Helios International

Helios International represents the scale, expertise, and sophistication of Europe's leading hospital networks applied to the treatment of severe obesity and metabolic disease. With over 80 hospitals, more than 80,000 healthcare professionals, and specialized obesity centers distributed across Germany, Helios operates at a volume and with an infrastructure few single institutions can match. Yet scale alone does not distinguish Helios; what sets the network apart is that its multidisciplinary approach to bariatric surgery remains grounded in evidence, guided by experienced metabolic surgeons, and organized around the principle that obesity is a chronic disease requiring long-term medical partnership, not a surgical quick fix.

Europe's Largest Obesity Treatment Network

Helios Berlin-Buch alone treats approximately 800 bariatric surgery patients annually—a volume that reflects both patient trust and operational mastery. This scale brings undeniable advantages: high-volume centers accumulate experience that single-procedure specialists cannot match; complications are managed by teams that encounter them regularly and have refined protocols to address them; and surgical outcomes are tracked systematically against national and international benchmarks. Yet Helios distinguishes itself not by celebrating volume alone, but by embedding that volume within a rigorous framework of multidisciplinary assessment, evidence-based decision-making, and long-term patient engagement. Bariatric surgery at Helios is not a transaction; it is the beginning of a medical relationship structured to support sustained weight loss and metabolic improvement.

• 800+ bariatric surgery patients treated annually across Helios network
• Helios Berlin-Buch recognized as the largest obesity center in Germany
• Multiple specialized obesity centers across the country (Berlin-Buch, Wuppertal, Stralsund, Krefeld)
• Systematic outcome tracking and continuous quality improvement across all centers

Interdisciplinary Excellence: Surgery Within a Broader Medical Ecosystem

The bariatric surgery consultation process at Helios reflects an understanding that weight loss surgery succeeds only when the patient is ready—psychologically, metabolically, and behaviorally—for the commitment it demands. The interdisciplinary team includes experienced surgeons, endocrinologists specializing in metabolic disease, psychosomatic physicians trained in obesity-related psychological factors, and nutritional counselors. This breadth of expertise means that the surgical decision is not made in isolation. Before any operation, patients receive thorough assessment of metabolic status (including diabetes control, hormone function, and comorbid metabolic conditions), psychological readiness and support capacity, nutritional baseline and capacity for dietary adjustment, and cardiac and respiratory fitness for surgery.

Dr. med. Oliver Stumpf, Chief Physician of Metabolic and Bariatric Surgery at Helios Berlin-Buch, articulates a philosophy central to the network's approach: "Bariatric surgery is not only about weight loss." Obesity, in this framework, is understood as a multifactorial condition—involving genetics, metabolism, psychological factors, and behavioral patterns—that requires a multifactorial response. Surgery is a powerful tool for reducing hunger signals and caloric intake, but only when embedded within medical support, nutritional guidance, and psychological care does it produce durable metabolic improvement.

• Surgical expertise combined with endocrinology, psychosomatic medicine, and nutrition
• Comprehensive preoperative psychological and metabolic assessment
• Focus on patient readiness and behavioral capacity for post-operative adherence
• Ongoing multidisciplinary follow-up extending years beyond surgery

Minimally Invasive Technique and Individualized Surgical Selection

Approximately 70 percent of all bariatric surgery procedures performed at Helios are gastric sleeve operations, a technique in which the stomach is reduced to a slender tube, simultaneously reducing both meal capacity and the production of hunger-promoting hormones. This predominance reflects both the efficacy of the procedure and Helios surgeons' expertise in performing it safely. Yet Helios also offers gastric bypass and other metabolic procedures for patients whose anatomy, metabolic status, or comorbidities make alternative approaches advantageous.

Where feasible, Helios performs these procedures using minimally invasive (laparoscopic) techniques, reducing incisional trauma, postoperative pain, and recovery time compared to open approaches. The network's high volume ensures that minimally invasive expertise is distributed across multiple centers, so patients benefit from consistent technical proficiency regardless of which Helios facility treats them. This standardization—coupled with continuous training and quality monitoring—contributes to the network's reputation for safety and reliability.

• Minimally invasive (laparoscopic) approach standard for all major procedures
• Surgeon expertise distributed across multiple high-volume centers
• Standardized protocols ensuring consistent quality across the network
• Individual procedure selection based on patient anatomy, metabolism, and comorbidities

Comprehensive Patient Support: From Consultation to Rehabilitation

The patient experience at Helios extends well beyond the operating room. The International Office manages all logistics—treatment inquiry, appointment scheduling, visa support, accommodation arrangements, and travel coordination—in multiple languages (Arabic, English, French, German, and Russian). This comprehensive support reflects the recognition that international patients face organizational barriers to accessing care, and removing those barriers is essential to building trust and enabling successful treatment.

Post-operative care is equally structured. The Helios network provides rehabilitation services, ongoing nutritional counseling, and metabolic monitoring designed to support sustained weight loss and management of any emerging complications. The "Comfort Departments" at Helios facilities ensure that the recovery environment is not merely clinical, but supports dignity, privacy, and emotional wellbeing during a significant life transition.

• Multilingual international office managing all patient logistics
• Comprehensive visa, accommodation, and travel support services
• Structured post-operative rehabilitation and ongoing nutritional counseling
• Comfort departments designed for dignified recovery and long-term patient engagement

Why Patients Choose Helios

Patients who select Helios consistently cite several factors: the network's reputation as Europe's leading obesity treatment organization; the accessibility of care (multiple centers reduce travel burden); the evidence that surgical teams are experienced and complication rates are closely monitored; and the sense that the entire system—surgeons, endocrinologists, psychosomatic physicians, nutritionists, international coordinators—is organized around their success. Many patients arrive after failed attempts at weight loss through diet and medication alone, or after bariatric procedures at lower-volume centers with disappointing results. They describe discovering Helios and feeling, for the first time, that obesity was being addressed not as an individual moral failing, but as a chronic disease deserving the full attention of an experienced, multidisciplinary medical team.

Helios International's approach to bariatric surgery succeeds because it balances the efficiency and reliability that come from operating at scale with the individualization and humanity required for sustainable weight loss and metabolic recovery. In obesity care, where patients have often internalized shame and experienced repeated disappointment, this balance translates directly into the trust and engagement that define successful long-term outcomes.
