2 Week Pre Op Liquid Diet Gastric Sleeve

One of the most important parts of your digestive system will be altered by gastric sleeve surgery, so you need to prepare for it after surgery, depending on your health and BMI.
Surviving The Pre Bariatric Surgery Diet
Foods for 2 weeks before gastric sleeve surgery. You need to lighten your stomach and liver during this diet. If you follow his instructions, you can meet your gastric sleeve pre-surgery nutritional goals.
You should increase your protein intake to 60 grams with less meat and fish, eat more fiber-rich vegetables, and drink more water. Don’ts – Consuming caffeine, carbohydrates, sugary foods and drinks, and carbonated beverages. Caffeine increases appetite, and carbonated drinks can cause gas and bloating.
You can use sugar free products. Low calorie drinks without caffeine or sugar, sugar free jelly, sugar free popsicles, low calorie healthy snacks and more.
2-3 days before the procedure, additional changes are made in the diet. Leave solid food for a while and switch completely to liquid food. A liquid diet for the gastric sleeve will help you prepare for the first two weeks after the operation.
Nutrition In The Pre Operative Period Of Bariatric Surgery
Don’t be fooled by the word “liquid”. Drink only pure liquid. For example, chicken or vegetable soups, protein shakes, pure tea, unfiltered juices, etc.
“Why do I have to go on a diet before I get a tummy tuck?” Wouldn’t it be better to go on a diet then? “BMI greater than 50 or patients with fatty liver disease require gastric sleeve preoperative treatment.
Also, the stomach must be empty for the procedure. Yes, please stop eating, drinking and smoking the day before the surgery. However, if you eat a lot of hard-to-digest foods, it may still remain in your stomach.

Failure to eat before anesthesia and inform the surgeon can lead to negative results. To prevent this, the stomach is examined using endoscopy before anesthesia is administered. If the surgeon finds out that you have eaten, the operation should be postponed.

When you eat a pre-gastric diet, your body uses up excess glycogen stored in the liver. When the glycogen stores are used up, the liver becomes smaller and softer. This makes the operation easier.
Your calorie intake should be 1200-1400 calories for the last 2-3 days to prepare for gastric sleeve surgery and post-surgery diet. Most of your calories can come from protein shakes. Of course, to get the best nutrition from your sleep, you need to get a high-quality protein powder.
So how long do you need to eat before gastric sleeve surgery? Ideally, the food before the gastric sleeve should be two weeks. If the patient is very serious or has a lot of fat in the liver, surgery is not possible and may take up to three weeks.
If you mess up your diet before gastric sleeve surgery, your liver may not shrink enough to make the surgery safe and easy. If you eat too much, you won’t be able to empty your stomach in time. During the procedure (before anesthesia is given), your surgeon can see if you ate during the endoscopy. This may delay the operation. In other words, long-term nutrition is needed.
Diet After Gastric Bypass: Nutrition Planning
Patients with body mass index (BMI) above 50 should follow this diet. Yes, it is weight loss surgery, but a higher BMI increases the risk of complications during and after surgery. Most patients who require this surgery may have fatty liver disease. Fatty liver is an enlargement of the liver which makes surgery difficult. Therefore, you should have an ultrasound examination to find out if your liver is enlarged. In this case, you need to carry out nutritional therapy before gastric bypass surgery.
So how important is diet before gastric sleeve surgery? Some surgeons ask their patients to follow this two-week diet to make eating easier after surgery. When the patient’s liver is very thick, it becomes very difficult to move to reach the stomach. In such cases, the patient’s BMI is usually over 50, and the higher the index, the higher the risk.
Some surgeons do not require nutritional therapy before gastric sleeve because it has little or no effect on the operation. If the patient’s liver is not very thick and strong, it is easy to treat using modern technology. Although not necessary, some patients may prefer this diet. You can do this as long as you consult a nutritionist and do not starve your body. You can follow the same diet guidelines for 7 days before gastric bypass surgery.

This preoperative meal is intended to prepare the patient for surgery and/or postoperative meals. Everyone has their own body type.

Let’s say you follow this diet. Maintaining a “liquid diet” for a long time is not difficult. A sudden change of liquid to solid can lead to weight gain. Also, shocking the stomach in this way can cause constipation. Your stomach will not shrink in a short time. If this diet is not controlled, it can lead to malnutrition in the long run.
Diet should be adjusted according to your overall health. For example, if you have PCOS, avoid fried foods, sweets, and refined carbohydrates. Some foods like the following should be avoided and therefore you should consult a nutritionist to get the right diet. Remember that improper diet or lack of essential nutrients can only cause harm.

Caffeine is really beautiful. The smell, the taste… it’s great, but it doesn’t help before or after the surgery. Caffeine dehydrates your body. You need to stay hydrated before and after surgery. Caffeine also stimulates appetite. You can call it appetite. Before the operation, you need to start fighting the appetite.
Pre Bariatric Surgery Liquid Diet
The liver should be relaxed before the operation. If so, it’s better to take it slow. Avoid drinking alcohol for 2 to 3 days before the surgery. In this case, additional anesthesia may be required. Alcohol dehydrates the liver and dehydrates the body. This can lead to serious complications during and/or after the surgery.
Limit one or two glasses of low-calorie alcoholic beverages, such as gin and tonics, during the two-week diet.
Ideally, you should stop smoking 1 to 5 months before your surgery. If this is difficult, try to smoke less than usual and stop at least 15 days before the surgery.
If you still can’t quit, smoking before and after is more important. You should avoid eating and drinking as mentioned one day before the surgery. To avoid nausea and other post-operative complications, please refrain from smoking before your surgery and after midnight the day before your surgery.
