This is Joe from Belgium. I love to eat junk and cheesy food. lol... this habit of continuously eating led me to severe obesity. at just 25 years I had 88 kgs. My father was very worried about the continuous gaining of my weight. his friends told him about the Clinic Bariatric, and the extraordinary results patients got from there. I had my Gastric bypass surgery and lost more than 28 kgs in just 3 months. amazing results I have got. Thanks to Clinic Bariatric for their best services.

I must say this is the best experience ever in my life

5 50 Gastric Sleeve

Seven months ago, I had my gastric sleeve. Everything was very soothing. I went to Istanbul only for my surgery. To be very honest, I was very nervous about my surgery, but when I came to the clinic, I noticed that they provide their best services at a meager rate. All the staff members and doctors are concerned about the health of their patients. Within one week of hospital and & hotel stay, their clinic staff members very much cared about my health status, and I lost 42 kg in seven months. I must say this is the best experience ever in my life.

An unbelievable victory

5 50 Gastric Sleeve

I came from UK to visit Clinic Bariatric in Turkey. Almost 6 months ago, I had so many problems related to cardiovascular disease. And I was apprehensive about my health. My mother found clinic bariatric on the internet, and she counseled me about it. After that, I reached their patient consultant, and I found it very helpful. So, I came to know that due to excessive weight, I have cardiovascular disease, and they provide me with different weight-loss surgeries. I booked my surgery, and around four months ago, I did my gastric sleeve and lost 35 kg. That is an unbelievable victory, and my heart complication is very much less now.

The gastric sleeve is the best thing that ever happened to me

5 50 Gastric Sleeve

One of the best decisions, if I have ever made in my 30 years of life span, is that almost three months ago, I visited clinic bariatric and did my gastric sleeve. The experience of my surgery was quite good and comfortable. I am more than happy to tell all of you that in just two months I lost 28 kg. The gastric sleeve is the best thing that ever happened to me. Before that, I hesitated about my weight and looks, and now I am living a best and healthy life without any discomfort and hesitation.

I am very thankful for all the staff members and doctors who helped me throughout my session

5 50 Gastric Sleeve

I had a gastric sleeve three month ago at Clinic Bariatric, located in Turkey. The doctor and all the staff members are very friendly and good. Whenever I need them, they check me from time to time. The ambiance of this clinic is extremely comfortable. Now I reached my ideal weight, and the best part of my weight loss is that I easily fit on my small size dresses, which were impossible in the past. After surgery, when I first saw my figure in the mirror, I was extremely happy, and I have no words to describe my feelings now. I am very thankful for all the staff members and doctors who helped me throughout my session.

I am living a healthy life now that's all that I wanted

5 50 Gastric Sleeve

Last days I had gone through with my gastric sleeve. Before that, I had suffered from different health issues. The main reason that I was an obese man that promoted pain in my joints, and that's why I was not performing well in all my daily routine. Furthermore, most of the time, I felt insomnia. But now, apart from weight loss, I have observed many changes in my routine. I sleep on time now. That is a very good sign of a healthy life, and I lost around 17 kg. I am living a healthy life now that all that I wanted.

Gastric Sleeve (1 hour)

Gastric sleeve is a simple procedure. We access the abdominal area laparoscopically (keyhole surgery) and remove about 80% of the stomach by cutting it along its length. After sleeve surgery, the food you eat enters and exits the stomach via the same places as before (unlike gastric bypass), but you have a much smaller stomach. The sheath helps you lose weight in two ways. It reduces the capacity of your stomach and also changes the balance of hormones and proteins in the stomach. The change in the intestinal hormones, including GLP1, alters and reduces the appetite. Therefore, we expect patients with hives to lose weight quickly. It is important to note that your weight loss is not directly related to the size of your remaining stomach. The change in the bowel hormones will ease the weight loss, whether you have a relatively “tight” or “loose” sleeve.
