Gastric Sleeve in Turkey

Gastric sleeve surgery, also known as obesity surgery, weight loss surgery or vsg surgery, is performed on patients who have trouble losing weight with alternative methods, such as exercising or diets. Since obesity poses a risk for many health problems such as cardiovascular diseases, stroke, cancer and infertility, people with obesity problems should lose weight and approach their ideal weight to reduce the risk of the health problems listed. The best way to protect yourself from obesity-related health problems is to stay at the ideal weight and consult a specialist when you notice that you gain weight. However, people who already have obesity problems, are not helpless or desperate. These people should consult a doctor to live a healthier life and try to do what is necessary to reach their ideal weight. If you are asking “whats a gastric surgery?”, here we want to inform you about the operation in detail. 

Gastric Sleeve Turkey

In the gastric sleeve operation, approximately 80% of the stomach is removed by inserting various instruments through small holes opened in the abdomen, this is the reason wht it is also called stomach reduction surgery. The shape of the remaining stomach from the stomach sleeve is like the size of a banana. Reducing the size of the stomach limits the amount of food that can be consumed. In addition, as the stomach size is limited, hormonal changes are also rearranged to help lose weight. For example, hunger hormone (ghrelin), secreted from the removed part of your stomach, decreases by 70-80% after bariatric sleeve surgery. Thus you feel less hungry between meals and your feeling of full lasts longer. These changes help the patient stay at the ideal weight after surgery, but to maintain it, a multifactorial approach including nutrition, exercise and medical treatments is required.


You may wonder what is the best weight loss surgery, gastric bypass or sleeve? In both, the volume of the stomach is reduced  However, in gastric bypass surgery, the stomach is divided into two and the divided part is connected to the middle of the intestine. With this surgical procedure, food does not pass through the duodenum. But in the gastric sleeve, there is no change in the progression of food through the digestive system, thus it is more suitable for the natural functioning of human anatomy. 

Gastric sleeve surgery is usually performed laparoscopically. Laparoscopic surgery has advantages such as faster recovery time and fewer surgical scars. The surgery takes approximately 1-2 hours and the patient is observed closely in case of any complications. The patient is discharged within a few days, depending on the general condition. The surgery is irreversible since the stomach is reduced to a smaller size permanently.

 What You Need To Know About Weight Loss Surgeries | Sanamentum Turkey youtube play button



Gastric sleeve surgery requires following a strict diet during the recovery period. Since patients feel full with very little food, these foods must be of high quality, that is, foods rich in protein, minerals and vitamins.

Now that the stomach size is reduced, your eating habits will change so as not to slow down the gastric sleeve healing process. Patients should follow a special diet for 5 weeks then they can continue to eat normally but only with small portions slowly.  Because of the sensitivity of the stomach, patients will consume only liquid type of food in the first three weeks. Then they will continue with puree type of food for one week. Then they continue to eat what they used to, however, portions should be small and the patient should eat slowly.

Compliance with nutrition plans is of great importance to prevent complications that may occur after gastric sleeve surgery and to help heal wounds in the digestive system. You should learn to listen to your body and stomach while eating. Every patient is unique. What doesn't cause a problem for someone else may bother you. If you progress faster than normal in the nutrition program and experience problems, you should return to the previous stage and eat according to that stage for at least a few days.


First Week of Gastric Sleeve Surgery (Clear Liquid Diet)

It is the first step in post-operative nutrition. Patients can consume liquids below:

•    Water
•    Soups that are clear and grain-free
•    Protein Shakes
•    Herbal Teas
•    Diluted Juices

In the first week of gastric sleeve surgery patients should follow the rules written below:

•    They have to consume at least 1 litre of liquid that contains enough nutrition.
•    Liquids should be clear and grainless.
•    Patients have to consume one packet of protein powder to supply their body.
•    Soups must not have seasoning, spice, tomato paste, oil, lemon, onion or garlic. They may delay the healing of the stomach.
•    Every drink should be consumed with small sips and slowly, in order to avoid damaging the stomach. It is also important not to take too large a quantity while sipping. They can use a teaspoon for this. They should wait 1-2 seconds after each sip.
•    Drinks should be warm, not cold or hot.
•    Patients should not be dehydrated.

