Frequently Asked Questions
While gastric sleeve only reduces stomach size, gastric bypass both creates a smaller stomach pouch and reroutes the intestines. This dual mechanism produces greater weight loss and more significant metabolic improvements, particularly for type 2 diabetes.
Gastric bypass is technically reversible but is considered a permanent procedure. Reversal surgery is complex and rarely performed. Patients should approach this procedure with the understanding that it involves a lifelong commitment.
Yes. Because the procedure reduces nutrient absorption, lifelong supplementation with vitamins and minerals (including B12, iron, calcium, and vitamin D) is essential. MedProper provides a detailed supplementation plan tailored to your needs.
Most patients lose 60-80% of their excess body weight within 12-18 months. Long-term success depends on adherence to dietary guidelines, regular exercise, and follow-up care.
Clinical studies show that gastric bypass achieves type 2 diabetes remission in up to 80% of patients. The hormonal changes triggered by intestinal rerouting improve insulin sensitivity independently of weight loss.
