How Should You Eat After Gastric Sleeve Surgery? What Should You Eat?

Gastric sleeve, also known as sleeve gastrectomy or stomach reduction surgery, is a surgical procedure performed for individuals suffering from severe obesity, in which a large portion of the stomach is removed. This restricts the amount of food patients can consume and also reduces the sensation of hunger, as the area where ghrelin—the hunger hormone—is secreted is largely removed. However, for a successful and healthy process, post-operative nutrition is just as important as the surgery itself.

Pay attention to the nutritional stages.

Post-operative nutrition begins with clear liquids. It then progresses to liquid, pureed, and solid food stages according to the healthcare team's protocol. The timing for transitioning to each stage should be determined based on your dietitian's recommendations.

Do not neglect protein intake.

Consuming sufficient protein is important for preserving muscle mass during rapid weight loss and supporting the healing process. Your individual daily protein requirement should be determined specifically for you by your dietitian.

Spread your fluid consumption throughout the day.

Adequate fluids should be consumed in small sips, spread throughout the entire day. During the post-operative liquid phase, there should be a 2-hour interval between each type of liquid consumed. One glass of liquid should be consumed over the course of an hour. Once you transition to the solid food phase, there must be at least 15 minutes between meals and fluid intake. Separating solids and liquids in this way is a crucial rule for those who have undergone gastric sleeve surgery.

Do not skip your vitamin and mineral supplements.

Deficiencies in certain nutrients may develop after gastric sleeve surgery. In addition to any prescribed medications, you should take the recommended vitamin and mineral supplements to prevent a weakened immune system. Furthermore, regular blood tests should be conducted to monitor your health.

Gastric sleeve surgery is the beginning of a journey. For long-term success, regular doctor-dietitian follow-ups and sustainable nutritional habits are essential.
