cause bleeding and irritations.

There has been a debate on the FDA approved weight loss treatment device using this pump since it does not change the relationship between a person and the food. According to clinical professor at Albert Einstein College of Medicine, the device may enable people to lose weight but the idea of stomach pumping machine could cause horrific situation. Scientist also concerned on the fact that it mimicks bulimia behavior. People might also abuse the pump until the system is set by an expert.

The device maker, Aspire Bariatrics of King of Prussia, claims that the weight loss treatment device is intended to be used by obese people at the age 22 and above. These people have mass index of 35 to 55 that have failed to maintain weight loss, NBC News reported
