Gastric Balloon in İstanbul
Türkiye's economic, cultural, and healthcare hub, Istanbul is the country's most populous province with 15,655,924 residents (TÜİK ADNKS 2024). This metropolis bridging the Asian and European continents is Türkiye's primary gateway for international patient flow. Türkiye has the highest obesity prevalence in the WHO European Region (32.1%; WHO 2022), with the share of overweight and obese individuals reaching 66.8%. The Allurion swallowable gastric balloon program is offered at 37 authorized clinics in Istanbul.

Istanbul: Türkiye's Economic and Healthcare Capital
Istanbul alone produces 30.4% of Türkiye's gross domestic product (TÜİK Provincial GDP 2023). This economic weight positions the city at the intersection of business, finance, and the service sectors, while also shaping demand for healthcare services and expectations around access. The high concentration of corporate professionals, long working lives, and urban living conditions create fertile ground for weight management demand to be especially pronounced in Istanbul.
Bridging the Asian and European continents, Istanbul, with its 39 districts — 25 on the European side and 14 on the Asian side — is one of the world's rare examples of a metropolis spread across two continents. This geographic distinctiveness brings with it a distributed healthcare infrastructure that makes clinic access possible from numerous areas such as Kadıköy, Beşiktaş, Üsküdar, Bakırköy, Şişli, and Ataşehir. The Marmaray, the Istanbul metro, and the bridge connections link both sides of the city within practical travel times.
Türkiye welcomed 1.5 million health tourists in 2024, with Istanbul serving as the primary destination in this picture (Turkish Ministry of Health 2024). Individuals arriving from the Middle East, Russia, the Balkan countries, and Central Asia choose the city because of Istanbul's geographic proximity, well-established healthcare infrastructure, and international flight connections. This dynamic forms the structural rationale for why the Allurion authorized clinics in Istanbul are able to reach both domestic patients and an international visitor base.
Istanbul is also Türkiye's most intensive corporate business center. Long working hours, high stress, and a sedentary office life create fertile ground for weight management demand to become especially pronounced in large cities. In this context, the Allurion program — completed in 15 minutes and not disrupting daily routines — offers an option compatible with Istanbul's active business life.
Weight Management in Istanbul: The Metropolitan Dimension of the National Picture
Türkiye has the highest obesity prevalence in the World Health Organization European Region (32.1%; WHO 2022). According to the national screening by the Society of Endocrinology and Metabolism of Türkiye covering the years 2017-2022, the co-occurrence of type 2 diabetes and obesity increased significantly within five years (PMID 40582352). This picture directly affects Istanbul, the country's most populous and economically most intensive province.
Across Türkiye, 20.2% of the adult population is obese (BMI ≥30), while 66.8% fall into the overweight or obese category (TÜİK 2022; WHO 2022). Obesity is directly associated with chronic diseases such as type 2 diabetes, hypertension, cardiovascular diseases, and sleep apnea. Urban stress, sedentary ways of working, and long working hours turn weight management in large cities into a public health matter beyond an individual priority.
GLP-1 receptor agonists became widespread during this period; however, according to a meta-analysis covering 18 randomized controlled trials and 3,771 patients, an average regain of 5.63 kg is observed when medication use is discontinued (PMID 41399474). It has also been reported that the combination of the intragastric balloon with GLP-1 agonists shows a synergistic effect (PMID 41212463). These findings constitute evidence that demand for non-surgical and drug-free options is rising in large centers such as Istanbul.
According to the WHO 2022 European Region report, Türkiye is the country with the highest obesity prevalence in this region (32.1%; WHO 2022). With its 15,655,924 residents, Istanbul forms the most critical focal point of this health agenda; 37 Allurion authorized clinics are positioned across all districts of the city with the capacity to respond to this priority.
Healthcare Infrastructure in Istanbul
Istanbul is the province with the most comprehensive healthcare infrastructure in Türkiye. Numerous obesity treatment centers authorized by the Turkish Ministry of Health operate in the city; in these centers, a multidisciplinary team comprising endocrinology, general surgery, psychiatry, a dietitian, and a physiotherapist is mandatory. Spread across both the European and Asian sides, this clinical infrastructure forms a network accessible from every district of Istanbul.