Second and Third Week of Gastric Sleeve Surgery (Liquid Diet)

During this period, the stomach is gradually healing, so, beverages can be drunk without diluting. If drinks such as soups have grain in them, patients should chew a lot before swallowing them. Patients can consume addition to the first week:

•    Blended soups
•    Yogurt
•    Milk
•    Warm Tea

In the second and third weeks of gastric sleeve Turkey patients should follow the rules written below:

•    Patients must consume their protein shakes every da or else recovery may slow down. 
•    Drinks should be warm, not cold or hot.

Diet Lists


Fourth and Fifth Week of the Weight Loss Surgery Turkey (Puree Diet)

From now on, patients can consume puree types of foods. The stomach is healing gradually but still, the patient should be careful about the portions. Foods that contain protein should be consumed first, then vegetables and fruits. During the puree diet period, foods should not be hard but can be chewable. Every meal should last thirty minutes. You have to eat 5-6 times a day. If you consume hard foods, you have to wait at least 30 minutes before you consume liquid foods. Patients should walk one hour every 4 days of the week. You should stop eating immediately when you feel full. You should not consume fried foods. Patients should avoid consuming carbonated drinks, tea, coffee and mineral water. Patients can consume:

• Vegetable dishes without meat 
• Grilled, steamed, roasted or boiled vegetables (by crushing them thoroughly or blending them) 
• Fruit yoghurt made with unsweetened fruit purees (banana, apple, pear) (can be consumed with fruit puree + yoghurt + protein powder)
 • Fish can be consumed steamed or boiled.

In this period, patients need to pay attention to the rules written below:

• Each new food should be tried alone. Do not try two different foods at the same meal. After eating, you should wait at least 3 days before trying the food that upset your stomach again.
• Acidic fruits such as orange, grapefruit; Sour fruits such as quince and pomegranate will not be consumed during this period either.
• The 30-minute rule for solid-liquid separation has now started. You should wait at least 30 minutes before consuming liquid food after consuming solid food. This rule will continue for life.

Fifth Week and After the Gastric Sleeve Surgery (Hard Food Diet)

After the fifth week, patients can start to eat hard foods but there are some rules. After the fifth week of recovery, patients can start eating hard foods that contain high protein and are low on calories. Sufficient protein should be consumed every day. You should not be dehydrated. Every thirty seconds, 200ml water is sufficient. These are the rules and important notes that you should consider during your recovery period. If you have any questions that you do not find the answer to above, you can always contact Sanamentum’s aftercare specialist assigned to you. 


Foods to Avoid After the Gastric Sleeve Surgery

1)    Empty-Calorie Foods: Sweets, chips, popcorn, and pretzels offer little nutritional value and can hinder your progress.

2)    Dry Foods: Nuts, granola, and dry cereal can be hard to digest and may cause discomfort. 

3)    Alcohol: Alcohol can irritate your healing stomach and interfere with your weight loss journey. 

4)    Refined Carbohydrates: Rice, bread, and pasta can lead to calorie-dense, low-nutrient meals.

5)    Fibrous Fruits and Vegetables: While essential, high-fibre choices like celery, cabbage, broccoli, and corn can be challenging to digest early on. 

6)    Sugary, Fizzy or Highly-Caffeinated Beverages: Soda and certain fruit juices are laden with empty calories and can disrupt your weight loss efforts. 

7)    Fatty Foods: Bacon, sausage, whole milk, and butter are calorie-dense and can lead to discomfort. 

8)    Tough Meats: Steaks, pork chops, ham, and hotdogs can be difficult to chew and digest.

9)    Heavily Seasoned or Spicy Foods: These can irritate your stomach lining and cause discomfort. 

10)   Microwave-Reheated Foods: Microwaving can alter the texture of some foods, making them difficult to digest.
