Gastric Sleeve Surgery Post Operative Guidelines

Gastric Sleeve Post-Op Diet Guidelines

Vertical Sleeve Gastrectomy (VSG), also called Gastric Sleeve, is an impressive surgical treatment for obesity with quick weight loss results and low complication risk. You have made a commitment to acquire this life-changing tool and you are on your way to a healthier life.

To have a successful gastric sleeve surgery, patients will need to follow strict guidelines. These guidelines will help you lose weight, minimize complications, risks, and even unwanted side effects.

Steps to Follow After Gastric Sleeve Surgery:

  • Exercise – Patients who exercise will accelerate weight loss and reduce side effects. Exercise will also increase patient morale and reduce depression. Patients should exercise for 30-35 minutes, 4 or 5 days per week.
  • Daily Meals – Patients will need to focus on three regular meals and healthy eating habits. Please reference our gastric sleeve diet to learn more.
  • 64-Ounces of Water – Patients, will need to consume at least eight glasses of water per day (more if the day is humid).
  • Daily Vitamins – Patients will need to consume the necessary daily vitamins required for post-operative patients.
  • 60-80 grams of Protein – Patients, will need to consume 60-70 grams of protein a day, men will need to consume 75-85 daily grams.
  • Doctor Visits – Patients will need to honor and follow up with all the necessary doctor visits.
  • Eating – Patients will develop all of the necessary dieting rules after surgery, these rules are designed to help reduce complications and side effects.
  • Minimize Carbs – Patients need to watch and minimize their intake of carbohydrates.
  • Weighing – Patients shouldn’t weigh themselves more than a few times a month. Patients need to think and behave in a comprehensive manner.

Weight Loss Plateaus

Most times patients who are in weight loss plateaus can quickly adjust their lifestyle to jump off the plateaus. Patients consuming too many carbohydrates can easily be stuck on a plateau. Minimizing carbohydrates will typically break the weight loss plateaus – try exchanging carbohydrates with protein and fiber, which will keep you feeling fuller longer.

If you’re undergoing a weight training program/exercise regime, you could be stuck on a weight plateau. However your plateau could be specious or not legitimate, muscle weighs more than fat and patients can easily mislead into believing they are not losing fat when they are. It’s important to look at your body to see how you’re improving.

Exercise Guidelines

For the first 30 days, patients should not engage in strenuous activities including weight-lifting, running, or ab-crunches. We recommend that patients start by walking for 20 minutes for the first fourteen days after the surgery. After 15 days, patients can work up to 30-40 minutes of exercise per day.

  • Swimming – Wait at least 15 days before using the tub or the pool. Wounds can easily be infected if the wound has not fully healed. Overall, swimming is an excellent exercise that can include resistance training.
  • Weight Lifting – Wait at least 30 days after surgery to include lite resistance training. Use weights you can manage, and still incorporate cardiovascular exercise.

Vitamins and Supplements

After gastric sleeve surgery, patients will need to start a vitamin and supplement regimen for life. Common in restrictive bariatric surgeries are deficiencies in essential vitamins and minerals. Patients will need to take the following supplements:

  • Multivitamin
  • Vitamin B12
  • Calcium


Mexico Bariatric Center has developed multi-vitamins specifically for Gastric Sleeve patients according to  ASMBS guidelines. MBC highly recommends the patients to take these multivitamins for the first year after surgery and beyond for successful weight loss. Here are the highlights:

  • Make sure the vitamin includes folate (at least 400 mcg daily required) and iron.
  • Menstruating women or patients with anemia should take a multivitamin with supplemental iron.
  • Approved Multivitamins: Centrum Performance, Flinstones, Costco vitamins, and various other brands available at stores internationally.

Vitamin B12:

  • Patients will need to supplement B12 in their diet, a deficiency is somewhat common and can lead to serious neurological problems.


  • Patients will need to take a supplement of calcium/vitamin D complex. Supplements can help prevent osteoporosis.
