This guide covers everything about what to expect after gastric sleeve. After gastric sleeve surgery, most patients lose 15-20 pounds in the first month, 50-60 pounds by month 6, and 70-100+ pounds by month 12. But weight loss is just the beginning — you’ll experience dramatic changes in energy, health, confidence, and quality of life. Here’s your complete month-by-month guide from our bariatric surgeons at Lighter Dream in Tijuana.
Month 1: The Liquid Phase (15-20 lbs lost)
- Diet: Clear liquids transitioning to protein shakes by week 2
- Energy: Low — your body is healing. Rest is important

Vitamins You’ll Take Long-Term
Lifelong vitamin supplementation is essential: bariatric multivitamin (twice daily), calcium + Vitamin D, B12, iron (especially for women), and biotin for hair health.
According to the American Society for Metabolic and Bariatric Surgery (ASMBS), bariatric surgery is one of the most effective treatments for severe obesity and its related health conditions.
