Gastric bypass patients usually lose a lot of weight very quickly after surgery. Within 3 months, the average patient loses about one-third of their excess weight. By the 1-year mark, almost two-thirds of the excess weight will be gone.
The upper small stomach is connected to the small intestine brought from below into the chamber. Ir Gastric Bypass ilim is intended to decrease both the person’s eating and the absorption of the food.
the United States the most common method of gastric bypass is proportionally more preferred due to the tendency to decrease the gastric tube surgery. Experience shows that the most disadvantage of this method is that it is technically very difficult to switch to a second method in the case of weight gain after gastric bypass. Although the need for second surgery after gastric bypass is less compared to the tube stomach method, transition to the Duodenal Switch, which is the most successful method for both diabetes control and effective and permanent weight gain, is much easier after the tube stomach.
Many patients reach “peak” weight loss between 1 and 2 years, then gain a little back (more about Weight Regain in the “Downsides” section below). But long-term results are still impressive, with the average patient keeping about 60% of their excess weight off after 5 years.
Keep in mind that these are averages – “middle of the road” results. Patients who eat the right foods, exercise regularly, and follow their surgeon’s advice can lose even more, while patients who veer off-track lose less.
