Prices in Germany are normally 65% below the cost of gastric bypass surgery in the US and are individually quoted. They include all medical expenses, the hospital stay, surgeon's fees, operation room fees, anesthesia, anesthesiologist's fees, medicine, nursing, semi-private room, meals, pre-op diagnosis, local phone and English TV.

It is well understood that Gastric Bypass surgery causes the mechanical restriction of food intake, but how does this account for food satiation of Gastric Bypass recipients?

In a study published by David E. Cummings and others, Gastric Bypass surgery was shown to reduce the levels of the hormone ghrelin by 77 percent of the normal weight person. Ghrlein is a hormone mostly produced by the stomach and is correlated with food intake in humans and laboratory rodents. This is a strong indication that the Gastric Bypass may inhibit the production of ghrelin.

In contrast people, who diet, have a higher level of ghrelin in their blood plasma. This may account for why so many dieters regain their weight.

Like other weight loss procedures, the Gastric Bypass procedure also has the benefits of reducing comorbidities, such as diabetes, hypertension (high blood pressure), and high cholesterol in the vast majority of the those, who undertake the surgery.