The university medical faculties in Istanbul conduct comprehensive clinical research in the field of obesity and metabolic diseases. This research accumulation directly feeds clinical practice standards and positions Istanbul as a center where next-generation weight management technologies are adopted early.
The 37 Allurion authorized clinics in Istanbul are positioned across the city's two sides and various districts. This geographic distribution makes it possible for individuals coming from the European side to access clinics in nearby districts, and for those coming from the Asian side to reach clinics in their own areas without needing to cross between sides.
A systematic review and meta-analysis published in 2024 comprehensively demonstrated the short-term weight loss efficacy and safety profile of the Allurion swallowable balloon (PMID 39174862). Türkiye has a strong accumulation of clinical experience in the field of bariatric surgery worldwide (PMID 40257060). Drawing on this accumulation, the Allurion authorized clinics in Istanbul deliver the non-surgical, anesthesia-free program to high standards. Allurion received FDA PMA Class III approval on February 23, 2026 (P250023).
The Allurion Program in Istanbul: Step by Step
Initial Assessment: An initial assessment consultation is held with one of the authorized clinics on Istanbul's European or Asian side. The clinician evaluates your health history, your weight management goals, and your suitability for the Allurion program. For international patients, this consultation can also be conducted remotely.
Balloon Placement (15 min): The capsule, a small capsule containing a deflated balloon, is swallowed with a glass of water. The clinical team then confirms the capsule's position in the stomach; through the inflation process, the balloon gains volume. The entire procedure is completed in 15 minutes. It requires no anesthesia, endoscopy, or surgery. After the procedure, you can return to your daily life the same day, and to your work if needed.
4-Month Digital Follow-Up: Through the smart scale and the Allurion mobile app, the clinician conducts weekly follow-up remotely. This infrastructure ensures that follow-up continues uninterrupted during business trips, vacations, or periods of staying abroad — a critical convenience for Istanbul's busy business life and international travel patterns.
Program Completion: At the end of the 4th month, the balloon deflates on its own and is excreted from the body. The total 6-month program is then completed together with a 2-month lifestyle reinforcement period. FDA PMA Class III approval was obtained on 02/23/2026 (P250023).
Travel to Istanbul and International Patient Access
Istanbul Airport (IGA) is Türkiye's largest international airport, offering direct flight connections to hundreds of destinations worldwide. Travel from IGA to the city center (Taksim/Şişli) by metro takes approximately 35-45 minutes, and to different neighborhoods of the European side by taxi or private transfer it ranges from 30-60 minutes. Sabiha Gökçen Airport (SAW), with its location close to the Anatolian side, facilitates access to clinics on the Asian side; travel from SAW to Kadıköy or Ataşehir takes 30-45 minutes.
Thanks to its geographic position, Istanbul is on average a 3-4 hour flight from the Middle East, Russia, the Balkan countries, the Caucasus, and Central Asia. Individuals coming from this hinterland can enter Istanbul visa-free or with an e-visa from the Gulf countries, Azerbaijan, Georgia, Ukraine, Kazakhstan, and the Balkan countries. Türkiye welcomed 1.5 million health tourists in 2024, with Istanbul being the primary destination of this flow (Turkish Ministry of Health 2024).
For individuals coming to Istanbul from abroad for the Allurion program, a typical visit can be planned as follows: Before arrival, the initial assessment form is completed remotely via akillikapsul.com; the clinician confirms suitability and an appointment date is set. On the day of arrival, transfer from the airport to the clinic is provided; following the placement procedure completed in 15 minutes, the patient returns to their accommodation. Since no anesthesia is used, a return flight can be planned for the same day or the following day. The 4-month follow-up process is continued uninterrupted from abroad via the smart scale and mobile app.
For travel within Istanbul, the Marmaray, metro lines, the Eurasia Tunnel, and the bridges connect the European and Asian sides to each other in a short time. The public transportation network integrated with the İstanbulkart offers practical access to clinics in the city's various districts. The 37 Allurion authorized clinics in Istanbul have a wide geographic distribution across two continents; patients applying on the European side can begin the program at clinics in their own areas without crossing between continents. Visitors from more than 100 countries benefit from the right to enter Türkiye with an e-visa or visa-free.
