Will I Gain Weight Again After Gastric Sleeve Surgery?

20% in America, 25% in Europe, 40% weight in Turkey is taken again.

There are three reasons:


The most important reason is that the surgery is done personally, so the experience of the doctor is very important. If you could not lose the expected weight in the first year after surgery, the weight gain is related to the surgery. In the calculation, you should give at least 40% of your excess weight in the first year.

2.Changing your eating habits

This is true for the first two years. This is one of the most critical questions about sleeve gastrectomy for patients. First of all, we need to state that the risk of regaining weight in patients after sleeve gastrectomy is extremely low.

However, after surgery, patients should only consume food at the specified meals, not neglect to eat at least 3 meals a day, and especially abandon the habit of snacking between meals. In case of changing old eating habits and avoiding the consumption of high-calorie foods, there will be no weight gain again. In a sense, we can say that the answer to this question is actually given by the patient.

Regardless of which obesity treatment method is preferred, if the surgery is successful, it will be very easy to change these habits with the help of a dietician in this period, since you will not have the desire to eat in the first year. First of all, the patient needs to change his eating and living habits.

Weight loss should not be expected in cases such as continuing old eating habits and leading a sedentary life. On the contrary, even more weight gain may occur. Patient follow-up is of great importance in obesity surgery. During the follow-up of the patient, the weight gain action is also reviewed and the diet list can be revised accordingly.


If your operation is good at the end of two years and you are on a good dietitian, you have reached your ideal weight. Changing your eating habits and gaining weight after this time is entirely a patient mistake. Therefore, we say that follow-ups should be continued for at least 5 years. The patient should be in constant communication with the clinic.

The hair loss rate of patients who are followed by a good dietician is 10% and it starts in the 3rd month and passes the 4th. One of the most curious issues of patients about sleeve gastrectomy is hair loss. We can also state that this issue causes serious anxiety in patients. Hair loss problem occurs in 40% of patients after surgery.

We can only state that the number of people who do not want to experience this problem and cannot make a decision for surgery and continue to live with obesity problem is quite high. However, there is a very important element that is overlooked here. It is that the hair loss problem is completely temporary. At the same time, we would like you to know that we have taken every precaution to address this problem.

After this operation, the problem of hair loss begins between 3 and 6 months, and hair loss usually stops after 6 months. Of course, in order for this problem to be temporary, maximum attention should be paid to nutrition. If a type of surgery that prevents vitamin and mineral absorption is preferred, the risk of hair loss may be slightly higher.

The regrowth of the lost hair takes between 1 year and 1.5 years. If there is no new hair during this time, it should be considered that there is a different problem. At the same time, if there is no hair loss after 6 months after the operation, then it should be considered that there is a different problem.

Generally, hair loss occurs when there is a decrease in protein, zinc and iron levels. Hair loss problems due to gastric sleeve surgery do not need treatment. Since it is a temporary problem, it is possible to grow new hair after a while without the need for medical treatment. Continuing to live with excess weight while worrying about hair loss means taking the risk of more serious health problems. For this reason, it will be beneficial for those who have obesity problems to make an appointment for treatment as soon as possible.

Is Suture Made in Gastric Sleeve Surgery?

As is known, approximately 70-90% of the stomach is removed in this surgery. A stapler device is used to cut a part of the stomach. In our clinic, after the incision is made with a stapler device, the remaining part is stitched manually using special medical sewing threads (special thread called V-Log).

Thanks to this special technique, we have minimized the risk of both leakage and bleeding after surgery. Therefore, the purpose of this surgery is to take a part of the stomach and this is not possible without the incision. The application of the incision also necessitates the stitching process.

Will I have pain after the surgery?

However, it is not possible for the patient to feel any pain during the incision and sewing process. Because the surgery is performed under anesthesia. When the patient is out of anesthesia, the entire surgical process is already completed. The reason for the absence of pain in stomach and intestinal surgeries is that the stomach and intestine do not have pain against cutting the nerves, only if there is air and swelling in it, you will feel pain. If gas in the stomach and intestines is the cause of postoperative pain, pain will occur.

Why Should I Have Gastric Sleeve Surgery?

Excess weight can be the only root cause of too much disease. The only complaint of those who have obesity problems is not decreased quality of life or self-confidence problems. It should not be forgotten that almost all organs of the body, especially cardiovascular diseases, are affected by excessive aging.

Just living a healthy life can be the most common answer to the question of “why should I do it” about sleeve gastrectomy. Surgery makes it easier for patients to lose weight and therefore gives patients hope for a brand new life. With weight loss, the risk of dozens of diseases decreases, and patients have a much better quality of life. As a result, when it comes to getting rid of the obesity problem, it should not be regarded only as ‘losing weight’. It also means lowering the risk of many diseases.
