    Losing Dozens of Kilos Permanently

    Gastric bypass surgery leads to long-lasting and massive weight loss mainly because the stomach's ability to store food is almost annihilated. Patients may experience a quicker feeling of fullness, which leads them to consume less food. It's essential to note that gastrectomy is a serious surgical procedure, and the resulting weight loss should be closely monitored by healthcare professionals.


    Patients need to follow specific dietary recommendations and receive regular medical follow-up to ensure that weight loss is healthy and controlled. Since Bypass surgery is solely applied to severe obesity patients, the weightloss is always very important and accounted for in many dozens of kilos.
