Gastric Sleeve Surgery or Sleeve Gastrectomy is a surgical procedure performed to lose extra weight. Around 80% of your stomach will be removed during this procedure. If you plan to undergo a Sleeve Gastrectomy, you should follow a highly restrictive diet for two weeks before your gastric sleeve surgery.
Diet before the gastric sleeve procedure is intended to decrease the size of the liver and weight to make the procedure more comfortable. In addition, diet after the gastric sleeve procedure helps you recover quickly from the surgery and avoid complications.
The postoperative diet involves different types, starting from liquids to the final protein-rich & low-calorie solid diet, which you should continue for life to achieve your weight loss goals.

Diet Before Gastric Sleeve Surgery
Overweight people tend to have fatty livers. Your liver is located adjacent to the stomach, so a larger liver increases the possibility of complications during gastric sleeve surgery.
However, the liver size can be reduced quickly. So, to make it happen, you need to follow a specific diet as suggested by the surgeon just two weeks before your gastric sleeve surgery. The diet decreases the volume of your liver, which makes your procedure safer, quicker, and easier. In addition, this diet helps you to get ready for a post-operative diet also.
A pre-operative diet for gastric sleeve aims to reduce calorie consumption, lower the intake of carbohydrates, and cut the sugar from your daily diet. Two days just before gastric sleeve surgery, you will be on a clear liquid diet and should completely avoid caffeine and carbonated drinks.
It is crucial to follow the two-week gastric sleeve pre-operative diet as instructed by your weight loss surgeon.
Your bariatric surgeon may suggest you take multivitamin supplements daily to ensure that your body receives the required nutrients.
Diet After Gastric Sleeve Surgery
Depending on the situation after surgery, the diet that will be recommended by the doctor varies from person to person.
Generally, post-gastric bypass diets are designed in stages so that you can gradually regain your appetite. The progression of stages depends on how quickly your body can heal and adapt to the new eating patterns. For example, it might take around two months to start eating your regular foods after surgery.
At every stage of the gastric bypass diet, every individual should be careful and follow the suggestions given by the doctor:
